How does sublimation printing work in practice?

Sublimation printing is often also referred to as transfer printing. In a first production step, the desired print motifs are first printed on a transfer foil or transfer paper, which then transfers the individual colour pigments into the textile.

In detail, the individual production steps proceed as follows:
 
  1. Print motifs are printed mirror-inverted onto a transfer foil or transfer paper using special printing inks.
  2. Transfer ribbon is placed on the textile in the desired position with the printed side facing down.
  3. Heating of transfer ribbon and textile to approx. 230°C with the thermal transfer press.
  4. High-pressure application on transfer ribbon and textile.
  5. Dyes sublimate and penetrate the textile fibres as gases.
  6. Dyes combine with the textile fibres on a molecular basis.

Advantages of sublimation printing

1. Precise print result

No other textile printing process can reproduce motifs in such high quality as sublimation or transfer printing. Even very detailed motifs or complex photographs can be transferred to the textile with sublimation printing without any problems and true to the original.

The result is not only clear and distinct, but also particularly colour-intensive – in the long term. The sublimated colours hardly fade even with frequent washing.

2.Flexibility in design

Sublimation printing is a digital textile printing process. This means that there are virtually no limits to the design. While other printing techniques are often limited in their colour palette, with textile printing transfer printing all imaginable colours are available. There is also no need to compromise on design. Whether complex patterns, photography, artwork or graphics – the quality of the print result is always consistently high.

Print providers with a 3D configurator are particularly flexible. In this way, you not only save the costs for a graphic designer, but can also work on your own design until you are 100% satisfied with it.

3. Material properties are retained

As already mentioned, the term “print” is not really applicable. Because unlike conventional textile printing processes, sublimation printing does not leave any coating on the fabric. This makes the printing technique truly unique. Because in this way, the material properties of the textile remain completely intact, which is very advantageous, especially for garments. If we look at the sports and outdoor sector, for example, the printed fabrics remain optimally breathable.

4. Very good durability

Another advantage that comes from the sublimation of the colour pigments is the high resilience and durability of the printed textiles. Because, you may already know the dilemma from flex print: the printed motifs are very prone to breaking or rubbing off over time. Especially after multiple washings or under heavy tensile stress (e.g. in sports), this problem often occurs.

The situation is completely different with sublimation or transfer printing. The firm bond between textile and ink makes the garments particularly easy to care for and resistant to colour fading. In addition, sublimation printing is resistant to UV radiation and other environmental influences, which also makes it very attractive for outdoor sports use.

5. Both large and small runs can be produced economically

With most conventional textile printing methods, the costs increase with each additional motif or the complexity of the motifs used. This can be very expensive, especially for small print runs. Since sublimation printing is a digital printing process, any number of motifs can be added free of charge and even small runs can be produced very cost-effectively.

6. Fast production

Thanks to state-of-the-art technology, a transfer print does not require any post-treatment or special waiting time. When the textile leaves the thermal transfer press, it is immediately ready for use. Thus, almost no other textile printing process can keep up with this production time.

7. Designs can always be reordered

Very often, sports clubs, for example, are faced with the problem that the collection of the current jersey has already expired. Re-ordering jerseys then becomes unnecessarily complicated. With sublimation printed jerseys this will not happen. Because once the design has been created and saved, it can be reproduced on demand at any time.

8. Sustainable textile printing process

Last but not least, sublimation printing is also much more environmentally friendly than other textile printing processes. Not only is there no need for binders or solvents, the water-based inks are also much more environmentally friendly than all chemical-based inks. In addition, the outstanding durability of the printed textiles is in the spirit of sustainability.
