I am new to the transfer business and have relied on this forum for info so I hope you can help me!
I purchase JPSS paper due to the rave reviews on this board. I purchased it from alltransfers.com. I have an Epson NX415 for my printer. I also have a Sunie Seiki Heat Press 4801. I used 100% cotton white tshirts. I set the heat at 375-380 and pressed it for 30 seconds. I practiced this weekend and did not get good results. A lot of the ink remained on the paper and the ink on the shirt was terrible. I did do a hot peel. When I tried cold peel the paper would not release.
What am I doing wrong????
Please help!!!
Verify that you're actually getting the right temp. in your heat press machine and check the pressure, make sure you're pressing it firm enough. The recommendation is to press it firm so try that, then play with temperature, maybe gradually increase the settings 'till you dial it in. If you have an access to a temp. gun, it would be the best way to check if you're heat press is producing correct heat but if not, try playing with your temperature settings. Hope this help you, goodluck and enjoy your new venture!!

Check the temp. Temp gun from harbor freight is not accurate. I bought two and both were off by 20F to 30F degrees too high compared to industrial contact temp probe. I end returning both of them. If you have access to contact temp probe it is more accurate and reliable. Make sure it is the same or close within few degrees fahrenheit of the set temp. JPSS backing release when cold peel. I have tried with temps between 360F and 375F. Make sure the press unit is not centigrade also.

I just used the same paper at 360deg F and Medium pressure and came out great. Seems to be a pretty large temp range that JPSS works in.
I would have to agree with you on that remark as my temp gauge is at 175 celcius and I press JPSS for 25 seconds and it presses fine. The directions that came with my paper says 350-375 for 20-30 seconds but I guess it depends on your press as well.
Are you pressing the shirts first for 20 seconds or so? this might help.
I press each shirt at medium pressure for 25 seconds at 360 deg F then do a hot peal. I was having a hard time holding the shirt down while doing the hot peal because of the heat however, now I use a pot holder to hold the shirt down and it works great. Hope this helps.
I have not used jpss, but when I was doing light colored transfers I was using 400 degrees for 20 seconds and they worked perfect every time. The directions for my paper were the same as they are for the JPSS, so I have to agree with David here That a higher temp and shorter time worked great for me.

I've read about a really wide range of times and temps being used successfully with JPSS. I think Greg/gmille posted he's at 350*F or 360*F for like 20 seconds, Rhonda was at 400*F for 30(?), then the guy, Redline, he was doing near crazy stuff at 5 and 10 seconds, hahaaha! Well, he said it seemed to work, here's his fun and crazy thread on the various temps he played around with, and had some surprising success with. He was kind enough to toss in a bunch of pics and wash test results for us onlookers. Just tried NEW JPSS Mach I...whew! Super fast!
I myself am at 375*F for 30 seconds. Works great for me, and I pick the shirt up hot and give it a slight stretch to get the backer paper to pop off the shirt to start the peel for me. Someone else here did it, and I like it, too. Also helps offset that slight "skewing" I can get when peeling, if the paper is pulling the shirt a little too much, and pulling it out of shape.
HELP!!!
