The Big Three:
300 dpi is the best resolution for fabric. Higher is wasted file space (no biggie), but lower means a drop in quality when printed. (An image pulled off of the Internet is only 72dpi for instance, and therefore will print poorly.)
RGB mode. It is true that CMYK is typically used for printing but this system starts with RGB which has brighter, better colors.
100% size (meaning please submit the graphic in the size you would like it printed.)
Acceptable File Formats:
- PNG, PSD, AI, EPS, PDF
