By contrast, Cibachrome has the colour dyes pre-coated into the emulsion at the manufacturning stage, the processing removes those not required for the final image. I hope I have made my point.

I believe it is called a "dye-destruction" process. It has always been my belief that only the name changed when Ilford bought the Cibachrome name from Ciby-Geigy.
I would trust Les in this since he works for Ilford sometimes.
