Welcome!
Thank you for choosing ABBYY FineReader!
We all need to input text into our computers from time to time, whether
it be newspaper/magazine articles, contracts, business letters, faxes, price
lists, or questionnaires. For years there was only one way to input print
ed documents – you had to type them in from the keyboard. Remember
the long hours you spent typing in text from one document or another?
What a great thing it would have been had the computer been able to
read the text by itself, straight from the sheet of paper.
Sometimes dreams do come true! FineReader Optical Character
Recognition (OCR) software enables your computer and scanner to do
just this – to read printed text by themselves.
But can’t the scanner do the job on its own?
No. The scanner only takes a photograph of the text and converts it into
a set of black and white dots (an image file), which cannot be edited
using word processing applications such as MS Word, WordPerfect, Word
Pro, etc. What is needed instead is an OCR system that looks for symbols
in each set of black and white dots, “recognizes” the letters in each sym
bol, and, finally, converts the image into text that text editors and desk
top systems are able to deal with.
So now I can input documents into my computer automatically?
Yes, now you can input documents into your computer automatically,
without having to retype them all out on your keyboard.
Enjoy!

Additional licenses
Following installation on a network server, you will need to add serial numbers if
FineReader is to be used by more than one user simultaneously:
1 Run LicSetup.exe from the folder Program files\ABBYY FineReader 6.0

method, SP 6 and IE 5.5 will be automatically installed on your system. To
avoid any difficulties related to the absence of these components, the system
administrator should check if both of these components are installed on the
network station prior to installation. If they are not installed, the system
should be updated before installing ABBYY FineReader.

Quick Start
In this chapter you will learn how to input a document without
having to know anything about the way in which ABBYY
FineReader works! You will also learn which windows and tool
bars are contained within FineReader.

How to input a document in less than a minute
1. Turn on the scanner if it has a separate power source to your PC.
Note: Many scanner models have to be turned on before you turn on the
computer.
2. Turn on the computer and start FineReader (
Start/Programs/ABBYY
FineReader 6.0 Professional
or Corporate Edition). The FineReader
main window will appear on your screen.
3. Place the page you want read onto the scanner.
4. Click the arrow to the right of the
Scan&Read button. Select the
Scan&Read Wizard item in the local menu.
The
Scan&Read Wizard is a special
Scan&Read/Open&Read mode during which you are
guided through each step of the scanning process. You
can use a sample image file which is contained in the
Demo folder, which, in turn, is located in the folder containing FineReader.
5. Follow the
Scan&Read Wizard instructions.
The document input process is made up of four steps: scanning, reading, spellcheck and sav
ing the recognized text.
Once scanning is complete, a “photograph”of the source page will appear in the
Image
window. The application then asks you to set the recognition parameters. Once this has
been done, it starts recognizing the image, analyzing its layout at the same time. Image areas
already recognized are highlighted in blue.
Recognized text is displayed in the
Text window, where it can be checked and edited. Once
you have checked the document, the
Scan&Read Wizard will prompt you to either send
the recognized text to the application of your choice, save it to file, or go on processing
more images.
The ABBYY FineReader Main window
FineReader performs all document processing in batch mode. A batch is a folder containing
images, recognized text files and other FineReader information files. Each scanned image is
converted into a separate batch page. If there are several images in a single image file (for
example, if you are dealing with a multipage TIFF), each file image will be converted into a
separate batch page.

When you start FineReader for the first time, the default batch is opened. You can choose to

What is an OCR system?
An OCR (Optical Character Recognition) system enables you to input printed documents
into your computer automatically via a scanner.
FineReader is an omnifont optical text recognition system. As a result it can recognize texts
set in practically any font without any prior training. FineReader features high recognition
accuracy and low sensitivity to print defects due to its incorporation of special recognition
technology based on the principles of Integral Purposeful Adaptive (IPA) perception.
The document input process can be divided into two stages:
1. Scanning. During the first stage the scanner acts as the computer’s “eye”. It
looks at the image and transfers it to the computer. The acquired image is
nothing more than a picture, a set of black, white, and color dots impossible
to edit in any word processor.
2.
Recognition. During the second stage FineReader carries out OCR image
processing.
Let’s take a closer look at the second stage.
FineReader OCR image processing involves analyzing the image file transmitted by the scan
ner (layout analysis) and recognizing each character. The layout analysis (selecting the
recognition areas, tables, pictures, lines, and individual characters) and image reading
processes are closely related. Page layout analysis is more accurate if the nature of the text
is known to the application.
As mentioned previously, the image recognition process is based on the principles of
Integral Purposeful Adaptive (IPA) perception.
z
Integrity – the identification of recognition objects based on a set of basic
elements and their interrelations.
z
Purposefulness – the generation and purposeful verification of recogni
tion hypotheses.
z
Adaptability – the system’s ability to learn and be trained.
These three principles determine the system’s behavior. The system generates a hypothesis
concerning a recognition object (a character, part of a character, or several glued charac
ters) and then accepts or rejects this hypothesis according to whether the structural ele
ments are present. These structural elements are computer equivalents of character parts
crucial for human perception (arcs, circles, dots etc.). The application then adapts itself to
the text according to the degree of accuracy attained. Purposeful searching and context
information enable the system to recognize even torn and distorted characters, rendering it
almost insensitive to print defects.
The final result is the recognized text that you see in the FineReader window, a text you
can edit and save in any convenient format.

