I just thought of an different way to make PCBs with an inkjet printer that
might be worth trying. Instead of using special ink printed onto the copper,
which is then cured, how about coating a standard resist-coated board with
gelatine, as is done with with inkjet transparency material? This will then
accept a standard ink, and the artwork can be printed directly onto the
gelatine surface. The board is then exposed to UV light in the usual way,
and the gelatine and ink washed off in hot water. The board is then etched
in the usual way. Very fine line widths and good definition should be
obtainable, because the artwork is only separated from the resist by the
gelatine.
I feel that the technique could work, and could give very good results.
