For this kind of look, with gum, you need to use a four-color process with
screened separations. Results can look like dye transfers or even
chromogenic (so-called "C") prints, from a distance.

Be careful with your choice of pigments however. Some years ago I had an
exchange of correspondence with someone making such prints... He bragged
about the prints being permanent because they used the same pigments used
in printing inks... After I informed him that 99.9999% of printing ink sets
had had least one color that was highly fugitive (typically the yellow) he
interrupted the exchange...

Those with such prints in their collection should keep an eye on the yellow...
