I would say that may be true of their new resin encapsulated pigs, but, my understanding of optics says that generally if the surface of the paper is the glossies portion of the media, the deeper the inks goes, the glossier.. Am I missing something? I mean the Pictorico Glossy, as an example, has micro-ceramide particles that wick ink out of the micropores and into the rc layer, as I understand it, which would make those particles deeper, not closer to the surface... 2) This makes NO logical sense: "an extremely light resistant material protects the pigment particles and minimizes light damage" Ok, I'm game, if the resin is "extremely light resistant" how the heck do we ever see color reflected from it? Before anyone says something, it may be UV light resistant, that's not anything like what it says... Sounds like a marketing person, not a techie, wrote that presentation..
