Speedball Diazo Photo Emulsion, 26.4-Ounce

This emulsion works very well. Keep in mind we are very inexperienced screen printers and are just now navigating our way around. We used Speedball's website for instructions on printing (there are several ways to print). Following their online guide really helped. The first run, we applied too much emulsion and it created dots or drips from pooling at certain places on the screen. Lesson learned, we moved on and applied it much thinner the next time and that eliminated the drips.Yes, they tell you this, but as a newbie, you think you're painting on enough but there is such thing as too much. We refrigerated the solution as instructed and it has performed well being preserved. Another hard lesson we learned is that screen cleaner is NOT the same thing as emulsion remover. We cleaned for well over an hour with just screen cleaner and it does not break up used/exposed emulsion. You need an emulsion remover to tackle this stuff. Though we did end up trying some home remedies to clean off the emulsion (lemon or citrus cleaners, hard spray (without a pressure washer) and scrubbing. We saved the screen for another use without purchasing the emulsion remover, but we will add that to our arsenal.This is a fun, albeit learning process. I now hold higher admiration for those screen printing companies that put a lot of work and apply the right methods to making a t-shirt. This is fun, but if you plan more than stencil screen prints, there is an art to it. Hopefully, we'll become artists with a little practice and patience.

always my go to emulsion. i get a nice clean and clear image. i coat my screens and then i burn them in the bright sun for only about a minute and they normally come out pretty perfect.

Been using this since i started screen printing at home. It is always on point no issues and burn time is low about 6 to 7 mins @ 500 watt buld. Always comes out perfect. I tried another product and had nothing but headaches. I will not stray from the path again. Awesome product for home use.

I'm a Prop and Costume replicator / fabricator and a lot of the newer superhero costumes have screen prints on them. I blew threw $200 in Emulsion from companies like ScreenPrinting(.)com, and a good bit was from shipping. Not only did I waste money, I wasted hours and hours. Speedball's Emulsion is fantastic! My screens come out just they way they should. My only gripe is we have to order Diazo separately. They need to take that off as part of the item's description. "Speedball Diazo Photo Emulsion." It just don't have Diazo. Period. That is, and always is, an additive. I burned my screens with a blacklight bulb for 9-10 minutes at 15" away. My screens washed out fast and clean.

Hey, I haven't used it yet, but all I got to say is I assumed it came with the sensitizer, because most of the other emulsions I looked at did. So, if you're thinking about buying this, make sure you get the sensitizer, too. You can't use it without that. Other than that, it came on time and appears to be all good.

This product is so well for screen printing and beginners. I love it so much

The one thing I didn't like about this is having to buy the sensitizer separately. It does alright, but not as good as other emulsions I've used.

I wish it mentioned that it was not already sensitized or was sold with it.I made 2 screens that failed before I realized I had to order sensitizer.
