pt/pd mounting



I've heard a myth I'm looking to bust or confirm, and I figured this would
be a good place to find out.

Someone once told me (can't remember who or where or when) that since
pt/pd is an acidic process that mounting a print in pH neutral or acid
free mat board will actually shorten the life of the print.

So my question is, within the context of pt/pd, how important is the pH
level of mat board for archival mounting?

Thanks,
