Subject: Re: [Homebrew_PCBs] Question for Stefan

you are asking the wrong guy i believe.

i only read of the printing directly with inkjet here in this mailgroup i believe.
i read that you need a inkjet with flat paper path.
i read about finding the acrylic floor polish, this seems to be difficult.
i read that the floor polish can be cleaned off with ammonia.
i guess myself that it is not much different to diluted water soluble clear laquer (as the polish also
is water soluble when liquid and not when dried up)
don't remember the brand but know i've never seen it here.
the polish is transparent i further know.

this is all i know of this process and this is all read from here (i believe, maybe i read elsewhere)
so you may use the search function and easy find the postings.

to plot on directly on copper i can tell you a lot, i'm currently improoving this.
you need:

pen plotter
plotter pen ;-) don't bother with steadtler 313 or 318 no good results, linewith depends on speed and
is too thick. buy yourself a carbide metal tip pen with 0,28 or 0,18mm, best are X grooved tips.

now the most difficult:
get you pc and pcb software to correctly send a plotter file (often hpgl needed).
this is not so easy as it sounds.


if you need any further help with plotting i will provide it but of inkjet printing i also have only
heared of.


regards
stefan
