L E D Green Screen Printing Emulsion (Gallon - 128oz.) Pre - Sensitized Photo Emulsion for Silk Screens, Textiles, and Fabric - for Screen Printing Plastisol Ink, Screen Printing Supplies

First of all, YES, This emulsion works.There’s bad reviews on this product, but after using it myself, I can confirm those bad reviews were left by inexperienced, impatient people. So if you have questions about using this product, keep reading.The BIG question is going to be about exposure time, so let me start by saying the recommended exposure time was way way off. I should of been smart enough to just do a exposure test from the start (hint hint) because recommendations are rarely correct, but I nailed it second shot so no loss actually for me.How I achieved success:I used a 1000 watt LED light for 4.5 minutes at 12 inches away. Recommendation was 15 seconds lol. First try, even tho I have a strong light, I knew 15 seconds seemed too good to be true, so I still went 30 seconds and the image washed out instantly. I than knew we were talking minutes for a good exposure. I felt 4.5 minutes based on the first run, and I was correct.I’m going to move the light down to about 6 to 8 inches, and burn for 4 minutes and I think that will be on the money.What you should know:This emulsion is on the thin side.Stir it well.It spreads nicely but the consistency isn’t perfect, some areas appeared to be too thin while other areas were on nicely. In the end it’s all covered fine, just keep an eye out.If you add to much, the emulsion will form drips on the bottom of your screen while drying, because it’s thin. I got quite a few drip spots on my second try, but even were my image was splitting a “drip” area, it DID still wash out fine, but it could have easily ruined the screen, so try not to let that happen.I doubt many of you are using a 1000watt light like mine, so I can only guess times for other lamps. With that being said, I recommend doing a exposure test, free to download and print online.A 500watt LED lamp at 6” away, I’m guessing would be anywhere from 6 to 10 minutes (my GUESS is 6.5 minutes). Any lamp smaller is going to be 10 to 15 minutes for sure. Anything more powerful is going to be in the 2 to 3 minute time I’m guessing.If you achieved a good burn in the recommended “seconds” please share your setup and details. Because I was really hoping this would be a 60 second thing with the lamp I have.

Original Review - Washed out of two screens that burned for over 30 minutes during exposure tests. Led light bulb. waste of money but thanks to prime I will return. Asked seller questions and he stopped responding. 11 sec burn time was the time in the instructions. No instructions in the box.Updated Review - Went and bought a uv led exposure unit (although I didnt want to) and the screen STILL washes out, even after a the quoted 11 seconds. So I burned for 2 minutes. No go, STILL washes out. Ive tried over 7 screens now and only one stayed. And that was at 2 inches at close to 4 minutes. Not happy at all but now I've used so much emulsion I don't know if I can get a refund smh. So upset but what can I do. And now I have a fancy exposure unit that I didn't want to buy. Only reason it got two stars is because it works at around 4 minutes (not counting the post hardening that's required to keep the screen from washing out in prints). I'd probably be better off with regular emulsion and a flood light (yay electricity bill)

Don’t listen to the noobs here.I have a diy exposure unit with some UV stops I got on Amazon and some particle board.The LEDS I have 30watts and about 6 inches from the screen. Strips are about 1 inch apart and they cover an area of 20 x 24.Screen exposes in 10-15 seconds just fine.It’s thin so be careful with it dripping while drying.

Whether Ecotex instructions or exposure calculator, blow out every time. Screens properly cleaned and degreased and dried before application. Emulsion dried for 24 hours in light safe exposure cabinet. Dual 50W LED lights at 9”. Going back to photopolymer emulsion.

Easy to use especially for beginners. Thick enough to easily handle. I used my son's 20 watt LED blacklight for 20 seconds. Washed out easily in my kitchen sink. I'm just dipping my feet in the screen printing world and this was 100% better than Speedball's Diazio
