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.
