摘要： A method for transferring an image to a medium includes: generating a substantially uniform line of radiation; producing diffractive light from the uniform line of radiation; passing zero order diffractive light to the medium in a telecentric fashion while blocking non-zero order diffractive light; adjusting image magnification on the medium independent of image focus in response to the zero order diffractive light; and adjusting image focus on the medium independent of image magnification in response to the zero order magnification-adjusted diffractive light. An optical imaging head for transferring an image onto a medium via the above method includes: a line illumination module for generating a substantially uniform line of radiation; a grating light valve which receives the line of radiation and generates diffractive orders of modulated radiation; a first lens group for adjusting image magnification independent of image focus; a second lens group for passing radiation to the medium in a telecentric fashion, the second lens group adjusting image focus independent of image magnification; and a stop, placed between the first and second lens groups, having a single aperture for passing zero order radiation and blocking non-zero order radiation.

摘要： An autofocus process for imaging optics of a scanner comprises performing multiple scan-line image captures of the document to be scanned. In the preferred embodiment, these captures are of essentially the same scan-line. A focal position of imaging optics, which forms a scan-line image, is adjusted relative to an image detector in between the multiple scan-line captures of image data. In the preferred embodiment, the imaging optics is adjusted. Relay optics or a position of the image detector could alternatively be adjusted. In any case, a focus setting for a subsequent scanning operation is then calculated based on the image data from the multiple scan-line captures. In the preferred embodiment, this calculation yields a lens position for the imaging optics. The invention thus allows autofocusing to the document to be scanned. Problems associated with loss of calibration are avoided. Moreover, the system is able to adapt to documents where the image is not at the scanner's nominal focal plane.

摘要： A lithographic printing plate precursor is disclosed which comprises (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer and (ii) a coating provided thereon, the coating comprising an oleophilic layer which, upon image-wise exposure to heat or infrared light and subsequent immersion in an aqueous alkaline developer, dissolves in the developer at a higher dissolution rate in exposed areas than in unexposed areas, wherein the oleophilic layer comprises a polymer that is soluble in the developer and an organic dye in a amount sufficient to provide a visible color to the coating, characterized in that said organic dye does not reduce the dissolution rate of the unexposed areas in the developer. By using non-inhibiting dyes, the sensitivity of the precursor upon image-wise exposure is increased.

摘要： An optical wedge (115) compensates for a vertically drifting laser beam (45A, 45B, 45C) in response to ambient temperature fluctuations. A slit sensor (75) is formed onto a surface (155) of the wedge to separate a single light pulse (100d) from a plurality of light pulses (100a...e). A reflective filter layer (140) is applied to a side opposite the slit sensor (75) so an incident laser beam (45A, 45B, 45C) is attenuated thereby precluding damage to the slit sensor (75). The reflective filter coating (140) further filters out unwanted light energy. The wedge (115) is shaped so as to maintain a position of a focal point (60A, 60B, 60C) of a laser beam (45A, 45B, 45C) on the slit sensor (75) and to prevent reflected light (80) from damaging a laser source (40).

摘要： A media receiving cassette is disclosed for use in a system in which a web of media is transferred from a supply cassette to the receiving cassette. The media receiving cassette includes a housing, a rotatable core, and a spring biased grasping mechanism. The housing includes first and second opposing ends, and at least one of the ends includes a generally circular track therein that includes an extended portion which extends radially outwardly. The rotatable core is coupled to the first and second opposing ends of the housing such that an axis of rotation of the core extends through each of the first and second ends. The spring biased grasping mechanism is attached to the rotatable core via at least one spring. The grasping mechanism includes a tracking member that engages the generally circular track such that the grasping mechanism is permitted to move radially outwardly away from the core when the tracking member is positioned in the extended portion of the generally circular track to thereby permit the media to be received in the core. The grasping mechanism is permitted to move radially inwardly toward the core when the tracking member is positioned in a location other than in the extended portion of the generally circular track.

摘要： The method reproduces an electronic image, having pixels, as a multilevel halftone image on a multilevel output device having N different allowed output values (possible density levels) by

choosing for any pixel p a real subset S p containing N p allowed values out of the set S of N allowed levels
quantizing the input pixel value of the pixel p to obtain an output pixel value out of the N p values in S p by means of a halftoning algorithm,
rendering the image by rendering the pixels with the output device using the obtained output pixel values.

The real subset may be formed by the allowed output values closest to the input pixel value.
The quantization may be done by an error diffusion algorithm The used method prevents occurrence of pixels having deviating densities distorting the output image.
