Residual Emulsion Clogging

Thanks for all the help.

I love GeePee!

Blow a clean fan onto the screen to dry it. The fan should be clean because you don't want it blowing tiny bits of dirt into the screen. That creates pinholes.

Also, if you have a t-shirt drier, we put the screens on top of it. It evaporates the screen dry way quicker.

As soon as I'm done rinsing, I place sheets of blank newsprint over each side of the screen to absorb the excess water. Once I peel the damp newsprint off, no more water drips. Then into the closet or onto a rack with a small clean fan blowing on it.

I use a windshield squeegee to remove excess water after rinsing out, helps speed the dry time also.

Scumming...I like that. Happens to my screens all the time too. I wash out, dry complete, then expose the screen for a minute or so in the sun to lock down anything that was under exposed the first time. I then go back to the booth if there's any traces of the transparent scum and wash it out again. The second wash gets everything perfect. Lost time is the bummer in this fix.

Or you could turn the fan around and have it blow air in the opposite direction. This is what I do and it is actually more effective at drying screens.

Also, with the t-shirt screens, you can just place it right on the back of the fan.

I'll have to try that.

Longer Washout (with focus on entire screen, not just design) + Dry Horizontal + Dry In Dark = Problem Solved!

Once I find that everything looks good and I have no traces of emulsion in my open stencil, I set it back on my exposure table to lock in anything that may have been underexposed. Three screens down so far and everything is working fine. Thanks again!
