Digital BW, The Print

When creating the profiles each colour is considered one channel, so 
light cyan and cyan are seen as one colour, all of the blacks are also 
seen as one colour. We therefore create 6 channel profiles - CMYKOG 
normally.

>> We have a Roland D'vinci 64" printer which runs currently with 5
> blacks
>> and a full Hexachrome set (12 different inks in total). We print
> mainly
>> for very fussy photographers and artists. Our alternate printer is
>> currently a 9600 running via Imageprint 6. There is a noticeable
>> difference in output quality for both B&W and color images between
