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

specific label/ribbon combination and print speed.

“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.
