I've been using PFP since it came out.  With a little fussing,  
repetition and tweaking I get fairly decent results with a variety of  
papers on an Epson 2200 and an R220, both with MIS Pro inksets.

Yesterday I tried to print an image that was mostly grey, with two  
faces, some flowers and a cross in full color. The image started life  
as a regular RGB image. I selected the soon-to-be-grey parts and set  
the saturation to zero (I also tried other B&W techniques).

When I print it with my PFP-produced profile, the colored sections  
look appropriate, but the greys are off and ugly. Midtones and higher  
tones look grey, but from about the midpoint down into the shadows  
the tones are nowhere near neutral.  Unfortunately I'm partly red- 
green colour blind (and hence tend to project green and occasionally  
red into/onto surface colours I can't see well), so even trying to  
describe the colour is pretty hopeless.

What is the best way to use the PFP system to tell me how far off I  
am on the different color axes I can tweak when building profiles?  I  
simply cannot rely on *seeing* that something is too yellow or cyan  
or whatever, although generally I can tell that something is "not  
right".

Thanks.
