Coating Screens And Emulsion Tips

- Colin shows what to look for when coating screens to get the best emulsion coverage. Not all emulsions respond the same when coating screens, some emulsions require adjustments in pressure and speed, depending on the emulsion thickness and the type of mesh you're working with on your screen. The end result: a nice glisten that makes a great stencil for your next screen printing job.

Good video sir . what kind of emulsion u can recomended to use to make halftone sir ..thanks u
Any emulsion I recomend will be based on the exposure unit type that you have. Do you know the unit and bulb type?

Hey just starting to screen print. Was wondering if you could recommend a dual cure (plastisol/WB) with a forgiving exposure time. I am doing it at home with a 300 watt bulb. Have both 110 and 230 mesh screens. Great vids btw! Thanks.
Hi! Thanks for the kudos! For a bulb like that, we our WBP emulsion as its the most forgiving emulsion we carry. You will have to do some GOOD testing to find your sweet spot. Definitely use the 21 step greyscale calculator to help dial in your exposure times.

@@Ryonet oh man thanks for the response, and so fast! I’m in Portland so already looking to will call some WBP and SGREEN degrader today 🤗
Hey am using a HOT PINK pantone PMS 813C....why am I seeing the white underbase when I print with this ink??....i
was using a 230 screen and the printing supply ppl say I should be using a 110 - 160 screen....it still didn't work 😣😞😥 and I have a good feeling it wasn't but try it anyway didn't work....i think the ink is too thin I feel like they may thin it out too much....what you think?? 😞
Are you saying that the pink looks to thin when you print it? Not the color in the bucket?
How do I prevent beading when the screen is drying? I get a lot of dried droplets when the acreen is dried.
Sounds like you may have more emulsion coated on the screen than you need. Try tipping your scoop coater back a bit so less emulsion gets applied and you can use an ink card to scrape off any excess on the sides. Try making sure you have a good amount of air circulation as they dry, this should help! Give us a call if you need more help!
Is there anything else i can use to coat the emulsion?? If i don’t have the scooper thing you have
What's up @RodfromGOD?! i've seen people using squeegees or long plastic scrapers to coat. If i'm in your shoes, i'm going to find something that will allow me to apply a consistent coat w/o putting my screen at risk (ie. sharp edges,etc..). Hope that helps.
How much does it impact the stencil if you dry the coated screen t-shirt side up? I don’t have a drying rack yet, so my work-around has been using a clothes drying rack, but there’s no way to put the screens on there t-shirt side down…
Ideally you dry your screens with the t-shirt side down as this will create a thicker emulsion on the t-shirt side of your screen which can help make a cleaner, crisper print but you may not see a huge difference when drying with the t-shirt side up. If you can, make a spot in your place where you can set small cups at each corner of your screen so you can have the t-shirt side down and still have airflow underneath. In the end though, don't let this detail stop you, you can still make great prints!
@@Ryonet Thanks for answering! That is helpful to know. I propped a couple screens on a few pieces of wood this last time, but cups/glasses would give them a little more airflow underneath.
Does it matter if you don’t put emulsion on all sides? This has been a debate within my peers.
Some like to cover the screen entirely with emulsion, others say you don’t need to.
Hi @val Good question. there's some gray area, but overall covering both sides will give you a more durable stencil and incapsulate the mesh threads better. If I'm a manual printer, i may be able to get a way w/ a coat on one side, but never as an auto printer.the stencil would not be strong enough. Also, there is some correlation between your thickness of stencil and the quality of the deposit of ink on the garment. I would argue that a thicker, more durable stencil will also create a smoother and cleaner print. hope that helps. THANKS!
I wouldn't dare to spread a screen like
