I read through a plethora of posts, but could not find a yay or nay
answer to the question:

Can inkjet ink be used as a direct photo resist?

I was thinking of the Epson R200 for an upcoming CD project, and
hoped it could be used to do homebrew PCBs too.

I've been watching for any mentions of this in posts.

I too have not seem very much action on this area.

There has been talk of specialty inks being used that will mark metal.

also, it seems that standard inkjet inks do not really adhere to
metal but bubble up.

There was talk about pre-treating boards to accept the inks more
readily and talk about getting the Stadler ink for printers.

Since there are already dot matrix box printers, and metal barcoding
machines that print from bottles

I am hoping someone figues this out.

It is a shame that we can't print with lasers directly onto PCB's.

I saw mention somewhere on the web of someone who was using a brief
ferric chloride etch prior to applying their transfer. I would think
that would leave an excellent surface for adhering most anything.

Thanks for the input.
