I think museums, libraries, better galleries, major auction houses, and conservators already have such standards for identifying the final medium, and there doesn't really need to be a new trademarked system. Yes, there are emerging technologies and companies branding inkjet products using the names of traditional processes, but I think that in the museum and collecting world, the need to distinguish is widely recognized, and no one is mistaking a "Carbon" inkjet for a real carbon print, etc.
