Digital printing is replacing traditional methods in various branches of the graphics industry. There are actually multiple causes of this shift nevertheless the main drivers are the cost-efficiency, possibility to personalise prints and the flexibility of such machines.
This can be 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 which need multiple colours and photographic imagery. Digital alternatives are best for the personalisation of prints, which is very well liked nowadays.
What exactly is dye sublimation printing?
Sublimation printing is a technique which uses heat sensitive inks. These inks develop into gas intoxicated by heat and combine using a 100% polyester medium. Considering that the ink becomes area of the structure from the material, the pictures in the fabric don’t fade or crack – even with multiple washings.
What do you want for doing it?
You want various items to create sublimated textiles including flags, displays, sportswear, fashion, interior decoration and much more.
1. Printer and ink
A high-quality printer built with Sublimation paper is crucial. The Roland Texart RT-640 and XT-640 are printer which can be created specifically 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 many colour-giving elements and so are highly concentrated, which can be necessary to create beautiful, vivid and crisp images.

To create high-quality sublimation prints, you want a transfer paper which has high ink absorption and dries quickly. The paper has to stay flat and might not wave after printing. It is also critical that the paper releases the ink when heating. The Roland Sublimation Paper does everything that and it is therefore the perfect paper for your sublimation prints.

Printing is simply the first step in the dye sublimation process. For sublimation to occur, you will need heat and pressure. Heat presses may be found in a variation of sizes and shapes, but you will need a calender for roll-to-roll sublimation. Roland DG gives the Texart CS-64, an experienced calender system that may be fast, affordable and simple to operate, so that it is a great finishing partner to the Texart sublimation printers.

You will need a minimum temperature of 180°C for sublimation to occur. According to the textile, we advise a temperature of 185 to 200°C and an exposure time period of about 55 seconds to simultaneously heat the ink around the transfer paper along with the polymer fibres in the substrate, enabling the transfer of ink to media. Please dexopky66 that you will need to alter the temperature and/or exposure time as soon as the effects are not satisfying.
When selecting a textile for sublimation printing, it is essential that you have a 100% polyester fabric which is pre-shrunk. This avoids shrinking when heat is applied. Roland DG offers a textile that is perfect for heat transfer vinyl.
