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

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.

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.

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.

A copying apparatus is adjusted in order to produce high-quality copies of transparent negatives or diapositives having excessive variations in brightness. The adjustment is performed using a reference master. The apparatus is properly adjusted when a copy of the reference master meets specific criteria.

An apparatus for processing film has two processing units and transport rollers for conveying film past the units. One of the units may include a scanning device and the other unit may include a copying device. Alternatively, the two units can comprise a prescanning device and a main scanning device, respectively. The apparatus further has a receiving station for film cartridges and at least one separate receiving station for film which is not confined in cartridges. Film can be fed to the transport rollers from either station.

Processing apparatus for film

Photographic printing apparatus is disclosed with a common guidance and transport device for the films. Several entry points are adapted in size and shape to various films and/or cartridges. Each of these input points has a separate guidance and transport device. A transfer station is provided which transports the films from the guidance and transport devices of the entry points into the common guidance and transport device through the printing apparatus.

A length of exposed film has a timing track which extends along one of the longitudinal margins thereof. The timing track includes a begin segment having a first width, an end segment having a different second width and a grating between the segments. The grating consists of alternating light and dark segments having a uniform width different from the widths of the begin and end segments. The two longitudinal margins of the film are scanned by respective sensors as the film advances towards a film processing apparatus. Whenever a segment passes by a sensor, the width of the segment and its position in the timing track are recorded. Since the widths of the begin and end segments differ from the width of the grating segments, the position of the begin or end segment relative to the grating can be established. This information, combined with a knowledge of which sensor detected the timing track, makes it possible to determine the orientation of the film.

Method of and apparatus for determining the orientation of film

A photographic copier has an adjustable masking device for masking a master to be reproduced. To determine whether masking is required and, if so, the degree of masking, the density of the master is measured and is then forwarded to a logic circuit which can make the determination. In a first mode of operation, masked and unmasked images of the master are displayed side-by-side on a pair of monitors so that an operator can make adjustments to the mask calculated by the logic circuit. The operator here controls the copying cycle. In a second mode of operation, the copying cycle is automated and the logic circuit decides whether masking is required by calculating a degree of masking and comparing the degree of masking with a relatively low reference value set by the operator. The master is copied without a mask when the calculated degree of masking is less than the reference value. If a copy made by masking is unsatisfactory, the operator can adjust or deactivate the logic circuit and make a new copy. In a third mode of operation, the reference value set by the operator is high. When the calculated degree of masking exceeds the reference value, the logic circuit asks the operator to make a decision on masking. To this end, the logic circuit interrupts the automatic copying cycle and calculates a proposed mask which is then displayed for the operator.
