Digital BW, The Print

Robert,

Thanks for uploading your new OPM/IJC profiles.  I just printed some  
step-wedges for linearization with your warm and cool profiles for the  
2200.  The warm profile step-wedge was fine, but in the cool profile  
step-wedge no black ink was printed in patch #26 (100%) - just the  
photo cyan/magenta mix.  I noticed that your black curve in the cool  
profile does not quite reach 100% (goes straight up) - was this  
intentional?  Also, there is a single, isolated band (about 1 mm) of  
dark grey in the gradient above the #26 patch for the light black ink  
tweaks printout.  I was printing from OPM 1.02 and IJC 1.0.  Just  
wondering if the profile is corrupted or if there is a bug in OPM 1.02  
that might be causing this.  Despite these minor problems, the 60/40  
blend of the warm/cool profiles does indeed produce a very nice  
selenium tone on ISP.
