Scanning from the TWAIN Interface

66 DocuMate 515 Scanner User’s Guide

Adjusting the Resolution

Resolution determines the amount of detail you can see in the scanned

image. The resolution setting for a scan is in dots-per-inch (dpi). The

higher the resolution, the finer the details. However, higher dpi settings

also take longer to scan and produce larger file sizes. For black and white

documents, 150 dpi will make a copy of similar quality to the original. If

you are scanning photographs to make copies, 300 dpi will make a direct

size copy of similar image quality to the original. You would use a higher

dpi setting to enlarge a picture from the original size.

To adjust the resolution:

1. To use one of the preset resolutions for typical scanned items, click

one of the options in the list.

2. To set the resolution manually, drag the Resolution slider to the left

to decrease the resolution or to the right to increase it.

3. Click Reset to return the resolution to its original setting.

The resolution panel also includes an advanced setting for Moire

patterns. Moire patterns are wavy, rippled lines that sometimes appear on

the scanned images of photographs or illustrations, particularly

newspaper and magazine illustrations. To scan the image and limit or

eliminate moire patterns, select the Reduce Moire option. This option is

not available for high resolution settings.
