Packaging errors are expensive to fix after the fact — a die-line mistake or wrong bleed can mean scrapping an entire print run.
Why this list exists
Before any packaging file goes to press, our production team checks it against a fixed list: bleed and safe margins, die-line accuracy against the physical mould, colour mode (CMYK, not RGB), resolution of embedded images, font outlining, barcode scannability, and structural fold tolerances.
The most common reprint cause we see is a die-line that was resized in design software without updating the fold and glue-flap proportions — which looks fine on screen but fails to fold correctly on the physical board.
If you're designing packaging in-house, ask your printer for the exact die-line template before you start; it saves at least one full revision cycle.
