Getting premium print quality starts long before the printer runs. The single biggest factor is how your design file is prepared. Even a small mistake—wrong DPI, incorrect size, or transparency issues—can turn a great design into an average-looking print.
At Merch Factory, the system is built to be creator-friendly, but correct design preparation is still non-negotiable if you want sharp, vibrant, professional results.
This guide walks you through the exact process to submit designs that print cleanly every single time—whether you’re using DTF (Direct-to-Film) or DTG (Direct-to-Garment).
Here’s a complete guide to help you get it right every time.
1. Set the Correct Design Size (and DPI) from the Start
Always design at the actual print size you want on the garment.
Example:
If your design should print at 10 inches wide × 12 inches high, your canvas must be exactly 10” × 12”.
DPI Rules (Very Important)
- 300 DPI → industry standard (best quality)
- Supported range on Merch Factory: 250–600 DPI
What happens if you get this wrong?
- Below 250 DPI → blurry, pixelated prints
- Excessively high DPI → unnecessary file weight, editor issues
If Your Tool Shows Pixels (Not Inches)
Convert manually using this formula:
Inches × 300 = Pixels
Example:
- Width: 10 × 300 = 3000 px
- Height: 12 × 300 = 3600 px
Designing at the correct size eliminates stretching, softness, and scaling errors later.

2. Export Only as PNG (With Transparent Background)
Once your design is ready, export it as a PNG with transparency.
Why PNG?
- No compression loss
- Clean edges
- Supports transparency
- Best for apparel printing
Transparency ensures your design prints cleanly on any fabric color without unwanted backgrounds.
Color Mode Clarification
PNG files use RGB (screen colors). That’s perfectly fine.
Merch Factory’s print pipeline automatically converts RGB → CMYK during printing, ensuring ~99% color accuracy compared to what you see on screen.
⚠️ Avoid JPG/JPEG
- No transparency
- Color depth loss
- Edges may print dirty or boxed
3. Avoid Semi-Transparency, Shadows, and Blur Effects
This is the #1 hidden mistake creators make.
DTF and DTG printing work like this:
- Color ink is printed
- White ink is laid underneath to make colors pop
If your design contains:
- Opacity below 100%
- Soft shadows
- Feathered edges
- Blur or glow effects
…the white ink layer can partially show through.
Result?
- Washed-out colors
- Patchy or uneven prints
- Loss of sharpness
Best Practices
- Use solid colors
- Keep edges hard and clean
- Avoid drop shadows and glow effects
- Test your design on a dark background before exporting
If it looks odd on dark backgrounds digitally, it will look worse on fabric.
4. Create Designs Inside “Saved Products” (Recommended Workflow)
For the best accuracy and least errors, always create designs inside Saved Products on your Merch Factory dashboard.
Why This Matters
When you design via Saved Products:
- Your file goes through extra validation checks
- DPI, size, and transparency are auto-verified
- You get accurate front/back placement previews
- Scaling errors are eliminated
⚠️ Creating designs directly from New Order skips some of these checks and can lead to:
- Reprints
- Delays
- Incorrect sizing
✅ Pro Tip:
Always preview your design inside Saved Products before ordering.
What you see there is exactly what gets printed.
5. One-Minute Print-Ready Checklist ✅
Before submitting, confirm all of this:
- Canvas matches final print size (in inches or pixels)
- Resolution set to 300 DPI
- File exported as PNG with transparency
- No semi-transparency, blur, or shadow effects
- Colors look correct in RGB
- Design created & previewed in Saved Products
If all boxes are checked, your print quality will be sharp, vibrant, and professional.
