Long time listener, first time caller...
I was trying to get my first print done last night. I noticed that every time I made a pull, the paper stuck to the screen. Luckily, when I lifted the frame and held the paper down, it came off cleanly. But I can tell there's a 'haze' where the screen stuck. Also, the ink seems really thick.
I had spacers under the three sides not clamped into my hinges, approximately 1/8 in. thick. The screen itself seems to have enough spring to come away from the substrate.
I don't know if this is enough info to go by, but any ideas what might be happening?
