What emulsion do you use with a LED exposure unit?
« on: April 26, 2017, 08:10:42 PM »
We were looking to try some different emulsions with our Starlight.
I have used Chromablue, looking for other options.

We use Chromablue. We could go to a PP but I just dont see the point, our current image/burn/wash out is a pretty constant cycle so faster burn would not yield more screens.

currently using chroma lime. Works for me, though I am getting an auto in a few weeks (Yay!) so I might start testing other options if we get more into sim process. Will be watching this thread.

T9 from Murakami with Diazo for the anti halation properties.

150S Mesh coated 1/1 very slow coats = 25 second exposure.  225S = 13 seconds........ 110 mesh = 40-50 seconds..... LED bulbs do not like "thick" stencils much at all.

Resolution is Really good.  I regularly get the 2-3% dot at 60lpi on 225S mesh.

We also have an iImage so we do not use glass with our unit.
Been in the industry since 1996.  5+ years with QCM Inks.  Been a part of shops of all sizes and abilities both as a printer and as an Artist/separator.  I am now the Ink and Chemical Product Manager at Ryonet.

Did you mean a different name.
Chromablue is a photopolymer.

I use ChromoLIME too. I just ran a price check and found online prices that range from $59 to $95 per gallon ???

I can't vouch for it's ability to hold detail (I don't get many halftone jobs).... but it exposes in 13 seconds on my DYI LED unit and reclaims well.

I coat 1X1 on S-mesh and can easily do 120 screens/gallon.

Also, it is fairly transparent after drying... which aids in registration, if your regi-system is not top-notch (mine is still a work in progress... homemade).

We have a private label product. 3 sec expose (not kidding) and does great with DC though we use the Trilite for that

May I ask what mesh count that is. We do only S-mesh here and don`t get anything like 13 sec. on our Vastex LED with the Chroma Lime coated 1/1 with sharp edge. If we would do 13 sec. reclaiming would be a nightmare.
