Bar Code Print Settings
To achieve the best quality printing and improve the readability of the bar code, use the K
(black) panel of the color ink ribbon to print the black bars. Bar codes printed with the color
panels may not be as crisp and sharp as those printed with the K panel only. Refer to the
documentation for your card personalization software for more information about how to
print bar codes using the K panel.
Infrared readers require that the K panel be used to print the bar code.
Test Bar Codes
Always test the readability of bar codes under production conditions. Factors to consider include:
If you print cards one at a time, print the samples using that method. If you print cards in
batch (many cards sent to the printer at the same time), use a production-sized batch and
evaluate cards from the beginning, middle, and end of the batch.
Use exactly the same card stock for testing that you use for production. The card stock can
affect the readability of bar codes. Usually, a white surface that reflects light in many
directions is needed. Test cards before purchasing production quantities.
Include other card design components that you use in production.
Use the same bar code readers that users have, and test each card multiple times. Also test
multiple cards.
Card Design Changes That Affect Bar Codes
If you make substantial changes to the way you produce cards, review your setup tasks to make
sure that cards continue to have the quality you require.
The following production changes can change the color of some images and can affect bar codes:
Purchasing a new brand of card stock
Changing to, or from, preprinted cards
If you change the design of your cards, or if you start producing an additional card design, test
each design as described in
44
"Test Bar Codes"
to make sure that the bar code prints as expected.
