A d j u s t i n g t h e P r i n t Q u a l i t y
Many factors affect print quality: type of supplies, print contrast, and the
type of printer's application. The type of supply should match the printer's
application.
¨ Using premium supplies reduces smudged images, hard to read labels,
and faded print. Supply type, print speed, and print contrast work
together to improve the print quality of labels. Contact your Paxar
Representative for more information.
¨ If the print quality is too light or too dark, adjust the print contrast. The
correct contrast setting is important because it effects how well your bar
codes scan and how long the printhead lasts.
Be sure to check the print quality of bar codes with a bar code verifier or
scanner. If you do not have a verifier or scanner, check the bar code
visually. A bar code that is IN SPEC will have complete bars and clear
spaces. Small alphanumeric characters will look complete. A bar code
that is IN SPEC may not look as good as one that is too dark, but it will
have the highest scan rate.
Note: For highest scan rates, make sure there is adequate white space
before and after the bar code. A darker bar code does not mean it
will scan better.
