- The moment has finally arrive where I test a very Affordable 50W UV LED Flood Light to use on my future Homemade Exposure Unit. Everyone knows that UV light is the best option to expose screens as it is the fastest to do so. Here, after browsing many Options, I came to this LED light that is really cheap but very good quality. This was just a few quick test I did to see how it works. I still need to perfect it. But this is definitely a BUILD UP to my shop. Hope you enjoy. Thanks again to the people who had helped me to make this possible.

So glad I have this light in my shop. Will be a big help when exposing screens. What are your thoughts?
Way better. Menos perdida de tiempo siempre es mejor. Saludos
@@MrIonathanmtz Exacto Amigo. Saves time when exposing multiple screens. No más esperando. Jaja.
@@TheInkBuildUp oh for sure! I think I'ma get myself one of those uv lights now
@@MrIonathanmtz Awesome 👍
Better, since it will save time 😊
The best part of your videos is that you pull off clean prints with relatively low tech items in your shop. You see people on print forums insisting we have to have the best screens with perfect tension, a vacuum exposure unit, a high pressure power washer, pre-registration table and here you are holding an exposure light with no specific height from the screen, blasting out the stencil in the sunlight using a spray bottle. it's awesome to see and really makes me think that I am often overthinking things when trying to troubleshoot. Keep putting out videos. they're inspirational
I totally understand what you mean. That's how I was when I first got here and realized how they did it here. Always thought I needed all the best equipment but not necessarily true, but if you do have the best equipment, it will make things easier.
Thank you for your time and the advice on the light - I'm getting into screenprinting and I think your content is great! Cheers from the UK!
Glad you enjoyed the video Amigo.
Good job keep striving
Your screens stay perfect!!
Thanks for the video man. Its been super helpful! And thanks for some of the comments below.
Thanks for watching, and glad it was helpful Amigo.
Excellent demo. Now I'm confident to buy one of these lamps as I'm just getting into printing and so many suppliers promote their own stuff which is often over complicated or they are vague about the detail. Greetings from Scotland and thanks for the info
thanks Amigo, glad the video was helpful.
Love this Antonio !!!
Thank you Amigo
I learn a lot this man. More power
Glad my videos help.
Your such a badass man keep up the hard work bro. The Mexico life is real I share your videos good luck my friend
Thanks man. I really appreciate it. 🤙🤙
Think I’ll try that light
Thanks man I tried your method it worked like magic, have been struggling to burn my screens cos I'm a beginner ✨❤️
You are inspiring bruh. Love from India bruh❤️
Thank you for your video
Thank You for watching.
Great job!! Thanks so much. I am just starting to screen print...not sure about why/when after placing the emulsion onto the screen, where to keep in dark place until using LED light or not, etc. Guess trial and error to see. Thank u for this video!!
No problem, and yes, you'll go through a lot of trial and errros into you get it right. Patience is key in screen printing. And you can just leave it in any dark room. A yellow light safe room is not exactly necessary, it helps but not a must when starting out. I just leave them in my shop with the lights of until it dries, than sometimes I put them in a box or just place a dark clothe over them.
IM YOURE BIG FAN NOW,,from philippines
Awesome, glad you enjoy the channel.
Teşekkürler dostum harika çalışma :))
çok teşekkür ederim
spray bottle to save water i love it. keep buiding ink up. im mexico sure is a great market, no many people do that.
Yes it does save water but just a little time consuming. And true that many people do screen printing here in Mexico.
Thnks for sharing us your knowledge.....
Greeting from India buddy 👍
God bless you
Always glad to share.
@@TheInkBuildUp how many years do you have experience in screen printing?
@@shivamrai5749 2 years Amigo.

After watching your video i bought the 30 w black light so hoping to test it with 60 secs ...thanks for all the info bro
That's awesome man. Glad you made the decision to go with UV light. best option, and the times also depend on the emulsion you use. Hope you get good results Amigo.
wow thanks for testing this I think I'm going this route I have been using a big heavy yard light with a halogen bulb that was homemade been using it for forever! but I think I'm going to give the 100 watt version of the light a try and see if my can get my time down to 30 seconds my current exposure time is 1:30 but getting it down to 30 seconds or less would make my jobs faster for sure all my jobs are multi colored , what emulsion were you using? the green makes me think it is chroma blue? I also like the fact it turns on and of right away, The light source Imp using takes a min or two to warm up, and if it shuts off when hot it will not restart until it cools off...
thànk you Bro nice educational video.
