I have started my first sublimation order for shirts. I am using the Hanes cool dri shirts, and the print color looks great. the problem I am having is that the edges of the paper are showing on the shirt. I am pressing on white and light blue. They both seem to show a box around the image. I tried cutting the image and it shows the lines of the edge of the paper. what do I do? Is it a pressure issue, or what? I have to have these 75 shirts complete in 3 days. Help!!!
