Introduction
This Reference manual covers the various commands and features found in the
ScanWizard Pro scanning software for the Mac OS X system. The reference
information is divided into four major sections, corresponding to the four major
windows of the program:
• Preview
• Settings
• Information
• Scan Job Queue
The Reference manual is part of the comprehensive documentation included
with your Microtek scanner package.
Another important component of the documentation, the User's Guide, covers
basic and advanced scenarios for scanning (e.g., how to scan film, how to scan
multiple jobs, etc.).

Page 13
The Context Concept
The “Context” feature in ScanWizard Pro has to do primarily with setting up
scan jobs and customizing your scanning environment for increased scanning
efficiency. It is a powerful tool to help you get the most productivity out of
your scanner, especially if you do many similar scanning jobs.
A “context” is really a Mac OS folder that contains any number of scan job
files and a ScanWizard Pro preferences file with information on these scan
jobs. Think of a context as a complete scan setup or environment, with each
context having its own characteristics, such as scan material (reflective,
positive, or negative film), ColorSync profile selections, scan quality control,
interpolation method, and others.
A good example in illustrating the concept of the context is through the use of
templates. For instance, you may set up four contexts for your most frequent
scanned work — reflective scans, a 35mm template, a 4" x 5" template, and a
negative filmstrip template. You can then switch easily and freely among these
contexts to maximize your productivity. (For more information, see the
SnapTrans Templates command.)
When you quit or switch to another context, the settings of the current context
are automatically saved. You will have exactly the same setup when you run or
switch back to this context, so there is no need to start from scratch.
You can set up as many contexts as your hard disk can hold. And because
contexts are regular Mac OS folders, you manage them (e.g., copy, duplicate, or
delete) easily by using the Finder.
The ScanWizard Pro context can be easily customized to your particular need
and used for many applications, such as the following:
• Repeated or frequent use of project/job settings
• Saving different experiments on the same project/job
• Different setups involving scan material selections, CMS settings, scan jobs
• Various templates of a user's work
• Scanner sharing among multiple users
• Archiving of scan projects/jobs
• Proofing on prescans and adjustments before final scans

Page 14
New ScanWizard Context
This command creates a new context folder with default settings for scanning.
Subsequent scan jobs are then stored in the newly created context folder. The
newly created context also becomes the current context.
To create a new context:
1. Choose New ScanWizard Context from the File menu.
2. When the browser dialog box appears, create a new folder.
Load ScanWizard Context
This command loads a previously saved context folder. The loaded context then
becomes the current context.
To load a context:
1. Choose Load ScanWizard Context from the File menu.
2. When the browser dialog box appears, select the folder to be loaded, and
click the Select button at the bottom of the dialog box.
Save ScanWizard Context As
This command lets you save an extra copy of the current context to a new
location. The settings of the current context are saved first and then copied and
switched to the new location. This is particularly useful when you want to work
on a new context based on the current context settings.
To save a context:
1. Choose Save ScanWizard Context As from the File menu.
2. When a dialog box appears, choose the folder where the scan jobs will be
saved. Subsequent scan jobs are then saved to the specified folder.

SnapTrans Templates
This command lets you choose the particular SnapTrans™ template you wish to
use with ScanWizard Pro. The templates are holders designed to secure a
variety of films, such as 4"x5" film, 6cm x 9cm film, 35mm filmstrip, and
35mm slide (landscape or portrait orientation).
To use the SnapTrans templates:
1. Choose SnapTrans™ Templates from the File menu. The SnapTrans
Templates dialog box appears.
2. Choose the correct scan material.
3. Select the template to be loaded by clicking the template icon.
4. Take note of the name and location of the folder to where scan jobs will be
saved, or specify your own folder name and location.
5. Click the Save button. The selected set of pre-defined scan jobs based on
the template you chose is copied to your designated folder; i.e., a new
"Context" folder has been created for you. The Scan Job window will also

Scanner Driver Manager
The Scanner Driver Manager keeps track of the scanners being used on your
system and the bus / ID numbers occupied by the scanners. By keeping a record
of this information, the Scanner Driver Manager allows ScanWizard Pro to start
up more quickly, as there is no need to look for scanners that are anot available.
When ScanWizard Pro is run the first time, all connected scanners are added to
the list.
To add a scanner:
Follow the hardware installation instructions for connecting a scanner to your
system. You can then use the Scanner Driver Manager in ScanWizard Pro to
add or include the connected scanner to your scanner list.
Note: You will have to follow the steps below if you change hardware
configuration such as the SCSI ID or SCSI bus.
1. Go to the Scanner menu in the Preview window, and choose Scanner
Driver Manager. A dialog box will appear showing the current scanner list
with the corresponding SCSI, USB, or FireWire bus/ID number.
2. Click the Find Scanners button. In case you have added new scanners, the
newly found scanners will be appended to the scanner list. If a scanner on
the list is not detected (not turned on, not ready, or removed from the
system), the model will not be removed from the list but will have a
question mark before it. See below for details on how to remove a scanner.
3. Click the Close button to close the dialog box.

