is mdf board acidic and harmful to block mounted photographs?

Question

i want to know if there is a long life span with block mounted photographs. I've had one person say mdf is acidic and photos fade in colour eventually and a block mounter has told me that the lamination process eliminates the harmful effect of the mdf.

Answer 1

I hate to spoil things but in addition to MDF board not being arhivally sound, the lamination process is almost certainly not an archivally sound. However, as long as you are not selling these photos and putting your reputation at stake, and as long as you have the original negatives or files, then don't worry, it will probably take some time for the images to degrade to the point where you need to reprint.
