A very nice process but elaborate. The Color Carbro process that was the next step even more. To mention; Paul Outerbridge's images in that medium.

On dynamic range, between Dmax and paper white, today's pigment ink inkjet printers do a splendid job too. With way more control and that in a convenient way. Longevity of the prints can be extremely good too, depending on the papers and inks used. Pigment particles are meanwhile all coated with a polymer and for finishing there are print protection sprays to slow oxidation of the prints even more. The black and grey ink pigments of 6-12 inkjet ink sets are also carbon based, some like the HP Vivera pigments are really neutral in color where normal carbon pigment is somewhat warm. Above all independent testing institutes like Aardenburg-Imaging.com show what the main risks on longevity are and which combinations tested well.
For B&W inkjet prints Paul Roark did a lot of developments on customised color printer solutions that are explained on his site and that are way more affordable than similar commercial solutions. One process with plain watercolor Arches paper is probably very time resistant but will have less dynamic range. www.paulroark.com/ _________________ Met vriendelijke groet, Ernst
