"He who marches out of step hears another drum." ~ Ken Kesey
I used to use the same emulsion, if you want "925 wr" to work for you, you want to do a 2 over 1 coating, you want to let , "the 925 wr" to be in a room running a de-humidifer for no less that 48 hours. With that exposure unit, you are in no way exposing long enough, especially with film and glass in the unit, you want at least a 10 minute exposure, this will more than likely make you have to double print your film positive to make sure you have a super dense and opaque film positive. This emulsion, you want to let soak in a development tank for a couple minutes after exposure, it's very sensitive after exposure so any pressure water freshly sprayed on it's surface starts your downfall. THis emulsion also needs a long post exposure, preferably in the sun, and then last you will need to spray a hardener on the dryed post exposed screen. Let that dry fully. 925 wr was our go to emulsion for waterbased, and if all these steps are done proper, it will hold up like steel, buuuuuuuuut, skip one step and your done. That's the main reason why I was on a hunt for an emulsion that doesn't need hardners or long post exposing, and fell in love with HXT. It hasssssss to cook long. NOVA from xenon with diazo is also bullet proof, but needs a super long exposure. Aquasol HVP is a lot of people's go to, but you don't have a strong enough exposure unit for it, trust me, been there, done that. Key in any of these emulsions for discharge, w/b printing, is to NOT rush your process. I just wrapped up a job using a discharge base screen that is over a year old, has been used rinsed, racked and re-taped for re-use at least 20 times and is as perfect as the day I shot it. HXT all the way and still hanging in.