Scanning
FineReader “talks” with scanners via the TWAIN interface. This is a universal standard adopt
ed in 1992 to unify the interaction of computer image inputting devices (such as scanners)
and external applications. There are two ways in which FineReader can “talk” with a scanner
via a TWAINdriver:
z
using its own interface: in this case use the FineReader Scanner
Settings
dialog to set scanning options; select Use FineReader interface;
z
using the scanner’s TWAIN interface: in this case use the scanner’s
TWAINdialog to set scanning options; select
Use TWAINSource inter
face.
Both modes have their advantages and disadvantages
When you select the Use TWAINSource interface option, the preview image option nor
mally becomes available. The option allows you to set the scanning area and tune brightness
precisely, and to see how changes affect the previewed image. Note, however, that different
scanners have different TWAIN driver dialogs. For instructions on how to use your scanner’s
TWAINdialog, consult your scanner’s documentation.
If you select the
Use FineReader interface option, you have access to the following addi
tional features: a) you can scan multiple images using scanners without ADFs; b) you can
save scanning options in the batch template file (*.fbt) and use them for other batches.
Switching from one mode to the other is easy:
z Select the Scan/Open Image tab in the Options dialog (menu
Tools>Options) and click the button of your choice – either Use TWAIN
Source interface
or Use FineReader interface.
Note: 1. The Use FineReader interface option may be unavailable (or disabled) in
the case of certain scanner models.
2. If you wish to see the
Scanner Settings dialog in Use FineReader inter
face
mode, select the Display options dialog before scanning item on
the
Scan/Open Image tab (Tools>Options).
Important: Consult the documentation supplied with the scanner to ensure it is set up
correctly. After connecting the scanner to the computer, don’t forget to install a TWAIN
driver and/or the scanner software.
30
ABBYY FineReader 6.0 User’s Guide
Page 31
To start scanning:
Click the 1Scan button or select the Scan item in the File menu. The
Image window containing a “photograph” of the scanned page will
appear in FineReader’s
Main window.
If you wish to scan several pages, click the arrow to the right of the
1Scan button and
select the Scan Multiple Images item
If scanning does not start right away, one of following two dialogs will open:
z The scanner’s
TWAINSource dialog. Check the scanning options and click
the
OK button to start scanning.
z The
Scanner Settings dialog. Check the scanning options and click the
OK button to start scanning.
Tip: To start recognition immediately after the source images are scanned, use the
Scan&Read or Scan&Read Multiple Images option:
Click the arrow to the right of the
Scan&Read button and select
either
Scan&Read or Scan&Read Multiple Images item in the local
menu.
FineReader will scan and read the images. The
Image window displaying a “photograph” of
the scanned page and the
Text window displaying the recognition results will appear in
FineReader’s
Main window. The recognized text may be exported to various external appli
cations and saved in various formats.
Setting scanning parameters
Recognition quality depends greatly on the quality of the scanned image. The image quality
may be improved by altering the main scanning parameters: resolution, scan mode, and
brightness.
The main scanning parameters are:
z Resolution – use 300 dpi resolution for regular texts (font size 10pts. or
greater) and 400600 dpi resolution for texts set in smaller font sizes (9pts.
or less).
z
Scan mode – gray.
Scanning in grayscale mode is best for recognition purposes. If you scan
your images in grayscale, brightness is adjusted automatically.
z
Scan mode – black and white.
Scanning in black and white enables the system to scan at a higher speed,
but at the same time some character information is lost. This may have an
31
Chapter 4. Acquiring the Image
Page 32
adverse effect on recognition quality in the case of documents of medium
tolow print quality.
z
Scan mode – color.
If you scan color documents that contain pictures, colored text, or colored
backgrounds, you may wish to retain the original colors in your electronic
document. Use the
color scan mode in this case. Otherwise use gray scan
mode.
z
Brightness – a medium brightness value of around 50% should suffice for
most cases. Some documents scanned in black and white mode may require
additional brightness tuning.
Note: Scanning at 400–600 dpi resolution (instead of the default 300 dpi) or scanning in
grayscale or color (instead of black & white) mode is more time consuming. In the case of cer
tain scanner models, 600 dpi resolution scanning can take up to four times longer than 300
dpi resolution scanning.
To set scanning parameters:
z If you wish to scan your images using the FineReader TWAIN interface,
select the
Scanner settings item in the Tools menu. The Scanner set
tings
dialog will then open. Select the scanning options of your choice in
the dialog.
z If you wish to scan your images using the
TWAINSource interface, your
scanner’s TWAIN dialog will open automatically when you click the
1Scan
button. Set the scanning parameters in the dialogue. Scanning options may
have different names depending on the scanner model used. For example,
for brightness the word “threshold", a “sun” symbol or a black and white cir
cle may be used. The options available will be described in full in your scan
ner documentation.
Tips on brightness tuning
The scanned image has to be legible. To check its legibility, view the image in the Zoom
window.
– an example of a good image (from an OCR point of view)
If you see that the scanned image is far from perfect (characters are glued or torn), consult
the table below to find out how you can improve image quality.
32
ABBYY FineReader 6.0 User’s Guide
Page 33
Your image looks like this: Possible remedy:
characters are “torn” or very light z Try lowering the brightness (this will make
the image darker)
z Try scanning it in gray mode (brightness
autotuning will then be used).
characters are distorted, glued, or filled z Try increasing the brightness (this will make
the image brighter)
z Try scanning it in gray mode (brightness
autotuning will then be used)
Scanning multipage documents
FineReader features a special scanning mode for convenient multipage document scanning:
Scan Multiple Images. You may scan as many pages as you wish in this mode. However,
note the following:
z If you scan your images using the
FineReader TWAIN interface, scanning
will be continuous. Once the application has completed scanning one page,
it will automatically start scanning the next.
z If you scan your images using the
TWAINSource interface, the TWAIN
dialog
of the scanner will not close once a page has been scanned, and the
next page can be placed onto the scanner immediately.
If you have a large number of pages to scan, there are two ways in which you can do this:
using a scanner with an Automatic Document Feeder (ADF) or one without.
ADF Scanning:
1. If you are using the
FineReader interface, select the Use ADF option in
the
Scanner Settings dialog (menu Tools>Scanner Settings) and then
select
File>Scan Multiple Images to start scanning multiple images.
2. If you are using the
TWAINSource interface, select the Use ADF option
in the
TWAINdialog of your scanner (keep in mind that this option may
be named differently depending on the scanner model used; consult your
scanner documentation for the exact procedure) and then select
File>Scan
Multiple Images
to start scanning.
33
Chapter 4. Acquiring the Image
Page 34
NonADF Scanning:
1. If you are using the
FineReader interface
z Select the Scan Multiple Images item in the File menu.
If you are using a flatbed scanner without an ADF, to increase productivity
try using one of the following two methods:
z Set a pause value i.e. the time that is to elapse between the scanning of
one page and the next. Select the
Pause between pages option and
then set the pause value (in seconds) in the
Scanner Settings dialog
(
Tools>Scanner Settings menu). As a result, the scanner won’t begin
scanning the next page until the specified number of seconds has
elapsed, thus allowing you sufficient time to place the next page onto
the scanner. After the pause, scanning continues automatically.
z Select the
Stop between pages option in the Scanner Settings dia
log (
Tools>Scanner Settings menu). As a result each time scanning
of a page is complete, a dialog asking you if you wish to continue scan
ning will appear. Click the
Ye s button to continue scanning or No to
finish scanning.
When you have finished scanning your pages, select the
Stop scanning
item in the File menu.
2. If you are using the
TWAINSource interface
z Select the Scan Multiple Images item in the File menu. The TWAIN
dialog of your scanner will open. Click the
Scan (Final, or other) but
ton to start scanning.
Scan your page, insert another page into your scanner and click the
Scan
button in the TWAINdialog of your scanner to continue scanning.
When you have finished scanning your pages, click the
Close or other scan
nerspecific button in the
TWAINdialog of your scanner.
Tip
: To have greater control over the quality of your scanned images, select the Open
image during scanning
option on the Scanning tab (Tools>Options). As a result, each
scanned page will be opened in the
Image window immediately after it has been scanned.
If you believe the image has been scanned incorrectly, halt the scanning process (click on
Stop Scanning in the File menu) and rescan the image.
34
ABBYY FineReader 6.0 User’s Guide
Page 35
Opening images
Even if you don’t have a scanner, you can still recognize image files (see the list of supported
image formats under “Supported Image Formats").
To open an image:
z Click on the arrow to the right of the 1Scan button and select the Open
Image item in the local menu. The appearance of the 1Scan button icon
will change – the Scan caption will be replaced with the Open caption.
z Select the Open image item in the File menu.
z In Windows Explorer: rightclick the image file you wish to open and select
the Open with FineReader item in the local menu. If FineReader is already
running, the image will be added to the current batch. Otherwise, before the
image is added, FineReader will be launched and the most recently used
batch opened.
Select one or several images in the
Open dialog. The selected images will be displayed in the
Batch window, and the last selected image displayed in the Image and Zoom windows. All
selected images are copied into the batch folder. See “General Information on Working with
Batches” section for more information on batch organization and the way in which pages
are displayed within batches.
Tip: If you want the opened images to be recognized right away, select
Open&Read
mode:
1. Select the
Open&Read item in the Process menu or just press
CTRL+SHIFT+D. The Open dialog will open.
2. Select the images for recognition in the
Open dialog.
Scanning dual pages
When scanning a book, although it is easier to scan both the left and right pages (i.e. a so
called ‘dual page’) at the same time, recognition quality is higher if, after scanning, the page
is split into two, with each page corresponding to a single book page. Recognition and lay
out analysis are then performed separately for each page, along with deskewing if required.
To split a dual page:
z Select the Split Dual Pages option on the Scan/Open Image tab
(
Tools>Options menu) before scanning.
Consequently, each dual page will be split into two batch pages. See “General Information
on Working with Batches” section for more information on batches.
35
Chapter 4. Acquiring the Image
Page 36
Note: If a dual page has been split incorrectly, clear the Split dual pages checkbox, scan
the dual page again, or readd the respective image to the batch and try to split the image
manually using the
Split Image dialog (Image>Split Image). (ABBYY FineReader 6.0
Corporate Edition only)
Adding business cards images to a batch
When inputting business cards, it makes sense to input as many as you can fit onto your
scanner. Recognition quality will be better (particularly if deskewing is carried out) if each
business card is recognized as a separate page. For this purpose, the application features
both automatic and manual business card image splitting tools. Note that the business cards
must be arranged in a particular order (for more information see under “Working with
Business Cards” of
ABBYY FineReader Help).
To split the image:
1. Select the image of your choice in the Batch window.
2. Select the
Split image item in the Image menu. The Split image dialog
will open.
3. Click the
Split business cards button.
Note: 1. The split page itself will be removed from the batch, and its place taken by the
split part images. For more information, see “General Information on Working
with Batches” in
ABBYY FineReader Help.
2. If the image has been split incorrectly, try splitting the image manually using
the
Add vertical separator/Add horizontal separator button.
3. To delete all separators, click the
Remove all separators button.
4. To move a separator, switch to
Select separator mode (click the but
ton) and move the separator.
5. To delete a separator, switch to
Select separator mode (click the but
ton) and move the separator outside the image.

1. Despeckle image
The recognized image may have a large amount of “dust” present on it, i.e. a large number of
excess dots. The dots arise in the case of documents of mediumtolow print quality, and
dots located close to character outlines may have an adverse effect on recognition quality.
To decrease the number of dots:
z Select the Despeckle image item in the Image menu.
To despeckle a particular block:
z Select the Despeckle block item in the Image menu.
Note: If the original document is very faint or set in a very light font, despeckling the image
may cause periods, commas, and very thin character parts to disappear, decreasing recognition
quality.
If you scan or open “dusty” images, select the Despeckle image item in the Image
Preprocessing
group on the Scan/Open Image tab (Tools>Options menu) to have
images despeckled before the application adds them to the batch.
2. Invert image
Some scanners invert images (turning black into white and vice versa) during scanning.
You may wish to apply the
Invert Image option to ensure that documents have a uniform
or standard appearance, e.g. a black font against a white background. To do this:
z Select the
Invert Image item in the Image menu.
Note: If you scan or open inverted images, select the Invert image item in the Image
Preprocessing
group on the Scan/Open Image tab (Tools>Options menu) before
adding these images to the batch.
3. Rotate or Flip image
Recognition quality depends greatly on an image having a standard orientation (the text should
be read from top to bottom and all lines should be horizontal). By default FineReader automati
cally detects page orientation during the recognition stage. If FineReader detects page orientation
incorrectly, clear the
Detect image orientation (during recognition) item on the
Scan/Open Image tab and rotate the image manually so that it has a standard orientation:
z Click the button or select the
Rotate Clockwise item in the Image
menu to rotate the image 90° clockwise.
z Click the button or select the
Rotate CounterClockwise item in the
Image menu to rotate the image 90° counterclockwise.
z Select the
Rotate Upside Down item in the Image menu to rotate the
image 180°.

