So I have continued to try this paper with less than perfect results. To recap, I had purchased some 100% cotton fabric from Hobby Lobby to test on. The darker colors transferred extremely well. The lighter colors not so much. So I though, there is not enough ink being laid down to activate the emulsion. I did a couple of trials like turning off high speed printing which laid down more ink. Absolutely the same results.
Because I was curious, I took the last half sheet I had available and pressed it onto a Gildan shirt I had lying around. The results were horrible. Now it was a dark shirt so I didn't expect to be able to see the design but I still expected it to transfer under identical parameters but it didn't. This sucks because if I decide to stick with solid darker colors and use this paper, I had hoped that my cheap learning method of using the fabric would prove out the settings so I wouldn't have to waste shirts. Not so much. I get that the plain fabric has a tighter weave but the results shouldn't have been that different in my opinion.
I gave up at that point because I was frustrated. That was last weekend I think and I have not tried since. I have 5 sheets left to do more tests. I am probably going to go down to 1/4 sheet trials so I can get the most out of it before I run out. This is tough at over $2.00 a sheet.
My next trial is going to be with a different image on a regular shirt. I will use a white shirt this time so I can duplicate what I saw them do at ISS Nashville.
Depending on the results of my next test, I think I am going to have to try one of the powder coat options out there. I am curious to see the difference. It is also much cheaper.
