Digital BW, The Print

Hi Paul, thanks for all the additional info on possibility of straight
carbon being too warm. For the 7500/QTR I'm going to start out by
following the suggestion from your previous post of modifying 4k+cm to
have a very light grey instead of photo black (UT-3D dark and light
carbon plus LLLK in place of cyan/magenta/yellow; & keeping the black,
light cyan, and light magenta now in the printer). This way, if I want
to have only the carbon tone available and/or am unhappy with
smoothness I'll have the future option of substituting more carbon
dilutions for the lt cyan & magenta; meanwhile I'll have some tone
control available. 

Unless there is a reason not to, I'll flush the cmy channels
individually (by modifying the QTR calibration image) with Mediastreet
flush carts I have on hand; and rinse out the 3 MIS funnel fill carts
with distilled water.

For my 2200 I'll just take advantage of the MIS July sale and get a
CFS prefilled with UT7.
