Abstract: A readout region with a plurality of zones at grid points is scanned by a transparency or reflection reader to obtain any image data therefrom. Then, a variance of each of three primary colors of the image data is calculated, and compared with a predetermined threshold value to determine whether an original is present in the readout region. When at least one of the variances of the three primaries is greater than the threshold value, then it is determined that an original is present in the readout region.

Abstract: UCR (under color removal) amount is determined, which can satisfy printing conditions as desired easily and within short time. Gray balance for Y, M and C is inputted from input means 13. A control means 9 interpolates the inputted gray balance as necessary and instructs a test pattern generator 12 and an output unit 7 to output a test pattern so that matrix is formed by Y, M, C and K. Based on the outputted test pattern, a print plate is prepared, and a sample of matrix is prepared by 4-plate overlapping printing. Each density of matrix is measured, and said measured density value is inputted from the input means 13. The control unit 9 incorporates each density and calculates the amount of UCR, which satisfies the input gray balance from interrelation of the density of Y, M, C and K of the matrix.