Page numbering
Each scanned page is given a number. The number given by default is the number of the last
batch page plus one.
You can also set page numbers manually. You might wish to do this, if, for example, you
wish to retain the original page numbers or scan pages according to page number:
z Select the
Ask for page number before adding page to the batch
item on the Scan/Open Image tab (Tools>Options menu).
If you are scanning a large number of doublesided pages according to page number:
1. Select the

Page Layout Analysis
FineReader must know which image areas it needs to recognize
before starting the recognition process. Page layout analysis pro
vides it with this information by identifying text blocks, picture
blocks, table blocks, and barcode blocks (note: the latter are only
available in the Corporate Edition).
In this chapter you will learn more about the following: when
manual page analysis may be needed, what block types are avail
able, how blocks drawn using the automatic layout analysis pro
cedure can be edited, and also how the layout analysis process
can be made easier by using block templates.

General information on page layout analysis
Page layout analysis can be carried out both automatically and manually. In most cases,
FineReader manages the complex task of page layout analysis by itself. Start automatic analysis by
clicking on the
2Read button. Recognition and layout analysis are performed simultaneously.
Note: A standalone page layout analysis procedure is also available (Process>Analyze
Layout
menu). You may run this standalone procedure if needed, but note that here page
layout analysis quality may be inferior, as the coupled layout analysis/recognition procedure
uses additional information acquired during recognition to aid layout analysis.
You may wish to draw blocks manually if:
1. Only part of a page is to be recognized;
2. Automatic layout analysis has resulted in blocks being drawn incorrectly.
Tip: z In some cases automatic layout analysis quality may be improved by altering
the page layout analysis options. To view the current layout analysis options:
Recognition tab, Tools>Options menu.
z If the application has drawn some blocks incorrectly, it is often faster to edit
the incorrect blocks using the block editing tools than to delete the blocks
and draw them manually again.
Block types
Blocks are image areas enclosed in frames. They tell the system which image areas are to be
recognized and in what order. The blocks also influence the way in which the original page
layout is retained. Different types of blocks have differently colored frames. Block frame col
ors can be changed on the
View tab of the Options dialog (Tools>Options menu) in the
Appearance group. Select the required block type in the Item field and the color you want
in the
Color field.
The following block types are available:
Recognition Area – this block type is used for automatic recognition and analysis. After
you click the
2Read button, all blocks of this type will be automatically analyzed and rec
ognized.
Text – this block type is used for text image areas and should only contain text formatted
in one column. If there are pictures inside the text, draw separate blocks around them.
Table – this block type is used for table image areas or for areas of text structured in a
table. When the application reads blocks of this type, it draws vertical and horizontal sepa
42
ABBYY FineReader 6.0 User’s Guide
Page 43
rators inside the block to form a table. This block is represented as a table in the output
text. You can draw and edit tables manually.
Picture – this block type is used for image areas containing pictures. A block of this type
may enclose an actual picture or any other object (e.g. a section of text) you wish displayed
as a picture in the recognized text.
Barcode (Corporate Edition only) – this block type is used for barcode image areas. If
your document contains a barcode, and you do not want it to be displayed as a picture but
as a series of letters and numbers in the recognized text instead, draw a separate block for
the barcode and set the block type to barcode.
Note: It is possible to have barcode analysis and recognition carried out automatically, but
this option is not set by default. To enable this option, select the
Look for barcodes item on
the
Recognition tab (Tools>Options menu).
Automatic page layout analysis options
As part of the automatic page layout analysis procedure the following types of blocks are
drawn: text blocks, table blocks, picture blocks, and barcode blocks (note: the latter are only
available in the
Corporate Edition version).
To start automatic layout analysis (and text recognition) click the
2Read button. Before
clicking this button, however, select the main layout analysis options: document type and
table analysis options.
Document type
In most cases text layout is determined automatically. Automatic detection is performed if
the
Autodetect layout value on the Recognition tab in the Document Type group
(
Tools>Options menu) is set. Note that the value is set by default.
To select the document type manually:
z Select the desired type in the Document type group on the Recognition
tab in the Options dialog (Tools>Options menu).
Document types available:
Autodetect layout – (set by default) Text layout is determined automatically. Recognition
of all text types, including multicolumn texts, and texts containing tables and pictures, is
performed automatically.
43
Chapter 5. Page Layout Analysis
Page 44
Single column – The text is formatted into one column. Use this option if automatic page
layout analysis incorrectly determines the text type as multicolumn.
Plain text formatted with spaces – The text is formatted into one column and set in a
monospaced font that is uniform in size throughout. In the recognized text left indents are
represented by spaces, each line is made into a separate paragraph, and original paragraphs
are separated by means of empty lines. Useful, for example, when recognizing C++ code
printouts or old computer printouts.
Table analysis options
In most cases the application divides tables into rows and columns automatically. If addi
tional tuning of table options is required, open the
Recognition tab (Tools>Options>
Recognition
) and in the Tables group select the necessary item. Change these options if:
z automatic page layout analysis has drawn table rows and columns incor
rectly;
z the document contains a large number of simple tables of the same type (i.e.
there are no merged cells or there is always only one line of text per cell).
1. Use the One line of text per cell option if your table has no (or only a few)
black separators and there is only one line of text per cell. For example:
– this table has only one line of text per cell
– this table has more than one line of
text per cell
2. Use the
No merged cells in table option if your table has no merged
cells. For example:
– the Temperature cell is a merged cell

Note: Do not select One line of text per cell and/or No merged cells in table options if
there are tables with differing structures in your text. Selecting these options may result in
errors being made during layout analysis and have an adverse effect on recognition quality.
Drawing and editing blocks manually
To create a new block:
1. Select one of the following tools:
– to draw a recognition area;
– to draw a text block;
– to draw a picture block;
– to draw a table block.
2. Position the mouse at the point where you want a corner of your block to
be. Hold down the left mouse button and drag the mouse pointer to the
point where you want the opposite block corner to be.
3. Release the mouse button.
A frame will enclose the image area selected.

z Rightclick the block and select the
Block Type item followed by the corre
sponding block type in the local menu.
Modifying blocks
To move the block borders:
1. Click the block border and hold down the left mouse button. The mouse
pointer will become a twoheaded arrow.
2. Drag the pointer in the direction you need.
3. Release the mouse button.
Note: If you click a block corner, you can move both the horizontal and vertical borders of
the block at the same time.
To add a rectangular block part:
1. Select the tool.
2. Click the block you wish to add a part to. Press and hold down the left
mouse button then drag the mouse pointer diagonally. Select the image area
you wish added to the block and release the button. The rectangle drawn
will be added to the block.
3. If necessary, move the block border.
To cut a rectangular block part:
1. Select the tool.
2. Click the block you wish to cut a part from. Press and hold down the left
mouse button then drag the mouse pointer diagonally. Select the image area
you want cut and release the button. The selected rectangle will be cut from
the block.
3. If necessary, move the block border.
Note: 1. You can alter block borders by adding new nodes (splitting points) to them.
Then use the mouse to move split border segments in any direction you
desire. To add a new node, press
SHIFT then move the mouse pointer to the
point where you wish a new node to be created (the pointer will become a
cross) and click on the border. A new node will be created.
2. FineReader imposes certain requirements on block form. These require
ments exist as text lines within blocks must be unbroken if recognition is
to be successful. To ensure that these requirements are met, FineReader
automatically corrects block borders when parts are added or cut. For
example, if you cut a part off the top or bottom of a block, a whole block
corner will automatically be cut. Similarly, if you try to cut off a part
46
ABBYY FineReader 6.0 User’s Guide
Page 47
between the two upper or lower corners, the application will cut the right
block corner (upper or lower) regardless. It will also forbid certain opera
tions if they involve moving the segments forming the block borders.
To select a block or a group of blocks:
z Select the tool and click on the desired block or press the left mouse
button and draw a rectangle around all the blocks you wish to select.
Note: You can select one or more blocks using the usual block drawing tools. To select sev
eral blocks at once hold down
SHIFT or CTRL with one of the tools activated: , , or
and drag the arrow over the blocks you want to select. To invert the selection (i.e. to select
an unselected block or vice versa), hold down the
CTRL key with one of the tools activated:
, , or and drag the arrow over the desired blocks.
To move blocks:
z Hold down ALT with one of the tools activated: , , , or and
move the blocks.
To renumber blocks:
1. Select the tool.
2. Click the blocks in the order of your choice. The contents of blocks will be
displayed in the output text in the same order.
Note: If you renumber blocks on a previously recognized image, the recognized text in the
draft mode of the
Text window will be rearranged to reflect the new numbering.
To delete a block:
z Select the tool and click the block you wish to delete, or
z Select the blocks you wish to delete and press
DEL.
Note: If you delete a previously recognized block, its text in the Text window will be delet
ed too.
To delete all image blocks:
z Select the Delete blocks and text item in the Batch menu.
Note: If you delete blocks on an image that has already been recognized, the recognized
text in the
Text window will also be deleted
47
Chapter 5. Page Layout Analysis
Page 48
Manual table layout analysis
Tip: If automatic table layout analysis has resulted in table rows and columns being drawn
incorrectly, try editing the automatic analysis results instead of deleting all the blocks and
drawing them manually again. Almost invariably this proves less time consuming.
Editing a table manually:
Use the following
Image toolbar tools to edit a table:
– Add vertical separator
– Add horizontal separator
– Remove separator
If the table cell only contains a picture, select the
Treat cell as picture item in
the
Block Properties dialog (View>Properties menu). If the table cell con
tains both text and pictures, draw a separate picture block (or blocks) inside the
cell.
To merge table cells or rows:
z Select the Merge Table Cells or Merge Table Rows item in the Edit
menu.
Note: You can split previously merged cells using the Split Table Cells com
mand (
Edit menu). The Merge Table Rows option does not affect the division
of the table into columns.
Note: To avoid drawing horizontal and vertical separators manually, draw a separate table
block, then rightclick it and select the
Analyze Table Structure item in the local menu.
The system will then draw all the separators it considers necessary. Should the system draw
any separators incorrectly, you can edit the table manually.
Using block templates
If you are processing a large number of documents with an identical layout (e.g. forms or
questionnaires), analyzing each page's layout separately will prove extremely time consum
ing. To save time you can create a block template, i.e. a standard set of blocks of a particular
type that corresponds to the layout of your pages, and then apply the template to all pages
you wish recognized that have the same layout.
Note: Documents should always be scanned using their respective template(s) and using the
same resolution as that used to create the template(s).
48
ABBYY FineReader 6.0 User’s Guide
Page 49
To create a block template:
1. Open an image and draw the blocks automatically or manually.
2. Select the
Save Blocks item in the Image menu. The Save Blocks as dia
log will open. Type a file name for the block template in the dialog.
To load a block template:
1. Click the Batch window and select the pages you wish to apply the block
template to.
2. Select the
Load Blocks item in the Image menu. The Open Blocks dialog
will open.
3. Select the relevant block template file in the dialog.
4. Click the appropriate
Apply to item in the group. The All pages item
applies the block template to all batch pages, the
Selected pages item
applies the block template to selected pages only.

