Sublimation printing has long been one of the digital printing methods used by many businesses and creative companies to create unique designs, professional looks and bright icons. Designing stylish t-shirts and personalized mug designs are typical uses for sublimation printing. Many people ask, can we do sublimation printing on plastic items? The answer is "yes", but he has certain conditions. This article will discuss with you about sublimation printing on plastics.
What is Dye Sublimation Transfer?
Dye sublimation transfer is a technique of mirroring pictures and images on sublimation transfer paper using an inkjet printer with sublimation inks. On the substrate, the color of the image on paper is vividly transferred to textiles, porcelain cups, porcelain plates, metals and other materials through a new process.
This is a high-temperature manufacturing process in which special sublimation inks are "sublimated" from the sublimation paper to the surface of the item being printed at temperatures up to 400°F.
What kind of plastic can be sublimated?
Just about anything with the right chemical composition—that is, made of polymers—can be printed. Or, if not, if your substrate, be it leather, wood, glass, or non-polymer plastic, will retain clear or white primer spray throughout the sublimation printing process
There is of course an important condition that any printed objects or their surface polymers should be able to withstand the high temperatures during the sublimation process. High temperatures can cause problems for some materials including glass, wood, leather and quite a few types of plastics.
The main problem with plastics is deformation at high temperatures, so if you want to print on a plastic item, it should be reinforced, for example, with fiberglass.
Therefore, by accepting the two conditions of printing and high temperature, we can conclude that if you want to sublime your plastic products, you need to cover your printed objects with white or transparent polymer coatings, so that these substrates can be Dye sublimation printing at high temperatures. Some plastics can already be printed, such as Mylar-covered acrylic sheets.
What do I need to pay attention to when sublimation transfer to plastic?
-
Plastic items should be flat.
Plastic products that are already formed, such as 3D printed items, will not work, even if reinforced with fiberglass.
-
Not all plastics can be sublimated.
Many plastics, even with reinforcement and coatings, cannot be sublimated. Because they simply cannot withstand high temperatures.
-
Avoid dark colors
It is well known that sublimation printing is suitable for sublimation printing in white and light colors, because it allows the color to be expressed better. If you use tan or light gray, then you may lose 15%-25% of the color gamut.
Conclusion
Sublimation in plastic is difficult, but it's worth experimenting and getting the best combination. More and more designers are trying to print their designs onto acrylic or other plastics using various combinations of printers, inks, temperature, and time.
