Claim:
1. A signal conversion method for converting an image signal in order to limit a total amount of color materials used in a printing device that forms an image on a recording medium using a plurality of color materials, comprising: preparing a plurality of input/output signal conversion processes based on different limit values such that a plurality of results of conversion from an input vector to a vector in which the total amount of color materials used is limited to a value equal to or less than the limit value are generated; and determining a final output vector after the total amount of color materials used is limited for the input vector, on the basis of the plurality of input/output signal conversion processes and weight definition information in which weights applied to the conversion results of the plurality of input/output signal conversion processes are determined according to the input vector; and further comprising:
