Digital BW, The Print

Actually, I first realized that I had a problem with the spectrocam when I
was coating matte prints.  The spectrocam was topping out at a dmax of 2
when my coated prints were actually hitting upwards of 2.4.  I then went
back and checked calibration and realized that anywhere above 1.6 with black
the spectrocam was in accurate.  The further from 1.6 the worse the problem.
Photorag with any of the common BW inks is already a problem.  As Antonis
mentioned, the spectrocam will be inadequate for any glossy or semi-gloss
print with photo black...they all hit above 2.0...and the accuracy of your
shadow detail will be what suffers.  This will be a serious problem if you
get into using the linearization function of ink jet control.
