Cibachrome has been around for 50 years or so (1969)
Introduced in 1963, with four improvements up until 1971.
My own 'beginner' prints from 1977, both raw unmounted and framed and displayed are still here, and on my gallery wall. Later master printed images are even more spectacular. These are spot-illuminated in the gallery, and on the opposite wall are the hybridised RA-4 colour prints. Hmmm.
Two of the variants of Ilfochrome are
not archivally stable. These are Ilfochrome Pearl and Ilfochrome Rapid, because they are RC based papers, not the polyester/black based Ilfochrome Classic high gloss material from which all tests for archival permanence are conducted and affirmed. Dark storage and/or conservation-framed display has been quoted at several hundred years.
Colour variations from digital vs the all-analogue Ilfochrome Classic process are fundamental to the process undertaken. Of IC, the high contrast and saturation of the Ilfochrome Classic gloss material also depends on very well exposed transparencies; too dark and shadows will be large swatches of black nothingness; too light and highlights and midstones will be stoned completely. Unfortunately this is something that too often did not get through to amateurs using Velvia and Provia so we saw a huge number of plainly awful images going through to print, versus the images of Peter Lik, Peter Dobre and Ken Duncan, among many other Australian luminaries.
The digital version of Ilfochrome Classic print production on the medium-contrast grade material got around the irksome problem of 'tidying up' the erroneous rendering of the red channel on Fujifilm transparencies (chiefly Velvia and Provia), with recommendations at the start that Kodachrome be used where a lot of red was involved in the image, very especially for the all-analogue print process.
