Digital BW, The Print

Since there's been talk about the two Epson driver modes I thought
it would be worthwhile seeing how they compare in ink usage.
The following "prints" were done to a file and analyzed to see what
commands were being sent to the printer.

Comparison of ink usage from the Epson R2400 with Epson driver
Image - grayscale 21 step wedge
Paper - Velvet Fine Art
Quality - Best Photo (1440x1440)
Both prints use 2 dot sizes, percents are weighted based on drop size

Epson ABW driver - neutral
total	100%	dots 9,763,341 small 2,532,646 medium
K	31.27%
LK	26.15%
LLK	21.03%
LM	12.76%
LC	 7.92%
Y	 0.87%

Epson standard driver - Epson Velvet Fine Art profile
total	100%	dots 10,393,768 small 2,694,351 medium
K	32.84%
LK	49.40%
LLK	 1.29%
M	 3.25%
LM	 4.39%
C	 2.90%
LC	 2.37%
Y	 3.54%

Some observations:
ABW uses a lot more LLK --- 16 times!
ABW uses a lot less Y   --- 1/4 the amount
ABW uses no dark C and M

Interestingly this really supports the idea of replacing the Y
ink with a LLK ink with either driver.
