Digital BW, The Print

Hello Shilesh,

>Does anyone know the ink usage with ABW in a 4800 printer? Specifically, I would like to know if full strength C and M inks are used within +/- 20 points of the color wheel tint picker.

I think the answer is yes.  I have tracked my 2400's ink usage from day one (about 4.75 years now) and here's the results in order of % usage (based on number of carts used).  Most of the time I use a slightly warm of neutral tone with ABW settings such as (+2h,+8v).  This chart shows some C and M use.  I'm assuming that the 4800 usage will be similar to the 2400.

LLK...17.9%
LM....16.6%
LK....15.5%
LC....14.1%
MK....11.5%
C..... 8.9%
Y..... 8.9%
M..... 6.4%

Sub groups look like this:

3 K's = 44.9%
LC/LM = 30.7%
CMY = 24.2%

Regards,
Clayton
