In 1957, Noël de Plasse, a researcher doing work for French textile company Lainie`re de Roubaix, made an interesting discovery. He found out that, under high temperature, certain solid dyes could pass right to the gaseous phase without first becoming a liquid. This physical process is referred to as sublimation, and what de Plasse had discovered was eventually termed Sublimation ink. Nothing much really was carried out with dye-sublimation till the late 60s, whenever it began to be used during early computer printers. Today, dye-sublimation printing has changed into a popular and versatile process that is predominantly used for various textile printing, but also rivals UV for printing on three-dimensional objects like mugs, smartphone covers, and also other specialty items.
A dye-sublimation ink is made up of solid pigment or dye suspended in the liquid vehicle. A photo is printed onto a transfer paper-also referred to as release paper-as well as the paper is brought into contact with a polyester fabric employing a heat press. Under heat and pressure, the solid dye sublimates and suffuses to the fabric, solidifying on the fibers. The image physically becomes section of the substrate.
For many years, printing by way of a transfer medium continues to be the conventional dye-sub method. However, there have emerged systems-called direct Sublimation paper or direct disperse-that can print directly onto a fabric without requiring a transfer sheet. It’s tempting to consider, “Aha! Now I can save cash on transfer paper,” but it’s not quite as basic as that. Both kinds of dye-sub have their own advantages along with their disadvantages, and when you’re a new comer to the technology, or wish to purchase a dye-sub system, it pays to learn the advantages and limitations of every.
The important advantage of by using a transfer process is image quality. “You end up with a more in depth image, the sides can be a little sharper, text is much more crisp and sharp, and colours are definitely more vivid,” said Tim Check, Product Manager, Professional Imaging for Epson. Epson’s SureColor F Series dye-sublimation printers comprise the F6200, F7200, and F9200.
With transfer paper, during heat transfer vinyl, the ink doesn’t penetrate far to the substrate, remaining near to the surface. In contrast, direct disperse penetrates further into dexopky66 fabric, which-just like inkjet printing on plain paper-ensures that fine detail is lost and colors become less vivid.
“For me, the difference will definitely be clarity because you’re always getting a cleaner, crisper print when you’re performing a print to paper and after that transferring,” said Steven Moreno, founder and principal of L.A.’s MY Prints, a digital print shop which specializes in apparel prototyping and garments for entertainment industry costume houses, and also flags, banners, along with other display graphics. Most of MY Prints’ work is dye-sub-based. “For something with fine detail we may always want to use transfer paper.”
An additional advantage of using a transfer process is that you can assist any kind of surface having a polyester coating: banners, mugs, flip-flops, you name it. “There are numerous applications, and that’s really the benefit of a transfer process,” said Check. “It causes it to be a very versatile solution.”
