  Subject: [Digital BW] Jon on the PiezoTones


  Hi All,

  Thought the list members might be interested in a post by Jon Cone over on
  the PiezoPro24 list.  It deals with some users' questions regarding how to
  describe the inks to prospective buyers of fine art produced with the PT
inkset,
  and some of the technology behind the pursuit of print longevity...


  Dave,

  These are not such troublesome questions. What a lot of people do not
  realize is that carbon is not BLACK. Carbon Black is in actuality a very
  dark dark brown. In larger masses such as globs of paint or printers ink,
  the carbon mass appears to be black. But in the thin film of inkjet ink,
the
  mass-tone appears black. Additionally, ink chemists have had a tough time
  suspending carbon black with other pigments. This was then. So they used
  dye
  in small amounts to neutralize the warmth of the carbon and arrive at a
more
  neutral tone.

  The newer inks use pigments in place of dye. The technology is smarter. 3
  years smarter.

  We never advertised the PiezographyBW inks as pure carbon. We have
  always
  been very forthright about their properties and early on suggested which
  papers would cause more warming from the loss of dyes from light-exposure.

  Archival?? This is a two-edged sword. Archival means can it be preserved.
  LONGEVITY implies display life under light. Use each term with intention.

  Archival - yes under the right conditions.... AN EXPECTATION? NO. A
c-print
  for example is not archival - not even in a freezer. IT has a chemical
life.
  Carbon inkjet prints can be archival however, unlike a c-print. With the
  older inks - they do not have the stable longevity of the newer inks.
  PiezographyBW's dye content does not have the stability of the PiezoTones
  which use pigment (very stable pigment) as a colorant to offset the brown
of
  the carbon. So PiezoBW inks warm (nicely) to their final carbon tone
  depending upon the paper to varying degrees. Then they stay that way.
  PiezoTones are intended to stay their tone even under extreme light.


  PiezoTones are a contemporary Quad Ink which uses technology which has
  not
  previously been made available in an inkjet ink. We looked at stability
and
  longevity in addition to archival nature. While the photographic and art
  world separated these conditions - inkjet and digitalphiles apparently do
  not. To them it meant the same.

  Are both inkset families archival? Yes.
  Do they both offer the same stability? No.
  Do they both offer the same longevity? No.

  While we have blue wool data of the new inksets and these are very
  impressive, they do not indicate display life. We took responsibility as
  manufacturers of PiezoTones to do complete testing with RIT at great
  expense. We will be able to give direct comparison results in a matter of
  weeks. And the results will be in display life rather than in factors.

  When?

  We hope the longer from now the better. Because, we are paying for finite
  end tests to determine display life. And we hope no news for some time
  because the longer the test proceeds the better the results will be! We
have
  conducted Xenon Arc testing of both inksets and are confident that the
  PiezoTones offer unprecedented longevity. We are offering an ink which we
  believe is both archival and has the greatest possible longevity. It just
so
  happens that our inks have aesthetic qualities which are also
unparalleled,
  but this is a result of our personal convictions. That they are more
trouble
  free, is a result of listening to our customers and responding in a
  responsible way.


  If you are happy with your original inks, you will continue to be.
However,
  ConeTech and ConeEditions and ConeStudio are not known for resting on
  laurels. We have developed some pretty startling mono systems over the
  years
  and Piezographers deserved to be treated to the best ink technology
  currently available so that all Piezographers will have the best chance
and
  opportunity of trouble-free ink delivery. The aesthetics and new stability
  are just some additional icing on what is widely perceived as a pretty
nice
  piece of cake!