Recognition
The aim of OCR is to read text from a source image and retain
the source page layout. Before this can be done, however, the
main recognition parameters – recognition language, source
text print type, and document type need to be set. This chapter
deals with these parameters and other important recognition
issues, including the use of different recognition settings, etc.

General information on recognition
Note: Always ensure that the following options have been correctly set before you start
recognition: recognition language, source text print type, and document type.
You may: 1. Recognize a block or several blocks drawn on an image.
2. Recognize an open page or all pages selected in the
Batch window.
3. Recognize all unrecognized batch pages.
4. Recognize all pages in background mode. Background mode allows you to
edit and recognize pages at the same time.
5. Recognize pages in training mode. Training mode is used for recognizing
texts set in decorative fonts or for processing large volumes (more than a
hundred pages) of documents of inferior print quality.
6. Recognize the same batch on several workstations.
To start recognition:
z Either click the 2Read button on the WizardBar toolbar, or
z Select the item of your choice in the
Process menu:
Read – to recognize the open page or all the pages selected in the Batch
window;
Read All Pages – to recognize all unrecognized batch pages;
Read Block – to recognize a block or several blocks drawn on the image;
Start Background Recognition – to start recognition in background
mode.
By default, the
2Read button recognizes the open image. To change button
mode, click the arrow to the right of the button and select the mode of your
choice in the local menu.
Note: When you perform OCR on a page that has already been recognized, recognition will
only be carried out on new or modified blocks.
Recognition language
FineReader recognizes both mono and multilingual (e.g. EnglishFrench) documents.
To set the text recognition language, select it in the dropdown list on the
Standard toolbar.
To recognize a multilingual document:
1. Select the Select multiple languages item in the language list on the
Standard toolbar. The Recognition language dialog will open.
2. Select the languages of your choice in the
Recognition language dialog.
52
ABBYY FineReader 6.0 User’s Guide
Page 53
Note:
1. If you find that you often use a certain language combi
nation, you can create a new language group that
includes the languages you most often use.
2. Increasing the number of the recognition languages used
simultaneously may have an adverse effect on recognition
quality. A reasonable number of languages to use simulta
neously is 2–3.
3. Before recognizing a document, ensure that the fonts
selected on the
Formatting tab support all the charac
ters contained in the recognition language(s) chosen,
otherwise the recognized text will be displayed incor
rectly (“?” or “ ” symbols will appear instead of letters).
See under “Fonts for Recognition Languages that may be
Displayed in Text Editor Incorrectly” in
ABBYY
FineReader Help
for more information.
You may find that your chosen recognition language is not listed. This can be because of one
of the following reasons :
1. The language is not supported by FineReader. See the complete list of recog
nition languages under “Supported Languages” in
ABBYY FineReader
Help
.
2. The language has not been included in the recognition language list dis
played on the
Recognition toolbar. To add a language, select the Choose
more languages
item in the language list on the Standard toolbar. The
Recognition language dialog will open. Select the language of your choice
in the dialog.
3. The language was disabled during custom installation.
Note: Always ensure that you use the same folder as the one that contains FineReader.
To show/hide a language in the dropdown list on the toolbar:
z Select the language of your choice in the Language Editor dialog
(
Tools>Language Editor) and then check or uncheck the Show this
language in the dropdown list on the toolbar
item.
Tip: It is even possible to set a recognition language for an individual block. To do this,
rightclick the block concerned and select the
Properties item in the local menu. The
Properties dialog will open. Select the Block tab in the dialog and then select the block
recognition language in the
Languages field on the tab.

Chapter 6. Recognition
Page 54
Source text print type
As a rule source text print type is determined automatically. To ensure that this is the case,
select
Autodetect in the Print Type group (Tools>Options menu, Recognition tab).
When recognizing draft mode dot matrix printouts or typewritten texts, recognition quality
can sometimes be increased by selecting another
print type:
z Select the
Typewriter item if you wish to recognize typewritten texts
z Select the
Dot Matrix Printer item if you wish to recognize dot matrix
printouts.
An example of draft mode dot matrix text. Character lines are
made up of individual dots.
An example of typewritten text. All letters are of equal width
(compare, for example, “w” and “a").
To change print type:
z Select the print type of your choice on the Recognition tab in the
Options dialog (Tools>Options menu).
Note: Once you have completed recognition of typewritten texts or dot matrix printouts,
remember to reenable the
Autodetect item to recognize normal texts once again.
Other recognition options
Show image during recognition
When processing large numbers of pages, recognition is invariably faster if the processed
image is not displayed onscreen. To run recognition without displaying the image:
z Clear the
Show image during recognition item on the General tab
(
Tools>Options menu).
Text direction
If the application recognizes blocks containing vertical text incorrectly (a text block or a
table cell):
z rightclick the block containing the vertical text and select the
Properties
item in the local menu. The Block properties dialog will open. Select the
relevant item in the
Text direction list in the dialog and rerecognize the
image.
54
ABBYY FineReader 6.0 User’s Guide
Page 55
Inverted or flipped block
If the application recognizes blocks containing inverted or flipped text incorrectly (a text
block, a table cell, or a whole table):
z Rightclick the block concerned and select the
Properties item in the local
menu. The Block properties dialog will open. Select the
Inverted or
Flipped item in the dialog and rerecognize the image.
Background recognition
If you wish to edit previously recognized pages and run recognition at the same time, you
may find background recognition mode useful. To start background recognition:
z Select the
Start Background Recognition item in the Process menu.
The sign will appear in the status line at the bottom of FineReader’s
main window. If
Details view mode is active in the Batch window (to acti
vate
Details view mode, rightclick on the Batch window and select
View>Details in the local menu), the page currently being recognized will
have the icon displayed in the
Opened by column.
When background recognition mode is activated, recognition will resume automatically if
an unrecognized page is added to the batch.
Note: Running background mode in the case of multiprocessor systems leads to an increase
in recognition speed if the batch being processed contains a large number of pages.
To stop Background Recognition:
z Select the Stop Background Recognition item in the Process menu.
Note: Background recognition mode uses recognition options active at the moment it has
been started.
Recognition with training
As previously stated, FineReader can read texts set in practically any font regardless of print
quality. Consequently, no prior training is normally required before recognition can take
place. FineReader, nevertheless, features a number of user pattern training tools.
Train User Pattern mode may come in useful when:
1. recognizing texts set in decorative fonts;
2. recognizing texts containing unusual characters (e.g. mathematical symbols);
55
Chapter 6. Recognition
Page 56
3. recognizing large volumes (more than a hundred pages) of texts of low print
quality.
Tip: Use
Train User Pattern mode only if one of the above applies. In other cases
you may obtain a slight increase in recognition quality, but the time and effort involved will
probably outweigh the benefit received.
Pattern training works as follows. One or two pages are recognized in training mode, and,
subsequently, a pattern created. FineReader then uses this pattern to aid recognition of the
remaining text.
Sometimes two or even three characters may get “glued” together, and FineReader may be
unable to enclose each character in an individual frame to separate them. If this proves to
be the case (i.e. you cannot move the frame so that it contains only one whole character
and no other character parts), you can train FineReader to recognize the whole inseparable
character combinations. Examples of character combinations frequently found glued togeth
er include ff, fi, and fl. Such combinations are referred to as ligatures.
Note: 1. A pattern is only useful in the case of documents that have the same font, font
size, and resolution as the document used to create the user pattern.
2. Each pattern is created for a particular batch. Consequently, if a batch is
deleted, its user pattern is also deleted. Patterns can, however, be copied into
other batches. To transfer a user pattern to another batch, simply save the
batch options in a batch template format file.
3. If you switch to recognizing texts set in a different font, always disable any
user patterns – choose the
Do not use user pattern item on the
Recognition tab, menu Tools>Options.
To train a user pattern:
1. Start Train user pattern mode – click the Train user pattern radio but
ton on the
Recognition tab, Tools>Options menu, in the Training
group. The default pattern name ("Default") will be displayed in the status
line.
2. Click the
2Read button.
3. Train your pattern – recognize one or more pages in
Train user pattern
mode. Trained characters are saved in the default pattern. Once you have
completed training the pattern, FineReader will save the pattern
(
Default.pat) in the current batch folder.
4. Edit your pattern.
5. Deactivate training mode (click the
Use user pattern button on the
Recognition tab).
6. Recognize the rest of the text – click the
2Read button.
56
ABBYY FineReader 6.0 User’s Guide
Page 57
Note: 1. To create several patterns for the same batch, use the Pattern Editor dialog
(click the
Pattern Editor button on the Recognition tab or select the
Tools>Pattern Editor menu item). Create a new pattern (click the New
button in the dialog) and select it (click the Set Active button). Working
with a created pattern is no different to working with a default pattern (see
steps 15). Keep in mind, however, that only one pattern may be active at any
one time.
2. If you’ve created several patterns for the same batch, the active one will be
the pattern that was last created. The active pattern name is displayed in the
status bar. To activate another pattern, select the pattern of your choice in
the pattern list in the
Pattern Editor dialog (Tools>Pattern Editor
menu) and click the Set Active button. Then click the Use user pattern
button on the Recognition tab, Tools>Options menu, in the Training
group.
3. If the
Use builtin patterns option is set, FineReader will read all texts
using its builtin patterns and stop only at uncertain characters. If you are
training the system to read decorative and/or nonstandard fonts (for exam
ple, Tibetan) the use of inbuilt patterns may result in characters being read
incorrectly. If the latter occurs, disable the use of inbuiltpatterns (clear the
Use builtin patterns checkbox on the Recognition tab) and train the
system to recognize each unknown character it is likely to encounter.
How to train a user pattern

