Advanced Scanning
Note:
Resolution in
professional printing is
measured in lines per
inch (lpi), rather than
dots per inch (dpi).
The best resolution for a scanned image depends on
the type of image you are scanning and your final
output device. The following table shows the best
scanning resolutions for the most common
applications:
Output device
Inkjet printer
Monochrome laser printer
Computer screen
Four-color printing press with 150 lpi
Four-color printing press with 175 lpi
B&W printing press with 85 lpi
B&W printing press with 100 lpi
B&W printing press with 133 lpi
Line art logo
Optical Character Recognition (OCR) 300 dpi
The higher a resolution you select, the larger the
resulting image file. For example, an 8.5 x 11 inch
original scanned at 300 dpi can produce a 24 MB file.
