Jacquard Photo Emulsion & Diazo Sensitizer 8oz - Light Sensitive Emulsion - Create Silk Screens with Photos Lettering Logos or Detailed Images

I feared I'd get an leaked jar of emulsion, but it was packaged in a bubble mailer, inside another mailer. I do find it odd the company doesn't put a seal on the top of the jar, like inks, and other things, so make sure you don't tilt when opening. As with other emulsions, I wish the container would have a half way mark or a unit of measure to go by. if it was made out of a material that is easier to see through that'd help. All mixed and ready to go.. Curious to see how this goes after using ulano proclaim for years.. I was out, I was in a pinch, and it is for a small project. I was able to coat 5 17x21 screens and had some left over.Not sure what to think. it went on great. I exposed it more than enough (500w, 15-20 min, from 18inch), yet after 1 clean up, the emulsion started washing off. I still have 2 screens coated and in the darkroom, but i now missed my deadline for the project. will have to research it more.. I guess I should have stuck with proclaim.

I'm giving this a five even though I have, what will sound like, a negative review. This stuff works, and probably well for what it is intended to work on, but I bought it for something completely different so, I want to warn anyone thinking of doing the same thing to STOP, don't try it.This stuff is made for silk screening, and having done a lot of silk screening in my day, I'm very confident it will work fine for that. It doesn't work on metal though.I knew this going in, but I really didn't want to buy a whole big roll of photosensitive film for the small project I am doing. This was cheap and I figured even though I wasn't going to use it all, it would be cheaper than buying a giant roll of film for twice the price and not using it.I don't etch all that much. When I do, I primarily etch copper or brass for model parts. I can go five years before that is necessary since I can also cast or machine small parts. But, very rarely, I need more detail than either casting or machining can provide; then I need photo etching.I thought I could make this work, but the emulsion just won't stick that well to metal, no matter how well you clean it or prep it. I tried 4x before giving up. I'm ordering the more expensive photosensitive film and trying to figure out what I need to silk screen. Also, this stuff really stinks (odor wise) and I got a head ache in a well ventilated room, so I used a respirator the next time and all was good. The thing is it does come out of the wash very crisp, but there is a very thin deceiving layer left behind and you can't have that with etching. If you try to remove that, with water or a brush, it destroys the detail (on metal). I'm sure silk will prevent that over washing from happening.

So I bought this for the price, I could not afford to have tablets imprinted with my logo for an upcoming convention, so I decided to DIY it. First, I tried the suggestion of one of the reviewers with the halogen work light removing the glass and cage, but that did not work. Then after a lot of cursing and youtubing, I purchased this UV light100W UV Black Light, Blacklight Flood Light with Plug and Switch, Black Light for Glow Party, Wavelength 385-400nm Purple Lights for Halloween/Christmas Dance Party Disco Night Club FluorescentKeeping my screens in a very dark place, and doing the setup in the dark, I had my light source 12" above my screen and exposed for exactly one minute. It turned out perfectly. I could not have asked for better results. There was also no wash off from the rest of the screen. I will buy this the next time I have to do screen printing.To the manufacturer of this product, thank you for making a good product at an affordable price.

Like many other experienced, no matter how long I expose there is no reaction to the light. I contacted Jacquard, and they confirmed that the sensitizer must have been bad. They check the batch number and it was not expired, so they said they would send me a replacement. It has been over 5 weeks and I still have not received anything. I reached out multiple times and get the runaround that the shipping department forgot, but they are sending it soon... and now they do not answer at all. If you do not want to replace your defective product, than just do not offer to do so. I will just go back to the other big brand that had always worked for me in the past. I can forgive a bad batch of product, but not a customer service that clearly does not care.

Easy to use, thick enough to stick well to the Speedball silk screen that I used it with. The design I was using also had some pretty thin lines (few millimeters thick) and the emulsion still worked well enough to print those thin lines.Also got this because I read reviews saying that it's easy to wash off with a basic bleach solution. I haven't tried this yet, so I can't verify, but it's definitely a perk to not have to use another chemical to wash off the emulsion..It's not 4 stars though because it took quite a bit of time to fully dry/process (like 6 hours). Not sure if that was my fault with the light I was using being too weak, or if the emulsion just doesn't process quickly.
