I searched the site & didn't find anyone choosing to use Canon's own papers for fine-art printing on the Ipf 5000. I've begun with EEM & HPR, because I have plenty on hand; but I wonder about the papers that Canon makes/markets/repackages themselves.
The Wiki reproduces the table of Canon's many papers & surfaces, & InkjetArt's website lists two Canon 'fine art' papers as available from them: Canon Fine Art Enhanced Velvet, in 13x19" sheets; & Canon Photo Rag 308, in 17"x40' rolls. (Also some canvas, ugh.) They're listed as ProGraf papers, but does that mean they were made with Lucia pigment inks in mind, or earlier dyes?
I wonder if the Enhanced Velvet is like Epson's VFA, which is truly a fine paper if you like texture? And I wonder if the Photo Rag is a brother, sister, or cousin to Hahnemuele - which happens to sell for the same price? Is Canon Premium Matte paper better/worse than EEM on the 5000? (Price seems to be about the same.)
Or does everyone but me know there's a plague or virus in Canon's papers that keeps healthy photographers from using them?
