Hello Clayton,

I've tried 2KBO printing on my Epson R220, following the steps you've
described. I have a pint of Ebony black and appropriate carts & chips,
 so it was an easy setup.

After a nozzle check I did a print head alignment examining the
printout with a magnifying glass then proceeded with the QTR Ink
Pattern Page printed at 2880. Examination with a mag. glass showed the
yellow channel to be coarser, the black channel looking just as smooth
as the others. I chose the LC and LM channels, made the primary and
secondary curves using the CJ-2KBO-R200-Ordered.ACV file.

I also made another primary and secondary curve in QTR using the K and
LM channel. Another nozzle check and I was ready to print the same
image on Premium Matte 210gms C2S using both QTR configurations plus a
BO print as control.

First thing I noticed was that the light areas of the 2KBO prints had
more density than the BO print. The  LC/LM channels print had more of
the grain effect, the K/LM print less grain (?) with the BO print
being the smoother. All prints had the same tonality.

But then I noticed paper white (no ink) in the two 2KBO prints at
exactly the same spot: an outdoor light cover with strong horizontal
lines and also around a lozange shape street sign. So I printed again
on EEM (warmer tone) and the same artifacts appeared at exactly the
same spots. Another BO print did not show these artifacts. Printed a
nozzle check again just to make sure. 

So, there you are. I'm not sure what to make of this. Hope you can
light my lantern.

Cheers,
Andre
