Digital BW, The Print

Todd, 

Am I understanding this right.....You are getting "inconsistencies" with MIS VM inks?

  I've noticed that my separation of lower values had diminished recently. I
  used all 4 of Paul's VMM11 curves (for Mac and 1160) to print out Tyler's
  Zees not long ago (in the files section. No better test I know of for tonal
  separation) with very good success. Today, with no changes to ink, paper, or
  workflow, I have less separation of my lower tones.

  So, I know it's not the quality of the curves that is at fault, or a
  difference between printers, or materials. The only changes that are coming
  to mind is climate, and printer usage, neither of which has altered that
  dramatically in the month or two since my excellent results with the same
  test.

  I find so much of this so terribly frustrating. The mysterious
  inconsistencies. Sometimes in smooth tones areas my prints will have a
  corduroy patterned banding (running perpendicular to the travel of the head)
  and sometimes microbanding or sub-microbanding (not real sure about what
  either of these terms really means, but what I get is fine white "etch"
  lines which run parallel to the print head movement. Very tiny, like little
  grain lines, which gives a mechanical feel to the print. Need to look pretty
  close to see it (but how close to subconsciously perceive it?)). Then other
  days these things are NOT present.

  Do other people get minor variance with their systems day to day or week to
  week, or do I just make my printer moody with my demands? (I think that
  would be my wife's guess)
