-------------------------------------------------------------------------------------------------- Subject: [Consdistlist] How do I care for aluminum offset print plates
...We recently came upon some plates from 1960s publications that appear to be aluminum offset printing plates. How should I be storing these. They seem in good condition and are now being stored in flat map folders in a room that is kept at 60 degrees and 50-55% humidity. Should I remove them from the folders and store separately or are they save in with paper products?... Marybeth S. F.

Like with like, in this case so you could hopefully store them in a lower humidity level to avoid potential corrosion products, which could stain surrounding items, if you're unsure of the composition of the plates. The map folders themselves are likely fine but what I would be concerned about would be the retrieval of the plates or other items. Depending on how they are stored retrieval could cause the plates to slide around and cause damage. Also, if the plates are thicker the weight of the plates could cause compression damage to items below if they are stored on top of items in your paper storage. In an ideal word I'd likely store them padded in a box but that'd depend on available materials and the characteristics of the plates.
