Digital BW, The Print

Paul,

  Thanks for the detail answer. Sorry I did not make the question clear
enough. I was looking at QTR 2200 profiles for UT7 inkset. I found majority
profiles are using 3 or 4 inks only and the rest 3 or 4 inks are marked as
not used. For different papers and tones QTR selects different inks but it
rarely uses more than 4 inks for any given paper. That is the reason I
assume we only need 3 inks to print to papers like PhotoRag and EEM for one
tone and 5 inks for cold and also warm tone.

  Is it possible, using Epson drivers we need more than 3 or 4 inks, but use
QTR we need only 3 or 4 for each paper? If that is true we can use UT7 in 4
or 6 color printers too - just pick and install the right ink.

  The reason I asked those questions is because I have plenty UT7 inks and
would like to try the ink on my smaller and less colored Epson printers. I
need to figure out which ink(s) to be used in 4-color printer and which
ink(s) in 6-ink printer. And which can be left out.

  Thanks,
  - philip

  No, UT7 needs the cyan and magenta hextone channels, in addition to the
  black ink.  It has light and dark warm carbon and cool toner inks.  A
4-ink
  printer only has 3 spots aside from the black.  The UT1 is the
variable-tone
  inkset that will work in a 4-ink ("quadtone") printer.

  The yellow position is the only one that is really optional and open.  If
  you are using a rip, you can also do without the LK.

  With the Epson driver, you probably could put almost anything in the Y
spot.
  To turn on the black ink with the Epson driver that ink does need to be
  "full-on" in the curves set at 100%.  While the black ink is substituted
for
  all the midtones at that point, there is a slight risk that too high a
gamut
  ink in the Y position would affect the tone of the image in the deep
  shadows.

  You can buy the inks in bulk or by the individual cartridge.

  >   MIS said EZN has only two different inks.

  The EZ midtone inks are neutral or warm.  That's it.  They both have the
  same density.

  > How about UT7? All seven are different inks?

  Yes.
