Description
• Photo emulsion is best for creating detailed or photographic type stencils for screen printing. • Speedball’s Diazo Photo Emulsion is a 2-step process where the photo emulsion needs to be “activated.” • To activate, the photo emulsion sensitizer needs to be added. • The sensitizer is a very thick oil and needs water to create the right consistency for adding it to the photo emulsion. • The sensitizer bottle will feel unfilled, but don’t worry it is not empty! • No need for a light safe environment or darkroom! Mix photo emulsion under normal light conditions. • Set contains 1 each of the following: 6.6oz (195ml) Diazo Photo Emulsion; 2.12g Diazo Sensitizer; 8oz (237ml) Diazo Photo Emulsion Remover and Instructions. • Conforms to ASTM D-4236. • The jar contains a dried solution. Please add water and shake so that the dried material dissolves into water and turns green.

so far so good
I power mixed the emulsion with a drill and got a lot of air bubbles - IDIOT. Next I had some trouble spreading the emulsion, but, that was due to my test screen not having near enough tension, and, it was just my first try. After my little mess with the test screen, I coated my production screen, A professionally built and screened aluminum frame. That came out pretty good. You need to be able to fully spread the emulsion and then screed off any excess quickly. I made a nice clear plastic spreading tray but ended up using a 3" plastic bondo spreader with a sharp point to finish spreading and then screeding off excess emulsion. I am making smaller screens though. Spread front of screen, then screed, spread back, then screed. Inspect your screen, spread more, then screed off excess from front side and back side. Press the screed into the screen pretty hard, if you are getting a proper thin coat, you wont get any lines from making multi spreading and screeding passes. I will tell you this, watching youtube videos with pros spreading emulsion with a single front and back pass is pure fantasy. You are probably NOT going to be able to do this with one perfect spreading pass in front and one perfect spreading/screeding pass in back, so don't even worry about it. Be ready to do multiple passes front and back, but be ready to get it done quickly. This process works 100 times better if you got a professionally done and screened frame with the screen stretched super tight. I stretched my first frame myself and found it tough to get high enough screen tension, then I bought a cheap but good aluminum frame with pre-streatched screen and OMG, it was so much more easy and better. Spread and screed off your emulsion quickly, as if you take too long the emulsion starts to thicken up and then it gets very hard to screed off the excess. Thankfully, I found this out on my first test screen so I got right to it and finished quickly on my money screen and it came out PERFECT. Nice even thin coating and when it fully dried it was exactly as needed, no more thickness then the screen itself, and, that is exactly what you want. If you get excess thickness on your coated screen you will have problems with excess paint loading when doing your screen printing. Excess thickness was the problem I had with my first screen, not made with emulsion, but with a sheet of sticky vinyl with letters cut out. It worked OK, but was hard to get a nice prefect thin layer of ink/paint on my products as the vinyl, seemed thin enough but in reality, it was thicker then it should have been and when the screen thickness was added, it was laying down to thick a layer of screen printing ink [paint]. I'm so looking forward to using my screens made with this emulsion, screen printing should work so much better. ~

Reliable Results from Trusted Brand | Kit contains all chemicals needed
I'm a hobbyist screenprinter, and basically just print once a year to make t-shirts for my family's annual reunion. I used to struggle with emulsifying and exposing correctly, but since I switched to this Diazo Kit last year I've been very happy and have had minimal problems. The kit comes with the photosensitive agent that must be mixed with water and added to the emulsion, which very easy to do and is not light sensitive during the prep, (which is a huge plus!) It says you can even coat the screen in regular light - although I haven't tried. Working under a yellow safe-light bulb, I've gotten good results and even coating with the Diazo. The emulsion itself is easy to work with: goes on very smoothly, dries quickly, and exposes evenly and pretty accurately to the included time guide. Also included in the kit is a large bottle of screen cleaner, which works exceptionally well to clean out screens that have been left emulsified even up to a year! I always run out of emulsion before screen cleaner - it seems like they could balance the proportions of the two components a little more evenly. My only complaint about this product is it's a little pricey compared to buying in bulk or purchasing the chemicals separately. I can get about 2-3 full screen coverages per emulsion bottle which is great for a hobbyist not printing often, but may use up quickly for someone printing more. Speedball Diazo Photo Emulsion Kit

great screens
Very easy to use photo emulsion. I use this with water based inks and can get some nice screens burned. I like that the Dazio is very versitile in how you want to burnt he screen. You can use a light buld and a pie dish if you want. Personally, i prefer to just run out side and count to 30 in the bright dresert sun. I get a perfect exposure every time. I noticed that the only pinholes I get on the screen are usually caused by errors on my part. bad negative, etc. Other emulsions I've used always gave me tons of pinholes. Not dazio. Dazio cleans up off the screen fairly easy. I've tried other pro level photo emulsion chemicals but I don't need to buy a quart everytime I have a project. So, this dazio fit the bill too in that regard, it's enough for 4 good 11x16 screens. Price per volume is a bit higher for the Dazio compared to other commercial-grade brands but I like it. Great screens and just the right amount I need for my random projects.

Easy to use Emulsion. Perfect for beginners.
An easy to use emulsion. If you’re new to silk screening, buy their light, their screen, and their emulsion. Then find yourself a good scoop coater and a piece float glass (available at Home Depot) about the size of the screen. The scoop coater doesn’t have to be Speedball brand. Mix the diazo and shake it up really really well. I usually let it sit for 2 hours shaking occasionally throughout that time. Then add the diazo to the bottle, mix in the diazo and you should have a dramatic color change in the emulsion to green. Scoop coat and dry your screens. Then put your transparency on the screen (keeping the orientation in mind), put the glass on top so the transparency does not move and then expose with the light and their 200 watt photo bulb. With this configuration it’s usually 7-9 minutes.
