- The Basics of Burning and Exposing A Screen Print Frame.
Hello I’m Cam welcome to the screen print training videos series today we are talking about burning screens.
The process of buring a screen is pretty straight forward.
We place the film positive on the glass.
Then lay a screen coated with emulsion over the film.
Below the glass is a uv light source, we have a 50 watt led about 3 feet away.
The uv light hardens the areas of coated mesh not covered by the black on the film positive.
After it is burned you spray the screen with water and the areas of the screen not hit with light wash away to create a detailed stencil in the mesh.
Pretty simple right? Well Theres a little more to it that that, as a printer theres abunch of small technical choices that you have to make to burn the proper screen for the job your printing.
The point of this training vid is to demonstrate the basics and dive into the details of thoses steps.

Hit me with you exposure issues in the comments.
Any tips on where to buy a pre soak tank like yours?
Hey man, what kind of emulsion are you using? Any coating suggestions? My image might be under exposed if the emulsion peels off, correct? Idk :-/ haven’t had problems before, but I just switched over to clear transparencies.
Hey wondering if you could help me? I have just used a thin layer of Diazo screen print emulsion and exposed using a 250 Watt lamp for 10 minutes, as instructed. The image was burnt into the screen, however i really struggled when washing my negative out. After 10 minutes of pressurised water; nothing. The lighter green negative was on the screen, but it would just not wash out. I am going to try the process again but leave my screen exposing for longer, maybe an hour. My image is a bitmap photograph, and has lots of tiny dots, maybe this has an effect?
Hey what type of film are u using
What kind of light should you have on the exposure room? The emulsion can be exposed to sunlight while drying?
Omg ive been shooting the image out on the wrong side and it always blows out 😂 well, thats the point of you taking the time to make these videos right?! Thank you sir!
You are welcome my dude.
That bit about washing from the one side just made everything make so much sense. My God. I've blown out so many screens because of this...
How do I keep my wood screens from warping when washing? They haven’t yet but I’m sure they will
Welcome to 2019 Cam! UV LED FTW!!! 🖼💡⚡️🤘
Awesome video as always!
Good to see you back Cam
What is in the pre soak tank? having issues with having to scrub so emulsion comes off. Thanks, great vids!
Hey I have a issue with getting boogers in the screens after I dip my screens and washing them out also the edges of my screens are not clearing out. I don't have a pressure washer yet is that my problem???
Jon Szczepanski - stop blowing your nose around the screens lol. What do you mean by "boogers"?
@@jasonenz4238 emulsion boogers
I don’t like watching videos with hi-tech equipment
that’s a u problem
the part where you mention being 'pissed off' from accidentally blowing out your screen-- its super hard to explain this feeling to my boyfriend all week, I've just been nearly smacking my brain against a wall from fucking up my screen over and over and over hahah. I'm just glad it's a legit 'feeling'-- I was beginning to think I was getting irrationally angry 😩😭
hello friend a question what kind of printer do you use thanks
That old workhorse it the epson 4800. It's getting a bit tired but always pulls through. However it is time for an upgrade.
How do you find your lines per inch count? Thanks for sharing this info by the way!
Got the same question, 55lines per inch!? So how do you calculate that? So most thin line?
So if max is 55lines per 1 inch, so if you have 2mm line, then 55lines divided by 25-(mm in inch ) is 2,2lines per 1m, so if letter of line is 2mm so then 4,4 lines per inch? So 4,4. X 4,5 = 19.8 mash? 🤯🔫 buum fried brain 😂😂 how do you know what number to do with 4,5
If i have a 2mm letter or 5mm letters 20mm letters? How do you get lines per inch Them?
The main man is back :) thanks for the good tips.
Can anybody help me....im trying to do a small logo over the heart on the shirt.....i used a 110 and a 156 mesh and it wont pick up the tiny letters.....What am i doin wrong? Im putting weights over the screen when i burn it...do i need a bigger mesh screen???????
Bad ass! You answered several specific questions I’ve been having about my screens during washout. Thanks man!!
Suppose we have a single color logo with no gradient just solid shape ! Now we want to burn it on a screen do we export it directly or converting it into halftones is necessary ?? Please reply
This video was very informative!!! I was under the assumption that you needed a dark room!!
Nice organized shop. Good video, could be longer, not so fast. Keep them coming.
Is There A Special Type Of Uv Light When Washing A Screen Out After Exposure I'm Using A Red Rag Around My Light Budget As But Can Hardly See The Image I'm Washing Out Thanks From New Zealand Down Under
Why there is a piece o rope in the exposure unit. And how afects or improve the results ?
u still want 2 know?