Scanner Controls
This command lets you use some of the special features of your scanner, such
as lamp control.
Note: Not all scanner models support these features. If your scanner model is
not supported, the Scanner Controls command will be grayed out in the
Scanner menu.
Lamp Control
This the power-saving feature of the scanner lamp to save energy and extend
the life cycle of the lamp. By default, the lamp turns off automatically if the
scanner is idle for 15 minutes. You can change the lamp idle time in your
preferences or disable this feature completely by unchecking the Auto PowerSaving Mode check box.
By default, the lamp warm-up time is 3 minutes. A lamp warm-up dialog box
will appear if you try to perform a scan or preview operation without the lamp
having fully warmed up. If the lamp is not fully warmed up, the light intensity
of the scanner may not be stable and may adversely affect the quality of your
scanned image.
The current lamp status is indicated. You may specifically turn the lamp on or
off if you wish. Please note that the lamp On / Off state is automatically
controlled by the software, and no user intervention is necessary. You may want
to do this manually if and only if you wish to turn on and warm up the lamp a
few minutes before you actually finish your scan job editing.

Scan Material
This command allows you to select the correct scan material. Scan materials
can be classified into three types:
• Reflectives, such as photographs or prints.
• Positive transparencies, such as slides.
• Negative film, such as the negative film you use for your camera.
The default scan material depends upon the scanner you are using, and the
choices available to you in the Scan Material submenu will also depend on your
equipment.
For instance, the Positive and Negative options appear only if you are using a
dual-bed SnapTrans™ scanner such as the ScanMaker 8700 or if you are using
a Transparent Media Adapter (TMA) with your flatbed scanner.
If you are scanning negatives or positives, make sure you specify the correct
scan material, or you will get inaccurate scanning results.
To choose your scan material:
1. Choose the Scan Material command in the Preferences menu. From the
submenu that appears, select your scan material; a check will appear next
to the selected option.

Color Matching Setup
Color Matching is an important feature of ScanWizard Pro that ensures
consistent color — from the initial input stage when an image is captured by
the scanner, to the final output stage when the image is output to your monitor
or printer (through either the Kodak CMS or Apple ColorSync™ technology).
Color matching is a critical component in the imaging process, because the
color space of your monitor is different from that of your printer (in terms of
output devices), just as the color space for RGB mode is different from the
color space for CMYK mode (in terms of image types). For this reason, color
matching was developed to allow an equivalent "mapping" of colors from one
device or from one color space to another, ensuring that no major color shifts
occur in the transferrence process.
To use the ScanWizard Pro color matching function:
1. Set up the Kodak CMS and Apple ColorSync features correctly at the time
that ScanWizard Pro is installed. For more information on this procedure,
refer to your Kodak or Apple system documentation.
2. The first time you launch
ScanWizard Pro, you will be
prompted to set up color
matching for your scanner.
You may also access the color
matching parameters for
ScanWizard Pro at any time
in the future by choosing the
Color Matching Setup
command in the Preferences
menu.
Before you proceed with specifying
your Color Matching Setup options,
you should know if the image-editing
or page-layout application you use
to edit or process scanned images is
ColorSync-savvy or not (e.g., Adobe
Photoshop 5.0 or later is ColorSyncsavvy; Adobe Photoshop 4.0 is not).
This is because the settings in the
Color Matching Setup dialog box will
vary, depending on the imageediting application you are using.
A non-ColorSync-savvy application
is a program that does not know
how to read or handle embedded
ICC profile information. In this
case, the ICC profile data is
ignored.
For more information, see the
section titled Using images in thirdparty applications in the Appendix.
Reference: The Preview Window 23
Page 30
Color Matching Setup cont.
A. Display using monitor compensation
For ColorSync-savvy applications such as Adobe Photoshop 5.0.2 or later,
check this box, which pertains to how your monitor displays color, relative to
the RGB Destination color space. Checking this box ensures that there are no
unexpected color shifts between your selected RGB Destination space and your
monitor. Checking or unchecking this box affects only the way the image data
is displayed and not the image data itself.
For more information, see the section titled Using images in third-partyapplications in the Appendix.
B. Monitor
The monitor selection shown here is the monitor set in your Monitor Control
Panel. To verify this information, go to your System Preferences, then Displays.
Your selected monitor will be shown, which should be the same as the entry in
this dialog box. This setting only affects how the image is shown on the screen
— not the final scanned image.
C. Native Mode RGB color matching
This option is available only for Native color space mode. This check box
should generally be checked unless you want to scan raw color data, in which
case you lose the compensatory effects of the Color Matching System. Take
note that it is not desirable to scan in raw data and then perform ColorSync data
conversion, which will not generate the correct CMS effect.
For more information, see the section titled Using images in third-partyapplications in the Appendix.
24 Microtek ScanWizard Pro for Mac OS X
Page 31
D. Embed ICC destination profile in scan image
For ColorSync-savvy applications such as Adobe Photoshop 5.0 or later, check
this box. This feature will enable ScanWizard Pro to embed the Destination ICC
profile into the image data. The information will then be properly interpreted by
Photoshop or any ColorSync-savvy application.
For non-ColorSync-savvy applications such as Adobe Photoshop 4.0, uncheck
this box if turning it on causes any kind of problem (computer crashes, weird
color effects, etc).
For more information, see the section titled Using images in third-partyapplications in the Appendix.
E. RGB Destination
This feature lets you select the ICC profile in the ColorSync folder for
outputting images to the RGB color space. You may select from Scanner RGB,
Monitor, RGB printer (e.g., inkjet printers), a special color space, or the Adobe
Photoshop 5.0 internal color space profile. For Photoshop 5.0 users, you may
export its internal color space to an ICC profile. If you are not sure what to
choose, select your current monitor profile.
A large number of RGB profiles is supplied by ScanWizard Pro. If you do not
see the ICC profile for your monitor or RGB device, contact your device
manufacturer. To load a specific ICC profile from a different folder, click the
RGB profile button (beside the drop-down menu), and select the profile you
need.
F. CMYK Destination
This feature lets you select the ICC profile in the ColorSync profile folder for
outputting images to the CMYK color space. ScanWizard Pro has supplied a
large number of CMYK profiles. If you do not see the ICC profile for your
printer, contact your printer manufacturer. To load a specific ICC profile from a
different folder, click the CMYK profile button and select the profile.
G. Preview check box
This immediately updates the Preview window image when a new color profile
is selected, so that the preview image reflects colors consistent with the newly
selected color profiles.
H. Profile Info
This lets you review the information on the currently used ICC profiles.

