Digital printing is replacing conventional methods in several branches from the graphics industry. There are actually multiple causes of 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 in the textile printing business. Traditional screen-printing is replaced by digital textile printing solutions like Sublimation ink for shorter production runs and prints which need multiple colours and photographic imagery. Digital alternatives are best for the personalisation of prints, which can be very well liked nowadays.
What is dye sublimation printing?
Sublimation printing is actually a technique that utilizes heat sensitive inks. These inks turn into gas under the influence of heat and combine by using a 100% polyester medium.
