Advanced Scanning
Page 54
The same original scanned at 72 dpi creates only a 1.3
MB file.
Large files take longer to process and print, so
consider the practical limitations of your computer
system and hard disk drive when selecting a
resolution. To keep file size manageable, select the
lowest possible resolution that gives acceptable
quality.
For Home or Office Output
As a rule of thumb for any image except line art, use
scanning resolutions that are approximately one third
of your output resolution.
For example, use a scanning resolution of up to
110 dpi with a 300 dpi laser printer, and up to 170 dpi
with a 600 dpi laser printer.
For inkjet printers, such as for a 1440 dpi EPSON
Stylus
®
COLOR series printer, use a scanning
resolution of up to 240 dpi.
