In a global company using paper SOPS which require SOP signatures from multiple locations, is it acceptable to print PDF copies for evidence of signature and store these as evidence of acceptance or is it required that the wet signatures are stored?

You can add either an electronic signature or a digital signature.
Electronic signatures are cheaper to implement and can only be verified on the 'source' system
Digital signatures require secure certification and have the highest form of security - these are independent of the 'source system'.
Hand written signatures for SOPs may be substituted with electronic signatures - however you must consider whether the integrity, authencity and context of the electronic signature will be maintained through the documents entire retention period ( including archiving ).
Therefore it is recommended digital signatures are embedded into the documents and more appropriate of long term retention.

can be verified.
