 French term or phrase: main de Hello, I am baffled by this expression "main de 1,5" in the following, otherwise self-explanatory description of a "beau livre" : Impression quadri pages intérieures sur papier Munken Print White 150g, main de 1,5 Can anyone help? Many thanks in advance.

agree  Tony M: This has come up before and ought to be in the glossary already. I think we do also use the term 'hand' in EN, though I suspect it may now be archaic.

-> Thanks, Tony! I'm afraid I didn't think to check the glossary. Of course, there are an awful lot of entries for "main", as both "hand" and "principal"! // It has come up before, but the glossary entry is wrong. See discussion.

Reference: Main

Reference information:
« Main d'un papier: Le papier peut être souple (il se plie) ou rigide (comme le carton). On peut mesurer le degré de souplesse ou de rigidité du papier grâce à un rapport entre l'épaisseur de la feuille et son grammage. Par exemple, une feuille dont l'épaisseur est de 300 micromètres et qui pèse 200 g/m2 a une "main" de 1,5. C'est un paramètre important pour l'imprimeur qui - par un choix intelligent de papiers de mains différents - peut obtenir des épaisseurs similaires pour des ouvrages qui ont un nombre différent de pages. »
