more but dramatically increase the file size, take up more disk space, and
slow down the process.
Internet Applications: For e-mailing color photos or pasting images on Web
sites, a resolution of 100 dpi is the best choice. This is because the actual
viewable resolution of the average monitor is 72 dpi. Additionally, download
times are dramatically reduced.
Printing to Ink Jet Printers: Check your printer documentation for
recommended printer resolution settings. We recommend ranges between
75-300 dpi in general. Only use a higher scanning resolution (300 dpi and
above) for smaller images when detail must be captured in a small area
because it will be enlarged later.
Laser and Commercial Printers: When printing an image to a laser printer or
commercial printing press, it is important to understand the process in terms
of line screen (a.k.a., LPI). Line screens are the number of screen lines per
inch when an image is half toned. Half toning is the process of breaking the
image down into a series of dots to reproduce continuous-tone art when
printing on a press. A general rule when printing in one of these two manners
is to scan one and a half to two-times the amount of the line screen. Laser
printers that have resolution ranges of 300 and 600 dpi will have line screens
between 50 and 100. Typical commercial printing is done at an average line
screen of about 150. Therefore, an optimal scanning resolution would be 200
or 300 dpi.
