On-line graphics: If you are scanning an image to be used orim-line, such as the Internet, a
BBS or in a multimedia presentation, you ne,odn’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.
Faxing images: Any image you intend to fax from a PC-based fax modem should be
scanned at 200 dpi. Fax machines only receive images at 200 dpi, and some programs
may fault if you try to scan at higher resolutions.
Printed images: If you plan to print the images you scan, use the following table to select a
resolution when scanning in color and gray scale. As a general rule, scan at twice the Line
Screen Frequency of the output device. This information can be found in your printer’s
manual. When scanning in line art mode, scan at the resolution of your printer, usually
300 or 600 dpi. This avoids sizing distortions in your printed images.
