Abstract: The present invention generally relates to a method (34) for controlling a drying procedure of a printed product and an industrial printing machine (10). The printed product is manufactured by the industrial printing machine (10). An image to be printed is split into several image cells. For each image cell a total amount of ink to be used and an average lightness value of the ink to be printed within the respective image cell are determined. For each image cell a cell-dependent amount of infrared radiation to be applied for drying the ink to be used within the respective image cell is determined based on the total amount of ink to be used and the average lightness value determined in view of the respective image cell. A mixture of the drying procedure to be applied for drying the ink to be used within the image to be printed is determined based at least on the cell-dependent amounts of infrared radiation to be applied and a moving speed of the printed product. The mixture comprises at least a ratio of an overall amount of infrared radiation and an overall amount of convective heating.

Abstract: A clamping device (18) for supporting a reel having a tubular core is described. The clamping device (18) comprises a base body (20) with a mounting interface (22) for fixing the base body (20) on a machine frame. Additionally, it has a carrier body (36) configured for being placed inside the tubular core of the reel. The carrier body (36) is rotatably supported on the base body (20) such that the carrier body (36) can rotate with respect to the base body (20) about an axis (38) of rotation. Moreover, a plurality of clamping elements (42) are coupled with an actuation mechanism (76) such that the clamping elements (42) can selectively protrude from an outer circumference of the carrier body (36) and selectively be retracted to be at least flush with the outer circumference of the carrier body (36). Furthermore, a brake mechanism is arranged between the base body (20) and the carrier body (36) for selectively decelerating or blocking the rotation of the carrier body (36) with respect to the base body (20).

Abstract: A method for aligning printing heads (12) of a printing device is provided, the printing heads (12) being two-dimensional printing heads (12) comprising a plurality of nozzles (30). In one method step, an ink drop is dispensed at a plurality of nozzles (30) of every printing head (12) simultaneously to print an image, preferably at all nozzles (30) of every printing head (12). In another step, the printed image is captured by a camera (20) whose resolution may be smaller than the print resolution. The position and/or orientation of each of the printing heads (12) is determined based on the image captured by the camera (20) and the deviation of the position and/or orientation of each printing head (12) from a target position and/or orientation is determined. The position and/or the orientation of the printing heads (12) is adjusted based on the determined deviation. Moreover, a printing device (10) is provided.
