Can i use regular desk lamp or should it be a uv light? And how long is the exposure for each kind of bulb if its applicable? I dont have a speedball bulb.
So will transparencies print on any inkjet printer? Should I consider asking the manufacturer if it is possible? My printer doesn’t say whether I can print transparencies with it.
I noticed with your instruction you said to place the ink side down of your transparency, but neglected to say you would have needed to print the image in reverse or else turn your screen over and do the exposure on that side. And I notice you reversed this problem in part 4 without any comment? Also would regular incandescent 250 watt flood lights work and do you have a video on testing different light levels/exposure times if you want to use sunlight?
Hi Steve--all great questions! In terms of your image, screen printing does not require you to print the image in reverse as is the case with relief printing. We mention which side of the transparency to place against the photo emulsion-side of the screen in order to maximize contact and opacity for exposure. As for bulbs, the information included in our video series and the corresponding instructional booklet that is available for download on our site is specific to a 250W BBA Photoflood bulb. Any use of alternative light sources would be experimental. While it is difficult to find, a 250W standard incandescent bulb would work, but again, the time used for exposure would not be something for which we have testing data. Sunlight will also work, but again, results will vary based on cloud cover, etc.
Yep, just learned by mistake. I was wondering about that and of course I learned by error! Thanks for printing a cat so you don’t teach proper methods! Ugh
I got your 46 piece screen printing set, followed all the instructions, and still I can’t get all of my image to wash out after exposure. I thought I was over exposing so I tried 7 minutes instead of 10 or 12 but still it seemed the parts that are under the light have the hardest time washing out. I thought it was also the light but it’s the one it came with. Idk what I’m doing wrong
Hi! If you are using our latest LED UV Exposure Lamp. The exposure time is actually 1 minute for most use cases. The lamp used in the video is an older version and required longer exposure time.
@@speedball_arthi! i tried multiple times exposing my screen with the 30W LED for roughly a minute and a half, but when i rinsed it all the emulsion came off each time. am i under exposing or what do you think could be wrong?
Is it possible to over wash a perfect exposure? Especially one with tiny details? And if the exposure comes out and washes perfectly, is there any harm in sticking it back under the lamp for a minute or so just to make sure what was cured really is cured?
it is possible to lose detail at wash out if the screen is slightly underexposed in areas. It is possible to touch up portions of the screen by covering the area with tape, or carefully painting some white out to the bottom of the screen and letting it dry. If the overall art is printing too spotty, or continuing to grow spottier, you may need to remove the emulsion, re-coat your screen, and expose your image again for a longer time.
Hi Jade! Yes, all the products featured in this video have been validated by an independent lab to be safe for household use and require no special steps for rinsing or disposal. Thanks for tuning in!
We would recommend a 250W BBA Photoflood bulb. Exposure time will be the byproduct of the size of your screen, so the best resource is our Screen Printing Instructional manual on our site. There, you can find an outline of the times coinciding with our most often used screen sizes www.speedballart.com/wp-content/uploads/2017/09/2017-Screen-Printing-Instructional-Booklet.pdf
Hi @speedball thank you for this. If i wanted to print an a4 frame within and a3 frame could i just lay a piece of black paper in the middle between the opaque sheet and glass? thanks so much.

Hello, I have a baslayr X1620 light box, can you tell me how long I would need to expose a screen..this is my very first time doing it so I have no idea and the only times shows are for the overheard light or sunlight exposure and I would really like to expose using the box. if you can help me that would be really great.
Hi, that's a very good question. We have never tested that light with our products before so it is hard to give you the exact exposure time! We recommend using our 30W LED exposure lamp but the light box you mentioned should work in theory as well. Would love to hear how your testing results are!
Hello, I made the purchase of the kit and my biggest doubt is the exposure time. I have a 24w led box and I would like to know if an approximate calculation can be made for the development time
That's a very good question. We recently redid all the exposure time and our product expert can help you with that if you don't mind reaching out to us at info@speedballart.com
We’d be happy to help troubleshoot your experience. Since what you’re describing can be the result of a few different things, can you please contact us at info@speedballart.com with some images of your project so we can help you adjust more specifically? 😀
Hi Lisa, that's a great question. Our lab has never tested the diazo emulsion with a UV light before. So I can't say it does for our products. But the method seems to work for some photopolymer emulsions. The tricky part is to figure out how long to expose the screen, which changes drastically based on the light source and types of emulsions.
So I got this screen printing kit, followed this tutorial, read the directions, but for the life of me I cannot get the emulsion to stay on the screen during washout. I've tried keeping it under the light for longer, raising the screen to be closer to the light, doing it during the daytime with ambient light also flowing into the room, making sure im not using too much emulsion. it just washes out every time. the light tha came with my kit does not look nearly as big/bright as the one shown here. could it just be that the light included with the kit isnt strong enough???? i used the entire bottle of photo emulsion trying this repeatedly and have yet to get a successful screen.
