Introduction
Kodak’s low volume production scanners include image processing
technology that can improve image quality and sometimes make the
reproduction better than the original.
Kodak Digital Science
You can use the ISIS driver or TWAIN Data Source (both are available
on the CD that is included with the scanner) or
Low Volume Capture Software to enable image processing.
Many popular scanning applications are also compatible with these
scanners. However, other scanning applications may not be able to
access any or all of the image processing options.
Not all image processing features are available for each scanner or
each driver. Refer to the table on the following page for the features
available for each scanner.
NOTE: The scanned images used in this guide were selected for the
challenges presented to a typical scanner due to the lowcontrast characteristics of the images.

Memory Requirements
The Scanner 1500 and the Scanner 2500 both have 8 MB of memory
already installed. This may be sufficient for your scanning needs.
Additional memory may be required, depending on the selected
resolution and paper size. You may add up to 64 MB more memory on
SIMM modules for a total of 72 MB. (Memory is available in 8, 16, or 32
MB modules. Obtain memory at a local retailer.) Up to two SIMM
modules can be installed for the required extended memory. Refer to
the scanner’s User ’s Guide for infor mation about installing memory.
The tables below and on the following page show how much memory
(in MB) you would need to add to scan a particular paper size at a
given resolution. (“0” means that no additional memory is required.)

scanning time and memory.

Dither
Dithering is a technique for reproducing halftone images, such as a
photo, in binary mode.
Two pixel levels are used to represent the entire grayscale, thereby
reducing the levels of gray required displaying an image. Using a
dithering pattern requires less memory than using a grayscale mode.
Choose a dithering method in the Dither drop-down list box: None,

Dots per inch (Resolution)
Dots per inch (dpi) indicates the scanning resolution, which largely
determines the quality of the scanned image. The greater the
resolution, the better the reproduction. However, scanning at a higher
resolution also increases scanning time and file size. This function sets
the resolution of the main scan and sub-scan areas. The industry
standard is 200 dpi (about 8 pixels/mm).
Page Size
You can choose a preset resolution value in the
down list box or type the desired value. The default value is 300 dpi.
Following are the available resolutions:

• Scanner 2500—100-600 dpi (1 dpi/step)

Contrast
The Contrast option sets the image contrast by adjusting the difference
between black and white, thereby making an image sharper or softer.
In a low-contrast setting, the difference between black and white is
small, so the image is softer. In a high-contrast setting, the difference
between black and white is large, so the image is clearer. Select a
contrast value from 1-255. The default is 128.

Compression
Scanned image data can be compressed to decrease file sizes. When
Compression is specified, files transmitted from the scanner decrease
in size, thus allowing more images to be stored on the host PC.
Select a compression type in the
Document Name dialog box.
Compression cannot be used for some applications or image file
formats. For example, you cannot use Compression for the bitmap
format (*.bmp) used by Windows. Choose a compression form that is
compatible to the one your application supports.
The following compression methods are available:
• CCITT-G3—an old version of the CCITT compression standard
which should be used only with older imaging systems. This can
be used only for bitonal images.
• CCITT-G4—the current industry standard. This can be used only
for bitonal images.
Compression
box in the Scanned
• JBIG—has a high compression rate for bitonal and grayscale
images and significantly better compression rate for dithered
images in comparison with CCITT-G4. However, JBIG does not
have the same industry acceptance as CCITT-G4.
NOTE: For documents composed almost entirely of photographs
scanned by Dither using G3 and G4 compression, the
compressed file may be larger than the uncompressed file.

Resolution (DPI)
A-63055 December 1999 43
Resolution or dots per inch (dpi) indicates the scanning resolution,
which largely determines the quality of the scanned image. The
greater the resolution, the better the reproduction. However, scanning
at a higher resolution also increases scanning time and file size. This
function sets the resolution of the main scan and sub-scan areas. The
industry standard is 200 dpi (about 8 pixels/mm).
You can choose a preset value in the Resolution box or type the
desired value. The default value is 300 dpi. Following are the available
resolutions:
• Scanner 1500—100-600 dpi (1 dpi/step)
• Scanner 2500—100-600 dpi (1 dpi/step)

Halftone (Dither)
Dithering is a technique for reproducing halftone images, such as a
photo, in binary mode.
Two pixel levels are used to represent the entire grayscale, thereby
reducing the levels of gray required displaying an image. Using a
dithering pattern requires less memory than using a grayscale mode.

darker the image. Or you can type a value (1-255) in the Brightness

Contrast
The Contrast option sets the image contrast by adjusting the difference
between black and white, thereby making an image sharper or softer.
In a low-contrast setting, the difference between black and white is
small, so the image is softer. In a high-contrast setting, the difference
between black and white is large, so the image is clearer. Select a
contrast value from 1-255. The default is 128.

This feature detects the following paper sizes: Legal, Letter, A3, A4,
A5, A6, B4, B5, and B6.
Set documents of different sizes on the left side of the feeder. The
scanner detects the document size by the document guide positions.
When Detect Double Feed is enabled, multiple feed documents (two
or more documents scanned simultaneously) will be detected.

Document Printer (Imprinter)
The Imprinter button in the Scanner Special Features dialog box
allows you to access the Imprinter Parameters dialog box in which you
can set up parameters for the optional document printer. The
document printer can print character strings on a document.
There are two printing methods:
• Pre—prints on the front of the document before scanning.
The printing becomes part of the scanned image.
(Available for the Scanner 1500 and the Scanner 2500.)
• Post—prints on the back of the document after scanning.
The printing does not become part of the scanned image.
(Available only for the Scanner 2500.)

The chart below shows the characters that the document printer can
print on the scanned document.
