摘要： A method for the color evaluation of pattern models of fabric, decoration or packaging printing which, in particular, exhibit bleeding color areas, i.e. color areas of differing color saturation and/or brightness, and a color evaluation device with a color monitor is provided for carrying out the method. Color recognition signals characteristic for the individual pattern colors and a run signal, dependent on the respective color saturation, are derived from the color measured value signals obtained through opto-electric scanning of the pattern models. A freely-selectable color signal triad corresponding to the color to be displayed on the color monitor is assigned in a coloration unit to each pattern color and a further color signal triad is prescribed for the background color of the later printing medium. For displaying the pattern models on the color monitor, the color recognition signals in the coloration unit call in the color signal triads. The control signals for the color monitor are determined from the color signal triads called in, from the color signal triad of the background color and from the run signal.

摘要： A method and apparatus for isochromatic simulation of a multi-colored reproduction on a color monitor. Before simulation, colors are generated on the color monitor and are matched to corner colors of a printed color chart or the like by measuring or visual comparison. The color values required for the chromatically coinciding generation of the corner colors on the color monitor are measured and allocated to color separation values of the corner colors. The color values required for generating intermediate colors are calculated upon consideration of the printing process of the multi-colored reproduction and are allocated to the corresponding color separation values of the intermediate colors. During the simulation, the color separation values of the multi-colored reproduction are output, modified according to a gradation curve, and transformed into the color values for driving the color monitor in accordance with the previously identified allocations.

摘要： Given color reduction depending on tone in four-color printing, wherein the color components of the chromatic printing inks yellow, magenta and cyan are reduced and the amount of black printing ink is increased to compensate for such reduction, a achromatic synthesis is employed up to a gray tone value which corresponds to the full tone of the black printing ink employed and the color components of the chromatic printing inks are again increased proceeding from that gray tone value up to the maximum shadow in order to get desired densities in the overprint.

摘要： A method and circuit arrangement for selective correction of hues and colors in the production of color separations for polychromatic mixed printing. A hue signal identifying the hues of the scanned colors as well as a color saturation signal and a luminance signal are derived from the measured color value signals acquired when scanning the original. Hue signals, color saturation signals and luminance signals are limited such that they are respectively not equal to zero only for selectable regions. The region of the hue signal defines a hue to be selectively corrected, and all three regions of the signals define a color to be selectively corrected. At least one of the limited signals is combined with at least one of the unlimited signals to form the selective correction signals which are superimposed on the color signals to be corrected.

摘要： Method and apparatus for recording color pictures wherein color proofs are made before the actual printing for quality control in multicolor printing processes. The color pictures are exposed on a chromatic material wherein the exposed colors must coincide with the colors which are later to be printed on paper. So as to achieve the color equivalent color picture exposure, the required color density values for the chromatic material of the selected printed and exposed colors are identified with a visual or mensurational comparison of the CIE coordinates. The identified color density values for the exposed colors are allocated to the corresponding color separation values of the colors to be printed and during recording the allocated color density values are utilized instead of the color separation values and are converted into signals for driving a color exposure unit for example a proof recorder.

摘要： Apparatus and method for producing qualitatively high-grade color images of originals such as copy masters for multi-color or process printing by exposing chromatic material wherein the originals are scanned point-by-point and line-by-line and the color signals thus obtained are converted into color density values for the chromatic material by means of a correction of color and of gradation. The drive values for a color exposure unit which exposes the chromatic material point-wise and line-wise are generated from the color density values using a linearization process. As a result of signal inversion color positive originals can be recorded as color negatives and vice versa. The exposure process can be matched to every chromatic material independently of the nature of the original to be reproduced and the state of the developing process by means of changing the color density values according to an arbitrarily selectable correction function and by means of signal inversion.

摘要： In electronic reproduction technology, a recognition circuit for hues and colors in colored surfaces is provided. Before the actual hue recognition, the hue to be recognized is selected and its prescribed or measured color values of the RGB color space are transformed by a first color transformation into chrominance values of the chrominance/luminance color space, whereby the transformation coefficients are defined such that the transformed color locus of the hue to be recognized lies on a rotated X'Y' color coordinate system in the chrominance plane. During the actual hue recognition, the colored surface is opto-electronically scanned and the measured color values acquired are transformed into chrominance values by a second color transformation with the transformation coefficients defined in the first color transformation. By selection of chrominance values and by quotient formation of the selected chrominance values, a hue signal which is a measure for hue deviation of the scanned hues from the hue to be recognized is generated. After combination of the hue signal with an auxiliary control signal, a hue recognition signal is formed, this being unequal to zero when the scanned hues lie within a sector-shaped hue recognition region. For color recognition, a color saturation signal and a luminance signal are additionally generated. The color saturation signal and luminance signal are adjustably limited in terms of amplitude and are combined with the hue recognition signal to form a color recognition signal.
