    Default vegetable oil questions

    I'm going to start printing using veggie oil and just had a couple of questions I figured people could help me with...

    how do I know when the exposure is complete? i'm assuming you can overexpose, so i want to avoid that.

    will exposure take longer since i'm not using emulsion?

    do i need to rinse the screen after exposure, before printing?

    thanks in advance to all.

    if you aren't using emulsion what are you gonna use? usually exposing a screen involves emulsion. you gonna use capilary fims?

    to my knowledge, and from my experience...

    the oil is only used to make an opaque piece of paper transparent. you still need to coat your screen with emulsion, then just use the wet, slippery, oily piece of paper as your transparent separation.

    does that make sense?

    you can get the oiled paper pretty dry by wiping it a couple times each side with kitchen roll. I set up two large sheets side by side, oil the positive on one, slide it to the second sheet and wipe off.
