    Hey Josh! Another great video! Did you take the glass off your UV light? I have one of those too in my DIY set up and my time is about 14 minutes...hoping that would cut down my time.

    • @joshisterrific
      @joshisterrific  Před 3 lety +1

      No, I'm using the light as it came. That may cut it down a little, but if it's the same light I would assume the difference might be from the type of emulsion, or maybe the distance between light and glass?

      @@joshisterrific Okay, thank you for letting me know! I'm using the DIY method you mentioned in your video with the two legs and overhead arm. I'm about 13 inches away. I'm wondering if I should put a box over it to encase in the light. Thanks for the input--great job on the videos!

      @@heatherjennings145 hmmm, I think mine is a little closer to the light. Either that, or the light isn't as bright. Could also be the type of glass. I tried to get the clearest glass I could find. You could try the box idea, but I feel it should still be lower than 14 mins even without that. You could also try adding more UV light to the mix to make it brighter.

    Awesome! Thanks for the vid. Question, if my screen was under or over exposed do I need to reclaim the screen or can I just re add emulsion let it dry then back to the exposure unit?

    • @joshisterrific
      @joshisterrific  Před 2 lety

      You should reclaim the screen and start again. I wouldn't keep the old emulsion on there.

    Underbase film what u mean? Why it shout me with more down mesh?

    • @joshisterrific
      @joshisterrific  Před 10 měsíci +1

      An underbase is a layer of white underneath the other colors in your design. Not everyone uses one, but it can help make the top colors brighter/more vibrant on dark colored garments. If you use an underbase then its typically done with a lower mesh than the top colors.

      @LLLLLLL156 I would use a fash dryer in between colors, let it dry for about 10 seconds before moving to the next color. The exposure unit has 140 watts with the UV lights I used, a link to those should be in the description of that video.

    • @joshisterrific
      @joshisterrific  Před 3 lety +1

      @@TheDIYWarrior my first guess is it's underexposed and that it needs a little more time with the light. I also have been told that a pre-soak and washing out the back side first helps with this. As for air bubbles - I've gotten some of those, and I try letting it settle naturally in the scoop coater or shake/tap it if I need to, but sometimes I just can't get them all and I try to just make sure the coat is as consistent as I can get it. I like the Ecotex emulsion okay, but I'm still trying out other kinds to find one I love.

      @@joshisterrific Thanks for the advise. I'll definitely step up the exposure time (right now I'm at 1min). I'll try a minute and a half or so.
