There’s a small shadow on my black text. Why is that?
When we print a very dark solid colour against a white or a very light colour background, there may be a small amount of shadowing that happens when the paper is pulled away from the fabric. This happens since the fabric is still very hot when the paper is lifted and some trace amounts of dark ink may still continue to transfer. While some very minor shadowing will pass the print quality check, if there is too much shadowing the print will be redone.
