This is one of those things that is killing me, and I hope one of you guys know what the hell is going on.
Ulano LX660 Emulsion
230 mesh screen
Water based inks
23 LPI halftones (so they're kinda big)
I print with a quarter and a nickel taped to the bottom of each side of the frame for a little off contact
on the first 20 pulls of the squeegee its fine, but after that, the smaller dots, well they just disappear.
The gradient effect is destroyed, and the missing dots print empty spaces like gaps in an otherwise perfect smile
could this be because Im not exposing long enough? I dont know, because all other aspects of the stencil are perfect. its not a brand new screen, so I dont think its a degreasing issue. I looked into screen hardener, but it seems that using that means you cant reclaim the screen, and thats out of the question. any ideas?