What is the size and brand of your pressure washer? Very good video
Thanks for posting all these videos. Very helpful. I have a question though. Since you recommend washing out the screen from the outside, why do you not get the blow outs on the back as well? Thank you
Howdy Cam - i'm first! Great video!
First is always best.
great video! When you are ready to print.. do you tape the registration marks on the screen , so you don't print those in the garment?
I don't do screen printing, Iam an airbrush artist I paint electric guitars and bass. I cut paint masks on a vinyl plotter I have also used waterslide decals used them long ago on models before we could print are own lol. I seen this calca mikly white printing film 50 sheets 16
Bucks 8. 5 x 11 figured maybe I could use it as stand alone to transfer graphics to a painted guitar body. I've only had this stuff a day haven't tried it figured I'd do some research. So did bite off a bit more than I should. I know what screen printing is T shirts hats any thing that is crisp and multi layers and I know real quality model decals are done with silks screen printing. Other than that Iam a half ass guitar and bass player amature luthier. And well a l painter 😂
55 line tone, this is where i got lost. Where does this digit come from? I am an aficionado, amateur, and thrill seeker. I mostly do watercolour, oil, charcoal & ceramics.
This has answered some questions ive had! Like why does the image keep spraying out? Why did i start screen printing? 😂
Did you upload the final printed tee? Thanks for your videos.
I need help understanding which emulsion I should be buying. what is the difference between AP WP DC emulsion? also is I don't have a screen water dunker lol how many times do I like spray it with water on the squeegee side?
Hi Cam. Love your tutorials I have a question maybe crazy but what liquid do you don’t your screen‘s in after you burn them
If I'm watching this, it's because I'm not professional enough to afford such a devi e
Great video!! Would be willing to share a multiple color job. I would love to see how you burn / register for 2 + color jobs.
Awesome vid, keep grindin :D
How far underneath the screen should I have my light source (the one used to burn the screen) during the burning process?
how did you calculate 55 liner per inch on your design
Hey I will have some many problems to burn my screen , I have a lot of experience but now I used different exposure and my screens for some reason then washing put so easily.
You're doing a great job! Is that just water you're soaking the screen in immediately after burning it?
Why sometimes I wash out my details letter, the emulsion on detail letter can't hold /emulsion easily break on fine letter/detail?
What printer do you use or recommend to print film positives? Great video thanks
What part of Arizona? Do you offer screens for sale or know a good place?
More like you said, "I'm gonna kill the damn glass😂😂
what's in the pre soak tank?
Good ol fashioned water.
I made my 1st shirt tonight I think I'm in love
So, pre soaking is done after i burn the emulsion but before spray washing?
This is very helpful. Thanks for making this Print Life.
hi Cam, how long do you leave the screen out in the sun to post harden it?
I leave it out long enough for the water to completely evaporate. Usually 5, to 10 min is more than adequate in direct sunlight.
Appreciate that a lot.
what kind of exposure unit is this? I like how it has guides for the screen so it can be done perfectly . I want to purchase this type of exposure unit
good day sir how many minutes will you expose the film positive in UV LIGHT BULB???
20-30 seconds
How long do you put your screen in water to soak?
you can literly just dunk it quickly to wet the emulsion be we let it sit for 30-60 seconds
Happy new Year Cam and Print Fam. Not sure if you did something different with the audio but it sounds great. They say absence makes the heart grow fonder but F THAT welcome back LOL
Thank yo. it is different I'm using lav mics now. It's a pain in the ass to set up but worth the extra effort.
Bro what is inside the tub that you dip the screen after putting it inside the exposure unit
I love your the dont's cuz i used to have these issues, Pls do u hv a guide booklet one can download?
What is in your dip tank that you put the screen in prior to washing out.
Pls help me !! Idk why my screens suck
what are the little clear hard dots on my screen? it is creating pin holes in my screen.thanks to anyone who can help
Very cool!!!
xoxo The Clarences
I’m gonna clean the GOD DAMN GLASS
Hey man want to ask you that that colour you use for the scream print ?
So many questions.
What are they soaking in?
More great info Cam! Thank you looking forward to seeing more
why did the design come out backwards?
I keep washing my image out during the wash out stage
Me to... what the heck
Could be the exposure time not enough. All that depends of what kind of emulsion you use, i think.
Good stuff as always Cam! I gotta try soaking the screens, I think I wreck my emulsion sometimes.....especially on some smaller detail trying to blast it when its not ready LOL. …..did you get a new camera? That shit was looking all nice and crisp!!
