What causes emulsion "tits"? When the emulsion was wet on the screen it looked good. When it dried it developed these tits.

Re: Strange Emulsion issue
looks like you were trying to coat too thick for the mesh count with that particualr emulsion.
On coarse mesh count you want a very thick emulsion like the textile PHW. You will still have to watch your coating thickness but it is more forgiving. Aalso try drying it in a cooler envirnment. The elevated heat can change the viscosity making it run a little thinner than normal.

Re: Strange Emulsion issue
Yes, and make sure your drying rack or whatever you use is level and has adequate air circulation; if there is nowhere for the humidity to go then you can see heavy spotting like this as well.
But I agree it looks like a more open mesh count which will require some thick emulsion to coat with ease. It will take a lot of emulsion too. Lower mesh counts tend to hold more emulsion and create thicker stencils.

Re: Strange Emulsion issue
Thank you! It happens from time to time. I can coat several screens at once and I might get one that does this. Always near the edge of the coating but not about an inch or 2 in.
