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