Abstract: When there is an object of a color plate which is different than a process color, it is confirmed whether or not Color (n), which corresponds to that color name Spot (n), is a spot color. If Color (n) is a spot color, CMYK value conversion is carried out from a LUT of that spot color, and CMYK values are composed in a region for output. If Color (n) is a process color, CMYK values thereof are stored in a region for CMYK color correction. After color correction is carried out on the CMYK values of the region for CMYK color correction, they are composed with CMYK values of the region for CMYK output. Color information when a color plate different than a process color is included, is generated.

Abstract: Even when an image signal is converted into an image signal with a limited amount of toner adhesion, the gradation is prevented from changing rapidly near the limiting value and therefore the image quality is prevented from deteriorating. An amount-of-adhesion converting circuit 301 converts image data for each color plane into first amount-of-toner-adhesion data. On the basis of a preset amount-of-toner-adhesion threshold value table, an amount-of-toner-adhesion reduction computing circuit 303 converts the first amount-of-toner-adhesion data for each color plane into second amount-of-toner-adhesion data with a limited amount of toner adhesion. Then, an image signal converting circuit 304 converts the second amount-of-toner-adhesion data into an image signal. In such a method, since parameters in the amount-of-toner-adhesion threshold value table are set arbitrarily, a rapid change in gradation can be suppressed near the limiting value.

Abstract: In tetrahedral interpolation suitable for data conversion implemented by digital computations, when the unit rectangular hexahedron is a regular hexahedron, no complicated multiplication is required, and the computation volume can be greatly reduced. However, when the unit rectangular hexahedron is not a regular hexahedron, since a complicated multiplication is required, the computation volume increases considerably. To avoid this, after the grid spacing is set (S1), X-u?, Y-v?, and Z-w? tables for obtaining the positions of an input value with respect to normalized grid points are prepared (S2-S4). Subsequently, image data is input (S5), and u?, v?, and w? corresponding to the input image data are obtained using the prepared tables (S6). The relationship among u?, v?, and w? is determined (S7), and data-converted image data is calculated using an equation corresponding to the determination result (S8).
