- When getting started with screen printing and screen making, there are multiple different options you can use for exposure. Ideally you would use an LED unit like the Quick Image or an automated unit like the LTS 8012 (Laser-To-Screen). However if your equipment has malfunctioned or you are just getting started, the sun does work. In this video Mick shows you how to use the sun to expose your screens the proper way. Comment below if you have any questions about exposing screens.

Mick used ChromaBlue emulsion in this video which has a wide exposure latitude. You can check out the user guide for each emulsion to see recommended exposure times, but we always recommend using an Exposure Calculator to dial in your exact exposure.

Right ta, so curious about this. I just want to set up a couple of screens to print on my own clothes, I'm not starting a business, looking at people calculate exposure times etc I just thought it was too hard especially as I have a brain injury and my maths not there anymore. My question is if using the sun is there a way to tell by looking at the screen or how it feels to know if it's been exposed long enough or is it the case you just have to trial and error it to find the right time?
Should be able to expose the screen for 45 seconds - 1 minute if it is a dual cure emulsion! Also helps if you put more pressure on the glass thats over the film. Have to think more like how a vacuum system works with adding pressure.
thanks for the tips Glen
Thank you very much for your video and clear explanation👌! I have a question, what does the time we give to development depend on? And does the screen number have anything to do with the time? I'm planning to reveal a small logo with thin letters to use with water based ink. Thank you!!!
The time to develop in the sun will be dependent on which emulsion you are using, so you will need to do your own exposure testing to see what works best for your set up
Does this only work with sertain emulsion type/brand?
I jave ecotex tex blue textile photopolymer emulsion
We’ve only tested our own emulsions, but it should work. You may need to play around with exposure time depending on how wide the exposure latitude is on that emulsion.
It works with Speedball emulsion.
