[Digital BW] Re: Need help - PiezographyBW and Dot Gain Curve

Loris:

Sorry, all I saw was the FS-N part of your inkset system.  There is 
no problem with the FS or FS-N inksets and the 1160 RGB Partitioned 
Workflow. The workflow was designed for these inks.  Any of the 
inksets/workflows that rely on a toner ink such as VM etal. will not 
work with this workflow.
