It looks like the image you uploaded has been enlarged significantly. To ensure the best print quality, please upload an image that has not been resized beyond 1.5 times its original dimensions.

Notes for our designers (optional)
We auto-trim unnecessary space from your artwork
When converting from RGB to CMYK for printing, especially in DTF (Direct to Film) printing, slight shifts in color can occur. This is because the RGB color gamut (the range of colors) is broader than CMYK, meaning certain vibrant RGB colors may not have an exact match in CMYK, leading to a duller or different color appearance in print. Colors may vary slightly when converting from RGB (screen) to CMYK (print)
We've removed the background and optimized your design size to help reduce any potential issues. If you notice anything that needs adjustment, feel free to leave a comment at checkout.
Please ensure your design is high-quality. We are not responsible for blurry, pixelated, or low-resolution images. Verify carefully before submitting.What you Upload and see here is EXACTLY what we'll print.

Print vs Embroidery — what’s the difference?
Print (DTF)
✔ Unlimited colors
✔ Great for photos & detailed designs
✔ Bold, vibrant graphics
Embroidery
✔ Raised stitched look
✔ Best for simple logos/text
✔ More professional & upscale feel
Quick tip:
Colorful or detailed = Print
Clean logo or branding = Embroidery
What is Expert Sizing?
We automatically size your design based on the garment and placement so it looks balanced and professional. Perfect if you’re unsure what size to choose.
Why do printed colors look different than my screen?
Screens use RGB. Printing uses CMYK. Some colors may appear slightly different in real life — this is normal in professional printing.
What files work best?
PNG (transparent), AI, PDF, or high-res JPG.
Cleaner files = better results.
Can I embroider detailed artwork?
Embroidery works best with simple designs. Small text or complex graphics may need to be simplified — otherwise we’ll recommend Print.
Shoulder Measured straight across from one shoulder seam to the opposite shoulder seam.
Chest Measured straight across from one underarm seam to the other (pit-to-pit).
Body Length Measured vertically from the top center to the bottom edge on the back side, as the back is slightly longer.
Sleeve Length Measured from the top edge of the sleeve straight down to the bottom edge.
