Digital BW, The Print

Carl I'm using IJC 1.01 and OPM 1.02b.  I just downloaded the profile from
the web and printed a step wedge through OPM with the profile and it was
fine.  Likewise, I printed from within IJC and this was also perfect...so
there must be a bug.  I'd contact bowhaus for an update.

Sorry,

Robert
