Why Packaging Artwork Gets Rejected in Prepress

Most artwork problems are preventable: missing bleed, low-resolution images, RGB color, live fonts, incorrect dielines, and unsafe barcode placement. This guide explains how to prepare files before production review.

01

The problem, framed.

Prepress rejection is the most preventable delay in packaging. The file looked perfect on a designer's screen — and still can't be printed. Almost every rejection traces to a handful of repeat offenders.

02

What's actually going on.

Production artwork has requirements screens never enforce: vector die lines on a separate top layer set as spot-color overprint, fonts converted to outlines, images embedded at 300+ DPI at 100% scale, CMYK color mode with Pantone callouts for brand-critical color, 0.125-inch bleed beyond the die line and the same safety margin inside it. Miss one and the file bounces.

03

How to decide.

01Get the production die line before design starts, not after it ends.
02Build in CMYK from day one — RGB conversion at the end shifts color.
03Outline fonts and embed images as the final save step, every time.
04Run the artwork checklist before submission, not after rejection.
04

Common mistakes.

Designing on a guessed canvas size instead of the real die line.
72 DPI web images scaled up to fit a panel.
Live fonts that substitute on the prepress workstation.
Critical text drifting into the gusset fold or seal zone.
