If you compared it to diluting HP PK, I always had the impression that 
the HP PK and the other Vivera greys are quite dense compared to other 
ink set grey inks. One of the reasons could be that the substitution of 
CMY grey mixes with a heavier grey etc reduces ink lay down more. There 
has to be a balance what is visually acceptable and best for the paper 
coating but the Z3100 in total has hardly any composite greys in color 
prints left and its droplets vary between 4 and 6 picoliter. Drying time 
is fast, color stabilises fast and that is also desired for the internal 
calibration + profiling if done in one run.
