The longevity of the Claria dye inks in the 1400 are quite good. Around 100 years, almost as good as pigment. The ozone numbers are still a bit low, I think it was 9 to 15 years? Forget the exact number.
I would not hesitate to use the 1400. Yes, better gloss, less gloss differential, less metamerism, less bronzing than the pigments. Although the pigments are very good.
The dyes are not quite as good on matte in some cases. With the new fiber papers, many are abandoning matte printing.
Both good solutions to be honest.
