Abstract: A print screen tonal control and compensation system and method are provided in which a compensated density curve is utilized to increase press predictability, performance, resources consumption, color variation, and quality. A computerized test pattern is generated, and by applying computer to plate technology, a printed press produces a printed test pattern. The test pattern is subsequently analyzed to identify the plugging point of the production run, and a compensated density curve is created to eliminate plugging within the production pattern. The density curve is then used to generate a compensated printing plate for use in a production press run.

Abstract: A system and apparatus for automatically executing process steps by processing devices transmitted, over a communication channel, using a workflow file to specify the process steps. Devices are used to edit, initiate, and observe workflow execution. Editing comprises selecting process steps, executing parameter selection software supplied by the processing device, and drawing links between icons. Once workflow execution is initiated, workflow data is passed from one processing device to the next. Each processing device performs the process step specified by the workflow file with the selected parameters and optionally sends status information to observing devices. This sequence continues until all process steps are executed or an error occurs.

Abstract: A device that determines conditions under which a web break is more likely to occur in a printing system stores data pertaining to ink temperature or ink temperature gain. The device then implements a correlation analysis, such as a decision-tree induction analysis, using the stored data to determine if there is a correlation between the one or more attributes and the occurrence of a web break. The device has a multiplicity of ink fountains and includes a first temperature sensor that measures a first ink temperature and a second temperature that measures a second ink temperature. A controller compares the first ink temperature to the second ink temperature to determine an ink temperature gain, compares the ink temperature gain to a desired ink temperature gain range and generates an output signal based on the comparison.

Abstract: A compact disc storage book is formed with board book pages having pockets therein to receive compact discs. The board book is comprised of folded, printed signatures adhered to one another. A hard cover is attached to and covers the pages to protect the pages and compact discs from damage or contamination. The board book has an expandable spine, which increases its size or thickness from its smaller empty size to its larger, filled size when filled with compact discs. In the preferred method of making this storage book, the signatures have been printed and slit to form the CD receiving pockets prior to being folded on a signature folding machine. The folded signatures are fed by feeders of a signature gathering machine in proper sequence onto a gathering conveyor. The signature gathering machine has a programmable glue applicator to form the glue pattern including the glue pattern for the accordion fold, expandable backbone for the book form.

A database is developed having a number of entries, each of which represents variable printed information and an electronic press is responsive to the sets of template data and the database to print the first and second template pages with selected variable printed information.

Abstract: A folded paper board compact disc carrier for carrying a plurality of compact discs. A compact disc carrier formed from a single piece of stock comprises a paper board blank having a central portion divided by a fold line into first and second planar portions. Each portion includes a side edge having a tab and a pair of opposing flaps foldable along a fold line lying perpendicular to the central portion fold line. Each flap is foldable to an inward position wherein the flaps define with their corresponding planar half an enclosure adapted to receive a compact disc. Upon folding the first and second planar portions along the central portion told line the enclosures are placed in spaced apart parallel relationship with the side edge tabs of each planar half disposed adjacent each other. The compact disc carrier so formed requires no glue or other adhesives and will hold a plurality of compact discs.

Abstract: A new and improved grease shunt valve and lubrication system for a printing press or the like is achieved by the adding of vent drains and/or seals to prevent the accumulation of a waxy-like residue from the grease that interfered with operation of a return spring for closing of the valve. An existing solenoid, operated, grease shunt valve may be retrofitted with an additional body portion having a grease drain vent therein and a seal that seals grease from flowing along a solenoid, actuating rod and into the solenoid core. Preferably, an end plug that seals one end of the return spring is drilled to provide the drain vent for grease flowing into the spring chamber. Vent holes may also be drilled into the solenoid housing to drain and vent grease flowing into the solenoid core.

Abstract: This invention concentrates on relieving the ergonomic strain on a bindery line operator by always loading at an ergonomically correct height for minimum wrist strain and also performing the “jogging,” which is normally done by the operator prior to placing a stack onto the pocket feeder. The signatures are placed onto a lift at the same height because the signature stack support is being lowered automatically until the pivoted conveyor is full. Then, the entire log is pivoted upwardly and advanced to meet the rear of the previously loaded log. The log is advanced through a series of air blasts to aerate the signatures, a vibrating table to align the backbones, and a set of oscillating guides to align the signatures head to foot to eliminate the manual jogging of signatures and thereby repetitive movement of the operator's wrist to do the jogging.

Abstract: In order to be able to eliminate a mechanical caliper, a bindery line has a plurality of signature feeders or packer boxes each of which is operable to feed a signature therefrom. A collating conveyor passes by each of the signature feeders or packer boxes along a signature conveying path so as to be operable to receive signatures from the signature feeders or packer boxes in collated form for forming a book. A book finishing section is downstream of the signature feeders or packer boxes for forming the book from the signatures received in collated order after the collating conveyor has passed by each of the signature feeders or packer boxes in travel along the signature conveying path. With this arrangement, the invention utilizes detectors for detecting a missing signature, an incorrect signature, a double signature, a conveyor jam, a hanging book, and a long book.