White/Black Points Setup
This command provides you with advanced controls for setting the clipping
points for your white and black points, as well as determining the output levels
for the white/black points on your printer.
To use this feature:
1. Choose the White/Black Points Setup command from the Preferences menu.
2. As an alternative, you can click this command from the Color Correction
Menu. This is also the same thing as clicking the White/Black points tool in
the Settings window and then clicking the Setup button from the dialog box
that comes up. When the dialog box comes up, specify your preferences.
A. Auto Clipping
The Auto White Point Clipping and Auto Black Point Clipping fields allow you
to specify the percentage by which the white and black points, respectively, can
be clipped from the histogram. The clipping is done after you click the Auto
button in the AIC White/Black Points dialog box.
For example, if you specify 10 percent as your White Point clipping value and
then click the Auto button, the white point on the histogram is adjusted so that
10 percent of the color information is "clipped" or ignored. The resulting 90
percent information leftover is then remapped, resulting in an image with less
highlight detail.
The same principle above applies to the Auto Black Point Clipping feature,
which governs the black point for shadows.
These fields are normally used by more advanced users, and the features are
taken care of automatically if you have set up Color Matching correctly early on
in ScanWizard Pro.

B. Output Levels
The Minimum Output Level lets you set the minimum output level of the black
point. The higher the percentage value, the lower the contrast will be.
The Maximum Output Level lets you set the output level of the white point. The
lower the percentage value, the lower the contrast will be.
LCH Color ModeNative Color Mode
C. High and Low Value Markers
This lets you adjust the settings that define the High Value Marker (shown as a
black circle) and the Low Value Marker. The High Value Marker is shown as a
black circle in your preview image, while the Low Value Marker is shown as a
white circle. You can specify the range of the markers to either the entire
preview (by selecting the “Overview or Preview image” option) or to only
within the scan frame (by selecting the “Current Scan Frame”).
In the White/Black Points Setup window, clicking the “Preview” button will
obtain instant results; clicking the “OK” button lets you exit from the Setup
window and applies the High and Low Value Markers setting you have made to

Overview Setup
This command lets you set the area you want to overview off the scanner bed
and provides some overview options as well.
By default, ScanWizard Pro overviews the maximum scan area as determined
by your scanner model's bed size. You can, however, customize the overview
area so that the scanner consistently overviews only the specific dimensions
you have in mind. For example, if your maximum scan area is 8.5" x 14", you
can customize the overview area so that it consistently overviews, say, 4" x 8"
of the bed size.
As a rule of thumb, it is best to use the default maximum settings. You should
change the overview area only if your subsequent overview is too large to be
shown in entirety, or too small for reliable previewing. A smaller overview area
will increase the overview resolution for clearer image viewing. You may also
wish to change the size of your overview to improve performance. Generally, a
shorter overview time results from the scanner motor travelling a lesser
distance.

A. Overview Area
This represents the scan bed size. The dimensions of this overview area will
depend on the size as stipulated by the Size and the Left/Top/Width/Height
settings in the dialog box.
B. Size
This option lets you choose whether to do an overview of the Maximum area or
a Custom area.
• Maximum refers to the maximum area that can be overviewed. The dimen-
sions of the maximum area vary, depending on your scanner model. Take
note that transmissive scan areas are smaller.
• Custom refers to the area as determined by the dimensions you specify in
Section C below.
C. Left, Top, Width, Height
These edit boxes let you specify the dimensions of the overview area.
• To p and Left refer to the starting points of the overview area on the X and Y
coordinates.
• Width is the expanse of the overview area. Height is the depth of the
overview area.

D. Keep Overview Image After Quit
If this box is checked, the overview image will be kept when you quit
ScanWizard Pro, and the same overview image will be displayed again when
you run ScanWizard Pro the next time.
E. Fast Overview
If this box is checked, the overview process is speeded up. The trade-off to
increased speed is a slightly downgraded overview image. If you do not care
about the image quality of the overview image, check this box.
F. Warn Me if Overwriting Prescan
If this option is checked, a confirmation message appears, notifying you that a
previously prescanned image exists. This confimration is usually useful
because doing a new overview will delete all prescan images.
G. Auto Overview when ScanWizard Pro is Run
If this box is checked, an overview is performed automatically when you run
ScanWizard Pro.
H. Overview button
This button performs an overview and shows the overview image in the
Overview Setup dialog box.
Changing the Size of your Preview Area
1. Go to the Preferences menu in the Preview window, and choose Overview
Setup.
2. When the Overview Setup dialog box appears, click the Overview button to
preview the entire bed. This will help you determine how you wish to
resize the overview area.
3. To change the overview area, you can:
•Drag a rectangle that approximates the size of the overview that you
wish; or
•Enter the appropriate values for the Top, Left, Width, and Height edit
boxes. The new dimensions will take effect on the next Overview —
when you click the Overview button again in the Preview window (not
the Overview button in the Overview Setup dialog box).

