Digital BW, The Print

Sorry to disturb this very interesting thread, from time to time I may ask some stupid question but it is the way to progress, so what do you call "swatch" here?

Many thanks

Michel

  I don't have the knowledge to address some of the above. A list member
  like Austin could, he has written printer drivers.
  However, linearization, or good profiling, addresses some of your
  points. Dot gain in particular.
  Your comment about changing K with swatch size is interesting. I've
  never seen that happen in my testing, and it sounds like something is
  amiss.