Chapter 6. Recognition
Page 58
Training to recognize a character:
The frame in the top dialog window should enclose
a single character, and this character
must be fully enclosed by the frame. If the frame encloses only part of a character or
more than one character, click the frame borders and move them so that the abovestated
requirements are met. The and buttons move the frame border as well (and are
useful for training italic symbols – see below). Once you have positioned the frame correct
ly, type in the character and click the
Train button.
Note: 1. You may only train the system to read characters included in the alphabet.
If you wish to train FineReader to read characters that cannot be entered from
the keyboard, use a combination of two characters to denote these nonexis
tent characters or copy the required character from the
Character Table
(click the button in the Pattern Training dialog to open the Character
Table
).
2. If you wish to train the system to retain character formatting, select the cor
responding
Italic or Bold item in the Pattern Training dialog before
clicking the
Train button.
3. Make sure that only uppercase/lowercase characters are entered when train
ing uppercase/lowercase character images respectively.
If you make a mistake during training, click the Back button to return the frame to its pre
vious position. The last “imagecharacter” pair to be entered will automatically be removed
from the pattern. Note that this “undo” function is limited to the last word trained.
Training to recognize ligatures
A ligature is a combination of two or three “glued” characters, for example, fi, fl, ffi, etc.
These characters are difficult to separate because they are “glued” as part of the printing
process. In fact, better results can be obtained by treating them as “single” compound char
acters.
Training ligatures is no different to training separate characters:
1. Type in the desired character combination and click the
Train button.
2. The frame in the top dialog window should enclose the entire ligature. You
can move the frame border using the mouse or by clicking the and
buttons.
Each pattern may contain up to 1000 new characters. However, avoid creating too many lig
atures, as it may have an adverse effect on recognition quality.
Always take the following into account when training FineReader:
1. FineReader does not differentiate between certain characters that are nor
mally considered different. For example, the straight (
|
), right (/ ) and left (\ )
58
ABBYY FineReader 6.0 User’s Guide
Page 59
apostrophes are treated as one character – the straight apostrophe. Thus,
you will never see right and left apostrophes in recognized text, even if you
attempt to train FineReader into recognizing them.
2. The way in which certain characters are recognized depends on their envi
ronment.
How to edit a user pattern
You may wish to edit a new pattern before you start using it, as an incorrectly trained pat
tern will result in recognition quality being adversely affected.
The pattern should only contain whole characters or ligatures. Characters with cut edges
and incorrectly labeled characters should be removed from the pattern.
To edit a user pattern:
1. Select the Pattern Editor item in the Tools menu. The Pattern Editor
dialog will open.
2. Select the relevant pattern and click the
Edit button in the dialog. The User
Pattern
dialog will open.
3. Select a character and click the
Properties button to edit the character
caption and set the correct typeface: italic, bold, subscript or superscript.
Click on the
Delete button to remove any incorrectly trained characters
from the batch.
User languages and language groups
In addition to the builtin languages and language groups, you may also create new lan
guages and language groups (made up of languages supported by FineReader) and use them
for recognition.
You may want to create a new language if you need:
1. To use a user dictionary.
z For example, you want to recognize an English text containing many
abbreviations. You therefore create an abbreviation dictionary, create a
new language and linkup the dictionary to the language. You then cre
ate a new language group consisting of English (using the application
dictionary) and your new language (containing the abbreviations dic
tionary), and use this language group to recognize your texts.
2. To recognize documents of a specialized nature, for example:
z supermarket productline lists containing only product codes. Product
codes are usually made up of numbers and a few letters. Consequently,
59
Chapter 6. Recognition
Page 60
you can create a new language consisting only of the numbers and let
ters used in the codes to be applied when recognizing documents of this
type.
z documents set in capitals only. Recognition quality is increased if you
create a language in which all lowercase letters are prohibited.
You should create a language group if you use a particular language combination often.
To create a new language or language group open the
Language Editor dialog (Tools
menu, Language Editor item).
How to create a new language
To create a new recognition language:
1. Select the Language Editor item in the Tools menu.
2. Click the
New button and in the resulting dialog select the Create a Copy
of the Language
button, then select your preferred source language.
3. The
Simple Language Properties dialog will open.
Set the following language parameters for the new language (all parameters are
entered in the Simple Language Properties dialog):
1. The new language name.
2. The basic alphabet to be used by the language. This parameter is set in the
Alphabet field. If necessary, edit the alphabet by clicking the button.
3. The dictionary to be used by the application (for both recognition and spell
check purposes). You may choose one of the following:
z
None (no dictionary to be used)
60
ABBYY FineReader 6.0 User’s Guide
Page 61
z Builtin (the dictionary supplied with FineReader)
z
User dictionary
To add words to the dictionary or to use an existing user dictionary or
text file in Windows (ANSI) or Unicode encoding (the only requirement
is that words be separated by spaces or other nonalphabetic characters)
click the
Edit Dictionary button.
Note: The spellchecker will consider user dictionary words to be correct
if they are found in the text in one of the following capitalizations: dic
tionary set capitalization; lowercase only; uppercase only; first letter – cap
ital, remaining letters small. Examples include:
z Regular expression (used to specify the grammatical rules of the
new language; see the Regular Expressions section for details).
Note: 1. Click on the Advanced button in the Simple Language Properties dialog
to set advanced properties for the new language e.g. characters to be ignored,
prohibited characters, etc.
2. By default, all new user languages are saved into the batch folder. Note
that ABBYY FineReader Corporate Edition allows you to specify the fold
er to which the language should be saved. For more information on
group work with user languages and dictionaries, see under “Group work
with the same user languages and user dictionaries".
How to create a new language group
If you often recognize texts written in a certain language combination, say, English
German, you can create a language group combining these languages. The created group
will be displayed in the language list on the
SSttaannddaarrdd
toolbar.
Note: You can specify the recognition languages to be used in the language list on the
Standard toolbar. To do this, select the Select multiple languages item in the list. The
Recognition Language dialog will open. Select the languages you need in the dialog.

Checking and Editing Text
Once recognition is over, you will see the recognized text dis
played in the
Text window. The Text window is ABBYY
FineReader’s builtin editor, used to check recognition results
and edit any recognized text.
The FineReader text editor has two distinctive features:
1. A builtin spell check system (see the list of languages with
spell check support under “Supported Languages” in
ABBYY
FineReader Help
).
2. A convenient visual aid: the source image of the text line
being edited is displayed in the
Zoom window.
The builtin spell check system features:
1. Tools for finding uncertain words (words containing uncertain
characters).
2. Tools for finding misspelt words.
3. Tools for adding unknown words to the FineReader dictionary.
Adding words to the dictionary improves recognition quality.

