Vinyl Peeling/Transfers cracking

[jibr]

We do both Vinyl and transfer on tshirts. We are told 302 degrees for 15 secs and the vinyl and 350-360 for 30 sec for transfers on opaque and standard tansfer for light colored shirts.

Problem one: vinyl is peeling
problem two: opaque transfer is cracking the transfers for white/light shirts no problem yet.

what do you suggest and what can I do different so this doesn't happen?

Thanks

Check your upper platen with an infared thermometer to make sure you're getting even temps throughout the platen.  What brand of press is it?

I've only had 2 issues with vinyl peeling...
1st was very, very thin lettering - and I peeled it hot... when I let it cool first, it was fine; and
2nd was because I put the vinyl on a ribbed tank (not noticeably ribbed - it was only a 1x1) -- but when my daughter put it on for the 100th time, the thin lettering parts have begun to peel
