A rotary printing press has a folding station where the printed web is perforated both transversely and longitudinally in order to expedite subsequent folding thereof into signatures. In order to incorporate a longitudinal perforator into the folding station without adding to its size, a longitudinally perforating blade similar to a circular saw is mounted to a blade carrier shaft which is rotatably supported opposite a feed roller by which the web is frictionally fed into and through the folding station. An annular, longitudinally grooved anvil is formed circumferentially on the feed roller for engaging the longitudinally perforating blade via the web being thereby perforated. The longitudinally perforating blade is movable with the blade carrier shaft into and out of perforating engagement with the anvil on the feed roller.

The present invention relates to a method and a system for online creation and ordering of customized material for printing, where each customer at front end, through a computerized interface, participates in the process of creating, editing, proof printing and finally ordering print-ready files through Internet, via a printing service provider which automates the production of the print-ready files, and where print shops carefully chosen by the printing service provider automatically receives the print-ready files directly into their printing press. A PDF engine uses two XML files to create a customer PDF document for printing on demand. One XML file, the data XML file, comprises the data and it's typing for printing, and is created by the customer through the computerized interface. The second XML file, design XML file, comprises a description of how said data can be positioned and formatted, in a created document by the customer through said interface. The PDF engine generates the print-ready document through providing a new structure by analyzing the two XML files, while analyzing merging data and formatting information, thus making it possible to create a PDF document with a distinct difference between data to be printed and the design of the PDF document.

A first customer provides a CAD file defining the surface profile for a part to be molded to the system, and a second customer does the same for a second part. The system determines whether the materials match and the run dates overlap, thereby qualifying the parts for use in a multi-customer mold block. The system assesses the part surface profile (which could have any of a virtually infinite number of shapes) of the parts submitted and lays out the parts from multiple customers on one or more multi-customer mold blocks. Savings are generated, such as by reducing redundancies in press clean-up, in set-up, in tooling, and in surface finishing. Due to these savings, the system provides a quotation of the part to at least one of the customers which differs from the quotation that would be provided if each part was run independent of parts of other customers.

A computer controlled power saving automatic zoned dryer for a printing press has a dryer head facing the substrate travel path, having a multiplicity of IR lamps connected individually or in groups to form a plurality of heating zones running longitudinally and each extending laterally side by side across the substrate travel path. The radiant heat output of each heating zone is controlled separately by means of a control unit connected to a power supply. The control unit individually regulates output of the heating zones.

A plurality of heat sensors spaced laterally across the substrate path measure the surface temperature of substrate heated areas corresponding to the heating zones being operated and maintain an automatic set point temperature. The temperature of each individual heated area can be regulated automatically by adjusting the output of its heating zone whereby printed substrates having a more even temperature profile are delivered. In an alternate manual mode any zone can be set independently to operate at any percentage of full available power from zero to 100%. Separate high velocity air scrubbers and additional air extraction are used to enhance the total drying effect of the zoned dryer assembly.

A system, method, and process that determine and automatically correct registration errors between printed objects and mechanically produced objects using advanced image processing techniques is disclosed. Means are also presented for maintaining all registered functions to within very close tolerances during normal running, with other means for rapidly obtaining initial registration with substantial savings in material waste. The disclosed system and method / process are compatible with the printing and converting industry in which rolls of material are processed by printing a number of colors that require close registration especially in pictorial representation. These roll-fed printing machines are quite versatile and in addition to the printing of any number of colors on both front and back can perform any number of additional operations on the printed web at the same time. Some of these additional operations can be the punching of line holes, scoring, perforation and die cutting all of which impart a specific shape mechanically on the printed web. All of these functions must be initially registered to each other and maintained within close tolerances during normal running conditions. The presently disclosed registration system permits these initial registration procedures to be performed with high accuracy, speed, and across a wide variety of web materials and colors. The system generally applies to any web material (5701) on which register marks (5702) are applied, wherein images of the web are obtained (5703) and image processed (5704) under optional control of an operator interface display (5705), resulting in web press motor control (5706) to affect improved print registration on the web material (5701).

A method for calibrating a digitally controllable printing machine having a permanent printing plate, for which image data has been created in machine-independent format in a pre-press stage. The image data is prepared for the printing process by a data processing device and is fed in adapted form to the printing machine 1. The data processing device uses a profile which corresponds precisely with the current machine condition, for the final data preparation for printing. The profile can be addressed using the correct color-space conversion for the printing machine (i.e., calibrated). For this purpose, at the time at which the data is prepared for image setting, a machine condition forecast for the time of printing is called up and, from this, together with the knowledge of the operating materials, the machine profile which most closely approaches that for the print job is determined. This profile is then used for the data preparation.
