RGB Color: Scan color images and photographs in RGB Color mode

when you want to capture and reproduce all the color data. To manage

file sizes efficiently, take careful note of the guidelines for resolution

(described later) when scanning in RGB. The combination of RGB Color

and a high dpi can create an extremely large file size, as well as take

several minutes to scan.

Gray Scale: What is referred to as black and white photographs are

actually gray scale images. Different shades of gray are used to make

up the whole picture. When you scan these types of images, you want

to scan using the gray scale mode. Also use this mode to convert color

photographs to black and white. Scanning a color photograph in gray

scale will capture the continuous tones.

B/W: This mode captures black and white only. Use this mode when

scanning single color (usually black) images, such as drawings or

sketches, business logos, or text.

          Resolution

Resolution is measured in dots per inch (dpi). The higher the resolution

is set, the more detail in your image is captured. There are some

guidelines you should follow when determining the resolution to

scan at..

On-line graphics: If you are scanning an image to be used on-line, such

as the Internet, a BBS or in a multimedia presentation, you needn’t

scan any higher than 100 dpi. This is because a monitor’s resolution is

either 72 dpi (Mac), or 96 or 120 dpi (PC), and is not capable of

displaying a higher resolution. Images scanned at 300 dpi and viewed

on a monitor will appear three times as large as the actual image. This

enlargement results because your monitor displays images in a 1:1 ratio

of pixels (or dots), meaning one dot in the image equals one dot on-

screen. At 300 dpi, the image contains 3 times as many dots when

displayed on the monitor.

Printed images: If you plan to print the images you scan, set the

scanning resolution no higher than equal to the resolution of your

printer, typically 300 dpi or 600 dpi. This will avoid sizing distortions in

your printed image.
