Help me understand why my emulsion is locking up

[CCI]

Ok. I think you need to look at another emulsion just to try and figure this out. It doesn't really matter who you get it from but a similar product would be best for comparisons. Unfortunately I have no experience with the emulsion you are using so I don't know what to recommend; is this definitely a 1 pot emulsion that you add diazo to for more resistance in discharge/water ?

Nova is an extremely high solids high detail pure photopolymer emulsion.

Eric have you thought that maybe the pump on your pressure washer is aged now, something to add to the equation...

I know this is an old thread, but I've not seen a resolution for this elsewhere.

Eric, is there anything you've found on this topic that would be helpful?

Let me say, I use CCI WR25 on everything. I see a little diazo staining, but it works for my needs without needing hardener for my shorter run WB Discharge and plastisol is easy.

I keep Gemzyme in the tank, and HR30 ink removal prior to that.

I don't get lockup, but my DIY solids filters clog up pretty quick.  I OFTEN have screens that dry COMPLETELY between ink removal and the trip to the dip tank for emulsion removal, since it is two completely separate steps in my shop. It doesn't seem to matter...but I *think* letting them dry may help preserve the Gemzyme's purity.

I'm just curios to see what you've found.

I have actually. It was a number of things, everything from chemical reactions to over and even under exposure. Once the CTS came in, we made this, and we started having this issues, we spent a good two weeks looking at everything we could.

Ultimately it took about 20 screens to lock in our step wedge test, but once we did, we haven't had an issue since. We've even switched emulsions two or three times since then, and have it all locked down in a matter of minutes now.
