Abstract (en)

[origin: CN114379225A] The invention relates to a method for operating a flexographic printing machine having an impression cylinder (16, 105) or a flexographic impression cylinder and a counter-pressure cylinder (17, 106), which support a sleeve (3, 105a) having at least one flexographic stamp (5, 108), and the pressing pressure between the impression cylinder or the flexographic impression cylinder and the counter-pressing cylinder is adjusted through a motor. The setting is carried out automatically as a function of a dot density (303, 304) of the flexographic printing die, i.e. A location-dependent density of the printing protrusions of the flexographic printing die, or data derived therefrom by means of a computational technique. The invention advantageously allows cost-effective and high-quality printing in industrial flexographic printing. In addition, the method according to the invention allows further automated printing in an advantageous manner.
