Digital BW, The Print

Thanks Paul for your answer. it is very helpful.

  For most papers we only need about 3 or 4 inks/positions from UT7 so it is
possible to use UT7 in 4 or 6 color Epson printers. Is this correct?

  Also is it possible to buy only 3 inks if only use PhotoRag for warm or
cold tone, and 5 inks for both? And keep other position with original Epson
inks?

  MIS said EZN has only two different inks. How about UT7? All seven are
different inks?

  Thanks,
  - philip

  Philip,

  Different people use different ways of figuring dilutions.  MIS often, for
  example, just assigns arbitrary percentages just to signify what relative
  lightness the inks are.

  I do not dilute the high-load Eboni or MK, and expect the actual loads are
  highly proprietary.  For the B&W inksets, from my perspective, the 2200
and
  the introduction of the LK density and separate Photo Black gave me what I
  consider ideal starting inputs.  As such, the dilutions I work with are
now
  of these inks -- which are not uniform in themselves.  That is, company X
  Lk-1 does not necessarily equal its LK-2.  Same with the PKs.

  So, I can't describe the dilution schemes I tend to use in terms of an MK.
  It is not what I start from.

  With that caveat, the 32% first step dilution is close to a typical Epson
  dark-to-light midtone ink dilution.

  I usually use a dark gray density that both seems to work the best in
  repeated empirical experiments of mine and is a standard that started with
  the PiezoBW inkset -- the C position density.  It is between LK and PK,
but
  the exact ratio depends on the LK and PK involved.  (Note that MK is a
  higher load ink than PK.  PK loads, all else being equal, are limited by
  "dusting" or glossy loss -- which is not a problem for an MK.)  Virtually
  all of the inksets I use or recommend have dark grays close to this -- the
  monotone FS-C, UT 2 & 7, UT-R2, etc.  It is something of a standard.

  On hextone printers I want the inksets I use to be able to utilize the
Epson
  driver.  So, the step from the dark to light midtone inks (like C to LC)
use
  very close to the typical Epson step up.  That seems to fit the drivers
and
  papers best in my experiments.  So, this is another one of those de facto
  standards that I work with whenever possible.  I often don't start with
the
  standards, but end up close to the same place based on observed printing
  results with different experimental densities.

  For greater smoothness the FS-Y position light ink is used by some, and by
  me on older printers.  This is very light -- lighter than LLK.  The
  dilution-to-density relationship is very non-linear.  So, the typical
Epson
  midtone dilution ratio does not necessarily hold at the ends of the range.
  Printer dot size and other factors make experimentation the best way to
  optimize the system.

  The 4-ink printers present some different factors.  They haven't been
  designed around a midtone cross-over.  The standard hextone inksets are
not
  optimized for them.  I recommend partitioned monotone qaudtones for the
  older ones, and the EZ (all equal midtones) for the C86.

  Hope this helps.
