1. A method for drying printed material, the method comprising the following steps: driving a one dimensional or two dimensional array of UV radiation sources individually or in groups for drying the printed material; transforming high resolution image data, describing a printing image or a content of printing forms for individual color separations, into image data of lower resolution matched to a grid of the UV radiation source array; obtaining position data describing a position of the printed image in a transport direction from a device for transporting the printed material; generating control data for modulation of an intensity of the UV radiation sources or group of UV radiation sources of the array from the image data of lower resolution and position data; and irradiating the printing material with time modulated UV radiation points each including a plurality of image points of a higher resolution printed image.
