Invariable curl on Fine Art media

My Fine Art papers have an invariable curl, can I do anything about this as overspray of ink is appearing on the corners?

PermaJet range of papers are manufactured to the highest standards, the curl that appears within the media occurs during the manufacturing process that is inevitable due to the natural mould made process.

To try and overcome this issue the following is recommended, curl the media in the opposite direction of the curl before loading this into your printer.

If the curl is quite invariable than by leaving the media on a heavy weight book or object overnight will flatten the product ready for use.
