    Abstract: A calibration system includes an image forming apparatus, a color-measurement device, a primary-color-input-output-characteristics adjustment unit, and a secondary-color-input-output-characteristics adjustment unit. The primary-color-input-output-characteristics adjustment unit adjusts input-output characteristics of a primary color of the image forming apparatus by correcting a gamma correction table for the primary color. The secondary-color-input-output-characteristics adjustment unit adjusts input-output characteristics of a secondary color of the image forming apparatus by correcting the gamma correction table for the primary color using the measurement results of the chart for the secondary color. The chart for the secondary color is printed by the image forming apparatus after the adjustment. The secondary-color-input-output-characteristics adjustment unit, as a combination ratio of two color materials, obtains the combination ratio where a hue angle of the specific secondary color becomes a defined hue angle so as to correct the gamma correction table for the primary color corresponding to the obtained combination ratio.

    Abstract: A color conversion method according to the present invention, in which a scanner that outputs a first color value of a device-dependent color space is used, includes the steps of: acquiring the first color value by reading, by the scanner, a printed material which is based on image data composed of C, M, Y, K values; converting the acquired first color value to a second color value using a scanner profile of the scanner; mapping the first color value acquired from the printed material to the K value of the image data of the printed material; determining a correction quantity of the second color value from the mapped first color value and the K value using a scanner profile correcting LUT; and correcting the converted second color value using the determined correction quantity of the second color value, and outputting the second color value after being corrected.

    Abstract: There are provided a printing system, a method of generating a halftone processing rule, a method of acquiring a characteristic parameter, image processing device and method, a halftone processing rule, a halftone image, a method of manufacturing a printed material, an ink jet printing system, and a program which are capable of reducing an operation load of a user and acquiring a halftone processing rule appropriate for the printing system. A characteristic parameter acquisition chart (100) including a pattern for acquiring characteristic parameters related to characteristics of the printing system is output, and the output characteristic parameter acquisition chart (100) is read by image reading means. The characteristic parameters are acquired by analyzing the read image of the characteristic parameter acquisition chart (100), and halftone processing rules that define the processing contents of halftone processes used in the printing system are generated based on the acquired characteristic parameters.
