Digital BW, The Print

Hi Jimbo,

Why do you have the 'preserve RGB numbers' checked?
Why do you leave the priority to 'Standard'?

One of the most important things seems to be the contrast ratio (the
relation between brightness and black level).
If you have a brightness of 80 cd/m� and a black level of 0,2
(standard), then your contrast ratio is 80/0,2 = 400 (400:1), while
matte paper has a contrast ratio around (200:1).
