Digital BW, The Print

It is a pure greyscale mode on the Zs, if the ACS menu is kept on default no color ink is added, no composite mixes for greys used. Some matte media presets use MK + PK + Grey + Light Grey. On a Z3100 it will be linear for a calibrated paper. If you add color in ACS to change the B&W color tone the linearity is lost too, it just adds color ink on top of the grey ink base.
