Abstract: A printing system for printing images, and including a system to reduce marking material coverage, while maintaining color fidelity, includes an image input, where the image defines an amount of marking material to be deposited on an printed reproduction, a marking material coverage calculator, determining expected original marking material coverage for a given area of a received image; and a marking material reduction controller, using the expected marking material determination to control coverage reduced reproduction of the given area in accordance with a non-linear coverage reduction function.

Abstract: A high capacity compressed document image storage apparatus for color printing systems.The compressed document storage system is highly suited for use with high speed color pagewidth print heads. However, the document storage apparatus can also be used with other printing systems, such as color electrophotographic and other systems.The compressed document storage system is composed of the following major components:1) an image creation system which can operate on a band by band basis.2) an input memory which stores at least one band of the uncompressed page image. Two bands are preferred to allow double buffering, so that the RIP and compression stages can proceed simultaneously.3) a page image compression system which can operate on a band by band basis. A new page image compression scheme which achieves high compression ratio and preserves high image quality is disclosed.4) a mass storage device for storing compressed page images.

Abstract: The inventon relates to a method and apparatus for marking or recording patient-related information and other necessary data in connection with X-ray imaging on a certain section of a film (6) by using a marking apparatus (2) which is movable relative to film (6). In the method, markings are made latent on film (6) in a manner that the markings become visible in connection with film development. The marking is effected as a sequence, line-directed deviation of a marking being obtained by moving the marking apparatus and the film relative to each other. The marking apparatus (2) used in the method is provided with marking elements which are brought into contact with film (6) for producing a marking on film (6), vertical deviation of alphanumerical marks included in a marking being achieved by individually controlling the operation of each marking element included in the marking apparatus.

Abstract: A plotter continuously performs a dynamic sort on incoming vectors to be plotted and stores the sorted vectors by color in bins within a memory. At the same time that the sort is being performed, the plotter selects the bin containing the most vectors and plots all of the vectors from that bin before selecting another bin.

Abstract: A flow measurement system wherein liquid to be measured is conducted through a volumeter having a pulse generator, the pulses of the volumeter are applied to an electronic counter, the output values of the counter are stored on a magnetic tape and the stored values are processed in a data processing system.
