How Does the Sublimation Process Work?
Just like any printing process, sublimation starts with the design stage. Coming up with a good design is crucial since the chosen image on the computer is the one that will reflect on the final print.
The design is then printed on a heat transfer paper, also known as sublimation paper. This paper is explicitly used for the transfer of the image when exposed to heat. A sublimation paper uses CMYO colors. Hence, the Sublimation Printer used must also accommodate the same. Luckily, most of the modern printers can alternate between the CYMK and CMYO colors.
After printing the image, the next process entails the heat transfer of the artwork to the final material. In this case, the material used must support sublimation printing. Polyester and polyester-coated materials are typically used in the process because they produce permanent prints. Other materials such as cotton are also an option, although the print won’t be permanent.
The heat transfer process requires a heat source. Depending on the material, there are different heat source options used. These include a heat transfer machine, flat bend machine, cups sublimation machines among others. A specific amount of heat must be used to produce a quality image, and the image must be allowed to cool off to guarantee durability.
It is evident that the “next big thing” in the personalization world is UV printing, but what makes it so great? What can you do with a UV Printer that you can’t do with sublimation or some other color printing method? And finally, is the equipment worth the price?
Before answering this, I should clarify for the benefit of newbie readers what this is. A UV inkjet printer is a lot like the inkjet printers we use to print documents in the office. The main difference is they are designed to print on other substrates besides paper, plus they use a UV light source to cure the inks after they are deposited onto the item/substrate.
I’ve been using a UV printer for a couple of years now and I think I have discovered a fair share of the good and bad points of the process.
First, the bad points: Two come immediately to mind. One is that these printers don’t print on everything. Although some salespeople may make it sound that way, the truth is, there are countless products just begging for UV images but the inks won’t adhere properly. It does print on most things, especially if you use an adhesion promoter. This is usually a liquid that can be applied with a paper towel prior to printing. A couple of UV Roll To Roll Printers on the market actually allow you to install the promotor like an ink allowing you to “print” the liquid prior to printing the ink.
