Image processing device, image forming apparatus, and non-transitory computer readable recording medium

An image processing device comprising:

• a processor that executes a screen process for image data by using different screens for first to Nth color components, where N denotes natural number equal to or larger than 2, wherein
• a primary color is the first color component,
• an i-th color is obtained by mixing i-th color component with (i−1)th color, where i denotes natural number and 2≦i≦N, and
• the image data includes at least one of the primary color to the N-th color.

An image processing device comprising:

• a processor that performs a screen process for image data by using screens which are different for first to fourth color components, wherein
• a primary color is the first color component,
• a secondary color is obtained by mixing the second color component with the primary color,
• a tertiary color is obtained by mixing the third color component with the secondary color,
• a quaternary color is obtained by mixing the fourth color component with the tertiary color, and
• the image data includes at least one of the primary color, the secondary color, the tertiary color and the quaternary color.

A non-transitory computer readable recording medium storing a program that causes a computer to execute image processing, the image processing comprising:

• executing a screen process by using screen information for a plurality of colors in an output color space including a primary color and a secondary color, wherein
• the primary color is a first color component,
• the secondary color is obtained by mixing the first color component with a second color component,
• the screen information of the primary color includes a first screen for the first color component, and
• the screen information of the secondary color includes the first screen for the first color component and a second screen for the second color component.