Uncertainly recognized characters and words not found in the dictionary are highlighted in
different colors. By default, light blue is used for uncertain characters and pink for words
not found in the dictionary. To change the colors used:
z Select the
Uncertain Character (or Not in Dictionary word) item fol
lowed by the color of your choice in the
Color item on the View tab
(
Tools>Options menu) in the Appearance group.
To check recognition results:
1. Click the 3Check Spelling button on the WizardBar toolbar (or select
the
Check Spelling item in the Tools menu).
2. The
Check Spelling dialog will open.
3. There are three windows in the
Check Spelling dialog. The top window is
similar to the FineReader
Zoom window and displays the original image of
the word. The middle window displays the word itself, and the line above
the name of the error type. The
Suggestions window at the bottom pro
vides you with replacement suggestions (if any exist). Note that suggestions
are based on the dictionary selected in the
Dictionary language drop
down list; any language may be chosen from this list.
Note: You can enlarge the Check Spelling dialog to make it easier to
check and edit text. Simply click the dialog border; the mouse pointer will
become a doubleheaded arrow. Drag the border to make the dialog larger or
smaller.
64
ABBYY FineReader 6.0 User’s Guide

4. If words have been misspelt, you can do one of the following:
z Click the
Ignore button to leave the word unchanged.
z Click the
Ignore All button to leave all such words in the text
unchanged.
Note: When you click the Ignore or Ignore All button, the “uncer
tain” flag is removed from the word i.e. the system assumes that the word
no longer contains any unrecognized or uncertain characters and no
longer needs to be highlighted. As a result, when you export such words in
PDF format and select the
Replace uncertain words with images
mode, the words for which the “uncertain” flag has been removed will not
be replaced with images.
z Select a replacement suggestion and then click the Replace or Replace
All
button to replace the current word or all such words in the text. If
no correct suggestion has been made for the word in the
Suggestions
window, you can enter one yourself in the middle window. (Important:
when you switch to edit mode, certain buttons may change function and
adopt new captions). Click the
Confirm (Confirm All) button to
change the current word (or all such words) in the text and move to the
next uncertainly recognized word.
z Click
Add... to add a word to the dictionary. Once a word is added, the
application will consider all subsequent occurrences of this word in any
of its word forms to be correct.
z Click
Options... to set the spell check options.
z Click
Close to close the dialog window.
Moving between uncertain words
To check recognition results quickly, you can use the button and button to move to
the next or previous uncertain word respectively.
You can also use the
F4 (SHIFT+F4) hotkey to navigate between uncertain words.
Options for checking and editing text
These options are set on the Check Spelling tab (Tools>Options menu).

Error display level
The Error display level option allows you to select the degree to which errors are highlighted:
z
None – no recognition errors are highlighted.
z
Standard – unrecognized and uncertainly recognized characters are high
lighted.
z
Thorough – the same as Standard, however nondictionary words are also
highlighted.
Note: The number of errors displayed in the Text window will change if you reread a page
using a different error display level.
Stop at words with uncertain characters
The spell check stops each time it encounters words with uncertain characters.
Stop at words not found in the dictionary
The spell check stops each time it encounters nondictionary words. Note that a word may
well be contained in the dictionary, and has simply been read incorrectly.
Stop at compound words
The spell check stops at nondictionary words that can, however, be made up according to
available morphological models or from other dictionary words.
Ignore words with digits and other nonalphabetic characters
The spell check treats all words containing digits and other characters not included in the
recognition language as correct unless they also contain uncertain characters.
Correct spaces before and after punctuation marks
The spell check does not stop if it comes across incorrect spacings before or after punctua
tion marks, it simply corrects them automatically.
Adding and deleting words
to/from the user dictionary
Adding words to the user dictionary
Enlarging the dictionary is a good way of increasing recognition quality. During recognition,
FineReader checks all words it comes across for possible dictionary entries. Therefore it
66
ABBYY FineReader 6.0 User’s Guide
Page 67
makes sense to add new words that are likely to come up frequently (e.g. specialized terms,
abbreviations, names etc.) to the user dictionary.
A distinctive feature of FineReader’s spell check system is that a word is not only added to
the dictionary in its original form, its paradigm (i.e. the set of all of its forms) is also added.
This feature results in FineReader being able to recognize a word in all its forms once it has
been entered.
To add a word to the dictionary during spell check:
z Click the Add button in the Check Spelling dialog.
Set the following parameters in the
Primary Form dialog:
1.
Part of speech (Noun, Adjective, Verb, Uninflected).
2. If the word is to always begin with a capital letter, select the
Proper name
item. If you add an abbreviation, select the Abbreviation item.
3. The primary form of the word.
Click
OK. The Create Paradigm dialog will open. FineReader will ask you questions about
the word forms in order to be able to construct the paradigm of the word you wish to add.
Click
Ye s or No to answer these questions. If you make a mistake, click the Anew button to
have FineReader ask the question again. The constructed paradigm will be displayed in the
Paradigm dialog.
Note: 1. If you do not wish paradigms to be created for the words you add, and want
them to be entered uninflected instead, select the
Add without prompting
for word forms
option (English dictionary only) on the Check Spelling
tab (Tools>Options menu).
2. You may also add words when you view the list of added words. To do this,
select the
View Dictionaries item in the Tools menu. The Select
Language
dialog will open. Select the language of your choice in the Select
Language
dialog and click View. The dictionary with the list of the added
words will open. Add words by clicking on the
Add button.
3. Paradigms can only be constructed for words added in the following lan
guages: Armenian (Eastern, Western, Grabar), English, Italian, French,
German (Old and New spelling), Russian, Spanish, and Ukrainian.
If the word you wish to add is already present in the dictionary, a notice to this effect will be
issued. You may then wish to view its paradigm. If you think the existing paradigm is incor
rect (this is often the case with homonymous words, for example), construct another one
(click the
Add button in the Add Word dialog).

Editing text in ABBYY FineReader
Note: If the FineReader Text window does not display characters correctly (i.e. “?” or “ ”
can be seen in place of some or all of the letters), this means that your current font does not
support your recognition language alphabet in full. Select a font that supports your entire
recognition set (for example, Arial Unicode or Bitstream Cyberbit) on the
Formatting tab
(
Tools>Options menu) in the Fonts group, and recognize the document again. See under
“Fonts for Recognition Languages that may be Displayed in Text Editor Incorrectly” in
ABBYY
FineReader Help
.
After a page is read, its text is displayed in the Text window. When you send your text to an
external application, the text layout is retained according to the layout retention options
chosen. Set these options on the
Formatting tab (Tools>Options menu) and in the
dialogs of the respective formats.
Uncertainly recognized characters are highlighted. To cancel this feature, unselect the

FineReader editor features two document viewing modes: full mode (the full layout is dis
played) and draft mode.
In full mode blocks with recognized text, tables and pictures are displayed exactly as they
are to be found on the original image. The complete original layout, therefore, is retained:
columns, tables, pictures, and dropped capitals (oversized letters that take up several lines of
space in a paragraph). The block in which the pointer is currently located is the active
block. If the pointer is moved using the arrow keys, the order of navigation between blocks
is determined by their numbering on the original image. If the amount of text inside a par
ticular block becomes too large for the block concerned (e.g. following editing), parts of
other inactive blocks may become invisible. If this is the case, the borders of the block(s)
concerned will be displayed with red markers. When a block is active, its borders are
enlarged so as to display the entire block text.
The following text features are not displayed in draft mode: left indent; paragraph alignment
(all paragraphs are aligned to the left); text and background color. A samesize font (12pt by
default) is used throughout to display text in draft mode. Effects (bold, italic, underlined,
superscript and subscript) are all retained.
Switch between draft and full modes by clicking the (full mode) or (draft mode) but

z save the page image.
Click the
4Save button to export recognition results to the application
of your choice or save them to file. The icon's appearance will depend on
the currently active save mode. The
Save button will display the name of
the currently selected export application.
To save recognized text:
z Click the arrow to the right of the 4Save button and select the item of your

Retain pictures
If you choose this option, pictures will be saved together with recognized text. The option is
only available in the case of
RTF, DOC, and HTML formats.
Image resolution (RTF/DOC, PDF, and HTML formats)
Sometimes you may wish to reduce image resolution. For example, HTML files are normally
viewed using browsers, and highresolution files, due to their size, are usually unwelcome on
the Internet. To reduce image resolution (and, consequently, HTML file size) without lower
ing image quality, enter a lower resolution value in the
Reduce picture resolution to
field on the Formats>RTF/DOC (PDF, HTML) tab.
Note: If you enter a higher resolution value than the one originally entered in the Reduce
picture resolution to
field, this value will be ignored; the pictures will be saved using the
source resolution.
JPEG quality (saving in PDF and HTML)
When you save the text in PDF and HTML formats, the pictures are saved in JPEG format.
This format uses a socalled “quality loss” algorithm to compress the image, i.e. the com
pressing technology is based on averaging groups of pixels, so that a whole region is saved
as a single number rather than a large amount of different numbers for each pixel. The qual
ity of the image will be determined by the value specified in the
JPEG quality field
(
Tools>Formats, PDF and HTML tabs). A value in the range 1 – 100 may be specified (the
default value is 50 – the average value).
The higher the value you specify in this field, the higher the quality of the saved image. The
size of the image is also affected by this value: the higher the value, the larger the *.jpg file
that is created. To obtain the most favorable size/quality combination, save the image using
75
Chapter 8. Saving into External Applications and Formats
Page 76
different JPEG values, and open it in an image viewing application. The JPEG quality value
is set on the
Formats>PDF (HTML) tab.
Fonts to use (when saving in RTF, DOC, or HTML format)
By default the fonts specified on the
Formatting tab are used when saving in RTF, DOC, or
HTML format. You can, however, change the fonts that are used. Change fonts in the
Text
window or select other fonts on the Formatting tab in the Fonts group and reread the
document.
Save all batch pages or selected ones only
You may either save all batch pages or selected ones only. To save only certain pages, select
them before saving.
Recognized text saving modes (when saving several batch pages at
a time)
z
Create a separate file for each page – each batch page is saved as a
separate file. The batch page number is automatically added to the end of
each file name.
z
Name files as source images – use this option to save each page in a
separate file the name of which is to be the same as that of the original
image.
Note: 1. Pages that are not related to the original image (e.g. scanned
pages) will not be saved in this mode. A warning will be dis
played if such a page is encountered among those to be saved.
2. If a number of consecutive batch pages all contain the same
image as the original image or the images all have the same
name, the pages will be treated as a multipage TIFF and the
text saved into a single file. If a number of pages have identi
cal names but are not in consecutive order, the pages will be
treated as individual image files, and the text saved in differ
ent files, with an index appended to their file names: _1, _2,
etc.
z Create a new file at each blank page – the whole batch is treated as a
set of page groups, with each group ending with a blank page. Pages from
different groups are saved into different files with file names consisting of
the userspecified name and index number: 1, 2, 3 etc.
z
Create a single file for all pages – all (or all selected) batch pages are
saved as a single file.

