Re: [Digital BW] Buffered mat board and ink jet color shifts?

2002-10-31 by Ken Carney

Steve: All I can contribute is my own experience.  Since I have been using inkjet "seriously" (maybe five whole years now...) I have drymounted the works on rag museum board, with an overmat of same.  I use a floating window mat, so with that and the drymount tissue, the mat board never touches the print.  Anyway, so far, so good.  This is with pigment and dye base inks.  The drymount tissue is Seal Colormount and Kodak.  I have managed to fade some prints, but those were with older Epson inks and papers, and hung in an office with flourescent lights.  No surprises there.

  Subject: [Digital BW] Buffered mat board and ink jet color shifts?


  It is doubtful that I will ever print enough silver
  prints to use up a considerable investment in acid
  free "buffered" mat board. Light Impressions
  - and others - say that the calcium carbonate used
  as a buffer MAY (emphasis is mine) cause color
  shifts with certain materials, including pigment
  based ink jet prints.

  Two questions:

  1 - Can anyone enlighten the group with empirical
  or scientific evidence of buffering causing color
  shifts (or "shades of gray shifts" as the case may
  be)? Should we be concerned? Or is this just being
  anal <VBG>?

  2 - What about dye based inks? Any concerns here?

  Thank you,
  Steve T.
