Time for another round of GP troubleshooting!
Ok, there is a chance this has nothing to do with the particular film I'm using but maybe it does. I'm printing Fixxons films on an Epson 7890 printer, letting the films sit to dry (sometimes overnight, sometimes for a half hour or so...doesn't seem to make a difference either way), and exposing screens that have been coated 1 on the print side, 2 on the squeegee side and left to dry for at least a few hours (sometimes overnight...again, doesn't seem to make a difference). The issue I'm having is that after exposing for 11 min under weighted glass with my 1000 watt halogen bulb the films are sticking to my screen. They do come off without affecting the emulsion and the screens are perfect, but the problem is that some of the ink from the film is sticking and staying on the emulsion rendering the film useless for more screens down the road. This kind of sucks because I do a lot of repeat printing for a friends coffee shop....multiple orders of the same thing a couple times a month. Having to output new film every time is a huge waste of time and money.
I am assuming that the culprit is probably humidity....or heat from the halogen. But I'm not sure. My studio is not very humid...its actually rather dry. Of course I cant say that for certain, I don't have a humidistat, just going based on the fast rate of wet screens, ink, etc, drying in my studio....pretty darn quick. And the fact that leaving screens to dry overnight doesn't seem to make much difference.
I did recently change the bulb in my halogen...the old one was pretty old....maybe the new one is getting hotter? I'm not sure. It doesn't seem to take any less time to get a proper exposure with the new bulb anyway.
So, does anyone else ever have this problem? With Fixxons film, or with any other brand? I'm trying to decide if I should tough it out with this roll until its gone and spring for a roll of a more name brand film next time around, or if I should buy a better roll right now given the amount of epson ink I'm wasting (not cheap stuff).
