I, too, have many test reports. But in a recent article on color print fading, I believe you said Cibachrome prints fare less well than Kodak's Ektacolor 74RC prints. I believed the information I received that the azo dies used in Chibachrome are so stable that the prints are essentially permanent.

Of course, there's one very simple solution. Publicize each manufacturer's warranty. I'll never see it, but I'd dearly loe to read this article: Who does not tell the public that their prints fade and that they are not liable ? A: There's a little misunderstanding, here. In the article on fading color prints, I said that, according to research studies, Cibachrome's prints when stored in darkness were "essentially permanent." I added that, when the prints were exposed to light for long periods, they fared less well. Meaning less well than when stored in darkness, not less well than Kodak's 74RC prints. While it's true that no one has yet marketed a competitively priced color print with archival permanence, it's my understanding that Cibachrome prints are by and large the most nearly permanent color prints available.
