This vid was super helpful! FYI for others, I used 8 lights, 3.5 inches apart, 1/4" glass/screen about 5 inches away. I used murakami photocure pro diazo on both sides of yellow 230 mesh screens and got a perfect burn at 3 minutes. I'm going to also try photopolymer murakami blu next week just to weigh my options and test emulsions.
This travel vacuum bag technique is genius!! Good stuff!!
Using a vacuum space bag for holding film positives against the screen is genius! I was stressing over finding a piece of glass of the right size. This is cheap and effective. Thanks for sharing this knowledge!
I stressed about looking for a piece of glass for a long time too
@@StartScreenPrintingNowTV Your videos have been really helpful. Hope all's well!
Nice to see you back (y)
I followed your instructions and it works great :) Definitely worth the ~$40 on amazon
If anyones interested Pro Chem Dual cure emulsion from Anthem Screen Printing works with these lights. My setup is, Lights are 4 inches from screen with the lights being 1 inch and a half apart from each other across the whole 20 by 24 screen length wise. Exposure took about 5:30 minutes. Comes out with a fan spray water hose easy enough, however comes out easy with 1600 psi pressure washer. I use a ryobi 1600 psi. hope this helps.I stand about 24 inches away when pressure washing.
Man thank you for your videos and your tips. I am gonna try this cause I dont habe too muc space at home and this is the best idea I have ever seen.
You are very welcome! Happy to help
Hey!! Glad to see you back! You are so dang smart and creative. Awesome Job!
Thanks tshirtchick! You have an awesome channel too!
Thank You!
@@TshirtChick I love both Channels!!! I've learned so much so both of yous!
First off thank you for the information. I built my unit with 1/2 particle board at 16" high by 20" x 24" and mounted the glass on 1" x 1" aluminum angle pieces at 1" below the top. 4 lights as suggested. I went with the high number for exposure at 3 minutes which was way too long. Using AP blue I did my second test at 45 seconds and it was perfect. Just a heads up build your box about 2" longer as the Daisy chain takes a little more room than the 24". Overall a great build and what a time saver, thanks again for the video.
Glad it helped! Sounds like you made a way better one!
@@StartScreenPrintingNowTV I was just following your lead 👍
I appreciate the exposure you bring.
Awesome video. And using the cacume bags is genius
Thanks again for Anotha one... Really enjoyed watching all your tutorial videos, I think I watched all of them 3 times.
Thanks Gus! I'm glad you enjoy them!
@@StartScreenPrintingNowTV Will you be making a video on pricing to customers?
That is something I'd like to do but my wife is more in the pricing and selling side of that. So I'll probably pick her brain and see what pricing she uses.
I think I'm just going to use this method. You've got pretty much everything covered here, it seems. If you care to share how it's worked over time that would be much appreciated!
I was just thinking of doing this idea with those stick on light and a cardboard box with lid.🤞this makes me a little confident to try it. Hope the light is not too strong on photo paper.
I’m going to build an exposure unit using these lights very soon!
I cannot wait to try this!
Thank you very much for this really helpful video filled of information!🔥
as always very useful information
and like you say screen printing does not have to be expensive
U helped me a lot bro !! i hope u find time for more videos
Built this to your specs with the same lights. I used ecotex pwr emulsion. I did an exposure calculator. I got 2:06 for best time. And a few minutes later the image started disappearing. I then increased my time to 6:30, still image disappeared. Ecotex stated none of their emulsions should be used with black light. So I’ve sent back the lights and will try a 500w work lamp.
I did the same. I got ecotex LED emulsion though. I am testing it this weekend.
@@larryfenix how did it go?
@@DonalRomano It took 12 tries but I finally got it. I got it to burn the tiniest halftones as well. My setup is about 8 inches below the glass. I had a super difficult time getting certain areas to expose right. I went through 11 screens doing this. Then I decided to try the vacuum bag because I felt like light was getting in between the transparency and the screen. 38 second exposure, 10 seconds with the pressure washer, and it was perfect.
How do you not show the final results in this video? 🤔
Thank you for this video, I habe the 2w 6 lamps wich are smaller than your lights!!! IDK if they work or simply put more secs !!!
so glad I saw this video I was about to spend a bunch of money im building it now ! thanks
But will it do halftones ?
I bought the LED's. What kind of emulsion are you using to get 45 second cure? Does it hold up halftones very well?
I'm just using cheap Jacquard emulsion now. Works good for me.
does the vacuum trick actually work
It does! But if you get a cheap vacuum bag like I did, it leaks pretty fast but still holds long enough to burn a screen
Does this set up burn halftones?
I should be able to use my old fluorescent black light tubes , what do you think? I believe they are more if then led's. I'm new to photoresist but I have some old black lights lying around.
Your input would be greatly appreciated.
Thank you
Is black light also UV light? Does this work with waterbed emulsion?
Does this help to burn halftone image? Or which light do you suggest for halftone screen burning?
Will black light uv bulb work
Witch is 18 watt
What time are required to burn 200 mesh screen with thise bulbs
Have you burned any screens with your new black light setup? I was just curious if they produced enough illumination to cure the emulsion? Also, I know that you mentioned the name of the emulsion that you used and was curious if it is specific emulsion for black lights or will any type of emulsion work?
Thanks for another awesome, money saving video!!
Yes I have burned 3 screens with it and works great. The emulsion in using is not specific to blacklights. I got it off of Amazon for about $8 a jar
Jo casey whats good? Question. Does the lights have to be that high or can you do it lower ( so closer to the screen) with a shorter time period? Hope to hear from you. Tris
Hey, just discovered your channel! Thanks for posting your DIY build! Quick question, are there some results you can show from this setup? I'm looking into doing stark black and white photo screen prints, so there are small details that will need to show up. Will a set up like this work? Any thoughts? Thanks again!
Working on the same thing have you tried it with the lights closer? I want to have this built into my work area maybe 6”/8” from exposure glass. Nice job and great project. Thanks for sharing!
Was thinking of making a little platform to move the screens closer but haven't decided yet. Thank you!
What screenprinting press is that in on that little table nice video
That is an older Ryonet Silver Press I got used from Facebook marketplace. I got a really good deal on it! 4 colors 1 station.
@@StartScreenPrintingNowTV
Almost three week ago I see the same Printer Press and was for sale $300... It is good price?
I took your recommendation on the printer.... Thank you for the advice. Have you had any issues with light coming thru when exposing?
I have not. I print directly from Photoshop using high quality print setting and seeing the media type to photo paper matte. I'm recording a follow-up to that video to answer some questions and to go over the print settings a little better. Thanks Gus
Hi where do I find the description would like to know what kind of lights to buy, based in the UK (not sure whether that makes a difference) I find trying to work out what bulbs to use is a mine field 🤷🏻♀️👍🏻
Got it 🙄👍🏻
Do u keep the vacuum on while u expose
I do yes
Is this light effect to human, and can dry the ink?
we need a DIY flash dryer....
That would be hard without burning the house down!
Just use a heat gun
@@MrCODCLANBATTLE Im using a heat gun, but when your doing like 60 to 80 shirts a heat gun no good. I NOW have a flash dryer, and am buying a conveyor dryer
Hammer USN yea that’s true it would be hella slow
how long does the burning take with these lights???
About 45 seconds to a minute
Wow!!
Has anyone ever told you that you look like channing tatum?
Yes. I've heard Josh Hartnett, Emeryl Legaci, and Robin Williams as well.
