Re: Masking, part 1

Title: Re: Masking, part 1
Try and remember that what happens in the USA does not happen elswhere so the fact that there were additional suppliers in the USA means nothing to a European.
Equally you should assume that there are/were more than one set of four colour inks available and indeed I used a set from Japan that had abetter than average Cyan. However that does not indicate that most users were into commercial production volumes and had neither the time nor inclination to use specials that required different masking techniques.
In addition I can assure you that whatever the limitations  of Kodak dyes I never claimed theoritical perfection but they were vastly better than printing inks.

I would have to disagree with the last statement; no such across the board assumption should be made.  There were several alternative dye sets to Kodak's available to printers during the 80's, most notably the set produced by Morely Bard of Bard Experimental Enterprises of Pomano Beach, Florida.  His was basically a one-man company, who produced a set of 10 dyes (3 cyans, 3 magentas, and 4 yellows).  Archival improvements were addressed as well as spectral characteristics; i.e. a worker now had the ability to choose a particular dye based on the color requirements of the image.  Also, although Kodak's dye set was quite good, it was far from being perfect.  It was impossible to reproduce a neutral gray scale from an unmasked silver step tablet, and printers always complained that the yellow was too warm...
