Question 1

What are the substrates for sublimation?

Accepted Answer

Sublimation works on materials containing polyester or a polymer coating. Common substrates include polyester fabrics, polymer-coated ceramics, metals, and certain plastics.

Question 2

What blanks to use for sublimation?

Accepted Answer

Use blanks specifically designed for sublimation, such as polyester apparel, polymer-coated mugs, aluminum sheets, and specially treated plastic items. These blanks are engineered to bond with sublimation inks effectively.

Question 3

Can I sublimate on 50% polyester and 50% cotton?

Accepted Answer

Yes, but the results may be less vibrant and less durable compared to higher polyester content fabrics. Sublimation dyes bond primarily with polyester fibers, so a 50/50 blend may produce a faded or vintage look.

Question 4

What are the requirements for sublimation blanks?

Accepted Answer

Sublimation blanks must have a high polyester content or a polymer coating to bond with sublimation inks. They should also withstand high heat during the transfer process without deforming or degrading.

Question 5

What are the three common materials used as printing substrates?

Accepted Answer

The three common materials are polyester fabrics, polymer-coated ceramics (like mugs and tiles), and specially coated metals (such as aluminum sheets).

Question 6

Can you do sublimation on plastic cups?

Accepted Answer

Yes, but the plastic must be able to withstand the heat of the sublimation process and should have a polymer coating designed for sublimation. Not all plastics are suitable, so it's important to use blanks specifically intended for sublimation printing.
