Though not an official project of the theater, the drama festival has its imprimatur [ˌɪmprəˈmætʃər].

imprimatur
noun [ˌɪmprəˈmætʃər]

Imprimatur is a formal word that refers to explicit approval or permission.

Imprimatur means “let it be printed” in New Latin (the Latin used since the end of the medieval period especially in science). In time, English speakers began using imprimatur in the general sense of “official approval.”
