Sure. I tried some of my favourite Epson Premium Photo Luster and got so much ink on the paper it ran off the edges at first. I reduced the ink flow in the QTR pane of the print dialog and made it safe to print, but there was still metamerism in the black areas. I could see there was a need for a somewhat absorbent paper, so I tried some Innova watercolor paper next, but this came out grey and fuzzy, as if it was too absorbent. To be fair, they do say that to use a lustre paper the Gloss Optimiser must be included, and I don't have this.
The Inkjet Mall site says:
"Piezography Neutral K7 inks are seven dilutions of pure carbon pigments which create Lab neutral to the human eye when viewed under 5000k and printed on Hanhemuhle PhotoRag or Innova Photo Cotton Smooth. These papers have a white on which this achromatic effect is achieved. Choose a warmer paper or a cooler paper, and the Neutral inks will warm or cool. A wide range of color tone is possible in this manner. The end result is a perfect marriage of ink and paper. A perfect monotone is produced. Inks are designed to fade less than 5% and shift less than deltaE 2, both below average human perception. These are the longest lasting inks available. There is a zero metamerism effect. The pigment particles are ground using a proprietary nano-technology. The fluid base in conjunction with the pigment produces a very non-clogging formula."
I'm hopeful the Hahnemuhle Photo Rag will get it right. If not, I shall have to ask for advice.
