	Table 8 • Judging Bar Code Quality (Continued)
Print Quality		Description
“In-spec”		The “in-spec” bar code can only be confirmed by a verifier,
		but it should exhibit some visible characteristics.
		• The normal bar code will have complete, even bars and
		clear, distinct spaces.
		• The rotated bar code will have complete, even bars and
		clear, distinct spaces. Although it may not look as good as
		a slightly dark bar code, the bar code will be “in-spec.”
		• In both normal and rotated styles, small alphanumeric
		characters look complete.
Slightly light		Slightly light labels are, in some cases, preferred to slightly
		dark ones for “in-spec” bar codes.
		• Both normal and rotated bar codes will be in spec, but
		small alphanumeric characters may not be complete.
Too light		Labels that are too light are obvious.
		• Both normal and rotated bar codes have incomplete bars
		and spaces.
		• Small alphanumeric characters are unreadable.

5.Note the relative darkness value and the print speed printed on the best test label.

6.Add or subtract the relative darkness value from the darkness value specified on the configuration label. The resulting numeric value is the best darkness value for that specific label/ribbon combination and print speed.

7.If necessary, change the darkness value to the darkness value on the best test label.

8.If necessary, change the print speed to the same speed as on the best test label.
