I had to go out of town unexpectedly. My partner tried coating a screen for the first time and never washed the scoop coater. I returned a week later to find it with a thick layer of emulsion on the groove.

What's the best way to remove the emulsion? He used photopolymer Graphic emulsion.

thanks in advance.

Scrape as much off as you can then soak in water.

I use water and emulsion remover to clean my coaters.. I would expect that to work for you.

You might be able to start peeling it off but what did when it happened. I clean as much as possible and then everytime i coat the screens i put tape on the lip im coating with so i dont rip the screen.

All good suggestions.

And careful not to nick the edge if you scrape.

I sanded some off one of mine recently. Obviously just sand the emulsion, don't grind down the metal. Haze remover ate it up too.

Watch out with the caustic--I've trashed a few ends like that, it's like it makes the plastic brittle, and the little flanges start breaking off.

Luckily my suppliers are at least as nice as I am, and gave me more for free.
