Can read on normal media. Since transparent media is obviously transparent, that you need to either have backed or else do a manual test for backlit media. This means you can create your own ICC color profiles in the comfort of your own office. This means that for every media and ink combination you now have the International Color Consortium color profiles. Since MacDermid-ColorSpan also owns Kilborn photographic media company you can expect a good combination of ink and media.
Every ink works best only with certain media.
Some media works better with specific inks and not as well with another ink. So if you get the ink and media from the same company then the combination is widely documented to produce superior results than if you merely use some miscellaneous media. With my early model Encad, which lacks a dryer, I can appreciate the sophisticated dryer which is part of a ColorSpan DisplayMaker. Anyone who owns a current model of ColorSpan will want the tilt-up printhead carriage. This means you can clean the ink cartridges without pulling them out individually.
