Title: Peeling DTF Transfers
Post by: Frog on May 10, 2021, 03:50:36 PM
Okay, be honest. Who's ruined one by peeling too soon while still too warm?  :o
I've developed a new system to keep me more honest by pressing a few and then going back to peel and re-press.

we take them from the hot press right to a cold one and press it. The cold platen sucks that heat out in seconds so you can peel  / move faster. We are pressing a second time for 5-6 seconds on some items just because we are used to doing that with screened transfers. I have a few carhartts and rain coats with DTF full backs and I am beating the living piss out of them to try and make them fail. so far so good.

And yes, I pulled early once or twice.... :o

shut up Rob... ;D

I keep them in place with Stahl's blue heat tape, and find it leaves a little ghost that then disappears with the second pressing

We've pulled some warm and some we've pressed and just pull then the next day, no problems so far, but now that I say this I'll screw something tomorrow ;D

Been there, done that, but that's the learning curve. I just did some from TPRNT, and they came out really good at the recommended temp and pressure, 3 second initial press to get rid of moisture, 12 seconds at 310°, let it cool to room temp (or body temp seems OK too) then gave them the second press, which actually seemed to make them softer. But on a couple of jobs I needed to do some testing. The "boss" at Supacolor called and helped me dial it in on a problematic drawstring backpack. I've taken to order a few extras to test with. This is making a lot of customers pretty happy, no complaints on the "hand" at all. This seasoned and proud screen printer is selling a lot of transfers of late, as it gives the customers what they want.

Steve - Good to hear you are getting good results...  Frog - Let me know if you need any help or a few more samples to test different times & temps.

Just finishing up that second job, and it's working pretty smoothly. I'm pressing for 12, letting it cool, peeling, and pressing with a cover sheet another 8 or so. btw, the second pressing also gets rid of what initially looked like spitting, excess adhesive or ink.
I only wish you were closer.

Watch out. If too warm, the ink has not re-solidified and you'll pull it apart.

I initially had issues with sticky corners, but have since been using the craft / silicone paper with great results.  I have rarely felt I needed a repress, but to make sure things are 100% I press, peel and then pop the sheet back and do a quick squeegee.  6 months later my contractors shirts are still holding up well

Exactly. Same for us. Just because we can print a 5 or 6 color hsa print on 18 poly gym shorts doesn't mean you should. The product and pricing is great.

So can someone who has done this tell me the difference in repressing with the craft paper vs the teflon/silicone sheet?,  I heard one makes the transfer shinny the other matte finish.

With almost all heat seal that I have ever dealt with teflon sheet has produced a shinier look (though originally described as "the more screen-printed look), while kraft paper more matte. I often use baking parchment, and in fact, just did so on my last DTF job.
btw, years ago, Diane at Color Your World and I bonded over using texture sheets on vinyl. Similar to what is used on upholstery repair, the textured sheets impart the texture to the heat-softened plastic decoration materials.

I've been using baking parchment for the second press, it keeps it matte, and as someone else mentioned seems to make the adhesive flashing (for lack of a better term) disappear.

We are talking about DTF transfers. Which stands for "Direct To Film" or "Digital To Film" depending on who you ask. We started working with them about 1 year ago and offer them to the trade only at www.tprnt.com (http://www.tprnt.com). There are other companies that also offer them. You can also modify some Epson desktop printers to produce them.

I would like to thank the members of this group for support and feedback that they have given me. The state of the art for these transfers is changing very quickly. I think you will all be excited about what will be possible in the near feature.
