摘要:
Disclosed herein is a method for flexographically printing over a textured surface. The method comprises selecting a substrate for application of a print pattern and advancing the substrate through a flexographic coil paint line in order to apply a primer to at least one side of the substrate. Next a finish coat is flexographically applied to the primed substrate and due to a chemical reaction of the applied finish coat along with supplemental heating, the finish coat forms a textured surface. Next, a print pattern is flexographically applied atop the textured surface.

Systems and methods for aligning preprinted images on a roll of substrate to the moving components of a web press are disclosed. A method in accordance with one embodiment includes determining the speed of the moving components of the press, determining the speed of the web of preprinted images and adjusting the speed of the web of preprinted image to match the speed of the web. In particular embodiments, a press which produces rolls of preprinted material can be modified to change the equivalent cutoff length of the press. In further embodiments, a method of pasting new rolls of material to expiring rolls of material is accomplished by modulating the drive speed of the new roll of material to match the expiring roll of material while at the same time aligning the images on the new roll with the expiring roll.

A method of controlling a digital printing system that uses multiple metadata packets is provided. A controller including a metadata channel is provided. Information in a first metadata packet that is associated with an initial point of interest of a media is provided by a primary metadata packet creation unit. The first metadata packet is inserted into the metadata channel of the controller. A second metadata packet including new information associated with a new point of interest of the media is created using a secondary metadata creation unit. The second metadata packet with the new formation is inserted into the metadata channel of the controller based on the location of the new point of interest of the media.

A superstructure of a printing press includes a turning tower with at least one turner bar that is usable to deflect a web section from a transport direction by 90°. A second turner bar, that is shorter than the first turner bar, is also used to deflect a web section from the transport direction by 90° in the same direction as the first web section. These first and second turner bars are offset vertically in relation to one another in the same turning tower. The first turner bar is supported at both ends on at least one first lateral support and at least one second lateral support. The second turner bar is supported only on one end on the lateral support in a floating manner. The second support side of the second turner bar is provided with access from that support side into the interior of the turning tower.

A printing unit is comprised at least of a plurality of printing machines which are arranged on the same side of a web to be printed. Each such printing machine includes an inking unit having at least one roller, and a dampening unit. Rollers of the inking units of several of the printing machines, which are arrayed on the same side of the web to be printed, are in thermal contact with the same temperature-control medium unit for controlling the temperature of the rollers. The temperature control medium circuit is configured as an inner temperature-control medium circuit having substantially constant circulating volumetric flow rate of a temperature-control medium.
摘要:
A printing unit for printing a web of paper is provided. The printing unit includes a frame and an upper printing group and a lower printing group. The printing unit has at least one throw-on configuration and a blanket-changing throw-off configuration. The blanket cylinders are capable of each receiving at least one tubular blanket. The frame has, in at least one lateral wall, at least one opening to allow the passage of the tubular blankets. In the blanket-changing throw-off configuration, the blanket cylinder of the upper printing group has been moved upwards relative to the position which it occupies in the throw-on configuration and the blanket cylinder of the lower printing group has been moved downwards relative to the position which it occupies in the throw-on configuration, so that an adequate space is provided between the blanket cylinders to allow a web of paper printed by another printing unit to pass between them.

An offset web print unit includes a plate cylinder, a blanket cylinder, the plate cylinder being movable during a throw-off operation, and a tucker bar for tucking plates into the plate cylinder, the tucker bar having an axis movable with respect to the plate cylinder axis for reducing a gap during the throw-off operation.

A printing unit for printing a web of paper is provided. The printing unit includes a frame and at least an upper printing group and a lower printing group, each printing group including a blanket cylinder and a plate cylinder. The printing unit also including a cylinder support and movement and having at least one throw-on configuration in which the blanket cylinders are pressed against each other and against the plate cylinders, and at least one throw-off configuration in which the blanket cylinders are spaced apart from each other. In the throw-off configuration, the upper blanket cylinder has been raised by a first height relative to the position which it occupies in a throw-on configuration, and the lower blanket cylinder has been lowered by a second height relative to the position which it occupies in a throw-on configuration, and the second height is different from the first height.
