A paper property that measures the extent to which a paper will retain its chemical, structural, and optical properties over time with continued handling (in contrast to permanence, which merely describes a paper's ability to retain its properties over time itself, neglecting the usage aspect). Papers do not necessarily have to be both permanent and durable. (See Paper and Papermaking: Paper Properties.)
The term durability also refers to the extent to which an offset press blanket will retain its thickness, dimensions, and structural integrity over the course of its lifetime, during which it is repeatedly subjected to the increased tension of press mounting and the high pressures of printing. (See Blanket.)
