Discuss the various aspects of heat press technology. Transfer paper, inks, plastisol transfers, vinyl cutters, printers, commercial usage, durability, suppliers, etc.
I have just tried to use the jpss transfer paper set the press to 280df and press for 15 seconds as i had to bring the press back up it burnt the paper and the t shirt badly to the point where it melted the sewing on the seams lol
Set the heat press to 350 degrees F. Prepress fabric for a few seconds to remove wrinkle and excess moisture. Allow the garment to cool.
Place the transfer face down on the garment. Using medium pressure, press for 20 seconds. Paper should be peeled hot using an even motion.

what temp should i be using for when i try again
cheers
I think you are in Celsius and actually burning your gear at 536 degrees F.

Your temp gage is set for Celsius. 280* F wouldn't even be hot enough to get JPSS to stick and be peeled.

Agreed. Sounds like a classic case of C vs F.

i think you may be right thats what i thought it might be. it was that hot the paper did not need peeling it was burn onto the top plate lol. What temp in celcius should i use. I could of cooked a turkey under the press it was that hot.

Here is a link to a calculator. Use it to convert whatever temp you end up using that works for you from Celsius to Fahrenheit. It is goin to take some trial and error for you heat press.
I press JPSS between 360F - 375F and 10-15 seconds and the polymer still turns yellow on me. So if I ever use it I mask it with plain paper that I cutout the image part. Use the plain paper to cover the unprinted area.

Interesting. We press at 375F for 30 seconds and have never had the "yellowing problem". Granted, our shirts are always Gildan Ultra 2000 shirts. Perhaps it is the shirt.
There are a number of shirts treated with a stain resistant chemical. Heat turns the chemical brown. Even Gildan puts that chemical in a few of their upscale shirts.

I have to agree. Same settings, 375F for 30 seconds, and I do not get yellowing with my JPSS polymer. I use Hanes beefy, Gildan's ultra cotton and ultra blends, and Jerzee's 29. In fact, on the Jerzee's, the window is barely perceptible even though I am "looking" for it. That's right after a fresh press without a wash.

I have sent sample printed shirts to Neenah with yellowing issue. I was told the only way they can simulate the yellowing I have was to raise the temp to 420F. I was told that maybe my press is too hot when in fact the measurements I have with my press agrees with industrial pyrometer with contact probe that is certified by the National Bureau of Standards.
Funny thing is the batch that I bought from you form way back I did not have the yellowing problem. So Neenah asked me to supply them three sheets from the ones that I have. I was told that the transfers were fine and they tested different batches that they have. I was told they were fine too. So go figure.
Here is the readings that I have. The meter tracked from the time I turned on the press.
Kelly, please do me a favor. Don't change this to a link. If I may I want the pictures viewable with without clicking on the link.
Thanks.

i use JPSS too.
in my case, i get yellowing...but not on the t-shirt. I noticed the yellowing remains on the peeled off paper. which is a good thing.
also, if other's have not discovered yet, you don't have to peel off the paper (like lifting it manually from the shirt) manually. all you have to do is stretch the shirt on all directions and paper will come off instantly without peeling it off manually.
