  • Jake Oloya Dec 26, 2010
    i've heard that the image printout(image on a paper) can be use to transfer the image into the silkscreen.. is it true? how?
  • Jake Oloya Dec 26, 2010
    is there another way of transfering the image without using the positive film?

    I read somewhere that you can add sensitizer or ammonium dichlorate to ordinary PVA glue & it turns it light-sensitive. Does anyone know about this?

    Good info, but this technique is not really adequate, I stronhly recommend not to waste your money on photo emulsion, and get the professionals to do your frame for you.

    Cherry, there are a few things that could have gone wrong. 1. Did you remember to block off the back side of the screen so that light did not harden the emulsion form the back side. 2. You may simply not be using enough water pressure 3. Did you store your coated screen in a dark room, if it was stored after coating in a room with light it will harden. 4. your transparency was not tight against the screen and light go behind it. 5. your transparency was not dark enough and light could past through it. Being that you only exposed it for 5 minutes, I would guess that you may have inadvertantly pre-exposed the screen

    i exposed it for about 5 minutes on a clear, very sunny day, hosed it down, etc. when i squeegeed fabric ink over the image, nothing showed up on the t-shirt! anybody have an idea of what i might have done wrong?

    thank you for the method because sometimes i can't perfect it, so i always trying it in trial & error method.

    20 minutes?!? Sure I live in Florida, but I use Speedball Emulsion/Diazo and only expose for 60 seconds on a sunny day. And definitely print two transparencies and tape them together for a crisp dark image. A not-so-dark image and overexposure will make you lose any smaller lines and details in your image.

    I would try SpeedBall's Photo Emulsion you need the Emulsion and the Diazo mix. It's very easy to do and make and it last a long time and is cheap. This stuff, as mentioned dries like crazy glue and once dry is a real pain to remove from things like clothes and lids. Simple printers rule: Keep Your Workspace EXTREMELY Clean. Everything hasa place and everything is in order.
