Of course this is what I meant to do!
Otherwise it would be a silly thing to do.
As someone suggested, the ink quality is the determining factor for color
gamut reproduction, which means that with better inks, a press could
theoritically print a bright violet the same as the Epson can.
That's probably what the Hexachromy was made for, but this process is
too expensive for a standard advert print.