Glad you enjoyed it and thanks for watching.
Awesome carnal
Thank You
@@TheInkBuildUp le voy a entrar al rollo del Silk screening. Solo para uso personal. Haber como me va. Muchas gracias por subir tu contenido. Suerte!!!
Sometimes I ask myself questions; Why is it that every screen printer one time or the other is never satisfied with his job? For me I have also purchased a 200 watts flood led outdoor lights for my screen jobs whilst I still have a 6 long fluorescent day lamp bulbs exposure unit that I expose screens for 10 minutes. But I still want to lessen the time to seconds or at least a minute. It is still part of us, build it up.
bro i like and enjoy watching your videos. i also screen print from my garage. i have the equipment except the exposure unit. have been thinking about buying the same light the "Quans 50W LED Flood light" the one Print Life is using. now i will buy it bro. you are motivating me to stop being lazy. with the low tech and small equipment you make it work and you do better and alot my brother. i admire you and envy your passion. keep the videos coming and ill always watch.
Thanks for watching, I appreciate the comment. And yes, definitely buy it. These UV lights are amazing, I hesitated at first but had to try it. Worth every cent. 👍👍
Thanks my brother im on amazon rut now looking for a timer thats easy to setup and run i built my own exposure unit and im using 1000w halogen and UDC 2 chromaline emulsion and im getting 10-13 minutes wanna cut it down and start experimenting on cmyk and halftones. Whats your facebook page? Mine is “SOS Screen Printers” ill appreciate a like 🤙🏽
@@King_stunnar awesome. Well I actually bought a timer, but I'm going to try to wire it up today to see how it works. And my personal FB is "Sewer Oner" and also have The Ink Build Up FB page. 👍👍
Please do a video on how u set it up and how it works...
@@King_stunnar I will definitely do. 👍
Get your self a HAND PUMP TO WASH OUT EMULSION AFTER EXPOSED.. LIKE used to spray fertilizer or inspect weed killer garden shop ...like $15.00--$40.00
Spray faster and more PRESSURE or less PRESSURE but wide spray easy pump by hand 7 pumps done
Yes, that's something I've been wanting to buy since the beginning. Haven't had the chance to do so.
On future videos can you add the distance from the light to the screen as well as the type of emulsion you are using. Great video 😊
Will do my best to make more content going back to these questions.
just a thought... see if you can get a hold of a pump sprayer (the kind you spray for insects) it will hold more water and give you a faster spray out.
Great idea. Will look into it.
What I noticed in other videos when exposing a screen is having none UV lighting when coating or exposing a screen, having a “dark room” with the UV free setting would have avoided the wash-off spots
You are the best, liked the video.
I have a Union BLB F18 T8 black tube bulb, is that also a good substitute for burning screens?
Thanks Amigo. And I can't really say since I have no knowledge of that light.
hi ink build up great video what is the frame you clamping over the screen is it a glass frame with a hinge could you show that set up thanks steve
Hello Amigo, yes it's glass with a hinge. But no problem, I'll make a video where Ill show it more detail.
yeah! clicked "like" just for that rooster singing.
Real hustlers are working before the rooster sings.
Hola que distancia le pones la luz y cuantos minutos , Gracias
Hey! I just bumped on your Channel and I appreciate your sharing of knowledge.
I’m trying to build my own exposure unit so I have a few questions.
I’m hoping you can give me some feedback.
What’s the correct distance from light to frame ? I’ve been reading on your comments and some say that 4 feet and other 12 inches. That’s a lot of range distance. What are your thoughts?
Does it matter if the Uv light is 60W? I haven’t found a amazon supplier that is shipping a 50 W Uv light to México currently.
I Appreciate your work man!
Glad to hear my videos help out.
As for the distance, it depends on your light source. For example, on a flood light like mine, you have to have a certain distance that will spread out the light evenly. I have mine at 12 inches which is perfect. And a 60w will work fine. The one I bought was actually delivered to me here in Mexico but yea, I check and they longer ship to Mexico. But you can try and search cause they're a few others that do ship here in Mexico. I'm currently going to build a newer exposure unit, but this time I'm going to use UV LED strips.
