The OP is looking for an emulsion that does not require diazo.He wants the fast exposure of a photopolymer, but the water resistance of diazo or hardener without adding either. Really tough search for this one.
I thought the Xenon Nova and CCI HXT were options along with the Aquasol HV/P? Depends on your definition of long runs I guess but haven't there been printers here that have done 3-5K pieces with these emulsions above without using the optional diazo? We've done 1500 on one set of screens without diazo and we didn't do more because that was the size of the job.
How long is the hardener step for everyone? Is it something that adds very little time to our pre-press discharge procedure. Spray on, wipe down both sides, sits in front of a fan for a minute or two and we're press ready. Others may spend more time on this step and the fact that we aren't doing thousands of pieces may be the reason this step being hurried hasn't bit us in the A-nus. Thoughts?
