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.
