词源

From one + off. Probably from foundry work, for which making reusable molds is expensive and expediency makes the rule for molds not to be used only once. A term long used by artists who are printmakers and sculptors to indicate a unique print or casting. If using traditional edition numbering, a one-off would be a "1/1", which is said, "one of one" meaning the first print in an edition of one.
