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.

Can I tell you just how wonderfully different this emulsion is?!?! Last time I ordered an emulsion I went “on the cheap” and have been a bit disappointed since - especially since I couldn’t reclaim the screens with a bleach solution [not that I’m recommending that]. But it was like magic when I used this again and the image areas washed out almost immediately. If you knew how “rustic” my process is - with a halogen work lamp to expose ink jet printed transparencies - you’d realize how receptive this emulsion in. As I keep it in the ‘fridge, I’ll be thrilled for at least three more months. Thank you for providing such a quality product!!!

Horrible emulsion, definitely don’t recommend ESPECIALLY if you’re new to screen printing! It’s not the right consistency, very watery and messy, doesn’t get evenly exposed, and takes FOREVER to dry. Its ruined 3 of my screens. Invest in better quality emulsion, or it’ll cost u more to work with this one and not even get good results. I’m so disappointed that I can’t even get a refund.

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.

This was my first experience burning screens and given my level of inexperience I was blown away with the results I got. I did two screens, one with a very basic graphic and another that was much more complex with fine detail. I fully expected the one with fine detail to come out all kinds of messed up but it turned out great.A few notes for other first timers:I smeared this stuff on with a Red Baron squeegee, didn't bother with a scoop coater and didn't have a problem, the trick seems to be to let it dry with the flat side of your screen facing down, that way you don't get runs. best way to do this is with blocks of wood underneath or by pressing thumbtacks into your screen's frame to use as temporary standoffs. I had the best luck letting it cure over night in a pitch dark closet.If burned correctly the exposed emulsion turns blueish while the stuff that will wash out stays green, so you can kinda tell if it burned right by the amount of contrast between the two. I used a cannibalized 500 watt halogen work light (UV glass removed, of course!) from HomeDepot rigged to a microphone boom stand roughly 20" above my work piece and burned for 13 minutes. My film positive was made from 2 pieces of laser printed overhead transparency sheets doubled up. With that set up, as soon as I removed the film positive I could see a clear distinction between the blue and the green.The wash out might take longer than you think, I sat there blasting away with a shower massage head worrying I'd over exposed the first one I did then all of the sudden my design just kind of appeared as the unexposed emulsion finally dissolved. If it doesn't seem like its coming out at first, just keep at it, it probably will.Totally satisfied with this stuff, will buy more and recommend to others.

So I'm giving this a 4-star review, but don't let that stop you from buying this product. I've just not had good luck with it, and I don't think most of that is the product. First I had a mesh count that was too high so I could never get a good burn that didn't wash out. This last time I don't think I exposed it long enough - that's on me, not on Jacquard. I re-coated the screen and tried again the next day, but it didn't burn at all, but my guess is that the space where I was drying it wasn't completely dark, again, on me.
