Digital BW, The Print

Rightyo.  

I know that chromogenic prints (color photographs and I believe Dye Sub prints) are adversely affected.  

I do not know of any information saying color pigment prints (such as pigment inks) are adversely affected.  My gut tells me that color pigments and calcium carbonate go well together (thinking about Michelangelo's fresco work etc..).  

If anyone does know a source that indicates color pigments and and buffer agents (calcium carbonate) have negatives together,  please post the citation.  

Thanks.

  Beware the interaction of color materials and buffering agents.  Certainly they are frowned upon for color
  photographs, which would superficially indicate that they are bad for dyes.  Don't know about pigments tough.
