I think I've asked this before, but I don't recall ever seeing a response. What exactly is the difference between a dye and a pigment? Is it a difference in chemistry? Or is the distinction only in how the colorant is applied, with dyes diffusing into the paper and pigments sitting on the surface (bound or encapsulated with a carrier material)? -- Julian Vrieslander <mailto:julianv@mindspring.com> - Turn off HTML mail features.
