ISO 8791-4:2007 specifies a method for determining the roughness of paper and board using an apparatus which complies with the Print-surf method, as defined in ISO 8791-4:2007. It is applicable to all printing papers and boards with which it is possible to form a substantially airtight seal against the guard lands of the measuring head.
