How to Avoid Common Artwork Mistakes When Ordering DTF Transfers
Reading Time: 7–8 minutes
Introduction
Most DTF transfer problems don’t start at the printer. They start with the artwork file.
After printing thousands of transfers, we’ve seen the same mistakes come up again and again — blurry designs, white boxes around logos, colors that don’t match, text that’s too small to read. Almost all of these problems are completely avoidable with a few simple checks before you upload your file.
This guide covers the most common artwork mistakes people make when ordering DTF transfers, why each one causes problems, and exactly how to fix them. For a complete overview of what makes a file print-ready, start with Artwork Requirements for DTF Transfers.
Mistake 1: Using a Low-Resolution File
This is the most common artwork mistake we see, and it’s responsible for more blurry, pixelated transfers than anything else.
What goes wrong: Files designed at 72 DPI (screen resolution) look sharp on a monitor but print blurry at full size. The same happens when a small file is scaled up to a larger print size.
How to fix it: Always design your artwork at 300 DPI at the actual print size. If you want a 10” × 10” chest print, your canvas should be 10” × 10” at 300 DPI. Don’t design small and scale up.
Quick check: In Photoshop, go to Image → Image Size and confirm the resolution is 300 Pixels/Inch at your intended print dimensions.
Mistake 2: Sending a File With a White Background
This one surprises a lot of first-time customers. They send a logo on a white background, expecting the white to disappear — but it doesn’t. The printer prints everything in the file, including the white background.
What goes wrong: You end up with a transfer that has a solid white rectangle around your design. On a dark shirt, this looks like a big white box.
How to fix it: Remove the background from your design and save the file as a PNG with a transparent background. In Photoshop, look for the gray-and-white checkerboard pattern behind your design — that’s how you know the background is truly transparent.
Quick check: Open your PNG file in a web browser. If the background looks white, it’s not transparent. If it shows a gray or checkered pattern, you’re good.
Mistake 3: Using the Wrong File Format
Not all file formats work for DTF printing. Using the wrong one can cause background problems, color issues, or quality loss.
What goes wrong: JPG is the most common culprit. JPG files don’t support transparency, so they always have a white background. They also use lossy compression, which means image quality degrades every time you save the file.
How to fix it: Use one of these formats instead. See our full guide: Best File Types for DTF Transfers: PNG, AI, PSD, SVG & PDF Explained.
- PNG — Best for most designs. Supports transparency and keeps quality high.
- AI or SVG — Best for vector artwork. Scales to any size without quality loss.
- PSD — Good for layered Photoshop designs with transparent backgrounds.
- PDF — Works well for print-ready vector files from a designer.
Formats to avoid: JPG, GIF, BMP, and WebP.
Mistake 4: Using CMYK Color Mode Instead of RGB
What goes wrong: Traditional printing uses CMYK color. DTF printing uses RGB. If you send a CMYK file, the colors get converted during processing — and that conversion isn’t always accurate. Reds can shift orange. Blues can go dull. Vibrant colors can look flat.
How to fix it: Before exporting your file, make sure the color mode is set to RGB.
- In Photoshop: Image → Mode → RGB Color
- In Illustrator: File → Document Color Mode → RGB
Mistake 5: Designing at the Wrong Size
What goes wrong: Some customers design at a standard canvas size without thinking about where the design will actually sit on the garment. Others design a logo at 2” × 2” and expect it to print at 12” × 12” — which requires scaling up and losing resolution.
How to fix it: Before you start designing, decide on the final print size and set your canvas to those exact dimensions at 300 DPI. Common DTF print sizes:
- Left chest logo: 3–4” wide
- Full front/back design: 10–12” wide
- Sleeve print: 3–4” wide
Mistake 6: Text That’s Too Small to Print Clearly
What goes wrong: Very small text — especially thin or hairline fonts — can bleed together, lose definition, or become unreadable when pressed onto a garment.
How to fix it:
- Keep body text at 8pt or larger at the actual print size
- Avoid very thin or hairline fonts for small text
- Bold or heavier font weights hold up better at small sizes
- Script and decorative fonts need to be larger than standard fonts to remain readable
Mistake 7: Not Outlining Fonts in Vector Files
What goes wrong: When you send a vector file with live text, the printer’s software needs to find the same font on its system. If the font isn’t installed, it substitutes a different one — which can completely change the look of your design.
How to fix it: Before saving your AI or SVG file, select all text and convert it to outlines.
- In Illustrator: Select all text → Type → Create Outlines
- In other vector programs: Look for “Convert to Curves” or “Outline Text”
Mistake 8: Flattening the File Before Exporting
What goes wrong: When you flatten a Photoshop file, all layers merge onto a white background. If you then export this flattened file as a PNG, the white background gets baked in — even though PNG supports transparency.
How to fix it: Never flatten your file before exporting for DTF. Instead, export directly from the layered file using File → Export → Export As, choose PNG, and make sure the Transparency option is checked. For a full walkthrough, see: How to Make Artwork Transparent for DTF Printing.
Mistake 9: Uploading a Screenshot or Web Image
What goes wrong: Screenshots and web images are almost always 72–96 DPI — far below the 300 DPI needed for DTF printing. They also often have white or colored backgrounds baked in.
How to fix it: Always use the original source file for your design. If you don’t have it, contact the designer or brand to request a high-resolution print-ready file.
Mistake 10: Not Checking the File Before Uploading
The final and most avoidable mistake is simply not reviewing the file before you submit your order. Before every order, run through this quick checklist:
- ✅ Resolution is 300 DPI at the actual print size
- ✅ Background is transparent (checkerboard visible in design software)
- ✅ File is saved as PNG, AI, PSD, SVG, or PDF
- ✅ Color mode is set to RGB
- ✅ Canvas size matches the final print dimensions
- ✅ Text is legible at the actual print size
- ✅ Fonts are outlined in vector files
- ✅ No unwanted white edges or halos around the design
Conclusion
Most DTF printing problems are artwork problems — and most artwork problems are preventable. Here’s a quick summary of the ten mistakes to avoid:
- Low-resolution file (below 300 DPI at print size)
- White background instead of transparent
- Wrong file format (especially JPG)
- CMYK color mode instead of RGB
- Wrong canvas size
- Text that’s too small to print clearly
- Fonts not outlined in vector files
- Flattened file with a white background
- Screenshot or low-quality web image
- Not checking the file before uploading
Fix these before you order, and you’ll get better transfers, fewer reprints, and a smoother experience every time.

Frequently Asked Questions
What is the most common DTF artwork mistake?
Low resolution is the most common issue. Files designed at 72 DPI look sharp on a monitor but print blurry at full size. Always design at 300 DPI at the actual print size.
Why does my transfer have a white box around it?
Your file had a white background instead of a transparent one. Remove the background in your design software, save as PNG with transparency, and reorder. See: How to Make Artwork Transparent for DTF Printing.
Can DTFera fix my artwork before printing?
We print files exactly as submitted and don’t redesign customer artwork. If you’re unsure whether your file is ready, reach out before placing your order and we’ll let you know what needs to be adjusted.
What file format should I use for DTF transfers?
PNG is the best choice for most designs. For vector artwork, AI or SVG are excellent options. Avoid JPG — it doesn’t support transparency. Full guide: Best File Types for DTF Transfers.
How do I know if my colors will print correctly?
Make sure your file is in RGB color mode before uploading. CMYK files can cause color shifts during conversion.
What should I do if I’m not sure my file is ready?
Run through the pre-order checklist in this article. If you’re still unsure, contact DTFera before placing your order.
