The ability of a paper to perform on the press. Among the characteristics are: it must be lint-free, accurately trimmed, a moisture content in equilibrium with the relative humidity of the press room, free of curl or wavy edges.
The ease with which a paper moves through a printing press. For example, offset lithography puts more stress on paper than other printing processes because of: how the paper moves through the press; the great amount of water used in the process; and the tackiness of the inks that are used. In order to have good runnability, paper for offset printing must be strong, have great tear resistance, and possess good dimensional stability. It must also be water resistant and have a strong surface so the paper doesn't pick. Runnability is also a term for measuring the number of mechanical web breaks per 1,000 rolls of paper run on a press.
