Placement
Typically, barcode placement should be on the lower right quadrant of the back of the product.
Barcodes should be...
In the same locations as all similar shaped products
On a flat surface or consistently curved surface
(On small cylindrical products) Positioned vertically ensuring curvature of the product doesn’t make the product difficult to scan
Never position the barcode on an area with inadequate space
Never place barcodes (including Quiet Zones) on perforations, die-cuts, seams, ridges, edges, tight curves, folds, flaps, overlaps and rough textures
Never fold a symbol around a corner
Never place a symbol under a package flap
