Digital BW, The Print

I swear I must just have different ink or something.  My Gray Value for
45/45 was 40 when I think yours is down at 20.  I am really beginning to
wonder if MIS have any QC or perhaps we are just doing something completely
differently.  I print the calib page with the ink limits set and then
measure the 100 patch on the combo and find the interpolated "% black".
