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. Unneeded zones are turned off to reduce cost of power and conserve energy. 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 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.

A rotary beam has mounted thereon a pair of carrier arms for rotatably supporting a roll of web from which the web is fed into the press, and another such arm pair for supporting another such web roll to which the web is to be spliced upon consumption of the first web roll. One of each pair of carrier arms has rotatably mounted thereto a hollow spindle to be partly inserted in the tubular core of the web roll. The hollow spindle has detents arranged at circumferential spacings thereon for fluid pressure actuation into frictional engagement with the inside surface of the web roll core. The other of each carrier arm pair has a second spindle rotatably mounted thereto which is to be held endwise against the web roll core via a spring-loaded end cap. How hard the web roll core is urged against the first spindle by the second spindle, resisting the unwinding of the web therefrom, depends upon whether the second spindle is held fast against the end cap or spaced therefrom by the spring. The second spindle is sprung away from the end cap upon decrease of the web roll diameter to a predefined limit, in order to mitigate tension on the web being paid out.

The gel method of printing variable information of the present invention involves applying inks onto a substrate that is part of or attached to a cylinder of the printing machine. Imaging is by means of an energy source in the UV, visible or infrared regions, modulated to represent a digital image pattern that has been composed on a computer. The consequence of imaging is to gel the ink and increase its adhesion to the substrate of the printing cylinder. The non-gelled background ink with lower adhesion is then removed by a squeegee action and returned to an ink reservoir. The remaining image is transferred to an offset blanket or directly to print stock by pressure. The process does not use a master, but produces an image that is erased after printing with each cylinder rotation so that the next rotation producing the next print can have fresh information written upon it.
