Image processing apparatus for primary color and spot halftoning
Abstract:
An image processing apparatus includes processing circuitry. The processing circuitry is to acquire image data including primary color image data for primary color and spot color image data for spot color; generate primary color halftone data representing the primary color image data as a group of halftone dots, using a primary color screen specifying cyclic arrangement of lines of halftone dots; and generate spot color halftone data representing the spot color image data as a group of halftone dots, using a spot color screen having a second phase that is different from a first phase represented by the cyclic arrangement of lines specified in the primary color screen.
