Etch Resist from InkJet Printer?

autodeskguest

I've got an InkJet Printer that will print on CDs and DVDs.  Is it possible

to print etch resist directly onto a PCB?

    I've never tried it, but I did a bit of research before I bought my

    previous printer. That's a while ago, so things may have changed.

     

    The biggest problem is that most inks are not water proof, so they

    will wash off in the etch bath. Some inks, I think HP's pigment based

    inks, can be used.

     

    The next problem is that the ink may not bind properly to the copper

    surface. Ink is intended to soak into the paper, but, again, some inks

    suitable for glossy photo paper may work.

     

    What it boils down to, is finding the right ink.
