As a sublimation printing material supplier, we know that heat press calendar are important to a sublimation printing manufacture,it will directly effect your selling products like the clothes or home textile images. Today let we discuss what should we do under the heat and press of the calendaring unit.
Under the heat and pressure of the heat press or calendaring unit, the solid dye on the printed transfer paper is converted to a gas and penetrates into the fabric. The dye heat press on the fibers of the fabric which makes the colors quite durable, wash-resistant, and colorfast.
This process will yield best results on 100-percent polyester materials. Why not natural fibers like cottons? The same heat that sublimates the dye also slightly melts the polyester, which is basically a plastic. (Cotton and other natural fibers will not melt when exposed to the heat of a heat press, but will instead burn, which is a bad thing.) By “melting” I don’t mean that the fabric turns into a gooey mess, but it’s just enough to open up tiny gaps in the polyester fibers, and the gaseous dye then penetrates into these gaps. When the heat is removed, both the dye and the fibers resolidify, fused as one. This explains why dye-sub printing is so durable and colorfast.
By the way, if you use a heat press calender rather than a flatbed heat press, you may need to use a protection paper to protect the fabric and the rollers of the calender.
We supplier many kinds Sublimation Material like roller heat press machine, sublimation printer also the sublimation paper , any need, pls feel free to let me know, we will waiting for you!

Here’s the difference – we mentioned that the previous product is meant for white fabrics. Did you note that? Well, this particular product is meant for colored and dark fabrics. As for the features, the two transfer papers are virtually the same. Let’s go over them quickly.