Prescan Setup
The Prescan Setup command lets you determine the margin surrounding the
prescan image and the size of the prescan image.
To change the margin or size of the prescan image:
1. Go to the Preferences menu in the Preview window, and choose PrescanSetup.
2. When the Prescan Setup dialog box appears, specify your choices.
A. Fast Prescan
If this box is checked, the prescan process is speeded up, but the resulting
image is grainier. If unchecked, the prescan process is slowed down a bit, but
the resulting image is of better quality.
B. Keep All Prescan Image(s) After Quit
If this box is checked, the preview images stay after you exit ScanWizard Pro.
Otherwise, all prescan images are deleted after you exit ScanWizard Pro.
32 Microtek ScanWizard Pro for Mac OS X
Page 39
C. Prescan Image Margin
This option allows you to specify how wide or narrow the margin around the
scan frame is for the prescan image. Options are: Minimal, Small, Medium, and
Large. Smaller margins give you more room to capture the preview image,
while larger margins will allow you to have more room to expand your scan
frame.
This is helpful because selecting the exact scan frame (through the Scan Frame
tool) can never be a completely accurate process, and what appears to have
been selected by the scan frame when you view the image in the lowerresolution overview may or may not actually include the portion you wish. The
margin — depending on how wide or narrow it is — can then provide a berth
or allowance for extending the boundaries of the scan frame around the prescan
image. Margin options include minimal, small, medium, and large.
D. Prescan Image Dimension
This option lets you specify how large the prescan image will be: Full screen
("screen" meaning your main monitor), 75% screen, 50% screen, and Fit
Preview Window. The larger the size, the higher the prescan resolution. The
maximum prescan resolution is the scanner's optical resolution.
E. Background Prescan
If checked, the background prescan function is enabled. You can assign a
number of scan jobs to execute a prescan while carrying out other jobs in the
meantime (e.g., performing color correction to other scan jobs). If unchecked,
this function is disabled.
Reference: The Preview Window 33
Page 40
Invert
This command inverts images of all scan jobs. Take note that all scan jobs are
inverted at the same time; you cannot invert an individual scan job alone.
When an image is inverted, the brightness value of each pixel is converted to its
inverse value. In the case of 24-bit images, for example, a pixel in a positive
image with a value of 255 is changed to 0, and a pixel with a value of 5 is
changed to 250.
Inverted imageOriginal
To use this feature:
Choose the Invert command in the Preferences menu. A check appears next to
the command when it is enabled.

Retain Scan Module after Scan
This command allows you to keep the ScanWizard Pro interface running after
scanning is completed and the image delivered to your image-editing software.
This way, you do not have to go back to the File-Acquire process to start
ScanWizard Pro all over again.
Note: This command can be used only in applications that allow you to retain
the scan module after a scan is completed. Some applications will not retain the
scan module even if this option is enabled.
To use this feature:
Choose the command Retain Scan Module after Scan in the Preferences menu.
A check appears next to the command when it is enabled. If you wish to see the
scanned image in your image-editing software after scanning is completed, you
will need to quit ScanWizard Pro to see the image.

A. Smoked Glass Background
This option lets you apply a smoked glass background that makes your scan
jobs stand out more clearly and allows you to focus on the scan jobs. This
feature can also be used for multiple scan jobs to show their respective image
modes (example: one job in color, another in B&W), as well as their imageediting settings.
The framed part of the
image (inside the marquee)

B. Working Color Space
This option lets you choose between the default LCH color space or the Native
color space.
C. Scan Quality
This option allows you to select the image quality by controlling the scanner
hardware and the maximum image processing depth.
•Speed: Choose this option if your primary concern during scanning is
speed. Image data is delivered faster and the image data is processed in 8
bits per channel.
•Quality: This is the default setting. Scanned data is delivered a little slower
but in high quality, and the image data is processed in 8 bits per channel.
•Best Quality: This setting is available only to higher-depth scanners (10-,
12-bit, or higher). Scanned data is delivered a little slower but in high
quality, and image data is processed in maximum bits per channel (i.e., 10-,
12-bit, or higher), and then converted to the desired output depth. This
special operation results in the best image quality possible.
D. Interpolation Mode
The interpolation mode controls the way ScanWizard Pro interpolates (either
expands or shrinks) image data. Interpolation always occurs when the scan
resolution you select is different from the scanner's optical resolution. The
trade-off is speed vs. quality. If your application requires higher quality, use Bilinear (Quality) mode, especially if you are scanning higher-resolution line art
images.
1. Nearest Neighbor (Speed): When this option is selected, ScanWizard Pro
will do the following:
•Expanding (when scan resolution is higher than optical resolution):
Linear interpolation is used (i.e., makeup pixels are created by using
the average of the neighboring pixels).
•Shrinking (when scan resolution is less than optical resolution): Pixel
drop is used to match the resolution.
2. Bi-linear (Quality): When this option is selected, ScanWizard Pro always
scans in a high-enough resolution and then applies a bi-linear interpolation
algorithm to expand or shrink image data. This is a complicated
mathematical formula, and thus, takes longer to process.

