Printing plates

From: Barry Knight <barry.knight>
Date: Friday, June 9, 2006
The British Library holds a large number of copper and steel
printing plates and steel dies in its collections.  We are naturally
concerned to protect the engraved surfaces from corrosion, and we
have been advised to keep the relative humidity of the steel plates
below 30% to prevent rust.  We have also been advised to protect the
plates by coating them with Japan wax.  Is anybody familiar with
this substance--its ease of application and removal, ageing
properties etc?
