Daniel,

That the Epson driver is using the channels at full strength 
doesn't surprise me given the gamut of that inkset. Epson makes a 
color printer in the first place to satisfy the customers and the 
balancing act of getting nice greys as well is something for the 
pros. Getting nice greys only is yet another niche in the market. 
  But not so niche as I thought some time ago, this mailing list 
has as many members as the Qimage list :-)
