We've been printing DTG for a few years now and just started with DTF. We use an Epson F2100 and get some great results (mostly). Issues we've seen are, 1. The powder always cures as a yellow color (except when just using white ink). This does not seem to affect the print on the shirts, the yellow ink does seem to transfer to the T-Seal sheet even though the instructions don't say it's not compatible. That said again does not seem to transfer back to the printed item. 2. We use a DTFPRO HEAT STATION V2 where it says the temp should be 248 for 120 seconds, instructions on the manufacturer film contradict these. I.e 300-315°F, 1min so not sure what temp and time to use. Get pretty good results but frequent "pin holes" in the ink. Can anyone advise on how to avoid those? 3. Issues with Magenta and White, we found recently any design with red or colors using Magenta print ok but when the white is printed over the top the red starts to bleed through the white. Tried leaving 60 second drying time between color and white with no difference. Hoping someone can help us out. DTF is a game changer and suddenly we can print on all kinds of fabrics and substrates, just have to iron out the bugs for those perfect prints.
