At First Edition Screenprinting we print and apply thousands of transfers. Over the years we have developed methods to improve our batting average. Our production rate with cold peels is now very near that of hot split and the scrap from hot splitting of cold peels has been eliminated. It weights approximately 5 pounds. We apply it to the transfer for 3 seconds cooling the transfer enough to be peeled immediately after.
Time is easy.
If your heat is inaccurate or inconsistent you do not have control of temperature. If your machine has warped platens or a bad pad, you do not have control of pressure. If you cannot control these variables, you are going to lose.
