Abstract: The invention relates to a method for verifying a printing plate, specifically a gravure cylinder, for errors in an engraving of the printing plate, comprising the following steps: Generating at least two proofs using a printing plate to be verified, capturing at least one digital image each of the at least two proofs with an image-capturing unit, comparing each of the digital images of the at least two proofs with the engraving template of the printing plate, wherein the comparison comprises the following steps: Detecting deviations between each of the images and the engraving template, and verifying that the detected deviations occur in identical fashion on the digital images of all of the at least two proofs, wherein a pseudo error is indicated if the comparison does not show identical deviations between the digital images of the at least two proofs, and wherein identical deviations indicate an engraving defect in the printing plate.

Abstract: A compact roll arrangement has a device and method for regulating the roll nip so that intermittently coated films may be calendared precisely. A bearing block is arranged in a bearing jewel, and first lever arms of the clamping latch of the upper roll and the lower roll are connected rigidly to one another. Bearing jewels which lie opposite to one another, of the upper roll and the lower roll are connected to one another via a second actuating element. A controller acts on first and second actuating elements, so that the first actuating elements are moved to adjust the roll nip according to a predetermined thrust and a predetermined linear load, and the second actuating elements are moved to maintain the bearing jewels in a relative rest position which is defined by specified densification of a material web passing the roll nip.

Abstract: A roll arrangement having a device for regulating the roll nip, comprising a roll pair which consists of an upper roll and a lower roll, between which a roll nip is formed, wherein each roll is provided with two roll journals which lie axially diametrically opposite one another; at least two bearing blocks for each roll journal, wherein one or more bearings are received in a bearing block; and a bearing block, which lies in each case on the outside on the roll journal, in a clamping latch which has a first lever arm and a second lever arm, wherein the second lever arm of the respective clamping latch of the upper roll and the second lever arm of the respective clamping latch of the lower roll are connected to one another via a first actuating element; mutually corresponding bearing jewels and clamping latches of the upper roll and the lower roll lie opposite one another; and a controller which acts on the first and the second actuating element, is characterized in that the bearing block which lies in each cas
