Clair is right. "Resin-Coated Chromogenic Colour Print" seems to be the full technical term. I just looked it up, as I wasn't sure anymore. It's an expensive name for a color print. However, I also found (funny or not) websites stating that C-print means COMPUTER-print, explaining that the prints were made from digital files and printed with Lambda-prints.
