I FINALLY got a successful screen done....2 in fact! I found the problems as well. 1. The images I'm using aren't dark enough and it's taking more time to burn the screen, which can be over burnt. 2. The screens need more time to dry. 3. Using enough ink and the right ink-the Yudu ink seems to be too tacky and dries way too fast which means I have to wash the screen every 2 shifts and then dry it again. Ugh...no thanks.
