摘要:
In a device (1) for writing image information onto recording material (2), several separate images (B1 to B13) are assigned to the image information. Marks (M1 to M14) that are assigned to the several images (B1 to B13) are applied to the recording material (2) with a marking means (3). An output unit (4) is used for outputting the image information onto the recording material (2). Using a first transport means (5), the recording material (2) is transported in the area of the marking means (3). A second transport means (6) serves to transport the recording material (2) in the area of the output unit (4). The first transport means (5) and the second transport means (6) are designed such that the transport direction (T4, R4) of the recording material in the output unit (4) can be set independently of the transport of the recording material (2) in the marking means (3).

A storage phosphor panel for storing image information and an X-ray cassette with such a storage phosphor panel are proposed. The storage phosphor panel contains a carrier layer and a storage phosphor layer, which is applied on the carrier layer. The storage phosphor panel furthermore has a contour for fixing the storage phosphor panel in a cassette.

In an apparatus for producing images on a light-sensitive material, the graphic information content for an image that is to be projected onto the light-sensitive material is divided into individual pixels. The projected image is composed of mutually offset partial images that are represented in a transmissive device consisting of an array of transmissive elements. The apparatus includes a light source that generates light rays passing through the transmissive device, an illumination device that bundles the light rays into light beams before they pass through the transmissive device, and a projection objective that projects the light beams telecentrically onto the light-sensitive material.
摘要:
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.

The invention concerns a method of testing the state of development of a photographic film in a light-proof cartridge. According to the invention, the leading edge of the film is pulled out of the cartridge, the film is positioned between a light source and a photosensor, and the amount of light passing between the light source and photosensor is measured. The state of the film is recognized as being undeveloped if a small amount of light passes therebetween.

The present invention concerns a method of making photographic prints on stock from negatives that differ in density range. The appropriateness of the exposure gradient of the stock for the particular negative is ensured by employing stock with a definite "contrast-Schwarzchild-effect" and by so varying the intensity of the light that the negative is exposed to during printing that the gradient is adapted to the characteristics of the particular negative as a function of the accordingly varied printing time.
摘要:
A spectrally sensitised photographic silver halide emulsion which is super-sensitised with an aromatic complex having a central transition metal atom which is present in a valence state which is not the highest possible for the metal concerned and which complex contains at least one non-aromatic complex ligand, is distinguished by increased sensitivity.
摘要:
A filmstrip consisting of a series of coherent frames is passed through a copying station where images of the frames are projected onto an elongated band of copying paper to make proofs of the frames. The images are projected in such a manner that the relative orientations of the images are the same as the relative orientations of the frames.
摘要:
Mouldings made from polyacetylene-containing polymer products comprising poly-acetylene and a polymer other than polyacetylene are distinguished by improved stability of their optical and electrical properties in air when they have a protective coating of a silicate.
摘要:
A device for processing photographic materials comprising at least one liquid-filled tank and liquid from the liquid-filled tank is removed from the photographic material and lead back to the same tank. The tank comprises several pairs of rollers placed one above the other above the liquid level of the tank or downstream of the tank. The rollers of each pair of rollers are parallel to one another. At least one pair of rollers is provided with a liquid supply directed to the pair of rollers to provide a system for efficient cleaning of the photographic material. The rollers have an adjustable pressure device and a specific pressure range.
