I've recently started using S mesh. I'm really happy I made the switch. I got 135, 155, 180, and 225 to start off with. I want to order more screens/panels but held off to be sure I knew which mesh counts j liked best. I'm still a little on the fence, but here's my thoughts thus far.
135: I will be keeping a few for poly ink on red and other high bleeders. Possibly metallics as well.
150: underbase, white ink, the occasional one color HO p-f/p
180: top colors, dark ink on light shirts, highlight white
225: half tones.
I thought I'd be not using the 180's and using the 225's for the above mentioned. I'd like to try the 225's a little more. Thoughts? In printing everything manually right now, but the screens are all 23x31 and will be transitioning to auto at some point. I'm guessing the auto would probably have better pressure making the 225's better at that point?
