Quick tip:

Colorful or detailed = Print

Clean logo or branding = Embroidery

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.

Screens use RGB. Printing uses CMYK. Some colors may appear slightly different in real life — this is normal in professional printing.

PNG (transparent), AI, PDF, or high-res JPG.

Cleaner files = better results.

Embroidery works best with simple designs. Small text or complex graphics may need to be simplified — otherwise we’ll recommend Print.
