The screen shouldn’t dry upwards. You want the emulsion to evenly dry. Lay it flat with the T-shirt side down. I prop mine up by putting cups in each corner of the screen.
Thanks. I have the same light as yours but didn't realize the glass was a UV blocker. My fist attempts bombed until I saw your setup. Followed your steps and my 1st successful screen print on a T-shirt 😀 Thanks for sharing !!
Thanks for share... I use to work in a big industrial screen printing shop some years ago, I have project to start a small SP local business. Your tips are so practicaly, low price and easy to do.
Great Video! I've read about screen printing, and had the things to do it for a long while. Your video helped to to plan very clearly how I will set up my things in my dark little garage, and I thank you!
quick question what wattage is your light? i was planning on using just a 500w halogen but a uv light is a good, much faster option just not sure how much juice i need.
Hi, thought i would share. I started screen printing 2 days ago, took weeks/months prepping getting all my info etc. This video helped me so much thank you. So with the specs of your exposure unit, i made the same one but i only have a 20w light (20W, 1600LM, 4000K, 230V-50Hz), and my exact exposure time is 1 hour, 2 minutes, 30 seconds. Thought this exposure time might help someone that only has a 20W light.
Greetings from South Africa. That's really a good job there. I'm actually amazed by your homemade screen burner and am wondering if you could help me with the plan. Wish to build one like yours.
Nice video, very instructional! Thanks! but the title should be How to burn your screens in a shop or work place to print somewhere...hehe! I mean, just wondering who might have all this equipment in a normal home? hehe!
Love your videos. I've learned much. In fact I built an exposure light exactly like yours. Which, brings me to my question. How do you figure out how long to expose the emulsion? In this video you timed it at 2 minutes and 30 seconds. Is that the perfect time? What happens if I expose it longer? Thanks for the advice. Bart
Thank you. That's a great question. I printout this document and use it to time test the emulsion. Over time the light will become weaker and if you keep the emulsion for longer it will need some time adjustment. Use this doc and start at the 8 minute mark. Use something dark to cover the other times and every 30 seconds reveal more of the sheet until you get to the 30 second mark. Turn off the light and wash out the screen. Then you'll see the best time for your light and emulsion. static1.squarespace.com/static/5c22ebdd85ede1c92284f8b1/5c293f1d8a4134666a4881b1/5c293f238a4134666a488319/1546207011556/time-test.pdf?format=original
@@StudioMoxy Thanks for the time test sheet. I'm somewhere in the 2:30 to 3:00 minute range. Not surprising considering I use the same type of light source as you. Question: can you expose a screen for too long? As I ask that question it occurs to me that the correct time is a balance between exposing the emulsion just enough to harden without the light going through the black ink on the negative. Have you tried 3:00 minutes? Thanks Bart
Barton Yount yes you can expose a screen too long. When you do this, you will see that the screen won’t wash out. You’ll need to remove the emulsion and start the process over again. Just keep testing till you dial it in.
Hi Moxy, I would like to ask, which printer to use for create the film positive? Laser printer is good to this task or need other solution? What is your power of your lamp? Thanks!
Ok, so I'm watching this 5 1/2 years after it was made, but the first thing I wondered was, "Doe she not understand that black lights ARE UV lights!?" BUT.... she's not the first person I've seen do that.
After you coat your screen it should be laid horizontal print side down not against your wall what your doing may work for you but it’s not the correct way to dry a screen after it’s been coated, also depending on what emulsion your using you want to coat the screen 2 times on the outside and 2 on the inside so you have even consistency and it will help with exposing your screens. Just some pointers for you I screen print for a living been doing it 20+ years
Aren't blacklight bulbs NOT good for emulsion exposure since they emit UV wavelengths? I use a darkroom lamp that's a deep amber, opposite the UV spectrum.
Sure thing! They definitely emit in the UV Spectrum, so you could get some exposure bleed/ fade if it's in the 'line-of-sight'. (UV is very directional)
different wavelength. if it were the wavelength that would expose the screen, then they'd be dangerous in you nightclub, make sense? you can look at black-lights all day without issue or protection.
UVA Blacklight is used in nightclubs which is safe for skin exposure which i guess has little effect on emulsion curing the light she used for curing is giving you the UV wavelength that could harm you if exposed enough to it
I have another question. I hope you don't mind, but I find your site a great place for information. Here it is: Do you use tack spray? Or do you use something else. Seems to me tack spray would get all over the place and I'd like to avoid that. Any information will be appreciated. Thanks.
It does get messy. There's another product that does the same thing that you can spread over your platen with a card. Something like this pro bond would do the trick. www.anthemprintingsf.com/Pro-Bond-Pallet-Adhesive-p/pro-bond-pint.htm
The foam was from a craft store (Joann) and I didn't have to cut it because it fit the size of my screens. If you find foam that is not the right size at that craft store, they can cut it to size for you.
Hi! Thanks for the video. Could you let us know about the type of lamp you used here. OK OK! We could use high ultraviolet content light sources to get an exposure time of around 3 minutes. 1. Mercury vapour. 2. Halogen. 3. Metal Halide. 4. U. V. LEDs. From the oldest to the latest - Number 4. Automobile lamps could be used with matching ballasts/ starters so check with your hardware guy. The best is sunlight with parallel rays, but you could use red/orange dyed mesh cloth to reduce undercutting due to diffused or non parallel rays. Hope some can get started!
Sutdio Moxi:Really important video. The intention of sharing knowledge with others is appreciated. Thanks for sharing your knowledge. I have learned a lot from your video. I want more videos. LOL
Moxy, please help!!! I coated my screens and put them in my cabinet to dry. That was 2 days ago. Today, I opened the cabinet to burn them but the emulsion wasn't dry. Also, it had all coagulated in a circle near the center of the screen and there were drips. I followed the directions on my emulsion and I followed your video... I'm thinking maybe there was no airflow inside my cabinet and that's what kept them from drying? I'm thinking about washing them, recoating, then letting them dry outside of the cabinet with a fan on them? What do you think?
That's a good idea. It will take trial and error to get the process down. Humidity may have been a factor and lack of airflow. The emulsion may have been a bad batch, but you'll have to try different things and troubleshoot it to get it to work for you.
Hi! I'm thing to buy a screen printing press with register, l'm to began to do screen printing, l have small room, so don't know what printing press to buy what do you recommend?,l hope you answer thanks
Love the DIY video. One question: where did you get the foam that you painted black to put under the screen? Also what type paint do you use to paint it? Thanks.
Do you know if there is an adhesive that you can apply to the back of the stencil so that the finished stencil can stick to the surface you're stenciling on?
The stencil is a clear film with a black image printed onto it. It’s not your typical cut out stencil. So the light burns the clear and all the other parts and hardens the emulsion, then you rinse out what didn’t get hardened by the light aka the black “stencil” or pattern
It's like a paint. It is the Speedball brand and the product is a blockout liquid. You would paint it on and it will come off the screen when you remove the stencil with a power washer. It doesn't come off as easily as the emulsion with the emulsion remover.
Anita Ramirez I don't coat both sides. The emulsion squeezes through the screen, so I try to scrape it down with the coaster to get a thin even coat on the screen.
You must coat on both sides, then remove excess, again on both sides, to guarantee even covering and a thin layer. Then dry it horizontal, with t-shirt side down.
hey, not sure if any one asked this yet but what does the foam do? Why don't you just flip your screen around and place your glass on the other side of your screen with the transparency underneath?
Hi Yousif, The foam is to give the screen some support and also to block any light that might come from underneath that causes a ghosting effect. I suppose you could try to burn the screen the way you suggested, but I’m not sure how well it would work. Try it out and let us know how it turns out. Thanks!
I have problems with chromaline pc701 emulsion, I use a 500 w halogen light. I have been given it 30 seconds on every section from a sheet of ten. But at the end of exposure it didn't come out or falling ..help pliz
i bought screen printing kit and i got only 3 yellow/green/red color, and i dont have one of those that people mix with water and let it dry and then wash it etc........ do i have to buy one of those too ? what is it called ? tnx
It sounds like you bought ink (the red/yellow/green) which you will need when printing. But you need emulsion to make the stencil on your screen. You can buy emulsion at craft stores that sell screen printing supplies or you can check out the description of the video I listed the supplies I used along with a blog post. I hope those help you.
Did you make sure the UV cover on the light was removed? You may want to do a time test with your emulsion by using a sheet of paper and moving it every 20 seconds to reveal more of the image to see your exact best exposure time. Make sure the emulsion is new and mixed properly as well.
Okay, removed UV cover and new well mixed emulsion should work. You should now do a time test with your emulsion to make sure that you have the correct amount of time for your burn. It can vary from brand of emulsion to brand and also if your light is new/or old. The brightness can make a difference.