E. Scratch Directory
The scratch directory is the folder where ScanWizard Pro creates temporary
files, with the temporary files deleted at the end of an operation. You should
change to a different folder only if the scratch directory is located in a disk
volume that is too small for scanning operations. To specify a new scratch
directory, choose Other Directory... from the menu.

Zoom tool
The Zoom tool lets you zoom in (magnify) and zoom out (reduce) your view of
the image. Only your view of the preview image is changed; the actual size of
the image remains unaffected.
Each click of the zoom tool magnifies or reduces by a factor of 2. Thus, the
magnification levels increase from 100% to 200%, to 400%, to 800%, and to
the maximum 1600%. When you reach the maximum magnification factor, the
center of the Zoom tool will appear empty.
To zoom out (reduce), hold down the Option key and with the Zoom tool
selected, click the image. A minus sign will be in the middle of the lens to
indicate the image is being zoomed out.

Tag Windows tool
The Tag Windows tool lets you set the shadow (black) point and highlight
(white) point of an image.
It also creates tag windows, which are used to isolate and identify precise
colors in a given image, providing a visible and retrievable record of color
values. This way, ScanWizard Pro lets you pinpoint and “tag” the color on the
image, showing you the original or “Before” values, as well as the corrected or
“After” values following the application of image adjustment controls.
The Tag Windows tool is useful especially if you are making color adjustments
based on known mathematical values, as the displayed color information
provides a basis for knowing how close or accurate are the color changes that
have been made.
Also in the tag window are the Magic Diamonds for adding or removing a color
cast, as well as for setting the shadow / highlight point.

details).
2. To select multiple scan jobs, press the Shift key and click
on the jobs to be selected in the Scan Job Queue or
Preview window.
3. Click the Prescan button in the Preview window.
Multiple prescans are created in the process,
corresponding to the number of scan jobs defined, and
you can then switch among the various prescan images.
The Scan button scans the images on your scanner and
delivers the images to your image-editing software. The
images that are scanned are the scan jobs that have been
checked in the Scan Job Queue window.
Note: If the Retain Scan Module After Scan option (in the

Rulers, Unit of Measurement
The rulers on the top and left sides of the Preview window help you with
measurement and alignment, marking off measurement according to the
selected unit (inch, pica, pixel, etc.).
The rulers change when dimensions are altered in the preview area of the
Overview Setup command (in the Preferences menu). For example, if you
change the preview area size from 5" x 8" to 6" x 9", the rulers will change
accordingly.
The unit of measurement can be selected in two ways:
• Through the Unit box in the Settings window.
• Through the arrow at the corner where the rulers meet in the Preview
window. The drop-down menu through this method also lets you format the
text color and background color of your rulers.
The options for unit of measurement include inch, centimeter, millimeter, point,pica, and pixel. The pixel option is dimmed if the selected resolution unit is lpi.

Type
The Type box shows you the image type of the current scan job. ScanWizard
Pro allows direct scanning in the following color spaces described below.
A. RGB: RGB (Red, Green, and Blue) images use three colors to reproduce
up to 68.7 billion colors. Because scanners and monitors are RGB devices,
the RGB color space is the most commonly used space for capturing and
displaying images. ScanWizard Pro offers standard RGB and 48-bit RGB
color selection, with the 48-bit option available for the ScanMaker 5,
ScanMaker 2000, the Artix line of scanners, and other Microtek
professional pre-press scanners.
B. Grayscale: Grayscale images use shades of gray to simulate gradations of
color or tonal values, and contain 8 bits per pixel. The Grayscale 16-bit
option is provided in ScanWizard Pro for professional pre-press scanners.
C. CMYK: CMYK images are made up of the standard four colors (cyan,
magenta, yellow and black or K) for separated film or digital files used for
sheetfed or web offset printing. CMYK mode instantly converts the
scanner’s RGB input to the CMYK color space. CMYK images are four-
channel images, containing 32 bits per pixel.
D. Lab Color: Lab images are three-channel images containing 24 bits per
pixel. Lab mode is useful for editing a pixel’s luminance but not its color
values. Lab mode produces device-independent color and is recommended
for moving images between systems or printing to a PostScript Level 2
printer.
E. Web / Internet Colors: This mode is useful for displaying images on the
Web or Internet. Output for the Web / Internet color mode in ScanWizard
Pro is 8-bit, 256 indexed color images in the sRGB color space.
58 Microtek ScanWizard Pro for Mac OS X
Page 65
F.256 Colors (Default) / 256 Colors (Custom): These are single-channel
images (8 bits per pixel) that use a color lookup table containing up to 256
colors. The file size is smaller for images in this mode. As an initial setting,
selecting 256 Colors (Default) uses an Adaptive palette with Diffusion. If
the 256 Colors (Custom) option is selected, the dialog box below appears.
•Palette: The Palette option lets you choose the method for creating the
color palette table. Uniform uses a 6-6-6 fixed color palette table.
Adaptive (default) creates a color palette table from the more
commonly used areas of the color spectrum that appears in the image.
•Dither: The Dither option can improve the color quality of the 256indexed color image for photographs or continuous-tone images, using
a technique of mixing available colors to simulate missing colors.
None provides no dithering. Pattern uses a structured pattern to
simulate missing colors. Diffusion (default) uses the error diffusion
technique to dither colors and produces the best quality for 256 colors.
G. Line art: Line Art images are made up of one bit of color (black or white)
per pixel. Few editing options are available in this mode, but this mode is
useful for images consisting purely of black and white or even single
colors, such as mechanical drawings, blueprints, or fine-line illustrations.
H. Black-and-White Diffusion: This is a single-bit black-and-white image
dithered with error diffusion. The black and white pixels are arranged in a
way as to “fool” the eye into seeing gray.

