“In-Spec” The “in-spec” barcode can only be confirmed by a verifier, but it should exhibit
some 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.
