Digital BW, The Print

Yesterday I wrote:

Using Moab Entrada 300 Gm. paper in the Epson 2200, the results are
rather pleasing. As expected, the tone approaches sepia, but with the
sunlit image of an antique market, the tone seems appropriate.
Compared with the same image using all seven inks with a profile for
Epson Enhanced Matte, there is very little difference under a 10x
loupe in highlight dots or apparent resolution. Tomorrow I will look
at the print in sunlight and see if there is any metamerism, as well
as print the image as BO through the Epson driver.
   -----------------------------------------------------------------------

This morning I printed the image as black only with Epson UC matte black and 
find that the image is much coarser under the loupe than either the normal 
seven color print or the two color black and light black, but still looks fine at 
arms length.   The color is still brown but much closer to neutral than the 
2-color print.   Clearly the light black is adding a considerable brown element 
to the mix.   Max density is 1.62 +/-0.01 on an x-rite 810 after drying on 
all three wedge tests.

Now to do the Eboni black 2-color version and see if the two color idea has 
any useful merit over straight Black only.

This may all be academic as IJC allows wonderful profiles to be created with 
any number of inks up to seven, but it has been an interesting exercise.   IJC 
linearization does give separation in all 26 steps of the wedge, and a much 
more consistent group of prints using seven colors.

Cheers and thanks to all,

Angelo Dounoucos
