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.
Bar Code Size

A lower density bar code is easier to read, because the bars are wider and spaced farther
apart.

The width of the narrow elements in the bar code must be large enough to be read
consistently. The capabilities of the bar code reader can influence this.

The bar code must be tall enough to be read under normal conditions.
Bar Code Print Settings

To achieve the best quality printing and improve the readability of the bar code, use the K
(black) panel of color print ribbon to print the black bars. Bar codes printed with YMC panels
are not as crisp and sharp as those printed with the K panel only.

Infrared readers require that the K panel be used to print the bar code.

The ANSI standard for bar code quality (X3.182) assigns a grade to a bar code to indicate its
readability. Choose a K power value and bar code size to produce the grade your system
requires. Refer to “Print” on page 44 for information about setting the K power value.
