Ive been using LX660 for a while now, and its been good, but recently Ive been doing finer line and halftone work and I notice that the emulsion is not strong when its wet. When I wash a screen after a run, i notice that the details like the halftone dots and fine lines are peeling off. Now, I usually expose the screens, hose them down and then leave them out in the sun to dry. but in the winter, especially this winter, I cant. so they remain in my freezing cold shop to dry. could that have anything to do with it? also, any suggestions on a better emulsion for water based ink printing?
Ive been hearing that Ulano 925WR is the best stuff, and has been for 40 years. problem is, where can you get it in quarts.
still hoping that someone else has some other suggestion for water resistant emulsions...
We use Ulano 925WR, and it's great for our weird exposure methods, but I'm really curious about the Murakami. I've only ever used Ulano emulsions...is there anything I'd need to know about switching to the varsity-level stuff?
my supplier was selling me gallons, but giving me 4 smaller bottles of diazo measured for a quart.
So i would just pour off and activate as needed.
This is what I've been doing with Ulano QLT for a little while now. I got a quart of QLT to test out and weighed the full container before using any of it. Now I just order gallons and pour off into a quart container until I hit that same weight, add a small quart bottle of diazo and I'm good to go. Had to explain to my distributor what I was trying to do, but they got it after a little explanation and didn't have a problem sending the four smaller bottles of diazo instead of one bigger bottle. The Ulano QLT with diazo added is really tough stuff. Stands up to water based poster ink, water based textile ink, and water based discharge textile ink which is brutal stuff on most emulsion.
