Abstract

A method for drying printed material operates with the aid of a one-dimensional or two-dimensional array of radiation sources which can be driven individually or in groups. At the same time, the high-resolution image data describing the printing image or a content of printing forms for individual color separations is transformed into image data of lower resolution. Position data which describes the position of the printed image in the transport direction is also obtained from a device for transporting the printing material. Control data for modulation of an intensity of the radiation sources or groups of radiation sources of the array are generated from the image data of lower resolution and the position data, so that the printing material is swept over in the transport direction with time-modulated radiation points which in each case include a plurality of image points of the higher-resolution printed image.
