[Digital BW] Re: PS VM curves is Picture Window

2003-10-22 by Jeff Randall

Based on my direct observation of the ramps and Swatchbook 
measurements of the step wedges, I concluded that the PS and PW 
curves were essentially identical for the FS/FSN 1160 partitioned 
workflow.  I did use up to 15 control points (red curve) for the PW 
partioned curves and this could have a significant smoothing effect. 
I, however, did not do exhaustive experimentation.

I'm looking forward to your results.

Thanks.
