Treating paper for tropics

I have to send some platinum prints from the North (West Yorkshire - UK) to a customer in Singapore. The prints are on Bergger COT320 paper. Does anybody have any recommendations regarding anti-mould treatment?

Thanks

Simon

You could best try asking the paper manufacturer? With a platinum print, it would be the paper which was potentially damaged by environmental factors rather than the image itself - or so we keep reading for platinum. I may very well have misunderstood what goes in to the image-forming part of the print though.

A mention in the alternative processes sub-forum might be handy too.
