When printed onto Sublimation paper, Sublimation ink allows for very high quality printing using a heat press, substrates that are polymer based or coated or polyester material. Given the correct amount of heat, pressure and time you will be left with beautifully printed items, that don’t fade or wash out.
When pressing a mug which has been polymer coated, you can run your finger over the image and you wont be able to feel it. This is because the ink has turned to gas when heated, the pores of the polymer coating have open and the gas fills the pores; when cooled the pores close trapping the image behind it, hence it becomes part of the coating.
You need to use Sublimation inks for heat transfer printing, normal dye inks will not work.
When printing to items that are not polymer coated or polyester based the results will be far lower than that of ones that are.
The process is simple and consists 5 stages:
- Print transfer (using sublimation ink and paper)
- Cut transfer
- Heat tape tanfser to substrate (mug etc)
- place in heat press for desired time (mugs 180c for approx 3-3.5 mins)
- remove item and transfer
What you should be left with is a beautiful item with crisp images and bright colours.
