✔Image Type or Mode
For the best and most efficient scans, you need to know which type of images you are scanning: drawings, black and white photographs, or color photographs. The corresponding terms used by scanning software are line art, grayscale, and color.
❏Line art
This is the setting for drawings, including all drawings or pictures made up of black and white only, with no gray tones.
❏Grayscale (also called monochrome or continuous tone) This is the setting for black and white photographs and drawings with various shades of gray in addition to black and white. You can also use this setting for color photographs that will be printed in black and white.
❏Color
This is the setting for color photographs or other originals in color.
Note:
Scans from photographs are better than scans from published images, such as newspaper or magazine pictures, because of halftoning conflicts. Use photographs instead of published images for experimenting with your scanner.
✔Resolution
The best resolution setting depends on the image type or mode (line art, grayscale, or color) and the printing method. Read “Printing or display methods” and “File size” below; then use the table on page
