NOTE: Choosing the True Color RGB 36-bit setting captures more data than the 24-bit setting. This
means that the file sizes listed above will be larger if you scanned images using the True Color 36-bit RGB
setting.
Choosing the Best Resolution for Your Scanning Project
To choose the best resolution for scanning, determine what you are going to do with the image once it is
scanned. Matching your scanning resolution to the image use will give you the best image for that purpose
and will keep the file sizes to the minimum needed.

Using Custom Resolution Settings
You can also specify custom resolution settings that you can use when you scan. The maximum custom
resolution setting you can define is 2400 dpi. To define the custom resolution settings:
1. Choose the Custom… option from the Resolution drop down menu. The Custom Resolution window
opens.
2. Enter the desired resolution setting (between 50 and 2400 dpi) in the Custom resolution #1 box.
3. Repeat step 2 to define the Custom resolution #2 and Custom resolution #3 settings.
4. Click OK. The settings you defined appear on the Resolution setting drop down menu, under the
Custom heading.
Changing the Descreen Feature
The Descreen option helps eliminate the patterns that appear when you scan printed images found in
magazines, brochures, catalogues, etc. This is accomplished by changing the number of lines that appear in
every inch (lines per inch) of the scanned image.
The Descreen feature is unavailable when you have chosen the B/W Document, FAX, or OCR resolution
settings.
