Speedball Art Products Diazo Photo Emulsion Kit for Screen Printing Frames

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. ~

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

This emulsion kit has a small bottle of sensitizer which you add to the emulsion to make it light-sensitive. That sensitizer should be a gel (in fact the bottle warns you it will feel empty), and you add water to the gel. I've used the same kit before and it worked perfectly well. Unfortunately this arrived and the gel had dried into a powder. I tried everything I could to rehydrate/reconstitute it, and it just didn't work. I mixed as much as I could, but it never incorporated and the emulsion never worked correctly. You could see the tiny flakes of sensitizer and the emulsion didn't turn the correct color when mixed. This can happen in person, too; I bought this kit off Amazon because the week before I bought it at a craft store, and the one I took off the shelf was also dry and unusable. If you order this, immediately check the little sensitizer bottle when it arrives. If it's a bone-dry lump, don't bother mixing it. I generally like Speedball products just fine, but this specific emulsion kit has a lot of problems if aged.

don't try to just mix a little bit, it wont work well. Mix the whole thing, just like the instructions say and this product will work great. Every little detail came through in my print. This stuff glides on easy and dries fast. Exposed with a fluorescent lamp for 45 min and then the stencil part washed off easy. Use only enough to cover your screen. the rest will store for several months. Happy printing!

The first thing you want to do is check that nothing has broken, spilled, or dried. The emulsion with be thick like glue and blue in color. The remover will be thin and clear like medical alcohol or bleach. Both should have cardboard gasketed lids and foil caps on them. The sensatizer (tiny bottle) should be either dry and at the bottom, or thick and at the bottom. If any of the sensatizer is spilled out of the little bottle (along the threads or down the side) send the kit back for a new one immediately. The product is good if you get it undamaged, but Speedball uses incompetant monkey powered robots made from scrap pulled from the Robot Wars set to package everything so check your stuff. As for operation, when the sensatizer is added to the emulsion it turns a good medium (not quite emerald) green and will turn back to blue after it cooks out when you burn the stencil. Look for a light-medium blue hue and the uncooked parts under the negative image should have a yellow, jaundace like hue to them. When cleaning out the emmulsion make sure to wipe up messes immediately as the emulsion leaves yellow stains on nearly every surface known to man, including porcelin and the steel rim around my sink. Trial and error for new users will happen, just don't leave emulsion in a screen for a long period of time if you don't want a permenant stencil, and clean the screen completely before letting it dry if you don't want a permenant stencil (yes the emulsion remover may make the emulsion impossible to remove. Don't ask me how, I failed mad science 101).

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.

I am a beginner and watched tons of tutorials online on how to screen print. I chose this product for the cost and quantity (I didn’t need a lot). It took a lot of trial and error but I figured out what works for me and my light source. I felt like coating one side and then pushing it back and forth through the screen, ending with pushing through the inside of the frame provided the best coating. Then I let it dry for at least 10 hours before burning the image on. The remover spray works super well! A little goes a long way.

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.

I spent a lot of time trying to figure out how to screen print on my own. I watched a lot of tutorials to try to understand the basics and I spent a lot of money on emulsion that i didn't know how to use properly ruining screens. I then came across a tutorial that showed how to use this package and so i gave it a shot and it works perfectly! I'm not doing anything complicated, so it's hard to mess up, but to really understand the development in how screen printing works, this bundler really worked well for me.

I thought, urgh, I'm not going to get much from this, but it's been going for a good while and I haven't run out. The emulsion/sensitiser is fab, works brilliantly, lovely and smooth to apply, and gives crisp printing. I've covered nearly ten screens (A4-ish) and still have plenty left. The emulsion remover works great, but the amount needed varies depending on how long the exposure has been burned. But I've been though nearly ten screens (about A4) and still have remover left. All in all, happy with product, and certainly would buy again when I finally run out!

I found the emulsion sensitizer empty and dry, i really so disappointed also i want to refund it plz contact me as soon as possible.

Good product

Me gusta mucho va muy bien para las pantallas de serigrafía
