What's the best temperature for sublimation printing?

For most sublimation projects, you'll want to set your heat press to a nice, hot 400 degrees Fahrenheit. That's the sweet spot for getting those colors to transfer brightly.

How long do I press a sublimation print for?

You typically need to press it for about 45 to 60 seconds. Just make sure you're using firm, even pressure across the entire design.

Can I sublimate at 350 degrees instead?

It's not recommended. 350 degrees is too low and won't turn the solid ink into a gas, so your design will likely come out faded and won't permanently stick to the fabric.

Should I use RGB or CMYK for my sublimation designs?

Always design in CMYK. Your printer uses CMYK inks, so designing in that color mode gives you a much more accurate preview of your final printed colors.
