Figure 5 • Bar Code Darkness Comparison

Table 8 • Judging Bar Code Quality

Print Quality Description

Too dark Labels that are too dark are fairly obvious. They may be

readable but not “in-spec.”

• The normal bar code bars increase in size.

• The openings in small alphanumeric characters may fill in

with ink.

• Rotated bar code bars and spaces run together.

Slightly dark Slightly dark labels are not as obvious.

• The normal bar code will be “in-spec.”

• Small character alpha numerics will be bold and could be

slightly filled in.

• The rotated bar code spaces are small when compared to

the “in-spec” code, possibly making the code unreadable.