Saving the recognized text in RTF and DOC formats
Layout retention modes are set on the Formatting tab in the Options dialog
(
Tools>Options menu).
Note: When you save text in RTF or DOC formats, the fonts used are those set on the
Formatting tab in the Options dialog (Tools>Options menu) or those set during text
editing in the
Text window.
Tip: If you prefer editing recognized text in Microsoft Word rather than in the FineReader
text window, you may still have uncertain characters highlighted. For this to be the case,
select the
With background color and/or the With text color item(s) on the RTF/DOC
tab in the Highlight uncertain characters group. The saved file will have all the uncer
tain characters highlighted in the color of your choice.
Saving recodnized text in PDF format
Document layout retention options:
1. Text and pictures only – only recognized text and pictures are retained.
2.
Image only – only the image is retained.
3.
Text over the page image – the entire image is saved as a picture. Text
areas are saved as text over the picture.
4.
Text under the page image – the entire image is saved as a picture, and
the recognized text placed underneath. This option is useful if you export
your text to document archives: the full page layout is retained and a full
text search is available if you save in this mode.
To set these options:
1. Select the Formats Settings item in the Tools menu. The Formats
Settings
dialog will open.
2. Set the options of your choice on the
PDF tab in the dialog.
Note: 1. A special Replace uncertain words with images option is available if you
use
Text and pictures only or Text over the page image mode. If you
select this option, all uncertain words will be replaced with their images. Set
this option on the
PDF tab in the Formats Settings dialog.
2. If you wish to edit recognized text before exporting it in PDF format, we
recommend you pay special attention to preserving the original line division
(i.e. avoid deleting existing lines and adding new ones), otherwise the result
ing PDF file may be displayed incorrectly (e.g. lines may overlap).
77
Chapter 8. Saving into External Applications and Formats
Page 78
3. When you save texts that use a nonLatin code page (e.g. Cyrillic, Greek,
Czech, etc.), ABBYY FineReader will save them using ParaType company
fonts (www.paratype.com/shop).
4. If, during PDF export, a message appears informing you that your text con
tains a number of nonstandard font characters, you must then select Type 1
working mode and corresponding Type 1 fonts. These fonts are supplied as
part of Adobe Type Manager or in the Windows 2000 postscript font
installer. For more information on Type 1 fonts, see “Using Type 1 fonts dur
ing export to PDF” in
ABBYY FineReader Help.
5. Before you can edit PDF files that contain nonLatin code page (e.g. Cyrillic,
Greek, Czech, etc.) in Adobe Acrobat, the text font must be changed to one
installed on your computer.
Saving recognized text in HTML format
Layout retention modes are set on the Formatting tab in the Options dialog
(
Tools>Options menu).
Note: When you save text in HTML format, the fonts used are either those set on the
Formatting tab in the Options dialog (Tools>Options menu) or those set during text
editing in the
Text window.
To retain pictures in an HTML file:
z Select the Keep pictures option on the Formatting tab in the Options
dialog (Tools>Options menu)
Note: Pictures are saved into separate *.jpg files. The resolution of the
images and their quality can be determined on the
HTML tab of the Formats
dialog (Tools>Formats).
HTML formats available:
1. Full (uses CSS and requires Internet Explorer 4.0 or later) – the
latest HTML format – HTML 4 – is used. HTML 4 supports all document lay
out retention types (the actual retention type used depends on the options
set on the
Formatting tab in the Retain layout group). The builtin style
sheet is used.
2.
Simple (compatible with all (Internet) browsers) – HTML 3 format
is used. The approximate document layout is retained i.e. the first line indent
is not retained but the approximate font size is (HTML 3 format supports
only a limited number of font sizes; FineReader will choose the HTML 3 for
mat font size that corresponds to the actual font size of your text). This
78
ABBYY FineReader 6.0 User’s Guide
Page 79
HTML format is supported by all browsers (Netscape Navigator, Internet
Explorer 3.0 and later).
3.
Auto (saves Full and Simple formats in a single file with autose
lection depending on browser type)
– both formats (Simple and Full)
are saved to the same file. The browser you use will determine the format
that is used.
To set the HTML format of your choice:
z Click the relevant button on the HTML tab in the Formats Settings dialog

Working with Batches
The batch is the main ABBYY FineReader data depository:
scanned images, recognized text and other data are all kept in
the batch. The majority of FineReader settings are batch settings:
scanning, recognition, saving options, etc. User patterns, user lan
guages and user language groups are also batch “property”. When
you create a new batch, you may use the default batch settings,
the settings of the current batch, or settings saved in an *.fbt file.

General information on working with batches
When FineReader starts for the first time, it opens the batch located in the FineReader fold
er. You can choose to work with this batch or create a new one. A batch may contain up to
9999 pages.
Tip: You may find it useful to save similartype pages (e.g. pages from the same book, writ
ten in the same language, or with a similar layout) in the same batch. By doing this you will
find your work much easier.
The
Batch window displays a list of the pages contained in the open batch. To view a page,
just click on its icon or doubleclick its page number. All files related to this batch page will
open in their respective windows, i.e. text file (if the page has been recognized) in the
Text
window, the image file in the Image window, etc.
There are two main ways of displaying pages in the Batch window:
Batch View Description
Thumbnails Batch pages are displayed as thumbnails, a thumbnail being a miniature
image of the original page. Additional icons appear on the thumbnails
as you process the images. These inform you of the actions that
have been performed on them, e.g. recognition, saving, etc.
Thumbnail images are particularly useful when searching for
a particular batch page. To open an image, just click on its thumbnail.
Details Here detailed information is displayed on each batch page in the
batch window, and page lists created according to any feature
specified. This is useful in the case of large batches, as the batch
window can accommodate a much greater number of pages in this
view than in
Thumbnail view. Doubleclick on a page to open it.
To choose the page view in the Batch window:
z Rightclick the Batch window and select the View>... item in the local
menu.
To customize the
Batch window, i.e. choose the features that are to be displayed, the way in
which pages are sorted, etc:
z Rightclick the
Batch window and select the Batch View>Customize
item in the local menu. A dialog will open. Select the options of your choice
on the
Thumbnails and Details tabs of the dialog.
82
ABBYY FineReader 6.0 User’s Guide

You may select several different pages, a number of consecutive pages, or all batch pages:
z To select a number of pages in a row, hold down the SHIFT key and
click the first and last page of the group you wish to select.
z
To select several pages, hold down the CTRL key and click the pages of
your choice.
z
To select all batch pages, activate the Batch window and choose the
Select All item in the Edit menu or press CTRL+A.
Creating a new batch
To create a new batch:
1. Select the New Batch item in the File menu. The Create New Batch dia
log will open.
2. Select or create a folder for the new batch in the
Create New Batch dia
log.
3. Select the
Batch Template field and choose one of the following options
depending on the settings you wish applied to the new batch:
Default set
tings
– to apply default settings, Current Batch – to apply the current
batch settings,
Batch Template (.fbt) – to apply settings saved previously
to a special file.
Note: To save batch settings in a file, click the Save button on the General tab
(
Tools>Options menu). A Save Batch Template As dialog will open. Enter the file name.
The following settings will be saved: the
Recognition, Scan/Open Image, Formatting,
and
Check Spelling tab settings, as well as all Formats Settings dialog tab settings. User
languages, user language groups and user patterns will also be saved in this file. To return to
the default settings, click on the
Use defaults button on the General tab. To load the set
tings click the
Load button on the General tab and select the FineReader batch template
(*.fbt) file containing the settings of your choice.
Opening a batch
1. Select the Open Batch item in the File menu. The Open Batch dialog will
open.
2. Select the folder containing the batch you wish to open in the
Open Batch
dialog. When you open a batch, the previous batch is automatically closed
and saved.
FineReader opens the last batch you worked with automatically at startup.
83
Chapter 9. Working with Batches
Page 84
Note: Batches can be opened directly from Windows Explorer:
z Rightclick the batch folder (represented by the icon) and select the
Open with FineReader item in the local menu. FineReader will be started
and the chosen batch opened.
Adding images to a batch
z Select the Open Image item in the File menu or press CTRL+O.
z Select the image(s) you wish to open in the
Open Image dialog.
FineReader will add the image to the open batch and copy the image to the
batch folder.
Note: You can also add images directly from Windows Explorer:
1. Select an image file or group of files in Windows Explorer.
2. Rightclick the selection and select the
Open with FineReader item in the
local menu. If FineReader has been already started, the selected image(s) will
be added to the current batch, otherwise FineReader will be started and the
batch you last worked with opened. This local menu item is only enabled if
the file format is supported by ABBYY FineReader 6.0.
Batch page number
All batch pages are numbered. One batch may contain up to 9999 pages. The page number
is displayed in the batch.
You can renumber pages directly in the
Batch window or in the Renumber Pages dialog.
To renumber pages directly in the Batch window :
1. Click a page in the Batch window or press F2.
2. Enter the new page number.
Once the page number has been changed, all pages in the
Batch window will be reordered
to reflect the new numbering.
Note: If you doubleclick a page number, the page concerned will be opened.
To renumber pages in the Renumber Pages dialog:
1. Select a single page or several pages.
2. Select the
Renumber Pages item in the Batch menu.
3. Set the new number for the first page selected (the page with the lowest
number).
84
ABBYY FineReader 6.0 User’s Guide
Page 85
Note: 1. To renumber all batch pages, select the All Pages item in the Renumber
Pages
dialog.
2. To renumber only part of a batch:
z Select the pages you wish to renumber in the
Batch window.
z Select the
Selected pages item in the Renumber Pages dialog.
3. If you want selected pages to be renumbered continuously, select the
Continuous page numbering option. For example, were this option to be
selected in the case of page numbers 2,5, and 6, and 1 chosen as the first
number, on renumbering the page numbers would become 1,2,3. Otherwise
(i.e. if the
Continuous page numbering option is not selected), on
renumbering page numbers 2,5, and 6 would become 1,5,6. The first page
has been assigned the chosen number, but the remaining pages have
retained their original numbers.
Note: If you renumber only certain batch pages, and in the process allocate
a number to a page that is already in use, a warning to this effect will be
issued, and the whole operation will be undone.
Closing a batch page or the whole batch
To close a batch page:
z Select the Close current page item in the Batch menu.
To close a batch:
z Select the Close Batch item in the File menu.
Note: The batch will be automatically saved when you close it.

