Digital printing is replacing conventional methods in several branches from the graphics industry. You will find multiple reasons for this shift but the main drivers are definitely the cost-efficiency, possibility to personalise prints and the flexibility of such machines.
This really is 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. Digital alternatives are best for the personalisation of prints, which is very popular nowadays.
Precisely what is dye sublimation printing?
Sublimation printing is a technique which utilizes heat sensitive inks. These inks become gas under the influence of heat and combine having a 100% polyester medium. Because the ink becomes part of the structure from the material, the photos in the fabric don’t fade or crack – even after multiple washings.
What do you require because of it?
You will need various things to create sublimated textiles including flags, displays, sportswear, fashion, interior decoration plus much more.
1. Printer and ink
A high-quality printer equipped with Sublimation paper is vital. The Roland Texart RT-640 and XT-640 are printer which are specifically made for sublimation printing. The printers can be purchased with Texart ink in four (CMYK) or eight colours (CMYK, Lc, Lm, Or and Vi). These inks have lots of colour-giving elements and are highly concentrated, which can be required to create beautiful, vivid and crisp images.

You want a minimum temperature of 180°C for sublimation to occur. Based on the textile, we advise a temperature of 185 to 200°C plus an exposure time period of about 55 seconds to simultaneously heat the ink in the transfer paper and the polymer fibres throughout the substrate, enabling the transfer of ink to media. Please dexopky66 that you will want to regulate the temperature and exposure time once the effects are not satisfying.
When selecting a textile for sublimation printing, it is essential that you take a 100% polyester fabric that is pre-shrunk. This avoids shrinking when heat is applied. Roland DG offers a textile that is good for heat transfer vinyl.
