File Requirements
Follow these specs for clean prints and same-day processing.
Must be built at final physical size.
Save with a transparent background (recommended).
Upload at the exact dimensions you need printed.
Accepted Formats
- PNG (Highly Recommended): The standard for DTF printing. It preserves high quality and supports transparent backgrounds.
- Vector Files (AI, EPS, SVG, PDF): We accept these if submitted properly. All text/fonts must be outlined and all strokes expanded.
- Avoid JPGs: JPG files do not support transparency. If you upload a JPG, the solid background (usually a white or black box) will print onto your shirt.
Resolution
Your artwork must be submitted at 300 DPI at the final output size.
Do not take a tiny, low-resolution thumbnail and "scale it up" to 300 DPI in Photoshop. Upscaling does not create missing data; it only stretches existing pixels, resulting in blurry, jagged, and heavily pixelated prints. Design your artwork at the correct size from the start.
Sizing Rules
Upload your files at the exact physical dimensions you want them printed on the garment. Crop away any empty transparent space around your design so the measurements are accurate.
Common Print Sizes
- Left Chest: ~3.5 in wide
- Full Front: ~10–12 in wide
- Full Back: ~11–12 in wide
- Sleeve: ~3 in wide
Background & Transparency
DTF requires a white underbase behind every colored pixel. Because of this, transparency is critical.
- Backgrounds Print: If your art has a white background block or box, our printers will print a giant white square.
- Remove All Backgrounds: Save your PNG files with a transparent background before uploading.
- Avoid Halos: Soft, fuzzy, or semi-transparent shadow edges can confuse the RIP software, resulting in a solid white "halo" behind the fade. Use crisp, hard edges.
Color Mode
Keeping it simple: RGB files are perfectly fine to upload.
Remember that monitors are backlit and display colors differently than physical CMYK printer inks. Neon and extremely bright screen colors will naturally shift slightly when translated to physical ink. If you have a critical color match (like a specific brand logo), we strongly encourage ordering a small test print first.
Line/Detail Limits
- Avoid Hairline Strokes: Lines thinner than 0.5mm may print, but they do not have enough surface area for the adhesive powder to bond strongly to the shirt.
- No Micro Text: Extremely tiny text will not survive the wash cycle.
- Keep Details Bold: Thicker, bolder details ensure maximum durability and a longer lifespan for the garment.
Naming & Upload Tips
- File Naming Conventions: Name your files clearly (e.g., "Front_Logo_10inch.png") to help you organize your gang sheets and reorders.
- Gang Sheets: You can upload one file per design, or combine multiple designs onto a single large gang sheet to save money. If ganging, leave ~0.5 inches between designs for easy cutting.
- Spelling Check: We do not proofread. Double-check your spelling before uploading!
Rejections & Fixes
If we spot a catastrophic error in your file, we will pause your order to prevent a bad print. Here are the most common reasons and how to fix them:
-
Low-Resolution: The image is heavily pixelated.
Fix: Redraw the art or export from the original source file at 300 DPI at the final print size. -
Background Box: The design has a solid white or black background.
Fix: Use Photoshop, Canva, or a background remover tool to delete the background, and export as a transparent PNG. -
Mirrored Art: The customer flipped the text backward.
Fix: Flip it back to normal readable text. Our RIP software handles the mirror step. -
Wrong Size: A 2-inch logo was submitted for a 12-inch back piece.
Fix: Adjust your canvas size in your design software to 12 inches wide and re-export. -
Tiny Details: The artwork relies on microscopic dots or hairline scribbles.
Fix: Add a stroke to your paths or use a bolder font to ensure the powder adheres properly.
Frequently Asked Questions
Do I need to mirror my artwork?
No! Please upload your files in normal, readable orientation. Our printers automatically mirror the art during the printing process.
What file format is best?
High-resolution PNG files with a transparent background are the most reliable and recommended format for DTF printing.
What does '300 DPI at size' mean?
It means if you want your design to be 10 inches wide on the shirt, your digital canvas must be exactly 10 inches wide, and set to 300 Dots Per Inch.
Can you upscale or fix my file?
To keep our same-day shipping promise, we do not offer graphic design, background removal, or upscaling services. You must submit a print-ready file.
My PNG has a white box behind it — will it print?
Yes, the printer reads any white pixels as white ink. If there is a white background box in your file, a white square will be pressed onto your garment.
How do I remove the background?
You can use tools like Photoshop (Magic Wand or Select Subject), Illustrator, or web apps like Canva Pro or remove.bg to delete the background before saving as a PNG.
Can I upload multiple designs?
Yes! You can either upload multiple single designs individually, or build a "gang sheet" by placing multiple designs onto one large canvas to save on costs.
Why did my small text not hold?
Ultra-thin lines and micro-text do not possess enough surface area for the DTF adhesive powder to grab onto. During the wash cycle, these fragile pieces can flake off. Always use bold lines.
Do gradients/photos work?
Yes, high-resolution photographs and smooth gradients print exceptionally well with DTF technology. Just ensure the fade does not end in semi-transparent pixels to avoid haloing.
