Too dark labels |
Fairly obvious. These may be readable but are not “in-spec.” The normal barcode bars increase in size. The openings in small alphanumeric characters may fill in with ink. Rotated barcode bars and spaces run together.

Slightly dark labels |
Not as obvious as the too-dark labels. The normal barcode will be “in-spec.” Small alphanumeric characters will be bold, and may appear slightly filled in. The rotated barcode spaces are small when compared to the “in-spec” code, possibly making the code unreadable.

“In-spec” labels |
Whether or not a label is “in-spec” can only be confirmed by a verifier, but they typically exhibit some visible characteristics. The normal barcode will have complete, even bars along with clear, distinct spaces. The rotated barcode will have complete, even bars along with 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 will look complete.
|
Slightly light labels |
In some cases, these are 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 |
Both normal and rotated barcodes have incomplete bars and spaces. Small alphanumeric characters are unreadable.
