Digital BW, The Print

Those who have been following the "more to the story" threads may 
know that it was originally from an experiment posted on the 
Piezography website (see message 21633 for the link).  The posted 
images were of great interest to the Epson driver user like me (on a 
1280), and I did my own experiment.  But the the images on the Piezo 
site continue to bug me.

The experiment I did was a major-eye opener.  Cone says: "Curiously, 
the darkest position (cyan) is used to print the lightest tones and 
yellow position is used to underprint the black ink which is the 
predominant ink in the midtones and darker."  Whether, it is a 6 
color printer I used or a 4 color printer that Cone used in his post, 
the Epson driver DOES NOT use only cyan ink in the highlights. 
Rather, it seems to use ALL color inks (makes sense).  How do I know 
that about Cone's 4 color printer?  Well, look at the Cone images: 
The only place where you see pure cyan ink is the 100% to ~ 70%  of 
the Piezo print. What you see there in the Piezo print IS the true 
cyan color of that printer, as alluded to by Cone.  But that is NOT 
the color (density or hue) you see in ANY part of the Epson driver 
print!  So other inks are being used, and I am guessing all inks are 
being used.  What does that mean?  Does the fact that the Epson 
driver uses more inks than the Piezo driver for any given tone make a 
difference in the final output?  That is the question.  Will one of 
these drivers produce smoother gradients?  Less textured dither?

More to come, as I do more experiemnts....

May your gradients be smooth
