Figure 30 • Bar Code Darkness Comparison
Table 16 • 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.
