How to Build a Low Cost Exposure Unit
This is a short video on how to build an exposure unit for silkscreening on t-shirts.
Video Rating: 4 / 5
Screen Printing exposure unit made using a guitar stand. The 500w halogen lamp is on an arm which is clamped to the stand, so it can still be used as a guitar stand when not exposing screens. I hope this might save beginners some money, as most of the 500 W halogen units sold in the UK are rip offs.

Every thing with this video is good except? the type of emulsion is not given. I am a newby and at this point I’ve tried 3min and 15 min one was to hard and one was to soft. Going for 7min and will see what that do. OH! I’m using wsb highbrid emulsion 500 watts halogen 15″ for 7min don’t know if it will work will see.
September 21st, 2012 at 1:48 pmdo i need? to have green film?
September 21st, 2012 at 2:21 pmvery big of you to apologize…I am sure Charese appreciates that.?
September 21st, 2012 at 2:45 pmhi, thankyou for the video, its exactly the information I’ve been looking for! will this work with a 400? watt lamp?
September 21st, 2012 at 3:26 pmAww man, I’m sorry for acting like a total D!(K. There’s NOTHING wrong with this setup. I’M? SORRY CHARESE, YOU DID’NT DESERVE THAT. IDK what my problem was that day but my friends all say I get a menstrual cycle more than once a month. I had one that day. FORGIVE ME PLEASE.
September 21st, 2012 at 3:27 pmThe glass presses the film positive next? to the glass, acting like the vacuum would in a professional unit.
September 21st, 2012 at 4:25 pmAspiring printers and? upstarters: Pay attention! This thing works really well.
September 21st, 2012 at 5:22 pmThanks for this video!!!!
ROFLOL so u are one who thinks that he needs to spend thousands of dollars on expensive un necessary toys just so u can impress ur clients? LOL go for it man! go into debt! buy all that expensive junk so u can? make payments to the man the rest of ur life or until ur business collapses because u arent making enough money to cover ur payments and feed urself too.
I prefer the CHEAP that WORKS ways like these. My business was paid for with my first 6 jobs! 😀
thanks Charese! 🙂
September 21st, 2012 at 5:59 pmI use your system at it works better then my two commercially bought exposure units.
Also, do you have any plans in the future for a DIY Hat Platen? Only? say two on youTube.
Thanks for your videos.
September 21st, 2012 at 6:13 pmwhat? emulsion are you using?
also you could make this into a height adjustable set up using brackets like they use in stores to hold shelves up just fix 2 strips onto the wall for either the light to move or the board or both
September 21st, 2012 at 6:46 pmWhat is the purpose of the glass? Is it? necessary?
September 21st, 2012 at 7:02 pmThe reason you would need to use more than one light is in order to ensure that the light is hitting the design at a 90 degree angle. You can play around with this if you like? but the majority of designs intended for plastisol inks are not fine enough (including half-tones) to require such measures.
September 21st, 2012 at 7:46 pmthis was verry helpful thank u so? much! she has awsome boobs aswell 😀
September 21st, 2012 at 8:40 pmMost cases of printing on textiles today utilize plastisol inks which are very thick. Because of this the screens used are coarse. So one lamp, 12 inches above the screen will be sufficient. ? Even in cases where 320 mesh screens are used. You can raise the lamp if you wish to cover a? bigger area (it’s the size of the design that is important, not the size of the screen). Of course, you may have to lengthen the exposure time a bit.
September 21st, 2012 at 8:43 pmwould you need more than 1 lamp if you were doing? 23″x31″ screens?
September 21st, 2012 at 9:40 pmThis process works wonderfully especially when calculating exposure time. You go ahead and spend your money to show off but this same system is working fine for me doing simulated process printing at 50 dpi down to 20%? opacity on 320 tpi screens. The ultimate exposure point light is the sun and those overpriced units are really not much better than a $20 quarts lamp set-up like seen in this video. This saved money is much better spent on a quality press.
September 21st, 2012 at 10:31 pmSunlight is good But Wat If U Work At Night… Or Live? In Seattle… Come On Dave Be Nice ..This Is One Of the Best Videos On This Topic
September 21st, 2012 at 11:07 pmHi, have you heard of this thing called the Intellitus Cash System? (google it). My father says it gets people plenty? of cold hard cash.
September 22nd, 2012 at 12:02 amSunlight is all well and good if the sun is out or indeed if you are doing this in sunlight hours or it’s? not raining, hailing or snowing and it’s not too windy. Ahhh, think I would go for the lamp for convenience.
September 22nd, 2012 at 12:18 amWhy can’t sunlight be used, instead? Zero cost, and i’ll bet it sets the emulsion at least as well as a lamp. I’m just curious, since sunlight is still? free.
September 22nd, 2012 at 1:17 amyou are right noob here! if i get customer with this amount of money then? I will be able to afford proper stuff. But this is great for beginners and hobby users. Also my customers dont give a shit where i ma producing t-shirts. they only interested with end product.
September 22nd, 2012 at 2:14 amIf you have a customer with? thousands of orders it’s obviously time for an upgrate. This video isn’t for a huge pro setup, it’s for people who want to build at home. Don’t be such an asshole.
September 22nd, 2012 at 2:49 amwhat size glass do you use?
September 22nd, 2012 at 3:15 amAwesome, thanks man! I? just built my own 4-color press last year and I’m trying to figure out the best DIY ways to do this stuff. Speaking of which, do you know any good DIY methods for flashing the ink?
September 22nd, 2012 at 4:11 amthanks for the reply. great would like to see ur new press…but also like? to see ur old one and hear what problems u found 🙂
September 22nd, 2012 at 4:21 amThanks?
September 22nd, 2012 at 4:53 amI’ve done upto A3, i’m guessing you could expose an A2 sized image aswell. None of my screens are big enough for an A2 image, so i can’t put? it to the test.
September 22nd, 2012 at 5:47 amAfter using the press a couple of times, i found a? few problems with it, so i removed the video. I’l put a video of my new press up soon. Sorry about the late reply.
September 22nd, 2012 at 6:34 amSO sick, im doing this! can you expose a2?? whats the max size of exposing do you think?
September 22nd, 2012 at 7:25 amwhere’s? the video of your 1 color press?…after watching this i was wanting to see it but could not find it. thanks
September 22nd, 2012 at 7:33 amyes if you leave the light on too long the? emulsion will over expose and the image will not wash out where it is supposed to.
September 22nd, 2012 at 8:06 amis there? such a thing as over exposing? like leaving light on it for to long?
September 22nd, 2012 at 8:34 amThis video is awesome. Can you? put your one color press back up PLEASSSSEEEE!?!?!
September 22nd, 2012 at 9:02 ampretty? slick
September 22nd, 2012 at 10:00 amThanks for the comment, yep a 300w light should work. Just try an exposure test to get the right time for your light.
September 22nd, 2012 at 10:36 amI’m no expert but i’d guess a 300W light would take around 20? min to expose a screen. Good luck.
I set the light roughly 22? inches from the base and get decent results with a 13 minute exposure time.
September 22nd, 2012 at 11:03 amvery nice! whats the? distance between the bulb and the base and how longs your exposure time?
