    摘要: The disclosed embodiments include a method to compensate for defective printer nozzles included in printer nozzles used to print an image on a medium. The method includes detecting defective printer nozzles, and initiating a print job in a print mode. The print job can include image data used to print the image on the medium in accordance with a print mask that maps the printer nozzles to pixel locations of the image. The method further includes modifying the print mask or the image data to print using the image data with printer nozzles that may be complementary to the defective printer nozzles, and printing the image on the medium in accordance with the print mode and the modified print mask or the modified image data.

    摘要: A single-pass imaging system (100) utilizes a light source (110), a spatial light modulator (120) and an anamorphic optical system (130) to form a substantially one-dimensional high intensity line image on an imaging surface (e.g., the surface of a drum cylinder). The light source (110) and the spatial light modulator (120) are used to generate a relatively low intensity two-dimensional modulated light field in accordance with an image data line such that each pixel image of the line is elongated in the process (Y-axis) direction. The anamorphic optical system (130) utilizes a cylindrical/acylindrical optical element to anamorphically image and concentrate the modulated light field in the process direction to form the substantially one-dimensional high intensity line image. The line image is generated with sufficient energy to evaporate fountain solution from the imaging surface. The imaging system simultaneously generates all component pixel images of the line image, thus facilitating a printing apparatus capable of 1200 dpi or greater.

    摘要: A light from a laser light source (11) is collected at a position of a slit (125a) in a vertical direction by a first optical system (12a) to form an intermediate image which is long in a horizontal direction corresponding to an arrangement direction of light modulator elements. An undesired light such as side lobes which appear on the both sides of the intermediate image in the vertical direction is blocked by a slit (125a) and the intermediate image is reformed by a second optical system (12b), to direct a liner illumination light onto the spatial light modulator (13). Thus, in a state where moving ribbons are sagged and first order diffracted lights are emitted in a light modulator element, it is possible to prevent a zeroth order light from being emitted from both end portions of ribbons, to thereby enhance contrast of the signal light.

    摘要: Device (10) to effect micro-displacements of a support for digital images (11), in which the digital images are formed by a determinate matrix of pixels (37) arranged in lines and columns perpendicular to each other. Each pixel (37) has a determinate lateral size (l) and between adjacent pixels (37) there is a free space having a determinate amplitude (s). The device (10) comprises a fixed structure (39) having an optical axis (Z), support members (38) that keep the support for digital images (11) on a plane orthogonal to the optical axis (Z), and actuator members (40, 41, 42, 43) arranged between the fixed structure (39) and the support for digital images (11), in order to displace the support for digital images (11), along the plane and in the directions (X, Y) of the lines and columns, with respect to the optical axis (Z). The actuator members (40, 41, 42, 43) are associated with electronic control elements (31) and effect one or more unitary displacements, in the directions (X, Y), each one equal to or less than the determinate amplitude (s) of the free space between adjacent pixels (37).

    摘要: The invention provides an improved illumination system for use in imaging systems that may produce a non-overlapped near field image (34) in the slow axis direction, and a far field image (15) of the illumination source (20) in the slow axis direction at a light modulator (14). In an embodiment, the illumination system produces an area of illumination for a light modulator (14) along a slow axis direction and along a fast axis direction, and includes a plurality of laser diode emitters (20), a first array (24) of first micro lenses, and a second array (26) of second micro lenses. The plurality of laser diode emitters (20) are arranged in an array, and each of the laser diode emitters produces illumination in a slow axis direction and in a fast axis direction. Each first micro lens in the first array (24) corresponds to one of the laser diode emitters (20), and collimates illumination in the slow axis direction. Each of the second micro lenses of the second array (26) corresponds to one of the first micro lenses (24). Each of the second micro lenses (26) is arranged to receive illumination from one of the first micro lenses (24). The first micro lenses produce a non-overlapped near field image (34) in the slow axis direction.

    摘要: Für die Herstellung eines fotografischen Bilds von einer in elektronischer Form vorliegenden Vorlage werden mittels eines elektrooptischen, pixelweise arbeitenden Wandlerorgans (3) nacheinander von wechselnden streifenförmigen Abschnitten der Vorlage optische Darstellungen (D) erzeugt und diese optischen Darstellungen (D) in einem streifenförmigen Belichtungsbereich (E) auf das Kopiermaterial (P) abgebildet, wobei der streifenförmige Belichtungsbereich (E) und das Kopiermaterial (P) im wesentlichen mit konstanter Geschwindigkeit in Richtung quer zur Längserstreckung des streifenförmigen Belichtungsbereichs (E) relativ zu einander bewegt werden, so dass sukzessive die Bildinformation der ganzen Vorlage auf die gesamte zur Verfügung stehende Fläche des Kopiermaterials (P) aufbelichtet wird. Das elektrooptische Wandlerorgan (3) ist so im Abbildungsstrahlengang angeordnet, dass seine Zeilen und Spalten zur Längserstreckung des streifenförmigen Belichtungsbereichs (E) im wesentlichen um 45° geneigt verlaufen. Dabei wird zur Erzeugung der optischen Darstellungen (D) der streifenförmigen Abschnitte (A) der Vorlage (V) ein streifenförmiger, im wesentlichen in einer Diagonale des Wandlerorgans (3) liegender Pixelbereich des letzteren verwendet. Als elektrooptisches Wandlerorgan (3) wird vorzugsweise ein digitales Mikrospiegelfeld eingesetzt.
    Durch die gedrehte Anordnung des Wandlerorgans wird eine gegenüber klassischen Anordnungen höhere Auflösung erreicht, so dass sich mit relativ geringem konstruktiven Aufwand unter Einsatz von handelsüblichen Wandlerorganen auch grossformatige fotografische Bilder mit hoher Qualität herstellen lassen.
