4590515 Method and apparatus for modifying color reduction depending on tone May 20, 1986
A four color printing system wherein tone dependent color reduction is to be utilized and the color components for the chromatic printing inks yellow (Y), magenta (M) and cyan (C) are reduced and the amount of black printing ink (K) is increased so as to compensate for the reduction in t
4516155 Method for partially smoothing retouch in electronic color reproduction May 7, 1985
A method for smoothing retouch in electronic color image reproduction employs a coordinate pen used by the retoucher as a retouch brush, to identify image point coordinates within an image point area. The color values associated with the image point coordinates are changed as a funct
4486772 Method and circuit arrangement for partial correction of the delineation in color image reproduc December 4, 1984
The invention relates to a method for improving the delineation in color image reproduction by means of a partial, electronic retouch. The color values of the individual color separations gained by means of image point-wise, trichromatic color image scanning and digitization are depo
4476487 Method and circuit arrangement for partial electronic retouch in color image reproduction October 9, 1984
The invention relates to a method for partial electronic retouch in color image reproduction. The color values of the individual color components gained by means of image point-wise, trichromatic color image scanning and digitization are deposited in a storage medium (1). The image point
