Who knows how the transfer and inkjet image on the glossy surface of cardboard?
. . . I mean, other than printing on a different paper then does a cut and paste. . . I’m for a transmission medium that is compatible with inkjet-looking prints. Or a special paper with metallic gold / silver finish
Take a look somewhere like Staples: they do lots of different papers in lots of finishes for all sorts of printers. I got some lovely silver paper from them last year for my Silver Wedding celebration invitations.
