We were suggested to use baby powder and worked like a charm. Just spread a little on the print side right before you tape your film to the screen and expose - helped a lot and didn't notice any pinholes which was my first concern. You may have to clean your glass from time to time to removed any small clumps of baby powder that may group together after a lot of tries. At like $1.00/bottle, worth a try, as it worked for us and at least one other shop when we used chromablue.
