Digital BW, The Print

Tyler

Many thanks for your advice.  It looks as though the solution may be to
substitute an Eboni cartridge, however you have me intrigued.  What would
you generally use underprinting for if it is not to increase Dmax?  How
would you generally underprint?  I am not sure whether this information will
be of use for either of the RIP's that I use; QTR and Bowhaus OPM, however
it might be helpful in future.

Regards and thanks in advance.

  David, there are a number of reasons to underprint K with specific setups,
and increased
  Dmax is not necessarily the intention, or the result. It depends on many
things, the
  characteristcs of the inks and papers used for starters. Also, your driver
may or may not
  have a usable way to accomplish it.
  So, even if you can get your setup to do it, results may not be up to
expectations. Might,
  might not.
  Maybe someone here has tried simply substituting Ebony into that one
position, it may be
  the simplest solution. Certainly the easiest to try initially.
