WHAT CAN BE SUBLIMATION PRINTED? 

You can sublimation print onto a wide variety of items provided that the surface is suitable for sublimation printing. We offer both 'hard' and 'soft' items that are suitable for sublimation printing - full details of our extensive range can be found on our sublimation imprintables pages.
Hard items include specially coated plaques, signs, placemats, coasters, tiles, mugs, metal and keyrings. Soft items include polyester fabric, canvas, t-shirts, cushions, car sun screens, pillowcases and more! A sublimation print on a suitable polyester fabric is permanent, feels like part of the fabric with no 'hand' and will not crack, peel or fade.

WHAT CANNOT BE SUBLIMATION PRINTED?

Cotton fabric and garments - because dye sublimation printing is always done on polyester, polymer, or polymer coated items for the reasons mentioned above. It is possible to sublimation print a cotton fabric but the image will wash out within a few washes, it will not be a permanent image in the way that it is on a 'man made' fabric. 
Also unsuitable are other items that have a polyester/polymer coating but are unable to withstand the temperatures required for dye sublimation printing.
