Re: [BKARTS] deacidification of color newsprint
One tricky thing (among many) is that some colored
inks are pH indicators.
That is, some colors will change color in response to
a change in pH.
One solution would be to make a color photocopy on
good paper.

Subject: deacidification of color newsprint
What is the best way to deacidify a 2004 newspaper with
a color photo in the article? Is a magnesium-based
deacidifying solution safer than a calcium-based one?
Have there been any studies on long-term color
retention in deacidified newsprint? Have newspaper
inks changed since 2000? Do different newspaper
companies use different inks?
Lots of questions and I would love to start a discussion on this
challenge.
