Weren't the original Iris printers based on dye inks? If so, those Giclee prints made in eighties and nineties might be beginning to fade by now. May be that's why people are now flocking to the Archival Pigment Print term.
Worse, they were also not very waterproof from the beginning. Which gave the term giclée a bad reputation in the musea. Musea backed off and asked for C-prints or Cibachromes. When I first showed an HP Z3200 print to the graphic arts conservator of the local museum here, I put the print under a tap and left it to dry there, asking the next day whether he observed bleeding of the colors. That is why I tell people that ask for giclée what we do today with pigment inks and inkjet papers and why I call them pigment prints.
The Iris prints made with uncoated Arches papers etc and Ilford Archive (dye) inks were the most fade proof but still way less fade resistant than the pigment inks of today. Lyson made a mistake by introducing the Hahnemühle inkjet papers with inkjet coatings (relabeled) for their version of Iris dye inks and that was the worst combination, something with the Ph grades not being compatible. They repeated the same for the early Epson 9000 etc printers and the Wilhelm tests were bad so they put their own misleading tests on the Lyson webpages.
The term piëzografie over here got some inflation too. It is used for color prints as well now and the prints are made on thermal head printers these days, no piëzo head involved.
