Digital printing is replacing conventional methods in different branches of the graphics industry. You can find multiple reasons for this shift nevertheless the main drivers would be the cost-efficiency, possibility to personalise prints and the flexibility of the machines.
This is no different within the textile printing business. Traditional screen-printing is replaced by digital textile printing solutions like Sublimation ink for shorter production runs and prints that need multiple colours and photographic imagery. The digital alternatives are ideal for the personalisation of prints, which can be very popular nowadays.
What is dye sublimation printing?
Sublimation printing is really a technique that uses heat sensitive inks. These inks develop into gas intoxicated by heat and combine by using a 100% polyester medium. Ever since the ink becomes section of the structure from the material, the pictures around the fabric don’t fade or crack – even after multiple washings.
What do you want because of it?
You want various items to create sublimated textiles including flags, displays, sportswear, fashion, interior decoration and even more.
1. Printer and ink
A high-quality printer equipped with Sublimation paper is essential. The Roland Texart RT-640 and XT-640 are printer that happen to be specifically made for sublimation printing. The printers are available with Texart ink in four (CMYK) or eight colours (CMYK, Lc, Lm, Or and Vi). These inks have lots of colour-giving elements and so are highly concentrated, that is necessary to create beautiful, vivid and crisp images.

You want a minimum temperature of 180°C for sublimation to happen. Based on the textile, we advise a temperature of 185 to 200°C as well as an exposure time of about 55 seconds to simultaneously heat the ink on the transfer paper as well as the polymer fibres in the substrate, enabling the transfer of ink to media. Please dexopky66 that you will want to regulate the temperature and exposure time when the results are not satisfying.
When selecting a textile for sublimation printing, it is important that you practice a 100% polyester fabric that may be pre-shrunk. This avoids shrinking when heat is applied. Roland DG provides a textile that is great for heat transfer vinyl.
