8. Note the relative darkness value and the print speed printed on the best test label.
9. 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.
10. If necessary, change the current darkness value to the darkness value on the best
test label.
11. If necessary, change the current print speed to the speed value on the best test label.
“In-spec”
The “in-spec” barcode can only be confirmed by a verifier,
but it should exhibit the following visible characteristics.
• The normal barcode will have complete, even bars
and clear, distinct spaces.
• The rotated barcode will have complete, even bars
and clear, distinct spaces. Although it may not look
as good as a slightly dark barcode, the barcode 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” barcodes.
• Both normal and rotated barcodes 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 barcodes have incomplete
bars and spaces.
• Small alphanumeric characters are unreadable.
