Bob you're a champion of common logic most videos are so long and go in circles you made a 2 minute video that explains it perfectly I salute you I just happened to find this lol subbed refreshing to see such a simple and solid tutorial
I had been "broken my head" thinking how to get an exposure unit or building one but now I see that I can have one without spending more than 30 dollars. Thank you
My first burn worked like a charm. Thanks! I went five minutes with a double-element halogen shop light with the glass removed (it said "UV Filter"), about 16 inches away from the 110-mesh screen. Next to try: the 305-mesh screen.
+Jonathan Prizant Make sure you get the timing right, and then don't change anything. for example, make sure the light is the same distance away from the screen. I'm pretty happy with four minutes and ten seconds with my setup. I use Chromaline brand Chroma/Tech PL emulsion.
Sir, thanks for the video. Your description of the light source was so clear. Could you please describe the difference between this and a professional unit with regard to the light source.
I guess you can but it'll take much longer to expose. Think about, it's not about the light intensity you have, it's all about the amount of UV light your light emits.
Using very same kit although top down method I place glass over the acetate sheet to weight it down expose for up 18 minutes using 500w halogen light and it still isn’t working screen just washes straight out no trace of image having transferred atall, light is about 16 inches above screen .... any ideas ?
i built ine just like yours but have had sooo many issues. do i need to cover the sides with a back blanket or something? i feel like too much light is getting in. when i wash them out either the images bubbles and falls off or i cant get all of the emulsion out
I think before you investing in uv bulb. You should get around sun light. Cuz it's way more faster than the exposer unit. An osram Mercury bulb 250 watts takes around 7 to 10 mintues whereas the same thing in sun light can be obtained in merely 5-7 seconds.
@@thakurboys5962 true but sun is incredibly inconsistent, especially in places such as the UK (where I'm from). I started printing during the summer and now that it's getting to autumn/winter i thought it would be time to make a place to expose my screens inside
@@валентин-с3р yeah this is sure the thing one should opt for if winter or rainy season around. I too use HID light for exposing when Sun is not around. Edit: Looking forward for investing in UV exposure unit. But I will make it as a DIY project.
@@thakurboys5962 that sounds awesome i hope to do the same at some point in the future, I'm making the same setup as the guy in the video but using a 230 watt halogen floodlight, do you recommend just doubling said time in the video?
Wondering what i could get away w using. Instead of a scoopcoater ? Could i get away w using my speedball squeegee and scraping excess off w my Safeway savers card? Lol

Thanks a bunch... I have a table with an open metal frame... May try to add glass and use that!! Soooo excited!!

Is the 16" measured from the actual bulb or the top of the lamp?
Nice honest assessment of a homemade unit
Thank you! awesome tip. I really like the concept from the bottom up - it makes it easy to get the positive contact from the image to the screen.
Great SHow👍
Sir, thanks for the video. Your description of the light source was so clear.

How would an LED bright light work?
what emulsion did you use?
What if I can't find a glass
hi!, can i use a plexiglass and 30w LED floodlight?
I guess you can but it'll take much longer to expose. Think about, it's not about the light
intensity you have, it's all about the amount of UV light your light emits.
how thick is the glass to be used?

are you sure you mixed in your activator?
What is the watts of your exposure light Sir please put on the info so that we can build our own too and what is the exposure time.
most likely 400-500watts
how many price the Light box?
i built ine just like yours but have had sooo many issues. do i need to cover the sides with a back blanket or something? i feel like too much light is getting in. when i wash them out either the images bubbles and falls off or i cant get all of the emulsion out
Can use any bulb? Or only uv light?
UV is better

Halogen emits UV 350nm to 450nm ?
thanks give me easy solution
you got to be kidding me, you not going to show the end?
...that would have been nice to see the result...
thank you :)

Sir tell me exposing timing please.
12 sec
nice
a like it really
Молодец
I have this light, what will it do with it? (500w Halogen Outdoor Security Light)
