Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I'm thinking I may have gotten a bad batch of the black. That stuff builds up so bad on the back of my screens that i've just completely stopped using it. I was getting at least a nickles width worth of buildup on the back of them and it was damn near impossible to clean it off without having to really scrub it with some screen opener and a soft scrub pad (it tore right through shop towels). The white is nice, has quite a bit of puff in it from what i'm seeing though.

The white is nice, has quite a bit of puff in it from what i'm seeing though.Can you remember about what the temperature inside the shop was at the time or has it happened across a large range of temps? I've been using the black for about a year and we print black first down all the time and only had buildup under conditions that were very ripe for buildup, high temps inside the shop, low mesh counts, high humidity, tacky emulsion to start the process, next to a flash, etc.
i just emailed Joe about this, as we are doing more testing today.We are trying the white again today, but in the past we've had a really hard time with this ink.on our g3, i have this ink going through a 200s screen, with a yellow smiling jack, but it has to flood and print so slow in order to clear, and our pressure is between 40 and 50psi. so high!
