Digital BW, The Print

Peter,

Your question was - "What is 'traditional' carbon?" I was giving you that
answer. The gelatin in which the pigments are suspended hardens where
exposed to light, therefore making it a light sensitive medium. The
unexposed areas are washed away and the result is an image. This is over
simplified but you can find detailed descriptions of the process online. I
was not trying to address whether they are the same pigment or whether the
carbon in 'Carbon' or 'Carbro' prints has any relationship to carbon inkjet.
As I said, I don't know.
