Abstract:
1. A method for drying printed material, the method comprising the following steps: driving a one-dimensional or two-dimensional array of 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 in a first step; converting the image data of lower resolution in a second step into data with a resolution reduced once more being matched to a grid of the radiation source array; obtaining position data describing a position of the printed image in a transport direction from a device for transporting the printing material; generating control data for modulation of an intensity of the radiation sources or groups of radiation sources of the array from the image data of lower resolution and position data; and sweeping over printing material in a transport direction with time-modulated radiation points each including a plurality of image points of a higher-resolution printed image.
