Hi,
        there are a number of perceptual space algorithms available. They all 
rely
on the profile being provided. My inclination would be to provide an accurate 
printer
profile, use the default Optimised Farthest Point Sampling but since you aren't
interested in profiling the printer itself, set adapation to 0 (-A) so that it
generates perceptually even points.
