Your design may look incredible on screen, but that doesn't mean it's print-ready. Here's everything you need to know to prepare your artwork for a flawless DTF transfer—no reprints, no surprises.
Rule #1: Resolution Is King (300 DPI Minimum)
The number one mistake we see at Sky Print House is low-resolution artwork. If your design looks pixelated when you zoom in at 100% on your screen, it will look pixelated on the shirt.
How to check in Photoshop: Go to Image > Image Size. Look at the "Resolution" field. If it says 72 DPI, you need to upscale or recreate your artwork.
Rule #2: Transparent Backgrounds Are Non-Negotiable
DTF printing doesn't have a white ink "cutout" feature like screen printing. If your file has a white background box, that white box will print on your garment.
-
Correct Format:
.PNGwith transparency enabled. - Check: Open your file. If you see a checkerboard pattern behind your design (in Photoshop, Canva, or Illustrator), you're good.
-
Avoid:
.JPGor.JPEGfiles. These formats do not support transparency.
| File Format | Transparency | Recommended? |
|---|---|---|
| PNG | ✅ Yes | Best Choice |
| PSD (Photoshop) | ✅ Yes | Accepted |
| PDF (Vector) | ✅ Yes | Accepted |
| JPG / JPEG | ❌ No | Avoid |
Rule #3: Get Your Sizing Right the First Time
We can't read your mind. If you upload a small logo and expect it to print across the entire chest, you'll be disappointed. Always design to the exact dimensions you want printed.
3.5" x 3.5"
12" x 14"
Pro Tip: When in doubt, include a note with your order specifying your desired print dimensions in inches.
Rule #4: Color Mode Matters (RGB vs. CMYK)
DTF printers use CMYK + White inks. If your design file is in RGB mode (the default for screens), some vibrant colors like neon green or electric blue may shift slightly when printed.
- Best Practice: Design in RGB for screen previews, but be aware that "out of gamut" colors may look different.
- Neon/Fluorescent Colors: These are impossible to replicate with CMYK inks. Expect a close approximation, not an exact match.
The Ultimate Artwork Checklist ✅
Before you upload, run through this list:
- ☐ Resolution is 300 DPI at final print size.
- ☐ File format is PNG with a transparent background.
- ☐ Dimensions are correct (e.g., 12" x 14" for full front).
- ☐ No stray pixels or unwanted white edges around the design.
- ☐ Text is rasterized or outlined (to avoid font issues).
