Introduction to Photo Emulsion (Part 1 of 5) 

hello and thank you for purchasing our emulsion system. yes, if the color does not turn grassy green, more Sensitizer is needed. it is likely a small amount of the paste in the Sensitizer bottel was not fully mixed and that is negatively impacting the ratio of Sensitzer to Emulsion. Without the full amount, it is unlikely the product will expose correctly.

Yeah..same problem for me. After a couple of tries to get my emulsion to match the shade of green in the video I ended up cutting the bottle apart because I was able to see what looked like dried diazo. When I cut the bottle apart, I couldn't even scrape it the dried diazo loose and I was never able to get the emulsion to turn that shade of lime green so didn't make it past this step. Reached out to Speedball customer service. We'll see what they say..

Same for me, cut open little bottle... and hard lump I used exacto knife to cut up. And fork on plate to mash up. Still blue (bummer didn't get green)

@@ebajda1 Contact Speedball customer service. They'll ask you some questions and send you a replacement right away. Only took a few days to get it. When I got the replacement, I was careful to add water to the diazo bottle and waited a couple of hours, then shook it up as directed in this video. Everything worked according to plan then.. Good luck!

He is awesome!

Danielle Espinosa no throw it awat

Yes since the screen is a mesh the emulsion will drip through just like when you swipe ink through it, a good coating of emulsion is needed to fully block out the screen in areas you do not want to print, so it is best to swipe the emulsion while over a sink.

this studio is one of our favorites to shoot! Happened to be the old studio of our friend @linobill!

It is not required to do so, but a product like Speed Clean can be used to degrease prior to the first coating if preferred

More for the NEXT printing project!

@@speedball_art hey question...so im able to get my print on the screen AFTER the light BUT when i go to add ink nothin will touch the shirt.... do u know wat im doin wrong?😔😞😕

EL_XICANO408 you possibly let it sit for too long so light was able to seep under your blacked out areas and harden the emulsion underneath? not sure tho :)

@@CAVEMAN_408 we'd be happy to try to troubleshoot this with you--please contact our customer service team at customerservice@speedballart.com so we can assist!

Sorry to hear that the mixing didn't quite work. There is only a tiny bit of sensitizer in the small bottle, but that's all it takes. And if you still are having trouble with the process, please feel free to reach out to us at info@speedballart.com

Hi, thanks for being interested in our products! Please visit speedballart.com to learn more and purchase the supplies you need!

Hi! We recommend following the instructions listed on packaging for the best results❤️

Hi! We recommend using the LED lamp that comes with the kit for the best results!

Brian is using a 250W BBA photoflood bulb. Any UV light is usable to expose a screen, but all the calculations featured in our instructional resources would be specific to the BBA lightsource. Many use the sun's light to expose screens, but the trial and error that is needed for alternative light sources has many preferring to rely on the lamp provided in our kits to minimize frustration

@@speedball_art I don't see it being used in the instruction video. I'm trying to get into this for a few t-shirts. Not using it makes it looks like it doesn't work well. thanks for clearing this up.

in this video, Brian is using a transparency from our 6-pack of transparency sheets and those are specifically made for use with inkjet printers. thanks for watching!

Hello! It should be okay as long as the screen has been thoroughly cleaned with cleaners!

@@speedball_art thank you 👍🏼

Hi! Yes, you would need to mix all the sensitizer in for the emulsion to work!

Most of the sensitizer will be stuck to the bottle it’s so frustrating.. I had to cut the bottle in half to get it all out.

The 2oz / 8.85g paste Sensitizer (#004578) is required for use with the 26.4fl oz Emulsion

@@speedball_art so the same 2oz whether you have an 8oz bottle of emulsion OR the 26.4 oz Emulsion?!

@@Macfish1163 The quantities for the Sensitizer are different for each. The 8oz jar of Emulsion uses the smaller 2.12g of Sensitizer paste, while the 26.4oz Emulsion uses a 2oz bottle that contains 8.85g of Sensitizer.

The sensitizer is a drier paste of sorts. There are times that age or storage conditions can negatively impact the condition of the product, though. If you have added water and stirred vigorously with a stir stick for several minutes and have not seen the results featured in this video, we encourage you to reach out to our Customer Service team for assistance.

@@speedball_art mine had brown flakes when i mixed it

@@veve7103 oh no! that can happen if the product has exceeded its shelf life. If you reach out to our Customer Service team, they can help you with some replacements - customerservice@speedballart.com

Same thing happened to mine...im guessing the sensitiser was expired. It was hard as a rock inside its bottle​@@veve7103

We're sorry to hear that! Our technical team is the best resource and can be reached at info@speedballart.com. Thank you!

@@speedball_art thankyou, I'll send though some photos

Same here :(

These products are guaranteed for two years from the date of manufacture if stored as directed. While most of the products are good well after that date, it does sound as though the Sensitizer may have expired.

That's a very good question. Once mixed, you can store the photo emulsion in the refrigerator for up to 4 months.

@@speedball_art thank you!
