Digital BW, The Print

Paul,

You are right about the new Piezo ICC ink order.  I filled one 1280 
cartridge with FS inks in that order, and was very quickly able to 
create a grayscale adjustment curve to linearize a 21 step ramp.  The 
wedge was smoth and certainly no dots. So, the new Piezo ICC inks 
likely can be used very easily with the Epson driver, without having 
to resort to ICC profiles or a partitioned workflow.

My understanding of the FS-E inks was that LC=1/3C and LM=1/3M.  It 
is, therfore a true "hextone" inkset (overkill, IMHO), rather than a 
quadtone inkset used for hextone printers.

Regards.

Shilesh
