Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
Quote from: Vastex on July 17, 2013, 02:02:04 PMHey everybody. We're glad to see all of the conversation on exposing with LED so I'll chime in a little bit. We have done a lot of testing on our new E-2000 before releasing it and have compared it with a 1200W metal halide and high output fluorescent tubes. We used Ulano (Orange and TLX) along with Kiwo (Polycol Onecoat and SWR Red) during our tests. We have also tested Kiwo Polycol Onecoat with diazo added to make the stencil waterproof for discharge inks. We used a Kiwo exposure calculator to get precise times. We also use the glisten method (3 coats shirt side and 2 coats ink side) of coating screens which give a much better stencil that 1/1. I'm not sure about testing a dual-cure on a 110 mesh as Lawson tested because most screen printers would be using a much higher mesh for that. Our dual cure tests were on 230 and 305 with the 305 easily holding 85lpi halftones and very readable 3pt text. Our times were comparable and often quicker than the 1200W metal halide with better detail and 5-10 times faster than fluorescent on dual cure and about 15-20 times faster on single part emulsion. If anybody will be at the Printwear show in Long Beach this weekend, head over to our booth and check out the unit. We will also be printing a 4 color process (Kiwo SWR Red on 305 mesh) and a discharge print (Polycol onecoat with diazo on 156) all exposed on the new E-2000.Thanks for stopping by Vastex boyif there is not too much to ask, for those who can`t make it to the show could you shoot a short vid of the new exposure unitthanks welcome to TSB

I`m wondering if M&R will ever enter the market of LED exposure units.
What ever happened to that independent guy that blazed the trail of LED exposure units. He was super confident and it came off cocky but he sent the unit to Pierre and I thought it all checked out.
