Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
About a month ago I changed my old exposure unit to LED point light, now here is my question I've been using HXT emulsion for some time now with my old unit great emulsion but its blue/green and using it with my new unit I'm getting a slim on the print side of the screen at washout, which makes me bump the exposure way up.So I switch emulsion to CCI other product VPR which is pink in color same high solids as HXT, but the VPR burns in 10 seconds all the way through vs HXT at over 2 minutes. So does color have anything to do with using LED exposure lights? even the Ulano Orange which is orange in color works like a beast with LED or am I missing something here, my thinking is the color of the emulsion might play a big factor in LED exposure unit?
@ P, yes I did check the specs on the CCI VPR and it is a fast exposing emulsion, that could be the reason, don't get me wrong I like the VPR but I also like my emulsion just a little darker I find it helps register screens better for me with seeing the image.@ Rick 2.5 is some crazy fast exposure time, I'd think the screen would break down under long print runs, even at 11 seconds I'm doing now it still seems a little to long as the screen takes a little longer to wash out, but I'm afraid to expose any lower with full production.You guys are right got lot's more testing to do until I locked in on a certain emulsion
I think your going to need to do some exposure testing. moving to LED is usually not plug and play as your dramatically shortening your exposure window and different emulsions don't accommodate that as well as others. Honestly the 2.5 second thing still throws me back. Even consistent coating is critical also
