International Classification:

B65H 502

US Classification:

271276, 271 322, 355 73

Abstract:

A method and apparatus for holding recording media against a media support surface of an imaging system using an arrangement of variable cross-section vacuum grooves. Each vacuum groove has a continuously decreasing cross-section along its length. Each vacuum groove has a maximum cross-section adjacent a vacuum port and a minimum cross-section at a distal end of the vacuum groove.

International Classification:

B41N 300

US Classification:

1014631, 101467, 358 329, 430204, 430302

Abstract:

A method for characterizing exposure levels in a platesetter comprises exposing regions of a plate at different exposure levels by modulating the power of an exposure beam and then analyzing the plate after development to determine a desired exposure level for plates on the platesetter by reference to the regions receiving the different exposure levels. The plates are preferably exposed in an area outside of a printing area. In this way, the exposure test can be performed as part of the normal plate printing process. The plate is not consumed. Moreover, the plate exposure setting can be constantly monitored throughout production in one implementation.

International Classification:

H01R 4/48
H05K 9/00

US Classification:

174369, 174386

Abstract:

The present invention relates to a device package, such as an electronic system package, that is suitable for use in harsh military or commercial environments. The package components, including a base enclosure and mating cover, comprise a series of interconnected electrically conductive materials, forming a tortuous electrically conductive path, that advantageously shield electromagnetic interference (“EMI”). The electrically conductive, EMI-shielding layers and other coated layers (e. g. , insulative electrocoated paint layers) are smooth layers that provide corrosion resistance to the interior and exterior surfaces of the package. The package is also designed such that its components form a water tight seal. Thus, innovatively, the package comprises a combination of components that synergistically shield electromagnetic interference, resist interior and exterior corrosion, and form a water tight seal. The package is configured to pass military specification EMI and salt fog standard testing.

Inventors:

Assignee:

Agfa Corporation - Wilmington MA

International Classification:

B41J023/00

US Classification:

347/037000, 347/105000

Abstract:

An imaging engine for a platesetter comprises an imager for exposing a line of the plate that extends transversely across the plate. The plate is supported on a belt adjacent to the imager. The belt moves the plate to scan the line from the imager laterally across the plate. A vacuum platen is provided under the belt to pull the plate against the belt. The belt is the preferably porous to transfer the vacuum provided by the platen to the plate, to thereby pull the plate against the belt. Variable depth vacuum grooves can be utilized to provide a more constant vacuum across the platen. The belt is preferably supported by a first roller and a second roller that tension the belt under the imager. A detent system is provided to lock the rotation of the rollers to the movement of the belt. In this way, by using a high precision encoder in the drive motor, the belt can be positioned to the resolutions required for high resolution imaging of the plate.

Inventors:

James Hebert - Manchester NH, US

International Classification:

H04N001/04

US Classification:

358/496000, 358/497000

Abstract:

The present invention provides an apparatus and method for incrementally displacing a supply of recording media, such as a printing plate, past a scanning system. The apparatus includes an entrance platen, an exit platen, and a reference platen, movable between a first position adjacent the entrance platen and a second position adjacent the exit platen, for incrementally displacing recording media past the scanning system.

International Classification:

B41J 2325
B41J 2435

US Classification:

347171

Abstract:

The invention involves an internal drum thermal imaging apparatus comprising a support for supporting a receiver material and a donor material in a superimposed relationship. The support includes a cylindrical drum having an inner circumference on which the receiver material is supported against in a bottom layer of the superimposed relationship and the donor material in a top layer of the superimposed relationship. An imaging unit thermally transfers an image from the donor material to the receiver material. An applicator automatically loads and unloads the receiver material and donor material onto the cylindrical drum comprising an applicator carriage, an attachment device for attaching the receiver material to the applicator and an applicator transport device for transporting the applicator carriage along the inner cirumference of the cylindrical drum.