You would be able to get much better prints if you put the light below the screen and added a glass and some pressure. The light is way to close to the screen. I can get a 15 sec exposure on very detailed prints .
Good first try, just needs to work out a few kinks
Thanks. And yes, I'll be making a new exposure unit where I would place the light on the bottom. And I do have a glass pressing the film to the screen but doesn't quite have even pressure so another reason I want to make a new table. And hopefully yes, when I make a new one, that I can lower my time a bit.
Thanks! Are you using a Dual Cure Emulsion or a Polymer? Thanks for the help... much appreciated!
You can say it's a dual emulsion since I have to mix the Emulsion with a chemical called Bicromato to activate the Emulsion.
@@TheInkBuildUp thanks for the quick reply. I'm getting ready to place an order but really wanted to know what to get for this particular light.
@@BillyDiamond No problem. And since you're barely starting, i do recommend a dual cure since polymer emulsion already comes light sensitive and you have to already know how to work with it.
@@BillyDiamond hope this video will help if you haven't seen it.

I just picked up two 30 watt ones. My friend was getting 30 seconds with two 30s
30 seconds. Wow, that's awesome Amigo.
@@TheInkBuildUp amen hope my results are good too after watching your video.
@@sdhute Yea man. Whatever time you get, its better than using a white light.
Dude that’s insane what do you use to get your halftimes is there a way I can reach you and talk? It would be awesome to get some tips !
Well right now I just took a guess to get my times. But there is this exposure calculator to get a better estimated time, I just forgot about it. And well, you can always message me through Facebook or Instagram.👍👍
The Ink Build Up haha I wrote half times but meant to say half tones! Good work
@@germisrich137 oh. Lol. Well I use Photoshop to get my halftones.
Any ideas on how long it took with the 30w you have?
If you're talking about my White Flood light, that one takes 10+ minutes to expose my screens.
I've been having issues with half tones and exposing properly. It takes a long time to expose ANYTHING with a 30 watt uv light I bought. Should I go higher? To 100 watt? Your half tones came out really well here with 50.
I believe that a 50-60w should be fine. A 100w I think is to much.
@@TheInkBuildUp I've seen other people have 250 watt exposure units. So I think it should be okay. I just don't know why 30 watt is making me wait like 20 minutes
@@deathprocess 20 minutes is a lot. And your Emulsion also can be a factor of the time it's takes to expose.
@@TheInkBuildUp so I figured out that it was my glass I was using. The glass I put on top of my screen was blocking all the uv light. I removed it and it brought it down to 5 minutes
@@deathprocess WOW big difference. I have heard that some glass does affect the time. Good thing you solved your issue.
Respect the fucking hustle! 🙏🏽
Thank You Amigo. Sorry for the late replied.
What model is the UV light lamp? My study indicates to use dark room to apply emultion but my instructor alleged it is not really necessary, his colleague did not use for 20 yrs he said. I made my own dark lamp based from a chart from Kodak. red light for X-ray, etc & so forth
Can't remember the model. And yes, working with emulsion should be in a yellow lit room. But I only see that necessary for storing and letting dry your screens. When I coat my screens, I do it in a lit room since it's still wet. And when finally exposing. I do it in a lit room as well, as long as you don't leave your screen there for a long time, you shouldn't worry to much. But now, I did add some yellow led lights to my shop, that way I don't have to worry about it and feel rush.
Hola! Amigo.., what should be the thickness of the glass which we put on the screen....
Can't really say, but mine is about 3-4mm.
Whered you get that spray bottle from lol i dont have indoor water source for a pressure washer so i need sometjing like that
. Here in mexico, they have this plastic stores where they sell everything with plastic, (cups, bowls, trash cans, taples, etc....) but you can find them at about at any major store. Have to look at the cleaning section.
@@TheInkBuildUp so i can take screens outside after exposing then wash them out and bring them back in? Because i would have to go to my house which is a mile away and use a water source there then go back to my office
If you're going to wash out the stencil outside, I recommend you do it in the shade and right away. You don't want to have the screen outside for too long before hitting it with water. I usually have a bucket of water next to me.
