Wiling off the excess emultion reminds me oof how i apply makup. Put it oon lightly thrn wipe most of it off. Perfect!
❤️
so well explained.
NOTE IF ANY OF YOU HAVE PROFESSIONAL PHOTO LIGHTS THAT WILL DO THE TRICK AS WELL DO IT ALL THE TIME AND WORKS LIKE A CHARM JUST USE ONE, THATS ALL YOU NEED
I recently bought the kit and my emulsion is teal? So i purchased more sensitizer and it still didn’t match “grass green.” With those results, I bought a brand new batch of both sensitized and emulsion…. This time the sensitizer was clumpy and wouldn’t mix (note: I used an electric mixer after this happened and screen still had spots of sensitizer and was nowhere close to “grass green”) Does the sensitizer expire? Do i even continue at this point?
I may have missed it, but if I put it in a dark oven, what should the oven temperature be? 😁
This always trips me up: is the image right reading or reverse reading when using this method? Thanks!
The design/image on the screen will be printed exactly onto the print surface. But sometimes, you need to reverse the text to be printed on the transparency film. This way the printed side of the transparency film doesn't touch the emulsion when exposing.
Can you help me find the exposure time for the a 30W LED for a 10"x14" screen?
did you figure it out?? pleassseee!! i'm trying to print with the same light rn 😊
@@heartshappedglsses I was sent this from Speedball. See page 16:
www.speedballart.com/wp-content/uploads/2022/01/2021-Screen-Printing-Instructions-Version-5.pdf
I read its about 7-8 mins. Check their website. It says the size of screen, the distance of the bulb to the screen and time
@Speedball do I necessarily have to let it dry for hours why can’t I do it for like some mins and see ? because that’s how the other people do it I’m really confused 🤔
we recommend hours in that it ensures it will be fully dry no matter the climate in which you are preparing the screen. you can certainly expedite the dry time with something like a fan if you wish to move to the exposure step more quickly. thanks for tuning in and happy printing!
Hello, I bought a large bottle of emulsion and a sensitizer bottle, I did it per instructions but the emulsion just came off after I attempted to burn a screen and my emulsion looks really blue, do I need more sensitizer?
I exposed with the sun in Arizona, for about 1:20min, and it just started falling of when rinsed with pressure wash. Will more sensitizer help with this?
I am sorry you are having trouble with the emulsion, it does sound like more sensitizer is needed, once mixed with the sensitizer the emulsion should be very grassy green for it to work correctly.
Hi I am trying to use the speedball photo emulsion kit but struggling with results. After exposing the screen it takes a very long time to wash away the stencil, eventually other parts of the screen are washing away whilst parts of the stencil are still not washing away. Very confused by what this means I am doing wrong? Tried another screen applying more photo emulsion but it dried gloopy, tried another screen with less photo emulsion and yielded same results. Using a Caydo 50W LED UV Screen Printing Light for 8-12 minutes positioned at the same distance from the frame as the width of the frame. Any advice would be much appreciated, thank you.
Hello! Please reach out to info@speedballart.com for further troubleshooting help. Thank you!
Is there any limit to how long a screen can be kept after emulsion is applied and dried, before I burn my image?
Hi, once the screen is exposed and properly cured, it can stay good for many months!
@@speedball_art again you missed the question. How long after you coat the screen and it is dry but before you expose your image onto the screen can that screen be held
@@lisavalentine492 we are sorry for not understanding your original question. we would recommend exposing the image within a week's time only if the screen can be kept in a temperature controlled and light safe environment for storage during the additional time
Also, can the film be just any cheap acetate from like Staples?
We recommend using Speedball brand transparency for the best results as it has a special coating for printing.
I live in Florida, can I use the sun to expose my image instead if a lightbulb?
absolutely! the sun is a great option, but with likely require some trial an error depending upon conditions. If you reference our Create in Place playlist, Speedball Demo Artist, Dominic Rapone, has an amazing tutorial on how to expose your screen using the sun. happy printing!
i live in new hampshire and use sun exposure! 60-70 seconds.
Is all of the dry emulsion solution supposed to dissolve in water?
Dry and exposed emulsion can only be removed with the photo emulsion remover.
Hello i was trying to wash off the emulsion but im having a really hard time. What do i do exactly because i need to clean 2 screens but not sure how to
We recommend using our photo emulsion remover to clean emulsion off screens.
@@speedball_art Thank you!
what do i do with the rest of my photo emulsion?
Save to use on more screens! Store in a cool dark place, the shelf life if refrigerated is 4 months.
Hey man so I just purchased the photo emulsion pack and my box didnt come with a sensitizer. Just a photo emulsion remover and the diazo photo emulsion. What can I do???
Hi! Sorry that happened to you! Do you mind contacting us via info@speedballart.com? We will help you if there are items missing.
so you don't have to coat the screen in a dark room?
correct! we do recommend you avoid direct light from the sun, but a dark room is not required.
@@speedball_art thank you so much!
@@ssolis22 happy to help!
How does someone troubleshoot the printing to the emulsion paper?
We can help with any troubleshooting at customerservice@speedballart.com!
in the video he says to let the emulsion dry for 1.5 hours, but the speedball book instructions say 4 hours, and now I'm reading to leave it overnight? which one is right
much of the time for drying will be driven by how thinly the emulsion is applied and what the humidity is like in your studio. The safest bet is to let it dry overnight if you are a beginner. If you are like Brian and have been coating screens for years and/or live in a particularly dry environment, 2-4 hours may be all you need. We always recommend erring on the side of caution with dry time and usually wait overnight with our own prints to be extra safe. Hope that helps!
I am having trouble printing on the acetate provided in the kit. Help!?
we'd be happy to help! could you please contact us at info@speedballart.com so we could learn more about your project?
How many screens can you burn with the kit?
You can always clean the screen and re-coat it for a different design!
Why arent u using a coactee scooper??
Coater
@@mikejones8667 Hi Mike! While we do have scoop coaters in our offering and agree they are game changers, this video features only the minimum required supplies to succesfully get printing to make it the most accessible instructional resource for the greatest number of viewers, especially those newer to screen printing. Still have a lot of love for our scoop coaters and the ease they can provide!
How long does it take to dry the emulsion?
Once placed on the screen, we would recommend giving the emulsion at least overnight to dry in an environment free from light. The ideal dry time would be ~24 hours.
what kind of bulb?
this video uses a 220W BBA Photoflood Bulb
Where can I buy this emulsion?
The best resource is our Store Locator on our site. There, you can search by the Screen Printing Product Line and by your postal code. These products are also available on many e-commerce sites if you prefer to order online.
@@speedball_art there's not any store near in Bosnia
@@bosanskipatriot1219 we're sorry we do not currently have a local distributor for you. we are actively trying to expand our international presence and hope we'll be available in your area very soon!
Let me tell you. I’ve ordered the kit. Follow these directions and NONE of it worked. Even exposing my screen to the sun didn’t help. It still washed away. Big thumbs down
We would love to help you troubleshoot further, please email info@speedballart.com, thank you!
