Piezography: Ansel Adams and the inkjet print
"I simply do not believe their claim that they can get the Epson printers to print at greater than 1140 dpi - or if they can, their technical service department has never bothered to answer any of my queries on this."
That bit is pretty simple - the Epson printers print at 720 dpi. 1440 dpi = 2 passes; 2160 dpi (Peizo. driver) = 3 passes; 2880 = 4 passes. Thats why the registration and transport system is important and the better bilt printers are better.

"Piezography inks are not subject to the metamerism found in dye based inks nor dye/pigment inks. Metamerism is the tendency for an ink system to appear different under varying light conditions. For example, Piezography prints do not change dramatically under tungsten, fluorescent and incandescent light sources. The same cannot be said for ink systems produced by Epson, Lyson, MIS and others.
The inks used in the Piezography system are carbon black pigment inks. Pigment inks are much more archival than dye or dye/pigment based inks." The same can be said for the MIS pigment Quadtone inks. The MIS VM Quadtone inks also offer cooler tones and are as light fast.

Thanks, Michael and Tim, for your comments.
On the printer resolution, I have never been able to get the piezography software to make its four passes, despite multiple different configuration attempts, and I have never received a single reply to my various queries to Cone technical support on their web site. Eventually I gave up.
Re metamerism ; Michael's comments on the effects on different papers are interesting, although I do think that this is a very subjective area, where people will have different tastes and preferences. I have mainly been using a heavy matte white textured paper (Lyson soft fine art), on which the piezography inks do come across as very brown and warm.

I am not sure if you are still interested in pursuing this, but if you ask a question on the Piezography Users Discussion List at http://groups.yahoo.com/group/piezography3000/ someone (either a Piezography support person or a user) will probably answer it. Despite the group name, this is for all PiezographyBW users, not just for Epson 3000. Also, there are frequent updates to the Piezography software available for download from their website.
