Digital BW, The Print

I am happy to report that after testing every single channel with the
21 steps file using custom curves in QTR that Paul Roark was right
(again? ;-) ).

I was surprised to notice that the worst channels in my R1800 where
MK, K and GL. Then C. The best where Y and M followed closely by R and B.

So I am now using 3MK with these channels: Y, M and R.

I assigned the largest values covering curve to the Y channel. Then
the 2nd one to M and third to R.

It prints... amazingly better! No more micro banding and seems overall
a bit smoother too.

I imagine R1800 sample variations do exist and that those who are
having issues with their current channels selection might benefit from
this channel testing and swapping.

Thanks Paul!

Denis
