Digital BW, The Print

Walter,

Peruse this first:

There are 4 things to using ABW, and each can be sensitive to the paper you use; so they will need to be repeated for each paper of choice.

(1) Color hue. This is the easiest. Just print using ABW by selecting the pre-defined or make your own choice with the color wheel. You should find a look you want with the color wheel.
(2) I have heard that using the "dark" setting gives the most linear response for a gray gamma 2.2 image file. This may become moot if you are using a non-Epson paper and linearize later.
(3) Getting the best Dmax. This entails getting the correct K ink limits on each paper.
(4) Linearize the L response between paper white and Dmax.

If you have a means of measuring density, this whole process becomes really simple. If you are not inclined to follow this more "measured" path, then the link above should get you very close on most papers that Clayton has kindly reported on.

There are also other tutorials and treatesies online on the use of ABW. Try googling "Eric Chan ABW".
