A laser system comprising high voltage AC-to-DC power converter and one or more current sources coupled to the high voltage AC-to-DC power converter without a DC-to-DC converter between the one or more current sources and the AC-to-DC power source. Each of the one or more current sources includes a high voltage switch and one or more independent safety shutoffs. A laser module is operably coupled to the one or more current source and configured to emit electromagnetic radiation wherein the one or more safety shutoffs are configured to disable emission of electromagnetic radiation from the laser module when triggered.

A mirror is disclosed for use in a limited rotation motor system, wherein the mirror includes a body, an aperture within the body, and a high density material within the aperture. The body, formed of one or more materials, has an exposed mirror surface and is mountable with the limited rotation motor system for rotation with respect to an axis of mirror rotation. The aperture is positioned at least proximate to a portion of the axis of mirror rotation. The high density material is provided within the aperture such that it is capable of movement within the aperture, and the high density material has a density that is greater than a density of the material of the body of the mirror.

Systems and methods of providing improved performance of scanning mirrors coupled to limited rotation motors

A position transducer system is disclosed for a limited rotation motor that includes an illumination source that directs illumination toward an illumination reflector that rotates with a rotor of the limited rotation motor, and a plurality of detector areas adjacent the illumination source for receiving modulated reflected illumination from the illumination reflector.

A laser processing system is disclosed for providing a relatively small velocity of a laser beam at target location while at least one scanner scans at a relatively larger velocity. The system includes a laser source, a first scanning unit, a beam expander, a second scanning unit and focusing optics. The laser source is for providing a pulsed laser output having at least one beam with a beam dimension. The first scanning unit is for scanning the laser output in a first direction along a first axis at the target location. The beam expander is for receiving the laser output and for modifying a beam diameter of the laser output and providing a modified laser output. The second scanning unit is for scanning the modified laser output from the beam expander in a second direction along the first axis at the target location. The second direction is substantially opposite to the first direction along the first axis such that a net velocity of the modified laser output along the first axis at the target location may be made to be effectively zero during a laser pulse. The focusing optics is for focusing the modified laser output toward the target location.

Disclosed is a jet printing method, which includes firing printing fluid drops and deflecting them. The drops are then deflected again in a second direction, which can allow them to be deposited in a collimated swath. Also disclosed is dynamically adjusting the deflection to achieve a dynamic swath density and/or a dynamic swath width.

Jet printer with enhanced print drop delivery

A proof generation method is disclosed for proof printers. The method includes receiving halftoned primary color print data to be printed on a target halftone printing press. This halftoned primary color print data has been produced by a first halftoning technique, and is at least comparable to a target halftoning technique used by the target halftone printing press. A second, different halftoning technique is also applied to the print data. The two halftoning techniques are selected to cause a dot size in data provided to the proofing printer to more closely match a dot size for the halftone printing press, and cause a proof produced by the proofing printer to substantially match the color of a print produced by the target halftone printing press.

Print proofing with color and screen matching

A certified proofing method is disclosed that includes receiving a printable sheet and automatically detecting at least one feature of at least one component of a proofing process bearing on its quality. The method also includes automatically evaluating at least one result of the step of detecting, printing print data on the printable sheet, and generating a certification notice for the printable sheet in response to a positive electromagnetic result signal from the step of evaluating.

Disclosed is a continuous ink jet printer that includes an ink jet printing nozzle for a first color positioned to deposit ink drops on a substrate, and a deflection element located proximate an output trajectory of the first ink jet printing nozzle and operative to deflect the ink drops in a swathed pattern as they are deposited on the substrate by the first ink jet printing nozzle. A second ink jet printing nozzle is also provided for the first color positioned to deposit ink drops on the substrate, and a second deflection element is located proximate an output trajectory of the second ink jet printing nozzle and operative to deflect the ink drops in a swathed pattern as they are deposited on the substrate by the second ink jet printing nozzle. Interleaving logic is operative to provide interleaved print data to interleave at least one deflected drop from the first ink jet printing nozzle with a plurality of deflected drops from the second ink jet printing nozzle in parallel offset rasters.

One general aspect of the invention provides for creating half-tone ink-jet proofs on print-enhanced sheets based on an effective image cell pitch that substantially matches a cell pitch used to create press plates. Print process variables can be adjusted for the ink-jet proofing printer based on received color matching information. These adjustments can define preprint ink mixing ratios that allow at least some image cells to be printed with ink mixtures. Or they can define sub-area printing values that allow at least some dots to be printed with areas of different inks.

A printing fluid delivery method is disclosed for a jet printer. The method involves displacing printing fluid in a printing fluid delivery chamber in a printing fluid delivery system by a predetermined amount. After the step of displacing, printing fluid can be driven out of the chamber at a constant flow rate.

A set of ink-jet printable proofing sheets are disclosed that each comprise a first printable face having a periphery including first, second, third, and fourth edges. The first and third edges are disposed opposite each other on the first printable face, and the second and fourth edges are disposed opposite each other on the first printable face. The first face has properties resulting from a deposited ink drop print-enhancing treatment. Each sheet also includes a second face sharing the periphery and the first, second, third, and fourth edges of the first printable face, and a first machine-readable mark located on one of the first and second faces and including a plurality of data areas of different densities, with the combination of densities in the data areas being unique to each sheet.

A jet printer is disclosed that includes a print head attached to a movable carriage, with a deflection element having a deflection axis in the direction of an axis of rotation of a drum. A carriage mechanism can move the carriage in the direction of the axis of rotation of the drum. The printer also includes self-interleaving logic with an output provided to the print head, as well as a control circuit responsive to a swathing table and having an output provided to the deflection element.

Interleaved printing

A method of jet printing is disclosed in which a jet printing fluid source advances in a helical progression with respect to a drum, and drops from the jet printing fluid source are guided to a substrate in steps that define a swathing order that separates their trajectories. A printing system is also disclosed in which a digital filtering function is applied to a desired input position value to obtain a guiding value for a drop of printing fluid.
