discharge emulsion question

[balloonguy]

do all emulsions for discharge diazo activated? Does anyone make a cap film that can be used for discharge/water base? I get a call for it 3 - 4 times a year. I don't want to buy a gallon every time. This one is very short run. It is 36 pieces.
Thanks.

There are photopolymer emulsions rated for discharge and waterbase that can be Post Exposed and will hold up fine especially for short runs.
You could also try using a reclaimable hardener spray. 
For a 36 piece run you may be able to just run the emulsion you have with a hardener or post expose it if it's a photopolymer.

Take a look at KIWO MultiTex.

Take a look at KIWO MultiTex.

Yeah, KIWO MultiTex works good. Also Saati PHU 2 works good as well. You could always just buy a quart of emulsion & bust it out when needed. Most photopolymer emulsions have a good shelf life.

Thanks. I will try the saati. I can get it very easily. It is such a small run I just want it to be easy.

Be sure to post expose your screens for optimal resistance.

I would not discount quarts of Green Galaxy CryoCoat Emulsion which is marketed as good for discharge, plastisol, and waterbase without the need of a hardener.   

I have used it on low production discharge runs and I don't like to buy a two part emulsion that has a short life after mixing.  I use it for both discharge and plastisol.  It's very cost effective.   

And our Danny Gruninger has posted his testimonial (paid? lol) of the product with various test exposure results

A reminder....don't forget the exposure unit as a variable. Flourescent, halide, and LED units may often yield different results.

Thanks for the info. I normally leave my screens in the FL sun to dry. Will that work for post expose or should they go back in the exposure unit?

[tonypep]

Depends on the weather! Either way post exposing and hardening is just good insurance.

Chromaline ChromaTech DEX will work in that case. It`s an SBQ emulsion.
