Re: [BKARTS] deacidification of color newsprint



I do know that different newspaper printers use different ink.  The San
Francisco Chronicle changed to water-based ink some years ago.  There had
been plenty of complaints of the ink rubbing off--black hands, grimy
upholstery, etc.  Probably it was also a financial decision.  Those problems
are gone, but because the water-based ink doesn't "adhere" to the press
rollers as well as oil-based inks, there are frequent verticle folds in the
pages.  The publisher told us that it can't be avoided.

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.
