Re: [Digital BW] ICC v. Transfer Function in Epson driver

They are not clipped on your monitor.  Adobe CMM maps to the monitor black
point and performs BPC.  Again, to get from a big gamut to a smaller one you
must either compress or clip.  Absolute colormetric clips.
Relcol/perceptual with BPC does not.  Without BPC it would.  Check your PS
color settings - although I think I heard once that these settings do not
affect PCS to display conversions which are always set to relcol and bpc.
