File Preparation Guide for Custom Packaging

Get your artwork ready for print production with our precise standards. Follow these clear technical guidelines to ensure your custom boxes, sleeves, and labels print with sharp detail and exact color matching.

Introduction to Print-Ready Files

Submitting a production-ready file saves your brand time and prevents unexpected printing errors. When you order custom packaging from us, our pre-press team reviews your layout to guarantee structural accuracy. However, uploading artwork that matches our technical specifications ensures your text stays sharp, your colors match your brand identity, and your boxes fold cleanly without edge distortions.


01

Preferred File Formats

Vector-based file formats are essential for packaging print production. Vectors allow your logos, lines, and text to scale infinitely without losing resolution or showing pixelation.

Adobe Illustrator (.AI or .EPS)

The industry gold standard. Please ensure all text elements are converted to outlines (paths) and linked images are embedded.

High-Resolution PDF (.PDF)

Export your files using the "High Quality Print" or "PDF/X-1a" preset with crop marks and bleeds included.

Note on Raster Files (.JPG, .PNG): While acceptable for photographic elements on packaging, raster images must be supplied at a minimum resolution of 300 DPI at actual print size to avoid blurry prints.
02

Color Modes: CMYK and Spot Colors

Computer monitors display colors using the RGB (Red, Green, Blue) spectrum, whereas physical printing presses print using CMYK (Cyan, Magenta, Yellow, Key/Black) inks.

  • Set your color space to CMYK: Designing in CMYK prevents unexpected color shifts between your digital preview and the physical box.
  • PMS (Pantone Matching System): If your brand identity requires an exact color match across different production runs, please specify your exact Pantone solid coated color codes.
03

Bleed, Trim, and Safe Margins

During high-speed die-cutting and trimming, minor mechanical shifts can happen. Proper layout lines protect your artwork from getting clipped or leaving unprinted white edges.

Bleed Area (0.125" to 0.25")

Extend background colors and patterns past the cut line to prevent white borders.

Trim Line

The exact boundary where your custom box or sleeve is cut out by the manufacturing die.

Safe Margin (0.25")

Keep all essential text, logos, and critical design elements safely inside this boundary.

04

Typography and Embedded Assets

Missing font files are the primary cause of production delays. When fonts are not converted or embedded, our systems substitute them automatically, which alters your layout.

  • Create Outlines / Convert to Curves: Select all text layers in your vector editing software and convert them to shapes before exporting.
  • Embed Linked Images: Ensure external graphics are embedded directly into your working document file rather than linked via file paths.