Its a new lens with a speed booster so it's more cinematic, Im also using lapel mics now. I will dive in to as many tips as I can to prevent stencil break down, that seems to be a common problem.
@@ThePrintLife that would be awesome!! Looking forward to checking out and trying some new tips for sure.
It's like you read my mind....i woke up today to start my first print project and i am at the point where i am ready to burn screens.....i have a four color press, 156 screens and used four color separation to make my negatives. Am i on the right track? I have always been an airbrush artist, I've tried vinyl and now i am excited to get into screen printing. I don't have top notch equipment...built an exposure unit with a storage underneath that has a bathroom vent fan to remove humidity and a small space heater...also built my washout booth from a utility sink and corrugated plastic. do you have any advice to offer?
Nope you are going the same route I went start small make sure you like it then, start buying better equipment slowly, try not to go into debt early on.
Thanks that's good to know...i'm an artist by nature so being able to print my creations to garment i'm sure i'm gonna fall in love with it....minus the trials and tribulations. Looks like it all worked out pretty well for you. You do an awesome job explaining the processes....keep doing what you're doing. Whether you know or not it certainly helps encourage a beginner to take the leap and gives the confidence to be able to pull it off knowing that you are getting advice from someone experienced. I'm in a city where there is really no direct competition and i have a big client base from the airbrushing I've done over the years. I like that you are real people and act like some of the people i hang with.....not some company rep moving and sounding automated and scripted....keep up the excellent work my guy...looking forward to more videos.
Loving that squeegee action bros! I learned to print this way, but I regressed to stencils for home printing. Equally as good results. Thanks for your info.
Are you still using the uv floodlight until now?
Thanks
so cam you never mentioned about how many coats you put on those screens just wondering with half tones do you coat the screen 1-1 ?
1x1 fo sho
What is the vacuum string used for?
I've gotten consumed with your videos for the last 2 hours. Great information and entertaining. Good stuff brutha!
Oh man that is awsome to hear, thank you for watching and commenting you are the best.
Does the brand of emulsion make a difference or is it in the technique??
I can I have had some bad experiance with certain brands try vpr by chemical consultants.
Why is all my emulsion spraying out when I go to spray my image?
It means your emulsion isn't getting enough light to harden(cure). Try a longer exposure time. Good luck!
Guess I won’t be doing this at home
As someone new to screen printing... your videos are AMAZING!!! You've helped me more than I could tell you. But where did you get that exposure unit jig or did you just DIY it? Thank you for all the great videos!
this man blinging today haha like it
What colors does it take to print brass
Appreciate you so much !!
Bro what kind of printers are used to develop those films
Mine is an Epson 4800 oldy but goodie.
Clean the god damn glass people
Hey Cam, I am using a 110 mesh screen and I have the 50 Watt LED lamp you have. How long do you suggest I burn for? I have no had good luck, so I was wondering what the ball park time would be? Your vids are so helpful, thank you!
He said his was about 3 ft away and about 10 seconds, but 5 seconds for half tones.
How do you know your lines per inch?
I would like to know which emulsion are you using for halftones
Cci vpr

What film do you use?

What is in the pre soak booth?
What part of Arizona
How to print on accetate
Exposure times??
Useful thanks
Strange question, I know Phoenix area has pretty hard water, have you ever noticed anything with the quality of water causing mineral deposits in the emulsion when you're soaking them or even washing out?
funny you should bring that up, Yes we deal with it all the time. That is why we resorted to using compressed air to dry the screens.
@@ThePrintLife Good to know! I lived in Glendale/Goodyear area for 8 years and remember that water destroying my shower heads and leaving spots on cars like no other.
i dont like snakes
Welcome back cam! Love all you videos and glad to see your back making them! #Printfam
Thank you Adam. Im excited to be working on them again.
@@ThePrintLife I have started my own brand with a buddy and screen printing and your videos hands down have helped me to get started in this Industry.
I'm just starting my new adventure. I have a 4 station Hopkins press. I made an exposure box with 8 bright led lights. I'm looking at a Tecktongdh 2400 cabin fiber 110v flash dryer. Is the dryer Ok? How many PSI pressure washer should i get?
whats the best way to get films printed? i'm in a college dorm so i literally use copy paper with oil spread over to expose screens lol
trevor loucks I have been using this method for years ...
I bought an Epson WF-7720. Ink Jet transparencies can be bought on only less than $100 for 100 of them. Printer settings set to print on Photo Matte Paper.
@@imprintprintingco.9250 I used a WF - 7720 but get quite cracked ink and get some unprinted lines in it, do you think that’s because of the film I’m using ?