Interesante bacano . esas luces de construcción amarillas q se usa cuando no hay luz y calienta de lo fuerte q es .. también sirven para esto o no . no se si las conoces . esas LED son blancas verda
Hola Amigo. Y si se puede con esas luces amarillas pero a muchos, le dan como 10 minutes y el problema es que si calientan mucho. Te recomiendo los de LED. Y el que yo tengo es de Ultra Violeta, son mas rapido que de la luz blanca.
Gracias bacano . ahora mismo lo busco
What emulsion are you using in these tests?
I'm using Sanchez Emulsion.
will the 80 watt version work better?
Yes. Definitely. But For me the 50w takes a couple of minutes, but for others, less time. It all depends on your emulsion.
Hi please where did you get the squeeze bottle
I buy them locally at the market.
what is the best LED lamp? 50 watts color the blue light or white light ?
You want UV.
How long you dry the screen after coating emulsion.
before my dehumidifier i would let dry about 30-60 minutes just to be safe.
The Ink Build Up thanks for your reply.
@@Laptop_repair_zone No problem. Always glad to help.
Did you end up building a box for your exposure unit?
Sort of. I didn't build a box, I just turned an old table to my exposure unit.
Are you going to review it?
@@kimmiesrhythms I did a video where I test it.

what Emulsion were u using ? Thanks
Here I was using an Emulsion sold here in Mexico. It's not Diazo.
otra pregunta, cual papel usas para imprimir el positivo?
Aquí. Uso papel Albanene
@@TheInkBuildUp es Como el tracing paper? o de calco?
@@adrianabarrios5317 si, como el tracing paper.
@@TheInkBuildUp great! gracias
What emulsion are you using?!?!?
I was using an emulsion that they sell here in Mexico. It's an affordable brand. Not the best but still gets the job done.
Other printers have said that the 50 watts is too much.
Q papel utilizas tu camarada para tus positivos
Uso el papel Albanene te compro aquí, pero ahora uso film de goldup ya que tengo una impresora.
Gracias bacano
Amigo does Led light 50/100w (non UV) will do the job ?
Yes it will. Before this UV light, I used to expose with a 30w flood light. Took long but it did get the job done.
How long does it take you to expose with the 30w flood light ?
@@e34world well with the Emulsion I used here locally, it would take me 10 minutes. With this new UV light 1 minute with 40 seconds. It all depends on your Emulsion as Well.
Does it has much sense to buy 100w non UV led light instead of 50w non uv led?
And thanks a lot , Amigo, for the fast answer's
Hi I bought a 50w led flood light. Its not a UV though. Is it okay to use it for tshirt printing as well?
If its just a white flood light, yes you can still use to expose your screens, however it will taker longer to expose.
@@TheInkBuildUp Oh my gosh. Thanks for answering. Since it will take longer exposure time, how can I possibly know if it's already enough time for the exposure? I've been watching videos abt it and still haven't learn to calculate it.
@@rhomeainlayo431 No problem. And you can use the exposure calculator to help you out to try and figure out your time. Here's the link to the calculator and 2 videos where I had used it, so you can get an idea of it.

Why did you to get 50 Watt? You could have chosen a higher watt
Yes I know but I was on a budget. But i later learned that 50w is okay. Saw a post were someone got a 100w UV light but their time was too fast, like 4-6 seconds. Yes it's fast but too fast that it wouldn't give the emulsion enough time to expose probably. Especially on the halftones. They kept getting exposed. But I recently purchased a 60W UV LED strips.
Great keep going
Is there anything wrong with overexposing by a little bit? Why not just let it cook
If you let it overexposed. You'll have trouble washing out the emulsion from the screen. Especially if your films aren't that dark.

What experiences did you have after making this video and what was the best time you came to?
It's been awhile since I made a video, but this light helped out a lot more than compare to my old methods of exposing screens. And I can't remember exactly the time I came up with. But it was around2-3 minutes. As compare to a white flood light, that I was doing at 10 minutes. Big time saver.
Light source too near put at least 4feet u will get the best results
Thanks, I'll keep that in mind on my next test.
hi
Hello Amigo 🤙
take the glass off. it blocks some UV. I do 30 seconds with the 20W version of this light on ChromaBlue
Yea I heard, but I forgot about it when I was testing. Only remember after I was done. But next time, I will sure take off the glass.👍
