Abstract
A multicolor printing device that synthesizes a substitute color by mixing color materials to perform a printing operation with no interruption due to the reduction of the specific color material. The device judges whether the specific color material remains. If no black color material remains, the device judges whether the substitute color is to be produced. If the production of the substitute color is set, density information of the black color material is converted to density information of the three colors. Furthermore, if the residual quantity of the specific color material is below a predetermined value and if the production of the substitute color is set, density conversion of the color materials is likewise performed.
