8 - 18 USING YOUR MACHINE WITH A MACINTOSH

Color Type

Black & White—Set the image Type to Black and White for text or

line art. For photographic images, set the image type to Gray (Error

diffusion) or True Gray.

Gray (Error Diffusion)

—is used for documents that have

photographic images or graphics. (Error Diffusion is a method for

creating simulated gray images without using true gray dots. Black

dots are placed in a specific pattern to give the appearence of gray.)

True Gray

—is used for documents with photographic images or

graphics. This mode is more exact because it uses up to 256 shades

of gray. It requires the most memory and takes the longest transfer

time.

Colors

—Choose either 8-bit Color, which scans up to 8-bit Color or

24-bit color which scans up to 16.8 million colors. Although using

24-bit color creates an image with the most accurate colors, the

image file will be about three times larger than a file created with 8-bit

Color.
