QTR-Quadtone RIP

sort of a basic question from a very newcomer, given a printer like
the epson 2400, which seems to have a good preformance for black and
white printing, is there any aspect of a print that will suffer some
sort of hindering when printed as an rgb document previously toned to
taste from the original grayscale?

I'm assuming that a printer like the 2400 uses only 3 cartridges
(black, light black and light-light black) for printing a grayscale
document, if the document is toned (by toning I mean sepia or similar)
then the document becomes rgb and, therefore, the printer should use
additional color cartridges.
 
thanks,
 Rodrigo

Hi Rodrigo

I don't have a 2400 myself (I have an 2100), but perhaps I can answer 
most of your questions.

Actually, this is not the case. The light black and light-light black 
are not neutral themselves. Other ink cartridges are used to get a 
neutral gray. Prior to the 2400 this approach did not work very well. 
The only alternative was to use special gray ink sets. The 2400 has 
been a great breakthrough.

You may get more color inks, but as pointed, you already start with 
color pigments in the first place.

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
