I think that a point that must be made is that ALL reflection print materials have a minimum reflective density of about 0.1 in all three colors. This is just due to the laws of physics and chemistry. Baryta and Titanox have that characteristic. You will find this to be true with both digital and analog prints. There is nothing that can be done about it.

Now, digital prints maintain that value because if there is no density, then the ink or pigment is not applied.

With analog prints, all areas of the paper are treated with all of the chemicals and there is always some level of fog and stain. The fog is just normal random grains that develop and the stain is due to the process chemistry.

So, there you have it.
