Abstract: The invention relates to a method for printing image material (2), which lies on top of a sheet carrier (1), in an inkjet printer. The inkjet printer comprises an inkjet print head (6), which only partially covers the image material (2). The image material (2) is printed during a temporally successive relative movement, occurring in the x and y directions, between the inkjet print head (6) and the sheet carrier (1).

Abstract: An apparatus for optically projecting pixel-based image information onto a light-sensitive material has an image-generating device, an optical projection device, and a device for laterally offsetting the projected image of the image-generating device to produce a plurality of mutually offset partial images in the image plane. The offsetting device has two optical elements arranged in sequence in the light path of the projection. The projected partial images are offset relative to each other by tilting one or both of the optical elements.

Abstract: A device for borderless printing on imaging material by means of an ink jet printer has a support surface against which the imaging material lies while printing ink is applied to it during the printing process. The support surface has cutouts and is hydrophobic and/or oil-repellant, so as to repel printing ink that is sprayed outside the borders of the imaging material.

Abstract: A device and method are disclosed for exposing a digital image onto light-sensitive material. The device includes an image generation device that is controlled by a control device according to image data. In addition, the device has an optical system for reproducing the image onto light-sensitive material that is supported by a stage. A beam splitter, located in the exposure beam path, directs a portion of the light emitted by the image generation device onto a light sensor that has at least one sensor line.

Abstract: The invention relates to a method and device for identifying and/or correcting defects during digital image processing. Said device comprises a device for routing energy of a light source to a storage medium in the visible range of the electromagnetic spectrum, and comprises a device for generating a multitude of visible images by determining the energy from the storage medium. According to the invention, a visible image is additionally generated in the at least low color sensitivity range of the storage medium, which identifies defects and/or fluctuations in brightness during image recording. The additional visible image can be used for correcting defects of the multitude of visible images.

Abstract: A method for the automatic detection of red-eye defects in photographic image data includes the step of determining a value that provides information about the presence of a flash when recording the image data, as a criterion for the presence of such defects.

Abstract: A method for processing digital photographic image data includes a method for the automatic detection of red-eye defects. Before the image data are subjected to an elaborate process for the detection of red-eye defects, exclusion criteria are analyzed in the course of an exclusion process, whereby the criteria provide the information to definitively rule out the occurrence of red-eye defects. The red-eye detection process is not carried out if such exclusion criteria are fulfilled.

Abstract: In a method for the automatic detection of red-eye defects in photographic image data, image and/or recording data are analyzed independently of one another for several specified indications and/or prerequisites. Thereafter, a value is determined for the presence of the individual indications and/or prerequisites. Thereafter, the determined values are combined for an overall evaluation, and a decision about the presence of potential red-eye defects is made, based upon the overall evaluation. The potential red-eye defects are located, and a decision is made, based upon analysis criteria, as to whether there are, indeed, red-eye defects.

Abstract: A method and a device for reproducing originals onto light-sensitive materials is described where unsharp masks for changing the reproduction process or the density values to be reproduced are determined from the density values of the original and from pre-specified gradation factors. Several different gradation factors are used to determine the mask of an original.
