    摘要: As a means of providing for a register-true chucking of printing plates to a plate cylinder for an offset printing press, the plate cylinder is provided with a seating surface for receiving thereon a forward edge of the printing plate and a series of chuck levers for clamping the plate against the seating surface. The chuck levers pivot about a common shaft extending axially with the cylinder and are driven by means of articulated link arrangements extending from a rotatable shaft parallel with the pivot shaft. The levers are divided into first and second types, the first type having a coupler linkage designed as a pressure spring and the second type having non-resilient linkage means such that the first group of levers engage the plate ahead of the second group. The levers are each formed with a clamp surface. The clamp surface of the levers and pressure surface on the cylinder are formed with grip means for locking the forward edge of the plate onto the pressure surface. The gripping means for the second type of levers comprises a stamping device for cutting and fitting sections of the printing plate into corresponding recesses formed in the pressure surface of the plate cylinder. The grip means for the first type of levers comprises corresponding pin and perforation devices.

    摘要: A color correction technique is disclosed in which standardized color correction signals are stored in an addressable memory which emits a plurality of digitalized trichromatic picture scanning values as input values in a corresponding plurality of corrected picture recording signals as output values. An assignment of memory input to memory output is fed into the memory as standardized color correction data before reproduction. For a location to be specially corrected, the color signals thereof are measured and compared with predetermined values and a difference formation is provided between the memory output signals and the predetermined values, the difference values being stored and utilized, in connection with distance calculations of neighboring points, to input re-corrected color correction values into the addressable memory.

    摘要: The invention relates to facsimile reproduction and particularly to a method for converting a video signal obtained by scanning an original dot by dot and line by line, into a bilevel black/white signal.In the black/white recording of colored originals in which both the background and the information can be white, black, grey or colored, grey/black transitions coming from "white" and grey/white transitions coming from "black" are frequently not evaluated correctly by the dynamic threshold so that information is lost in the copy.In order that these types of transitions are also detected, it is suggested to eliminate the DC component of the video signal and to compare the video signal modified in this way with a second dynamic threshold signal derived from it. The comparison signal is logically linked to the customary black/white signal in such a manner that the black/white signal is flipped to "white" at a grey/black transition and to "black" at a grey/white transition in each case for a specified time interval.In this manner, for example between a colored area in the original recorded as "black" and a black letter in this area, a white boundary line is created which makes the front contour of the letter visible. Similarly, between a colored area in the original reproduced as "white" and the white edge of the original copy a black boundary line is generated which makes the contours of the colored area in the original clearly recognizable.

    摘要: The invention relates to a method of determining the standard color data of colors represented on a color monitor. Within a color represented on the color monitor there is fixed a measurement area in which the color measurement data are determined. From the color measurement data there are calculated the corresponding standard color data of the color selected by the measurement area, taking into account the tube characteristics and the standard color data of the individual phosphors of the color monitor.The accuracy of the determination of standard color data can be increased by multiple measurement within the measurement area.The calculated standard color data are, for example, the starting quantities for a color mixture calculation by means of a color formula computer.

    摘要: A method of avoiding unwanted line structures in the electronic reproduction of images by means of a monochromatic light source in whose beam path an acousto-optic modulator (AOM) cell is arranged. One line consists of a multiple line made up of a plurality of sub-lines. The acousto-optic modulator (AOM) cell is driven by a mixture of ultrasonic waves of discrete frequencies, by which means the beam is split up into a plurality of sub-beams each associated with a discrete frequency which together determines the line width. The individual frequencies are so calculated that the sub-beams overlap and so that the amplitudes of the frequencies produce a uniform intensity distribution in a line.

    摘要: The method of electro-optically scanning a picture with a multiple electrical optical scanning head which can be laterally moved across the picture and the outputs of the multiple scanning head are supplied to a first group of shift registers so that individual lines of scanned information will be stored in individual shift registers. After the k lines of information have been scanned and stored in the first group of shift registers the scanning element is shifted to scan additional lines and the output of the multiple scanning device is supplied to a second plurality of shift registers to store information in this group of lines. When information is being written in the second group of shift registers the first group of shift registers are connected to a transmitter to serially transmit line by line the stored information. While information is being written into the first group of shift registers the second group of shift registers are connected to a transmitting medium to transmit the stored information line by line. A similar receiver with third and fourth group of shift registers is used to reproduce the information at a receiving site.
