The hybrid is a diazo/dual cure. The 10-30 sec times are photopolymer.We're using ryonets hybrid emulsion and getting 90 seconds. I've heard of others getting 30 seconds or less
Metal halide still give the same results for fine lines and halftones as a led if not just slightly better. The led advantage is low heat, low power consumption and less maintenance. This was directly from a M&R rep. I do agree the LED is the future. The commercial units though are over priced for what they have in them. I can buy more 3w UV LEDs and drivers for them then any of the commercial units for incredibly cheap prices. But this is nothing new in this industry.We have had our M & R Starligt for just over a month now.
There is not a better exposure unit on the market.
This unit has a lot more LED so that really helps in cutting down the exposure time.
With a one part emulsion we sre typically burning our screens from 4 to 7 seconds with about a 15 second draw down. We figure we are burning screens in about 30% of the time we had been previously.
As for holding halftones and fine lines you will find nothing better than an LED unit.
These clearly are the way of the future.
Check them out at an ISS show.
You will be blown away.
Just an FYI. M & R is so confident in the LED"S that they are offering a lifetime warranty on replacements if ever needed.
And no I do not represent M & R but it is the one I am most familiar with.
