I'd be interested in a thread discussing the nitty gritty details of how people are getting such insane screen open time.  If I'm printing matsui through a 230 or 280 with any kind of halftones, and I don't soft flood, it will dry-in in less than 10 minutes.  That is mixed with water and printgen.  Even with a soft flood I get dryin around 20-30 minutes on detail, and the screen is a mess from the ink settling through due to gravity.  An hour is simply not doable.  I understand the idea of fully clearing the screen, but in practice even with a clearing stroke, it isnt 100% clear, and that invisible 1 or 2% that didnt fully clear adds up over time causing blockage.

The better DC inks in which Glycerin and other products are added to the homogenization process are designed to re-wet themselves after 2 or 3 test prints.

Start one! Splitting these threads can be really tough sometimes.
That rug really tied the room together, did it not?

Start with looking up "hydroscopic"

*hygroscopic...

Steve, I've seen no mention of you using an "S" thread mesh?

We've been using a 140S for the discharges. (Haven't had any fine detail just yet) For the very rare straight waterbase, 99% of them on towels, it's a 110S. Unfortunately, since it's spring, and we all know that means crazy busy, we can't spend as much time as we'd like, too much to get out the door. And, I will be looking up both Hydroscopic and Hygroscopic, because they both sound right, LOL.
