Seriously. Poor exposures are so often over looked. I know some have their times/ units dialed in so tight it hurts. I like to think I'm one of them. But there are others that blow my mind. I can't use names, but I know a company that is doing both CTS and film, and they insist on using one "time" for every mesh from 86 to 305. Maybe I'm just using the wrong emulsion. I can push it a lot further than most, being CTS, but I wouldn't dream of trying that. Why knowingly set yourself up to fail? Screen making is the most important part of screenprinting. (maybe not, but that's what I say about every job someone does here, because to THEM it should be). Rant ends here.

One of my very first "innovations" back in the 80's was a vertical drying rack for the freshly-rinsed screens. We had a problem with slime until I replaced it with a horizontal one.

1. Properly expose -- it lessens the problem, but still:
2. Blot with newsprint -- don't wipe, or you will wipe slime into the image area.
3. Dry horizontally.

A properly exposed screen will also reclaim more easily & completely.

Actually a properly exposed screen can/should be wiped .
Slime=unexposed emulsion. We immediately drag a window squeegee across screens after rinseout and blast with compressed air. They dry in seconds

Agreed. I don't remember the last time I had scum in an image area. Oh yeah I do. The last time messed up and underexposed.
