    Hi,
    Im thinking maybe I might get a new printer,
    you seem to be able to get a colour paper printer with very impressive stats
    for less than the cost of a few cartridges,
    but what can they do nowadays in terms of printing on awkward surfaces ?
    it would be nice if I could print a 50mm codewheel with 2000 lines on
    tranparent film,
    nicer still if I could print onto front panels,
    best of all if it could print etch resist straight onto copper.

  2. Find a good used plotter on eBay.

    you dont mean a pen type plotter do you ?
    I need about 2400 dpi to print my codewheel with a good number of pixels per
    line,
    some cheap inkjet printers spec at >5000dpi !
    some print onto cd's but some say they need special cds wich apear to have a
    paper film ontop, not sure if they all need that type, some have waterproof
    ink but on some types ive heard this just wipes off some surfaces.
    dye sub might be better or laser ... with a flat paper path ofc

  4. You don't need pixels to draw lines. And what inkjet will draw resist for
    you?
    White paint, but they aren't as good as they say they are.
    They can be a bitch too.

    Hmm I dont think pens come in widths of < 0.04 mm or do they ?
    you do if you want to use the most common type of printer.
    the alternative is lines per inch wich is much the same thing.
    well thats the question IM asking, presumably ones that have acid resistant
    ink,
    although thats probably asking for a bit much of waterproof ink,
    maybe it can be used as a tin platting mask instead or to mask some other
    etch resistant stuff,
    fused toner is etch resistant i beleive, no idea about dye sub
    not many things are ... sigh.

    OMG that looks too good to be true !

    so ...

    a) A modification to allow the pcb to pass through an inkjet printer such as
    a c84,
    although if a printer wich takes cd's already this might not be necessary

    b) use the alternate inks,

    c) heat the printed pcb to 230'c wich cures the ink so it becomes very
    resistant.

    etch as normal.

    wonder if the stnd waterproof inks will become etch resistant at 230'c ?

    There was a longish thread about this in the Yahoo homebrew_pcb group.
    It does take a modified printer (IIRC a C84) and a bit of preparation
    of the blank. Seems the ink brand is rather critical too.
