24 Elements of Card Design
Print Bar Codes
Bar code design follows a set of standards based on the type of bar code produced. Bar codes
contain a series of black lines (bars) separated by white areas (spaces). Each character of encoded
data is represented by a set of bars and spaces. A bar code standard specifies the number and
width of bars and spaces needed to encode a character. The standard also specifies the minimum
size of the white area, or quiet zone, that surrounds the bar code.
Bar Code Guidelines
Bar codes print more successfully when you observe the following guidelines. Follow the
standards for the type of bar code you are printing.
Bar Code Placement
Maintain the required quiet zone around the actual bar
code, as shown in the illustration.
Locate bar codes at least 0.25 inch (6.3 mm) from other
printing and from the edge of the card.
For best results, orient the card so that the bars are parallel
to the long edges of the card, as shown. This orientation
most accurately prints readable bar codes.
Refer to “Print Bar Codes With the Card Printer Driver” on page 26 for information
about how to use the Card Printer Driver to improve the probability that a bar code
prints using the K panel.