Hi
I have problem during exposure with halogen same as u did,Is any change in emulsion
Did you make sure the UV cover on the light was removed? You may want to do a time test with your emulsion by using a sheet of paper and moving it every 20 seconds to reveal more of the image to see your exact best exposure time. Make sure the emulsion is new and mixed properly as well.
Ya Sure I removed and I took new emulsion 😕
Okay, removed UV cover and new well mixed emulsion should work. You should now do a time test with your emulsion to make sure that you have the correct amount of time for your burn. It can vary from brand of emulsion to brand and also if your light is new/or old. The brightness can make a difference. Check out my blog for a little more detail about time tests on step 7. studiomoxy.com/index.php/2017/08/17/burn-screen/

what kind of light did you use?
Great work.
How’s your business still doing? I was thinking of getting started myself
Can use any bulb or only uv light?
zaw yeh it would need to be a UV light as the emulsion is light uv sensitive.
Studio Moxy Thank you, it can be any uv light?
I think so, but you'll want to test your setup as it may be different than mine.
Thanks for sharing, I'm learning.

What is the spatula used for
What mess are you using 110 ?
Howl well does the press you have work as far as registration?
It takes a lot of effort but eventually it will register.
What kind of screen do you use?
Aren't you supposed to apply emulation to both sides of the screen?
I think that the only thing that you can consider to do is apply some pressure on the glass against the frame
Other than that is a nice video 👍🏽
