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

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.

I am an absolute beginner, so far I have perfectly coated 2 screen with no problem. I did fail at one screen but that was my own error. I dropped a big blob of the emulsion down onto the screen. Someone said this is not beginner friendly, but I have had no problem and I don't believe that I am just naturally skilled at this lol. The emulsion dries fairly fast and the image burning worked fine. Spraying the image out is easy and doesn't take long. I recommend a spray bottle for it. I did it first with a shower head but that was hard. I have coated a total of 3 screens and probably still have enough for one more. So it lasts pretty long. Overall this is a great product and I recommend it.

I've used this before with no issues but the last order July 2026 is defective. As others have noted, the emulsion doesn't cure properly, whether burning under UV light or in the sun. Not a problem with the transparency or my experience level, it's the emulsion. Was hoping this was better than Speedball but now it seems to be just as unreliable. Might be worth it to pay more for professional brand.

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.

When you read reviews and you see ones that just give it 1 star and say it just junk and doesn't work at all, it should tell you that either they happen to get the one bad batch or they just don't really know what they are doing. This is my first attempt ever at screening. I read a researched a lot and took my and still made mistakes but the results of the first screen worked great! The biggest mistake I made, and I assume many others are too by reading the reviews, is applying too much emulsion on the screen and not coating it evenly. I watched videos and read other instructions and they talk about how it will drip; you should NOT be applying so much that it drips!! As you can see my first attempt dripped all over the place and the coating was spotty. I was able to get it to work but that needed a lot of improvement. Heavy and uneven coatings also cause a lot of issues with proper exposure. My second attempt I used much less emulsion when applying it with a good brush and just kept doing all-up, all-down, all-left, and all-right strokes until it was very evenly covered. It's really hard to see in the second photo because I was still in the dark room (not exposed yet), but the coating is almost perfect. Not one drip. It will take a lot less exposure time also. Bottom line, this stuff works and works well if you know what you are doing. Nothing I hate more than reviews that are tainted with negative results making me afraid of a product when in actuality it's just their own deficiencies. I do appreciate those real reviews and those that take the time to write a real review.

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 gave it 3 stars because maybe the product was not at fault. You see, I couldn't quite get the correct time exposure dialed into. Kept having a lot of washouts, except for one time, even after exposing for 2 minutes on a warm sunny day at mid-day. I also had the same problem when using my LED UV light source. So, I prefer the Ecotex emulsion over this one. Ecotex is more reliable and the stencil strength of it feels very durable, even with minimal coats applied.

C'est facile a utiliser, et l'ecran est de bonne qualité, par contre le pot indique au'il faut changer le couvercle, alors que c'est 2emem couvercle n'est pas inclu. Pour le moment le produit est dans son pot d'origine avec le couvercle d'origine, j'espere qu'il marchera bien la prochaine fois

I did find this difficult to apply...but it was the first time I used it.recomedyou buy some cleaner to remove after use

Arrivato prima del previsto. Prodotto buonissimo.. consiglio..

Have bought this specific emulsion multiple times now and have had good results with screens and is pretty easy to work with. Lasts pretty long too once mixed if kept in the fridge

I honestly wanted to trust this product, but after three failed attempts and watching thousands of youtube videos, reading how to on reddit forums, even watching their tutorials the emulsion did not work. I followed the exact processes of everyone, even one user on here that said to leave it for 10 hours, I I applied three coats evenly, let it dry till it was not wet to touch, exposed under the right conditions with the right lamps for the right time and even longer on the third time - even left it for an hour and it did not burn. I am not touching this product again, i have lost a week's worth of waiting for this too dry and $65 down the drain quite literally.
