How to Prep Your Files For Apparel Printing

How to Prep Your Files For Apparel Printing

A simple guide to getting your artwork print-ready for apparel.

When it comes to printing apparel, the quality of your file determines the quality of your final product.
Clean lines, sharp edges, bold shapes — these details carry your brand.
The better the file, the better your print.

Here’s a straightforward guide to preparing artwork for DTF apparel printing so your logo shows up exactly the way you imagined.

1. Use vector files whenever possible

Vector files are the gold standard for printing.
They scale without losing quality, which means your logo stays crisp whether it’s on a chest print or a full-back design.

Preferred formats:
.AI
.EPS
.SVG
.PDF (vector)

If your designer used Illustrator, you’re on the right track.

2. If you’re using raster images, go high-resolution

Sometimes all you have is a PNG or JPG, and that’s fine — as long as it’s high-quality.

For apparel printing, aim for:
300 DPI
At the exact size you want it printed
No blurry or pixelated edges

A logo pulled from a website or screenshot won’t cut it.
Those files break down fast.

3. Avoid tiny text and thin details

DTF prints cleanly, but it still has physical limits.
Small lettering and thin strokes can get lost, fill in, or lose clarity when transferred onto fabric.

A good rule of thumb:
If you can’t read it clearly at 100 percent size on your screen, it won’t read on a shirt.

Go bold. Go simple.
Your future self will thank you.

4. Use solid colors and clean edges

Feathered edges, subtle gradients, and low-contrast details don’t reproduce well in DTF.

To get the best results:
• Choose clear color boundaries
• Use solid fills or high-contrast gradients
• Remove soft shadows, glows, or fuzzy effects

The cleaner the file, the cleaner the print.

5. Make sure your background is transparent

For most apparel prints, you want a transparent PNG or a vector file with no background.

This prevents unwanted boxes, halos, or color blocks from appearing around your design.

If you’re not sure, open your file on a checkerboard background — if you see white where you shouldn’t, the background needs to be removed.

6. Keep your colors simple and intentional

More colors isn’t always better.
In apparel printing, clarity beats complexity.

Stick to:
• High-contrast color combinations
• Simple palettes
• Bold shapes

Your logo carries more power when it reads clearly at a glance.

7. When in doubt — send it early
