I've just purchased an Epson 4880. At least for now I will stick with Epson inks.

It has Black, Light Black and Light-Light Black cartridges ("3K" system) for printing black and 
white images.

Using the 3K inks is controlled in the Epson driver, and called "Advanced Black and White". It 
allows considerable adjustment, but this is *within the driver itself*.

My understanding is that to use ABW / 3K printing you "let printer control color" (by means of 
the ABW adjustments). Thus, there seems to be no possibility for using "color profiles" via 
Printfix Pro to tweak the 3K black and white printing.

Is this correct?  If so, is there any way that I can use my spectro-photometer (is that what it's 
called?) to tweak the ABW setting for papers that the printer does *not* recognize?
