Judging image Quality
When you look at your monitor to evaluate a scanned image,
remember that the image will look different when it is printed.
A monitor is a comparatively low-resolution device; some
images that look good on a monitor do not look as good when
printed and vice versa. Keep in mind the final output device as
you choose settings and manipulate the image.
In addition, each output device may produce different results.
A proof printed on an electronic color printer will look different
from the same image printed on a printing press.
Equipment
Your present equipment may be sufficient for your scanning
needs, but if you are not satisfied with the quality of the
images on your monitor or with the speed of image processing,
read this section. While it does not contain specific
recommendations, it describes various possibilities for
improving your scanning system. For further information, see
your dealer or an experienced scanner user.
RAM and hard disk size
Scanned images can use much more memory than text files, so
you may need more Random Access Memory (RAM) in your
computer and a larger hard disk than you have used previously.
Accelerator boards
In addition to memory, processing speed is important because
large files take longer to process than small ones. Therefore,
you may want to add an accelerator board to your computer.
