When it comes to custom t-shirt printing, your design file is everything.
We love helping our customers bring their ideas to life, but the truth is: the final result is only as good as the file you send us. A blurry, low-resolution, or misaligned design can lead to poor-quality prints—and that’s the last thing we want for you.
Whether you’re creating a design from scratch or uploading existing artwork, this print-ready file requirements guide breaks down everything you need to know about print-ready files and how to set yourself up for success.
🖼️ What Is a “Print-Ready” File?
A print-ready file is a digital design that meets the technical requirements to go straight to production—no edits, no guesswork.
Here’s what we mean by “print-ready” at 24 Hour Tees®:
- ✅ High-resolution (300 DPI or higher)
- ✅ Proper file type (Vector preferred, high-res PNG accepted)
- ✅ Sized correctly for your print area
- ✅ Clean background (transparent when needed)
- ✅ Colors set up for accurate reproduction
- ✅ Centered & aligned properly on the artboard
🔍 Why File Quality Matters
We get it—designing for print can feel overwhelming. But the file you send directly impacts how crisp your image looks, how aligned it appears on the shirt, and how quickly we can get it printed and out the door.
Poor file prep can lead to:
- Blurry prints due to pixelation
- Off-centered artwork
- Unexpected white boxes around designs
- Delayed production while we wait on a corrected file
And we’re not in the business of disappointing customers—so let’s talk about how to avoid that.
🧠 Our Best Practices for Print-Ready Files
Here’s a checklist to help you create a worry-free, high-quality design file.
1. Choose the Right File Format
We accept many file types, but some are way better than others.
Preferred | Accepted (if high-res) | Avoid |
AI (Adobe Illustrator) | PNG (transparent background) | JPG (unless large) |
EPS | PDF (vector exported) | Screenshots |
SVG | Word docs, low-res PNGs |
💡 Pro Tip: If your logo or design was created by a designer, ask for the vector version!
2. Stick to 300 DPI or Higher
DPI stands for dots per inch and tells us how sharp your image is.
Anything below 300 DPI risks looking pixelated, especially when enlarged.
To check DPI:
- Open your file in Photoshop or Illustrator and check the image size/resolution
- If you’re unsure, email us—we’ll review it for free
3. Keep Backgrounds Transparent (When Needed)
If you’re uploading a PNG, it should have a transparent background unless you want a white square behind your design. This is especially important for logos or text overlays.
Not sure if your file has a transparent background? Open it in an image viewer or ask our team to check.
4. Size It Right
Designs should be sized to match how big you want them to appear on the shirt. If you upload a tiny logo and want it across the chest, it’ll lose quality when we stretch it.
🔸 Full chest print area: ~11″–12″ wide
🔸 Pocket-sized logo: ~3″–4″ wide
🔸 Back designs: Can be larger, depending on placement

5. Align and Center the Artwork
Centering your design in the artboard makes our print setup faster and more accurate. Use guides or canvas tools to center both vertically and horizontally.
💡 We’ll always double-check placement, but a well-centered file saves time (and helps prevent mistakes).
🎁 Bonus Tip: Ask Us for Help (It’s Free!)
If you’re not 100% confident your file is print-ready, let us check it. Seriously.
Our design team will review your file at no extra charge and offer feedback or suggestions if something needs fixing.
We can even help convert JPGs or PDFs into print-ready formats for you.
🧵 Common File Issues We See (and How to Fix Them)
❌ Issue | ✅ How to Fix It |
Blurry when enlarged | Send vector or high-res file (300 DPI) |
White box around design | Export PNG with transparent background |
Off-center design | Align artwork to canvas center |
Colors print differently | Use Pantone or CMYK values if needed |
Wrong file type | Export from Canva/Photoshop as PNG or PDF |
🧭 Final Thoughts: Keep It Clean, Clear & Centered
Getting a high-quality custom tee isn’t complicated—you just need the right file.
To recap:
- Use vector or high-res files
- Keep backgrounds clean or transparent
- Size and center your design
