hey, I am fairly new to screen printing. I have been doing a lot of paper printing lately and I was curious about emulsion coating.
I have a 230 mesh count screen and up to now I have been only doing 1 emulsion coat. I'm working with more halftone images now, should I be doing 1/1 coating or more?
Is there a relationship between halftone count and emulsion coats.
Thanks for your help.
high solids high definition emulsion is key to making good halftones. but there are a million other variables. Well, at least 10....
really, 2 coats each side...gotta try that next time...i always do 1/1 and clean each side with scoop coater. i always thought less emulsion for halftones.
I'm surprised to hear 2/2 Andy. Maybe it depends on the emulsion ?
emulsion, mesh, coater, technique.
they all come into play.
there's a test pattern you can do in the book. gives you 9 variations on one screen, including some wet on dry buildups. Interesting the results.
The thicker the emulsion the better the deposit of ink which usually means better halftone dots.
2/2 wet on wet? or do you wait for it to dry and then recoat it?
What this guy here said.

We mostly coat 1/1 though
