Print-Ready Artwork Guide for Packaging

The single biggest cause of production delays we see isn’t material shortages or scheduling — it’s artwork that isn’t actually print-ready when it arrives. Here’s a practical checklist to catch the common issues before they cost you a reprint cycle.

Start From the Dieline

A dieline is the flat, unfolded template showing exactly where your box will fold, cut, and glue. Always design on top of the dieline we provide for your exact box style and size — designing to approximate dimensions and hoping it lines up almost never works cleanly.

Work in CMYK, Not RGB

Screens display color in RGB; printing presses lay down ink in CMYK. Colors that look vibrant on a monitor — especially bright blues, greens, and purples — can shift noticeably when converted to CMYK for print. Design and proof in CMYK from the start to avoid surprises.

Set Resolution to at Least 300 DPI

Images and logos placed at web resolution (72 DPI) will print visibly soft or pixelated at box scale. Every raster element should be at least 300 DPI at final print size — check this before submitting, not after seeing a blurry proof.

Include 1/8 Inch (3mm) of Bleed

Any color or image that’s meant to run to the edge of a panel needs to extend at least 1/8 inch (about 3mm) past the trim line. Without bleed, small variances in cutting can leave a thin white sliver along the edge of an otherwise perfect design.

Keep Critical Content Inside the Safe Zone

Text, logos, and barcodes should stay at least 1/8 to 3/16 inch (3–5mm) inside the trim edge and well clear of fold lines, where they can be distorted or partially obscured. This is especially important near corners and glue flaps.

Flatten and Outline Fonts

Submit fonts as outlines (converted to paths) rather than live text whenever possible. This eliminates font-substitution issues if the exact typeface isn’t installed on the printing side, and it’s standard practice for production-ready files.

If any of this feels like a lot to manage, we check every file before it goes to press and flag any issues before production — and our design team can build print-ready artwork from scratch if you don’t have finished files yet.
