A printing plate suitable for retaining ink in an imagewise fashion on a main surface thereof defines an array of pixel-sized cavities. Each cavity has associated therewith a quantity of a light-induced shape-memory polymer. When a cavity is exposed with energy, such as from an imaging laser, the quantity of polymer changes shape and/or position, thereby allowing a relatively greater quantity of ink to be retained in the cavity. The printing plate is then inked, to from a transferable image. The apparatus as a whole enables a gravure-like printing plate to be repeatedly imaged using digital image data.
