Scanning Tips 
 
 
 
Scan photos instead of printed pictures 
 
Images from magazines or books are composed of tiny dots. The typical resolution for color 
typesetting is 180 or 300 dpi, so scanning at higher resolutions offers no advantages. As a 
matter of fact, higher resolutions may even be worse because the scanner often sees white 
dots in between the printed color dots. To preserve accurate toning details, if possible, scan 
photographs instead of printed materials. 
 
Scan good quality images and text 
 
You always lose some information when you scan. By carefully choosing your images and 
settings, you can minimize this problem. For example, don't try to scan extremely light or 
dark images or those with very low contrast. 
 
Limit the image size when possible 
 
Small images require much less hard disk space and processing time than large ones. Be 
aware of how much disk space you have on your system when you acquire your pictures. If 
your available disk space is limited, you may only be able to copy a few photographs to your 
camera or computer.
