Figure 19 • Bar Code Darkness Comparison
Table 20 • 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.
