摘要： A color correction method applicable to a digital processing type of color copier, whereby a set of color patches of respectively different sample colors is printed using a set of printing data values, the color patches are then scanned and analyzed to obtain color patch input data values by the color copier, and each of all of the possible input color data values that can be produced by the scanner/analyzer section of the color copier is then related to one of the color patch input data values which is closest thereto in a 3-dimensional color space. Each of these possible input color data values is thereby related to an appropriate color printing value, whereby a color correction table can be generated which provides correction accuracy that is independent of non-linearity of color printing characteristics.

摘要： A halftone signal having one of two discrete levels is generated for each print position along each print line by comparison between a gray scale value of an original with a threshold value stored in a memory. The memory has an .alpha.M.times..beta.N matrix array of cells each storing a particular threshold value, where M, N, .alpha. and .beta. are integers. The memory is divided into .alpha..times..beta. identical imaginary matrices of M.times.N elemental areas each containing a cell in a particular one of .alpha..times..beta. positions. The threshold values stored in each imaginary matrix have a prescribed ordered-dither distribution and those stored in positionally corresponding elemental areas have a dot-dispersive or a dot-concentrative distribution. The memory is addressed in a given direction in response to each print position and in a direction normal to the given direction in response to each print line to read a stored threshold value for each print position for comparison with the gray scale value.