Hi! We are really sorry to hear that this happened! Normally, this is because the emulsion is underexposed or the emulsion and sensitizer are not fully mixed. But there could be other reasons too. We would love to help you troubleshoot the issue! Do you mind giving us more information on this issue by contacting info@speedballart.com?😀
@@speedball_art I jus realized that you are recommending a 250W bulb for the exposure, but the light tht comes with the kit is only 30W. That could be the issue.
@@TheUndergroundRave The 30W LED consumes less power but emits the same amount of light for exposure. It should work the same as the older 250W light.❤️
@@TheUndergroundRave Our product experts will take care of you from there. Thank you for contacting us! Again, I am really sorry that the project is not going as smoothly as it could be! ❤️But we will definitely help you get there!
@@1LyonsDenI have learned since then to just put art work on front (ink) side of the screen and expose from light above. If you using proper screen printing exposure unit then you put on back (tshirt) side of screen but not mirrored still. Hope that helps.
We have reviewed this with our technical team and they have indicated that a 100 incandescent bulb can be used, but the exposure time will need to be tested and will likely take quite a while (around 45 minutes). They all suggested using a step wedge test with increments of around five minutes at a minimum.
The bulb will emit UV light as the UV light is what is required to expose/burn the screen. That said, the levels emitted are not ones that require special accommodations
I know it’s been a couple of years, but I suggest trying your local pet store or farm store! They have lights like that for reptiles/amphibians and baby animals like chicks that use them for heat. As long as the bulb doesn’t exceed the maximum wattage for the lamp (and these lamps are usually pretty high wattage), it should be ok.
@@EverettPhifer yes,we would highly recommend the glass as it ensures consistent contact between your transparency and the screen. even frame glass will work as long as there isn't a UV filter of any kind on it.
Great question! Brian is using the bulb that we would recommend for this process, a 250W BBA photoflood bulb that is available in our kits and for individual sale. While a CFL or LED bulb can work, we do not have any testing available specific to either bulb; artists would need to conduct a strip test to determine the correct time. One point of note, since an LED bulb is designed to not emit high levels of UV, the exposure time will be much greater the bulb that we recommend (photoflood bulb).
The exposure time is a byproduct of the size of your screen and light source utilized. We have a great resource for use with our emulsion systems/light sources available for download on our site (Our Product Lines > Screen Printing > Screen Printing Kits>Literature Downloads found at bottom of page) if you are using our products. If you are opting to use alternative products for your project, trial and error will likely be needed for the time of exposure, but the resource above can likely be a good jumping off point for you
@@appliedknowledgepro Happy to help! The time for exposure will absolutely change if you opt to use an alternative light source--our recommendations would be specific to our LED lamp or our 250W BBA photoflood bulb, but the former may be a good starting point if the specifications of your LED light source are similar to ours. The only way to be guaranteed equivalence is with like sources, but again, should be a good jumping off point.

@@sierrajoyhouse8563 Brilliant! This is a great solution! The only thing for others to be mindful of is that many frames now have UV filters that may make exposing the image difficult--the cheaper the frame, the better :)
an alternative light source is absolutely workable, but will require some trial and error for distance settings and exposure times. we have a great video from Dominic Rapone on this channel showing how to use the sun to expose your screen--might be a good resource for you!
Hi, that's a really great question. Exposure times vary based on your light source and screen type/size. When using Speed Screens, the exposure time with the LED lamp shown (30W UV LED) is 1 minute while a 250W photoflood bulb will require about 4 min if both are set about 14 inches from the screen.
Yes, you can absolutely use sunlight to expose the screen. The amount of time will vary drastically depending upon weather conditions. There are some amazingly helpful apps that assist in calculating exposure times based on weather in your area and we have had great luck in recommending those for individuals who wish to use the sun instead of our recommended light source.
Depending on the lamp used, a burn time of 12+ minutes may be needed: www.speedballart.com/wp-content/uploads/2022/01/2021-Screen-Printing-Instructions-Version-5.pdf
The exposure time used will vary greatly depending upon the screen's size and the time of light source used. If you are using one of the screens offered in a Speedball Kit with our BBA light source, it is highly likely the image is underexposed and will wash out. You can find out more about exposure times by frame size and light source type through our site in the screen printing instruction manual that is downloadable there
@@shottyshottageek9819 You should be fine to just expose it for a bit longer. Success will vary based on a few variables, but we think it's absolutely worth a shot before you reclaim!
Since there are so many light sources available to printmakers, we're unable to offer exposure times for all bulb types. We recommend a 250W BBA Photoflood Bulb and can offer the times testing in our lab if using that light source. All other options would require some testing by the printmaker by trial and error. One note, most LED manufacturers offer that this type of light source does not emit UV light.