Resolution settings
The settings related to resolution include the resolution box, the resolution list
box, and the resolution unit.
Resolution is the sampling of image pixels per measurement unit or the amount
of pixel information stored in an image. Together, the image resolution and
dimensions determine the file size of the image, which is measured in kilobytes
(KB) or megabytes (MB).
The resolution of an image is important in determining the quality of the output
image. Resolution is also directly related to file size, and the higher the
resolution, the larger the resulting file size will be.
When dealing with resolution, remember to distinguish between optical
resolution and interpolated resolution.
Optical resolution is the "real" resolution as measured by the scanner's optics.
Interpolated resolution is software-enhanced resolution and can be useful for
enlarging very small images or for printing line art to obtain superior results.
A. Resolution box
This shows the resolution setting. To set your resolution:
Enter a resolution setting in the Resolution edit box, then press Enter. If the
value you enter is too high or too low, the maximum or minimum resolution
value is entered for you instead.
Depending on the type of image you have selected (grayscale, color, line art,
etc.), a default resolution is displayed in the resolution box. After you enter
your own resolution value, this value is then recorded for subsequent use, until
a new value is entered and takes over.
B. Resolution list box
This provides predefined resolution values for easier selection of the resolution
setting.
To select your setting, press the up/down arrows next to the Resolution box,
and choose your setting from the list box.

Page 67
C. Resolution unit
The unit of measurement for resolution is in ppi (pixels per inch) or lpi (lines
per inch). Take note that lpi settings are dimmed if the ruler unit is in pixels.
To select your resolution unit:
• Choose ppi if your scanned images are intended for on-screen display. In
this case, you need not go higher than the target resolution of your monitor
(usually 72 dpi for Macintosh and 96 dpi for Windows). A higher resolution
value will simply increase the file size of your image without any perceptive
improvement in image quality.
• Choose lpi if your scanned images are to be printed. If you choose 1x, for
instance, your scanned image will be printed at 133 lines per inch, resulting
in a 133-dpi image. At 1.5x, the image will be printed at 199.5 dpi; and at
2x, the image will be printed at 266 dpi. The Custom option allows you to
set an lpi value of your own specification.
In choosing an appropriate lpi value, keep in mind that if the resolution is
too low, the image becomes pixelized, resulting in a deterioration of image
quality. (Pixelization is the process in which the Postcript language uses a
single pixel's color values to create more than one halftone dot.) Conversely,
if the resolution is too high, the file size becomes unwieldy, and your file
ends up containing more information than the printer needs, slowing down
the file transfer and the printing process.

