Ulano RLX  very forgiving emulsion, can coat in daylight without killing the stencil. Hold halftones impeccably and is a good all around strong stencil.

Only downside is , burn time is a bit longer than most yet with a good exposure unit, you will not notice the time difference that much.

NuArc exposure unit

I'm using Chromablue only now.  I was using Chromablue and Ulano LX680 for detail work, but I'm getting good enough results with the Chromablue, I don't see a need for the LX680 anymore.

Nuarc 3140 Exposure unit.

I use Aquasol HV (blue), I use a Workhorse photosharp exposure unit (1000K) My screens are around 7 to 12 OEM depending on mesh. My exposure times are 18 to 25 seconds.

was using Ulano RLX but switched to a one part that has Freedom Image on it ( thier brand) for the same or maybe a little cheaper and its a one part. As for the table I have an old Plate maker turned upside down and a box with sides and glass top for the light table, 1k. I have about $75 in the unit and could not be happier :)

It's recommended that you use hardeners with it for waterbase and discharge. Did you try that?

Haven't tried a hardener yet as it hasn't been necessary for me for the short runs I do with wb stuff.   I'd like to try the non permanent hardener, which one is that A or B?  Where do you guys buy hardener?  How hard is the reclaim?

Sbrem, what do you mean by lack of latitude?  You mean it exposes too quickly?

MS Hardener would probably be what you want, it's designed for shorter runs and is more forgiving. The A&B Hardener is more for screens that are stored and used over and over without reclaiming.

Forgot our exposure unit, Richmond Screenmaker 4358 with 10K watt metal halide with light integrator.  I don't know our exposure times, we work strictly off of light units.  110 with a 100 micron EOM on yellow mesh with the Saati is about 10 light units but we are talking about a pretty thick layer of emulsion.  305 with a 15 micron EOM is 2 light units.  If I had to guess, each light unit is about 10-15 seconds.

I'm using image mate photopolymer for my plastiosol screens.(made by chromaline and is similar to chromablue with higher solids and faster exposure time) and I use dirasol from sericol for my waterbase/discharge screens.The dirasol is by far the best water resist emulsion i have ever used.

Using Ulano QX-1. It is a presensitized dual cure hybrid.  It is my favorite because it reclaims easily even if under exposed. If your emulsion is giving you problems in the reclaim room you might want to find one that does not.

We have two exposure units, both Nuarcs, an MSP 3140 and the Tri-Light 3kW.

another nuarc 3140 here and another Aquasolv HV user. It is my understanding that we could get better results with other emulsions, but its versatility is making it hard to switch.

Yes, we've won our share of awards, and yes, I've tested stuff and read the scientific papers, but ultimately take everything I say with more than just a grain of salt! So if you are looking for trouble, just do as I say or even better, do something I said years ago!

Right now its imagemate 521 and 701 on a AWT Prolight unit BL.... 701 exposes at 2 minutes and the 521 at 8 minutes.  I have to thank Homer for turning me on to Valley Litho they have the best prices I,ve come across so far on emulsion.

Is the 521 water resistant?
