Hello. I have been having printing inconsistencies with Cotton Heritage 100% cotton black t-shirt. Some shirts will come out looking good and some will come out looking terrible. I don't change anything in my process before or after different designs. We also print on our own manufactured 100% cotton t-shirts and we have an amazing printing constituency on them. Sometimes we run out of sizes and we stock up on Cotton Heritage. I have boiled it down to an issue with the garments itself but I am not sure. I have printed the front of a Cotton Heritage t-shirt and it has come out looking not so great and so I run a print head cleaning hoping maybe that would fix an issues. Then I go to print on the back of the same shirt and it comes out looking equally as bad looking. But then I could go and print another Cotton Heritage t-shirt right after and have it looking gorgeous. Has anyone had this issue?
