I still think there's some confusion here. The issue isn't whether to use an acidic board or to use a non-acidic board; you wouldn't want to use an acidic board under any circumstances. The issue is whether to use (1) a pH neutral, 100% rag museum board (non- buffered), or whether to use (2) a buffered board where the pH is raised to 8 or even 9, to counteract the tendency for the print to become more acidic over time.
