But wouldnt taping something to the board not produce similar undesirable effects or at least end up with part of the board not being covered?
Also,
Something that really sets the commercial stuff apart from the diy, the black film that they stick to the sprayed boards, to prevent unwanted exposure.
It allows you to work with the board before you expose it. i.e cutting etc, thus making it possible to mass produce diy-ed boards and store them for later use.
I was thinking maybe experimenting with different black plastics (i.e. bin bags, etc) and possibly sticking it to the dried diy boards with spray mount adhesive. I.e. sprayed to the plastic and then sticking the plastic to the board.
I’m going to cut out some small pieces of board and coat them, and then see what it takes to expose them through different black materials. Also do a few control tests with boards exposed through a mask by tungsten, fluorescent and daylight.
I cant really do a tutorial justice until i have a camera ( and another can of resist).
Interest in photo resist has probably gone down hill, due to the expense of the pre-coated boards, and the difficulties associated with spraying your own.
No matter how well toner transfer can work out, it will never be able to recreate the same level of detail and repeatability that the resist can. I just couldnt see an institute such as a university ironing on bits of magazine paper!
Its off putting, having no information to work with. But i suppose once ive finished my experiments, i will be able to publish the findings for others here at the forums, and hopefully convert a few of you from the dark side
