Patent ID: 8437042

Claim:
An image forming system, comprising: a processing unit; a memory that stores computer-executable instructions that when executed by the processing unit cause the image forming system to function as a setting unit that allows a user to set color adjustment parameters to be used to print out a main image according to main image data; an information image data generating unit that generates information image data representing values of the color adjustment parameters when a user sets the color adjustment parameters to be used to print out the main image; a print data generating unit that generates print data based on the main image data; a drawing area data generating unit that generates drawing area data based on the main image data, the drawing area data representing a drawing area where characters or figures are formed in the main image; a judgment unit that identifies a marginal area of the main image, the marginal area being an area of the main image other than the drawing area and which constitutes a blank space, and determines whether an information image represented by the information image data is to be printed in the marginal area; a combining unit that combines the information image data with the main image data based on the determination made by the judgment unit, to generate combined image data when a user sets the color adjustment parameters to be used to print out the main image; and a printing unit that prints the print data generated by the print data generating unit, wherein, when a user sets the color adjustment parameters to be used to print out the main image, the print data generating unit generates the print data by performing color conversion of the combined image data in accordance with the color adjustment parameters set by the user, and the printing unit prints an image according to the main image data and the information image represented by the information image data in the main image.
