Whether you’re producing uniforms, brand tees, or activewear collections, digital garment printing offers the flexibility and speed that traditional methods often can’t. But here’s the catch, no matter how advanced the print technology is, it can’t fix a bad file.
From resolution issues to missing layers, simple errors in your artwork can lead to poor results or even a failed print run. When you’re printing hundreds of pieces, even the smallest issue becomes expensive. In this article, we’ll break down the most common mistakes we see in print file setups, and how you can prepare your artwork the right way for digital garment printing.
Why Print File Setup Matters More in Bulk Orders
In small runs, it’s possible to stop and fix a print mid-way if something’s off. In bulk t-shirt printing, every second counts, and consistency is key. If your print file isn’t 100% correct from the start, the same error will appear on every single shirt. That’s hundreds of flawed prints, wasted materials, and potentially missed deadlines.
With digital garment printing, especially with technologies like DTG or DTF, your file is the blueprint. It tells the printer how to layer colors, where to apply white ink, and how sharp the design should be. If the blueprint is wrong, so is the outcome.
Most Common File Mistakes in Bulk T-Shirt Printing
1. Low-Resolution Files
Blurry images don’t magically become sharp when printed. Many clients submit files that are under 150 DPI, which results in a loss of detail. For digital garment printing, we always recommend at least 300 DPI at print size.
2. Incorrect Dimensions
If your file is set to A4 size but you want a chest-wide print, the design may be stretched or printed too small. Always create your artwork at the actual size it needs to be printed. If you’re unsure, check with your printer for standard size templates.
3. RGB vs. CMYK
Digital screens use RGB, but most digital printers work best with CMYK. Submitting RGB files can lead to color shifts. If your brand color is important (which it always is), converting to CMYK and soft-proofing the result is a must.
4. Missing Transparent Backgrounds
For prints on colored garments, white boxes around your design are not a good look. Your artwork should come with a transparent background if it’s not meant to be a full-rectangle image. PNG files with transparency or layered PSDs work best.
5. Fonts Not Outlined
When working with vector files like AI or PDF, missing fonts can be a hidden issue. If your printer doesn’t have the font installed, the design might auto-replace it. Always convert your text to outlines or embed the font.
How to Prepare Print-Ready Artwork for Digital Garment Printing
So, what should a clean, ready-to-go file look like for digital garment printing?
Start with a canvas that matches your intended print size and use 300 DPI resolution. Work in CMYK color mode and keep layers organized. Use high-quality PNG, PSD, or vector formats when possible.
If you’re unsure about bleed, safe zones, or sizing, many printers (including In-Credible) offer downloadable templates. These give you a foolproof framework to work within.
And if you’re producing multiple SKUs (say, different shirt colors), it’s important to adjust your design for each background color. DTF and DTG both require adjustments in how underbase (white ink) is applied.
