Thank you Ernst,
Of course BW is included.
So do you think that there is an obvious quality shift in z3100 prints?
With the diversity of printing you intend to do there's a general quality shift, there are no big steps happening at this level of quality printing, you count the small steps per printing mode and together there's better quality.
Before I unpacked the Z3100 I made a photograph of the equipment that I used till then, an Epson 10000 loaded with MIS 7600 inks for color printing, an Epson 9000 loaded with a MIS quad inkset for B&W, an old HP A3 HPGL pen plotter on top that I had converted to scan targets with a Spectrocam.
The single Z3100 replaced all that + it can print gloss color without an ink switch. More grey inks will not only make your B&W prints better but it also keeps neutral areas in color printing better, a better gradual smoothness on the neutrals too, metamerism should be lower (less composite grey).
There's probably a bit less ink used per printed page on a 12 inks machine compared to an 8 ink machine as the RGB inks replace the saturated MY, CY,CM mixes with less ink like composite greys are replaced by less black (grey) inks. It is interesting to see that LM is hardly used on the Z3100, the red must take much of its tasks. LM is the ink most used on all CcMmYK printers.
