Thermal sublimation is a printing technique used for mugs, beakers and covers (iPad, Kindle, Smartphone).
When printing with thermal sublimation, the design or text are first printed back-to-front on a carrier foil. By applying a lot of heat (hence ‘thermal’) the design is then steamed off of the foil onto the product. A special layer on the product reacts with colour pigments and fixates them into the products permanently.
The result is a vividly coloured image that is integrated directly into the product's surface - the design does not protrude from the product. Extreme durability also after exposure to sunlight make thermal sublimination a long-lasting and high-quality option for accessories.
NB – The optimal resolution for prints with thermal sublimation is 400 dpi. If your graphics have a higher or lower resolution, this is bound to influence the quality of the print.
