Anybody ever used old discharge as standard WB on lights? I've been meaning to try,
but am too nervous to do so on an actual job.

everyday!

The ink is really dead when it clumps like cottage cheese or separates in the cup.

Interesting.

By really dead do you mean as in not even fit for lights any more?

Here is a little tip: If you want to save your discharge ink put it in a air tight container and put about 10 sprays of water on top of the ink before sealing the container. The ink will dry it self out when the agent in the ink gets to the end of its life.  It will also suck the air out of the container. The added water will keep the ink usable and keep the top of the ink from crusting over.

I do this exact thing. 

Also chicken to try printing from the bucket 'o stank.  Well, not chicken about printing it but chicken about mixing it.

5 gallons a day that's about 110 gallons a month (22 day work month) Thats alot of cement blocks.

It really depends on what's being printed in a said week. We just came out of a 3 week period where its been all DC base with Plas top colors so the waste is low, now 3 weeks before that was DC all day on all machines and during those times, waste was high.

So yeah, that is a lot for us.  Years ago when we started with discharge we had problems but now its a 5 gallon every couple of months. Sometimes 3 or 4 months, sometimes two. We just have a few lying around closed up because I just don't have time to drive to the dump. But we do recycle all water base and plastisol every bit we can.

I think it can be mixed to a grey and printed again.  But, I think it will have to be re-activated.  Absolutely going to try this before disposing of our bucket. 

Coverage through a 150/48 is around 0.04g per sq inch, give or take + you need a minimum 200-300g just to run enough ink in the screen.  If you calculate, you get pretty close.  I'm keeping a log and noting usage wherever I can to get closer on other mesh counts but have been able to get it fairly close by gut. 

This is obvious but, the best trick is to mix you ink and only activate a little at a time.
