QTR-Quadtone RIP

Hi Joost,

many thanks for your reply, that was a lot of enlightenment. I should
now have a better understanding of how toning is achieved with a
printer like the R2400.

Apart from Tom Moore's document are you aware of some other resource
explaining, not perhaps the how-to, but the why-to's? I mean, at the
first reading of Tom's document it was a bit foreign to me that color
cartridges where involved for achieving a neutral tone. 

thanks again,
 Rodrigo
