c, m, and y, which are the primary colors, are calculated from inputted RGB data. Duty limitation is then applied to c, m, and y by means of the limit amount alpha. c', m', and y', which have been limited by alpha, are then normalized. The largest limit amount is beta when the normalized values are less than 200%. If these values are between 200% and 250%, beta+((c''+m''+y'')/255-2)x2gamma is then the largest limit amount, which is beta+gamma when the values are equal to or more than 250%. C, M, Y, and K are obtained by subjecting c', m', and y' to under color removal and black generation processing. Unless the total of these values exceeds the largest limit amount, C, M, Y, K are outputted as is as the output values C', M', Y', and K'. When the largest limit amount is exceeded, Duty limitation is applied.
