Digital printing is replacing traditional methods in several branches in the graphics industry. You will find multiple factors behind this shift nevertheless the main drivers will be the cost-efficiency, possibility to personalise prints along with the flexibility of those machines.
This is certainly no different from the textile printing business. Traditional screen-printing is replaced by digital textile printing solutions like Sublimation ink for shorter production runs and prints which require multiple colours and photographic imagery. A digital alternatives are ideal for the personalisation of prints, that is increasingly popular nowadays.
Exactly what is dye sublimation printing?
Sublimation printing is really a technique which uses heat sensitive inks. These inks become gas intoxicated by heat and combine using a 100% polyester medium. Because the ink becomes section of the structure in the material, the images around the fabric don’t fade or crack – even after multiple washings.
What do you need for this?
You want various items to create sublimated textiles including flags, displays, sportswear, fashion, interior decoration plus much more.
