I thought the problem is not the printing ink/toner, but, rather,
the
(chlorine?) bleach used to make the paper white? Book publishers
(especially US) also often identify the paper used as being
'acid-free',
but what about other paper?

I would be surprised if there is any more than a smidgeon of bleach
left in the paper a day or two after it is laid.

Wild picture in my mind there for a minute!
