About this item
- 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.

Diazo Photo Emulsion Mixing
|
|
|
---|---|---|
Preparing to MixSpeedball’s Diazo Photo Emulsion is a 2-step process where the photo emulsion needs to be “activated.” To activate the emulsion, sensitizer must 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 big advantage of Speedball’s’ Diazo Photo Emulsion is there is no need for a light safe environment. Simply working under normal light will keep the emulsion from premature exposure. |
Mixing the Photo EmulsionFill the sensitizer bottle approximately ½ full with water (tap or distilled water works just fine.) Recap sensitizer bottle and shake vigorously! A craft stick can be used to scrape at the bottom to ensure all the material is stirred and dissolved. Open the bottle of photo emulsion – it will be bright blue. Carefully pour the mixed bottle of sensitizer into the bottle of photo emulsion. Stir well with a stir stick until all the sensitizer is thoroughly mixed into the photo emulsion. |
Green Means Go!The color will change from sky blue to a grassy green when the Photo Emulsion has been correctly mixed. The Photo Emulsion is now activated and ready to be applied to a screen. Store any unused emulsion in a cool, dark place. The shelf life, if refrigerated, is approximately 4 months. |
Preparing the Screen
|
|
|
---|---|---|
Coating the ScreenThe fundamental goal of coating a screen is to thoroughly permeate the mesh with the emulsion without overly saturating it and leaving emulsion dripping off. Lay the screen horizontally to dry in a dark place for a minimum of 4 hours. Cupboards, closets, empty drawers, etc. are all great places. |
Exposing the ImageThe amount of time it will require to properly expose an image will depend mostly on the light source. A larger, brighter light source will require less time for a good exposure. A smaller, dimmer, light source will require more time. Speedball makes this easy by offering a lamp and photoflood bulb sold separately. Suggested times for exposing with the lamp and bulb can be found in the Instructions and Tips Guide that is included in each kit. |
Washing Out the StencilUsing a spray nozzle or hose, apply a forceful spray of water to both sides of the screen until all unwanted emulsion is gone and the stencil/image can be easily seen. Dab the screen dry with newspaper or towel (Do not rub! The emulsion is still wet), and leave it to dry fully. |

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.

Ultimately the exposure I tried did not work as the emulsion just didn't set. I'm guessing it had "gone bad" or weakened with age.
I bought the Diazo emulsion kit and it worked just fine, so I know my lamp/setup/etc. wasn't the problem.
I've made some successful prints using the inks and screen contained in the original kit, but I think the rest of it was just too old. Buyer beware I suppose. Thank goodness for Amazon Prime shipping! This kit saved the day.
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.

I would suggest ordering it from anywhere else! Tracking number didn't work, NO communication from seller, and took a month, less 2 days to recieve.
Love the product, but hate the service!!
Update: ordered it again and this time it came in under 2 weeks. With Covid affecting the mail service, I'd say that's pretty good. Still cant say the service improved, as I had no need to contact anyone this time.
