Powderless DTF printing. What is it and is it any good?

There is a lot of hype around powderless DTF printing at the moment. In the nutshell, instead of having to apply and cure DTF powder, you pre-treat the t-shirt instead, like you would for DTG printing. You can then stick a freshly printed transfer straight onto the garment, skipping the whole smoky powder curing process. This makes a lot of sense logically. It’s a standard procedure when it comes to DTG printing and because there is no powder layer, in theory you should get a very soft and breathable print. DTF and DTG inks are very similar and can sometimes be used interchangeably so why wouldn’t it work? It turns out there is a major flaw to powderless DTF however. Washability.

Let’s run a quick experiment. I used 2 types of tried and tested DTG pre-treatment (Epson and Resolute (Kodak)) to pre-treat a Gildan 64000 t-shirt as you would for DTG. A different pre-treatment solution on each side. I then applied a few wet transfers straight out of the printer to each side followed by more transfers that were left to dry for a few hours after being printed. Surprisingly, wet ink smudging was not that big of an issue. I then pressed the transfers at medium to high pressure and an exact temperature/duration as instructed by the pre-treatment manufacturers. Same way I used to press our DTG prints. The t-shirt was then left to dry for a few days before going into the wash. I did a quick scratch/stretch test and it seemed like there was hope. The transfers held well. After 1 wash cycle at 60C without using a dryer, the transfers became very fragile, despite surviving the actual wash just fine. I could easily rub holes in them with even mild pressure. The corners became easily peelable. With such poor durability, I don’t think these t-shirts would be sellable. Even though the overall feel was incredible.

Here is a short video showing the results:

I speculate the main difference is that when you spray ink onto a pre-treated t-shirt using a DTG printer, not only do you apply more ink in total, you also spray it right onto the garment, allowing it to be absorbed by the t-shirt fibres, creating a stronger bond. When you apply a DTF transfer on the other hand, it acts more like a thin sticker and sits mostly on the surface of the garment.

I can see powderless DTF becoming a viable printing method in the future but for the time being it just does not pass the wash test. We may need better pre-treatments or a non standard application process. This is something I’m still experimenting with, keeping my fingers crossed.