Note: Deleting a batch involves deleting all its contents, i.e. all its pages (images and text)
and related files e.g. user patterns, user languages, etc. The batch folder will, subsequently, be
empty.
z To delete a batch, select the Delete Batch item in the Batch menu.
To delete a batch page:
1. Select the page(s) you wish to delete in the Batch window.
2. Select the

Fulltext search in recognized batch pages
(FineReader Corporate Edition only)
You can search through all recognized pages for words in all of their grammatical forms.
The search pattern may consist of one word or several words. This (These) word(s) may be
in any form (for languages with dictionary support), and the words in the search pattern
may be located at any distance from each other in the text and in any order.
To carry out a fulltext search:
1. Select the Advanced search item in the Edit menu or press ALT+F3.
2. The

Network Document Processing
The ABBYY FineReader Corporate Edition is especially designed for network docu
ment processing. Each computer involved in network processing must have a sepa
rate copy of FineReader installed (for more information on network installation of
FineReader, see under "Installation on a Network Server and on a Network
Workstation").
The ABBYY FineReader Corporate Edition allows you to do the following:
1. Work with the same batch over a network
The Corporate Edition allows you to increase the speed at which documents are
processed. In addition, the whole process is tracked, so that the logins and com
puter i.d. numbers of all those involved in opening, scanning, recognizing, and
checking batch pages are noted. Changes made by a user are not userspecific and
apply to all users of the same batch.
2. Group work with the same user languages and user dictionaries
The ABBYY FineReader Corporate Edition allows users to work with and expand
(e.g. while running a spell check) the same user languages and dictionaries simulta
neously.
3. Group work with customized dictionaries for languages with dic
tionary support
ABBYY FineReader provides builtin dictionaries for languages that have dictionary
support. These dictionaries contain the most commonly encountered words, but
might not include proper names, specialized technical terms, acronyms, etc. Adding
the latter to customized dictionaries increases recognition quality and speeds up
the spellchecking process. This is because FineReader searches for a dictionary
entry for each word it encounters. In addition, the ABBYY FineReader Corporate
Edition allows users to work simultaneously with the same customized dictionary.

Page 88
Work with the same batch over a network
(FineReader Corporate Edition only)
1. Create/Open a batch and set up the required scanning and recognition
options.
2. Run FineReader and open the relevant batch on all computers that are to
process it.
3. Run background recognition (
Process>Start background recognition)
on all computers involved in recognizing the batch.
4. Start the scanning on a computer equipped with an ADF scanner.
Tip: If your highspeed scanner does not support the TWAIN standard,
scan your pages directly into the FineReader batch folder. This can be done
by scanning the images on the computer attached to the scanner (using the
scanning application supplied with your scanner), and specifying the
FineReader batch folder as the folder to which images should be saved. Note
that scanned images should be named as follows: 0001.tif, 0002.tif, 0003.tif...
etc., in accordance with the order in which they are scanned.
5. FineReader will automatically detect and process all the images you scan.
6. Edit the recognized text (if necessary) and save it to file or export it to the
application of your choice.
You can monitor page status (i.e. see whether a page has been scanned, recognized, edited, or
exported, etc., and by whom) in the
Batch window. All this information is displayed in the
corresponding columns in the
Details batch page view. To set up the Details page view:
z Rightclick the
Batch window and select the View>Details item in the
local menu.
You can customize the
Details page view e.g. specify the columns you want displayed in the
Batch window or select the characteristic by which pages are to be sorted:
z Rightclick the
Batch window and select View>Customize. Set the neces
sary options on the
Details tab of the Batch View Settings dialog.
If batch pages are to be processed using several computers, FineReader will distribute the
workload automatically between them: each newly scanned page is allocated to the first free
workstation able to accept it (background recognition must be running on the workstation
concerned) and no other workstation will be able to access it until recognition is complete.
To refresh the batch page list, press
F5 or select the Update page list item in the Batch
menu. Once a page has been recognized, any other workstation (or indeed the same worksta
tion) can open the page concerned for checking, editing and saving. Changes made by a user
are not userspecific and apply to all users of the same batch.
88
ABBYY FineReader 6.0 User’s Guide
Page 89
Note: If your batch contains a large number of pages, recognition speed will be increased if
you use “Background mode” in combination with a multiprocessor system.
Group work with the same user languages
and dictionaries
(FineReader Corporate Edition only)
Create a batch and set up the required scanning and recognition options.
All the user languages and dictionaries you attach will be stored in one folder. By default this
will be the batch folder. Before you can create a user language that makes use of a user dic
tionary, you have to specify the folder in which both are to be stored. To specify the folder:
z Click the
Change button in the Language Editor dialog
(
Tools>Language editor) and select the folder in the resulting dialog.
All user languages and related dictionaries will then be stored in this folder.
Once setup is complete, save the batch settings in a batch template file (*.fbt):
z Click the
Save button on the Options>General tab (Tools>Options). In
the
Save Batch Template As dialog, open the folder and enter the file
name.
Before several users can work with the same user languages and dictionaries stored in a new
batch, each of them will need to load the batch settings from the previously saved *.fbt file.
To do this:
Select the Batch template (.fbt) item in the Template field. In the Open Batch
Template
dialog select the desired *.fbt file. The previously saved batch settings, including
user language paths and dictionaries, will be restored, and all users will have the same access
to the user language paths and dictionaries.
Users can also edit their dictionaries. Changes made by one user will be made available for
all other users of the same folder, and, similarly, any user languages present in a folder are
available to all those who load its template. You can find the list of the available user lan
guages and their properties in the
Language Editor dialog in the Userdefined lan
guages
group.
Note that a dictionary cannot be accessed while a user is in the process of adding/removing
a word to/from it. The dictionary is updated when the user clicks the
Add button in the
Check Spelling dialog or any button in the View dictionaries dialog.
89
Chapter 10. Network Document Processing
Page 90
Note: 1. Before you can use the dictionaries contained in a particular folder, you must
have readwrite access to that folder.
2. When a user language is used simultaneously by several users, it will be avail
able as “readonly”, i.e. it will not be possible to change any existing parame
ters. However, entries can still be added/removed to/from the user diction
ary of this language.
Group work with customized dictionaries
(languages with dictionary support only)
(FineReader Corporate Edition only)
Create a batch and select the scanning and recognition options of your choice. By default
the customized dictionaries for the predefined main languages (languages with dictionary
support) are saved in the folder in which the application was installed (in the case of
Windows 2000 – Documents and Settings\[user profile]\Application
Data\ABBYY\FineReader\6.00\UserDictionaries).
To enable several users to use the same customized predefined user dictionaries at the same
time, create a public folder in which all such dictionaries are contained. The folder can be a
local or network folder. To specify the folder:
z Click the
Browse button on the Check Spelling tab of the Options dia
log (
Tools>Options menu). Select the folder in which you wish to store
predefined user language dictionaries.
A customized dictionary can be expanded at will. It cannot be accessed while a word is
being added/removed to/from it, but any changes made immediately become available to all
other users of the same folder when the dictionary is updated. A dictionary is updated when
a user clicks the
Add button in the Check Spelling dialog or any button in the View dic
tionaries
dialog.
Note: If several users wish to use a folder in which custom dictionaries are stored, all users
must have readwrite access to the folder concerned.