Scan Frame and related settings
These settings allow you to adjust the various factors that affect your image,
including the width and height of your image when it is first scanned (Scan
Frame settings), the Scaling factor (how big or how small the resulting scanned
image will be), and the dimensions of the image when it is output (Output
settings).
Locks
Scan Frame settings
Output settings
Scaling
The Scan Frame settings, Scaling, and Output Settings work closely with the
Locks beside them.
In the default settings of ScanWizard Pro,
where none of the locks are in place, take note
of the following:
• Changing the Scan Frame settings (width
or height) will change the Output settings
(width or height).
• Changing the Scaling will change the
Output settings (width AND height).
• Changing the Output settings (width or
height) will change the Scan Frame settings (width or height).
62 Microtek ScanWizard Pro for Mac OS X
Note: When an illegal
value is entered (e.g.,
the input width
exceeds the scan
frame size), the value
will appear in red as a
flag or warning
indicating an out-ofrange value.
Page 69
A. Scan Frame settings
The Scan Frame settings (width and height) represent the area on the scan bed
that you wish to scan.
To specify your settings, enter the dimensions manually in the width and height
edit boxes; or use the Scan Frame tool to define or resize your scan frame.
Changes made in the Preview window are automatically displayed in the Scan
Frame setting edit boxes.
If you wish, you can also choose from a menu of predefined Scan Frame
settings. To do this, point your mouse to the words "Scan Frame" in the Settings
window, and choose the setting you wish from the drop-down menu that
appears.
Reference: The Settings Window 63
Page 70
B. Output settings
The Output settings (width and height) represent the dimensions of the image
when it is output to either the monitor or the printer. If the size of the image to
be output is different from the size of the original source image, adjust the
scaling percentage, or manually increase / decrease the output values
accordingly.
If you wish, you can also choose from a menu of predefined Output settings. To
do this, point your mouse to the words “Output” in the Settings window, and
choose the setting you wish from the drop-down menu that appears.
• Add / Remove Custom Setting: These options let you customize and create
your own output settings for use in subsequent scans.
64 Microtek ScanWizard Pro for Mac OS X
Page 71
C. Scaling
Scaling lets you create larger or smaller images
from the original source image. Take note of the
following:
• Keep the scaling at 100% if you are outputting at
the same size (e.g., a 4” x 5” original to be
output at the same size).
• Reduce the scaling if you are outputting your
image at a smaller size (e.g., a 4” x 5” original to
be output to 2” x 2.5”). Increase the scaling if
outputting at a larger size.
To choose the scaling percentage, click the up/down arrow next to the scaling
box, or enter a value in the scaling edit box.
If you wish, you can also choose from a menu of predefined Scaling settings.
To do this, point your mouse to the words "Scaling" in the Settings window,
and choose the setting you wish from the drop-down menu that appears.
• Film scale mapping: Choose your image material and the output dimension.
For example, “35mm to 5” x 7"” means your image source is 35mm film,
and output size is 5" x 7".
• Add / Remove Custom Setting: These options let you customize and create
your own image-mapping scale for use in subsequent scans.
Scaling is also affected by your resolution setting. When you change resolution
and specify a value that has no exact equivalent for scaling, the scaling may be
affected and adjusts itself to the nearest allowed value. For instance, if your
resolution is 100, your scaling becomes 99 (instead of a full 100), because that
is the closest scaling equivalent, given the resolution value.
D. Image Size
The Image Size field indicates how big the file will be when you accept the
dimensions shown in the edit boxes, together with the resolution setting that
you have selected. Size is calculated automatically. The resulting file size
depends on the image type (color, grayscale, etc); resolution; and dimensions of
the image.
E. Unit of Measurement
The Unit of Measurement lets you select the desired unit (inch, cm, mm, point,
pica, pixel) for your image dimensions.
Important: Make sure you select the correct unit of measurement before
entering any of the values for width or height in the Scan Frame Settings or
Output Settings.

Locks
The Locks control the behavior of the Scan Frame settings and the Output
settings. A third Lock lets you keep the proportion for image width and height.
C. Keep Proportion lock
B. Output lock
A. Scan Frame lock
This lets you lock in the settings of your scan frame,
so that the width and height dimensions of the frame
are always preserved no matter where you move the
frame in your preview image.
If you know the exact input size for your image, or if
you wish to “lock” the settings of your scan frame to
a particular size, enter the Scan Frame width and
height values first, then click the Scan Frame lock.
Your scan frame will be “fixed” at those values, so
even if you move the scan frame around the preview image, the dimensions of
the frame itself will remain unchanged.
Note: The Scan
Frame Lock and
Output Lock are
each mutually
exclusive. This
means that only one
lock can be used at
a time.
B. Output lock
This lets you lockin the values specified for the width and height of the image
when it is output. For example, if you know the exact output size for your
image, enter the output width and height values first, then click the Output lock.
The image will then be scanned and output at the values you specify.
Note: If any of the input values are changed after the lock is on, the scaling will
be adjusted automatically to preserve the output dimensions correctly.
C. Keep Proportion lock
This lets you keep the proportion of the image width and height despite
changes made to either setting, and thus preserves the aspect ratio of the image
correctly. The Keep Proportion lock is automatically turned on when you enter
values in either the Scan Frame settings or the Output settings.

Transform
The Transform command allows you to rotate and / or flip the image in
increments of 90 degrees.
The effects of the Transform command will be seen in the Prescan image or are
after you click the Scan button and scan the image in; the Transform effect is
not shown in the Overview viewing mode.
To use the Transform command:
1. Click the Transform button in the Settings window.
2. From the options that appear, choose the degree of rotation you wish.
3. Click the Scan button in the Preview window. When the image is scanned,
it will be rotated or transformed according to the selected option.

Image Category
The image category function in ScanWizard Pro applies predefined settings to
your image and brings out characteristics specific to that image type. This is
helpful in providing a more accurate output image.
To select the correct image category, go to the Settings window and choose the
option you wish from the Image Category menu. Select the image category that
corresponds most closely to the image characterstics of your original.
• None: No image category conversion.
• Standard: Used for an image not falling into any of the categories described
below. You can also use this category for images of good quality (neither
underexposed nor overexposed, with accurate color and tones).
• Landscape: Used for images with cool atmosphere with broad tonal varia-
tion and a wide hue range. Examples: Natural scenery; skyline with an
expanse of blue sky; mountains and fields.
• Portrait (Skin Tones): Used for images with dominant skin tones and mid-
tone details present. Examples: Portraits and objects with fleece- or skinlike covering.
• Jewelry (Gold Tones): Used for images featuring dominant gold / silver
hues. Examples: Gold and silver jewelry, silverware.
• Sunsets: Used for images with warm reddish hues or a color cast reminiscent of sunsets. Examples: Scenes at dusk or twilight.
• Metallic Subjects: Used for images with broad highlight and shadow details
but with very narrow mid-tone details. Examples: Audio equipment,
Cameras.
68 Microtek ScanWizard Pro for Mac OS X
Page 75
• High Keys: Used for images with broad highlight tonal variation but with
less shadow detail. Examples: Snow-covered landscapes; wedding gowns.
• Low Keys: Used for images with broad shadow tonal variation but with less
highlight detail. Examples: Nighttime scenery; dark suits and clothing.
• Underexposed: Used for images with compressed tonal variation particu-
larly in the shadow areas, characterized by an overall dark appearance
typical of underexposed positive film.
• Overexposed: Used for images with compressed tonal variation particularly
in the highlight areas, characterized by an overall bright appearance typical
of overexposed positive film.
In the example below, an
overexposed original is shown in two
different image categories. Because
the original was overexposed to
begin with, choosing the
Overexposed image category had
the result of neutralizing the
exposure, resulting in a better image.
The same original did not fare as
well when it was assigned the
Image assigned “Standard” image category
Standard image category (too bright
overall, not enough contrast),
because this image category is best
used for originals of fairly good
quality (sharp, neither underexposed
nor overexposed) and not, in this
case, for an original with flawed
exposure settings.
This example then shows the
importance of choosing the correct
image category that corresponds
most closely to your original to obtain
optimal results.

