RE: pt/pd mounting
Well, it took a while, but we finally got some interesting conversation
going. Thanks to those who contributed.
So, to make sure I understand this, here's my take on the topic (please,
correct me if I'm misunderstanding). In theory, pt/pd has enough acid
problems to worry about without using an acid board, so use buffered.
However, there's no proof either way that buffered/neutral pH board
actually increases the life of the print. Right...?
Loris, your polyurethane comment intrigued me. This could add a very nice
aesthetic effect to the series in question, so I may have to give it a
try. I would be very interested to hear the results of your tests if/when
you and Ryuji get around to it. Keep me posted!
