Printing or display methods
The best resolution to use depends on what type of output or
printing method you will be using. The usual printing methods
for scanned images fall into the following categories:
❏
Black and white printers (laser, inkjet, or dot matrix) are good
to excellent for text and line art but are not as good for
grayscale images. These printers can be used for
reproducing photographs in documents like newsletters that
do not require the highest quality.
❏
Electronic color printers use laser, ink jet, or other technologies
to produce color or grayscale images that range from
coarsely patterned to nearly photographic (often called
continuous tone) quality. It is best to see samples from a
color printer before you decide to use it. These printers are
usually used for small quantities of color images or for
preliminary proofs of images that will be printed on a
printing press.
❏
Printing presses are for high quality and high volume work.
You scan and edit your images and then send the files to a
service bureau or printing company, which uses high
resolution phototypesetters (also called imagesetters) for
high quality text and grayscale images. For full-color images,
you scan in color and then use your image editing software
to manipulate the image and produce color separation files.
If you plan to do this, see the guidelines below on resolution
and then follow the instructions in your software manual for
making separations. Your service bureau or printing
company should also provide helpful information.
