Video cards
A video card that is sufficient for text may not be good enough
for displaying graphic images, especially in color. If all your
scanned images look coarse on your monitor, you may want to
upgrade your video card. You will need 24-bit color, also called
true color or millions of colors, to make the highest quality image
reproductions.
Monitors
The resolution of your monitor affects the quality of the image
you see. Consider a high resolution monitor if you do precise color
work, but also be sure you have a high quality video card.
File compression software
Many different programs are available to make image files
smaller for storage or transmission. For example, some
compression software can store a 3MB image file on a 1.44 MB
floppy disk, and compress images and restore them with no loss
of data or quality; others compress images more, but the restored
file is not exactly the same as the original. The difference between
the original and restored files is, however, almost unnoticeable.