Advanced Image Correction Tools
The Advanced Image Correction (AIC) tools form an integral part of
ScanWizard Pro. With the AIC tools, you can adjust or enhance images right
from within ScanWizard Pro and preview the changes to your image even
before you scan.
Before we go to the use of the AIC tools, we will briefly discuss the LCH color
model, which is important for working with images in ScanWizard Pro.This is
followed by other information relating to the LCH model, including the
availability of the AIC tools in LCH vs. Native color mode, and
recommendations on a workflow for optimizing images.
The following topics are covered:
• The LCH Color Model
• AIC tools in LCH vs. Native Mode
• AIC tools and your image type
• Workflow for optimizing images
• How to access the AIC tools
• Elements of the AIC dialog box
• The Action buttons
• Using Custom Settings
• Discussion of the individual AIC tools
70 Microtek ScanWizard Pro for Mac OS X
Page 77
The LCH Color Model
One of ScanWizard Pro’s strengths is its ability to let you work in the LCH
color space. Unlike the RGB color model, which corresponds to the color space
as defined in monitors and printers, the LCH color model is a more intuitive
way of working with colors, based on the values of Lightness (the “L” in LCH),
Chroma (C), and Hue (H). For instance, if you wish to change the color of the
sky in an image to a darker blue, your own eye — and your own judgment —
will be the guide to making those color changes. This is easier than, say,
knowing the mathematical equivalent in RGB or CMYK values that would
correspond to a “dark sky blue”.
The LCH model, in effect, makes it easier to comprehend colors as they are
couched in the terms we are familiar with: Lightness (how dark or light a color
is), Chroma or saturation (how rich or dull a particular hue of green is), and
Hue (the property that distinguishes, say, the color red from the color blue.)
In the LCH color model, colors of equal brightness lie on a single plane of the
model, as shown below. Red and green lie opposite each other on the horizontal
axis, as blue and yellow lie opposite each other on the vertical axis.
On the color sphere shown below, you can see how the different LCH properties
play out:
• The different hues (red, green, yellow, blue) are spread around the sphere.
• The chroma (saturation) for each hue increases from the center of the sphere
outward, with the most saturated colors lying on the edge of the sphere.
• The brightness values increase from the bottom of the model to the top.
Reference: The Advanced Image Correction Tools 71
Page 78
AIC Tools in LCH vs. Native Color Mode
All the AIC tools are available when you work in the default LCH color space,
but a different set of tools is available when you choose to work in the Native
color space. As discussed in an earlier section of the manual, you can select the
color space of your choice in the Preferences menu | More... command in the
Preview window.

Default button
This button restores all settings to their default ScanWizard Pro values.
Revert button
This button cancels out the changes that were made with the current imageenhancement tool. This means that if you used several AIC tools, Revert
cancels the effect of only the last used (or current) tool, and preserves the
effects of the other preceding tools.
Example: If you changed the tone curve, applied filters, changed saturation,
then clicked Revert, the saturation changes will be cancelled out, but the altered
tone curve and filters settings remain in effect
Cancel button
This button cancels out all image-enhancement changes you have made to the
current scan job, and then closes the AIC dialog box.
Example: If you applied filters, changed the curve, and then clicked Cancel,
none of the changes will take effect, and you exit the AIC dialog box.
OK button
This button applies to the current scan job whatever image enhancements you
have performed, and then closes the AIC dialog box.

Gradation tool (LCH color mode)
The Gradation tool lets you adjust the midtones (the mid-level grays) of the
lightness channel “L” of an image without altering the color itself. This is
because even with changes to the luminance or lightness value, the chroma and
hue values are kept constant.
To prevent color images from losing saturation when adjusting the lightness,
ScanWizard Pro provides a Saturation Range option. With this option, colors
outside of a given chroma range are not affected by the manipulation of the
gradation curve.
The Curve shows the relationship of
the brightness changes across the
middle pixels between the resulting
image and the original. When you
open the Curves dialog box, the line
on the graph is diagonal because the
Input and Output values are the
same.
When the curve is moved up or
down, the relationship between input
value and output value changes
accordingly.
•In areas where the curve is
moved down, pixels in that
portion of the image are
darkened.
•In areas where the curve is
moved up, pixels in that portion
of the image are lightened.
Contrast in an image can be seen by
the angle of the line. The steeper the
slope, the higher the contrast. The
closer the line is to horizontal, the
lower the contrast.
