Excellent results and I hope they carry over to the ipf series.
I don't understand leading off with this printer though -- I thought it was a dye printer based on the model number.
I do wish they'd use more standard papers for comparison. Take plain old photo rag (not a special HP version) for the art paper, for example. A non-denominational luster/semi gloss paper gets more difficult as I think Epson's luster is probably the most commonly used but how about Ilford's smooth pearl? I don't know anyone that would prefer Canon's semigloss over either of these. Might be interesting to try and isolate the comparison to just the inks, for all the brands/models.
Reading the fine print you kind of wonder why Kodak even bothers anymore.
