It's time to revisit the emulsions..., I have been using the CCI HXT Blue for 4/5 years, no problems, and I will continue to use it, because is cheap, perform very well with the LED exposure, with plastisols, long runs, good reclaiming, no problems with all the chemicals( screen wash, screen opener, etc.), But...
on the water/discharge side, We haven't found "the" emulsion, We have tried several (ready to use, diazo, ...) but without luck, always some problem..., We have tried "hardener", but sometimes in the long runs are not enough... We have LED exposure unit and We have metal halide(MSP3140).
Let me know, What are you using this days...
Thanks.
