Query: To T-shirts, is it compulsory to use polyester T-shirts/fabric with dye sublimation printing?
Answer: There’s been a great deal of experimentation with different organic fibers and blended all-natural fibers (such as the 50/50 cotton tee), and also for the most part, it’s best, when using authentic dye sublimation printing on sublimation supplies, to utilize polyester materials.
Some have reported success using the 50/50 cotton blouse, but many prefer to use accessible digital printers which have the appropriate inks for listening to cotton, silk, or screen-print inks that are also invented for cotton or 50/50 t-shirts.
It’s very important to realize how dye sublimation printing functions to have the ability to justify the above mentioned statements, however.
The sublimation printing process contains a dye ink that’s often notated as a CMYO ink (cyan-magenta-yellow-overprint) compared to conventional inkjet printing ink that’s the conventional CMYK (cyan-magenta-yellow-black). The dye is published into a newspaper, popularly called sublimation transfer paper or dye sublimation transfer paper then transferred through pressure and heat to materials, coasters, mouse pads, polyester materials which are used in clothes and advertising screens and banners, and a number of other products.
Due to the chemistry involved in those dyes, together with pressure and heat changing the dye into a gasoline, it becomes a part of the substrate that it’s fused to. The warmth not only transforms the dye into a gas, in addition, it extends the pores of polyester or polymers (like the polymeric coatings on various substrates or substances) and enables the gas to be drawn to the pores. When the substrate melts, the pores close and let the dye to develop into strong, permanently embedded in the cloth or polymeric substance. This dye additionally is fade resistant and likely to endure for many, many decades.
Since the pores of the substrate have to maintain the dye if the pores close, other sublimation supplies or substrates won’t hold the dye. Thus, if you should publish 100% cotton t-shirt with the dye sublimation printing process, the cotton wouldn’t have the chemistry required for the pores to shut gently round the dye to have the ability to continue to the substance or substrate. Even things like coffee mugs have to get pre-treated using a polymeric coating or so the dye sub print won’t operate. Be aware that sublimation also does not work on dark substrates, and that a marginally off-white substance will always work best.
