The material so marked will be removed or excised. demand printing Printing only the amount of material that is needed immediately, rather than printing and storing large quantities from which small quantities are drawn from time to time. Demand printing frequently uses digital printing presses. The higher cost of printing on demand is offset by the savings resulting from eliminated storage and waste costs since large quantities do not need to be stored and out of date stock thrown away.
