I thought I was using the calibration step.  I believe the way I did this is to start the work around application, there is no button for 'color management' so I ASSume that there isn't any management going on (this is the reason for this app, correct?) and print from there (i, no Photoshop involved).  Anyway, I printed the min time for black on Saturday, step 3 (on a 31 step wedge) merged with #2, so I multiplied by .794*.794 to get the standard print time.  I printed the ink separation on Sunday as well as the min for black test.  Sat and Sun min for black are identical.  However, while somewhat close, there is no square on the ink separation test that matches the white strip that was under rubylith on the min for black test.  On review tonight, step #3 and #4 on the min for black test are pretty close; maybe I should decrease the time.  I will rerun the tests again, will print a new ink separation sheet to insure that I did what I was supposed to, and give it all another go.  Thinking I should also include the step wedge in the ink separation to insure same results as well (you how pd can be at times).  Thank you all for advice....lyle
