A term describing the interrelationships of a paper's properties which determine how a paper performs on press. Considerations of a paper's runnability include a variety of structural and surface properties, such as cleanliness of the surface (loose paper fibers cause problems such as piling on the blanket), how well particles of fillers and coatings remain bonded to the paper (loose filler and coating particles can contaminate the chemistry of an offset printing press), how well a paper maintains its dimensional stability (changes in size due to changes in moisture content can affect not only the quality of the printed image, but also cause feeding problems), and other factors such as curling, wavy edges, and chemical composition that have the potential to interfere with the efficient functioning of the printing process. Runnability is usually described in concert with printability, or how well a paper's properties allow a high-quality printed image.
