Abstract: When color materials of more than four colors are used, a signal for the amount of toner used within a range appropriate for the apparatus and toner characteristic is generated using a color separation table. However, a printer receives print data of various formats, such as image data separated into signal values of more than four colors, or image data of a special format to which a six-color separation table cannot be applied. Hence, an image signal representing a combination of colors is input. The sum of the signal values of colors in each pixel of the image signal is calculated and compared with a limit value. When the sum exceeds the limit value, the signal values of base colors are replaced with that of a spot color based on a replacement table for replacing the signal values of the base colors with that of the spot color.

Abstract: A combination to minimize moiré can be determined theoretically or empirically in four-color printing, but it is very difficult to find a combination to minimize moiré in printing using five or more colors. To solve this problem, image data is color-separated into image data corresponding to plural colorant. Multilevel dither processing is performed to the image data corresponding to the plural colorant. At this time, dither matrices having the same screen angle, the same screen ruling, and different threshold setting methods are applied to the respective image data corresponding to dark colorant and light colorant having the same hue and different lightness values.

Abstract: There is known a technique of inputting the contents of image data and the use purpose of a print material and automatically selecting a combination of color materials appropriate for them. However, it cannot be confirmed before printing whether improvement of image quality commensurate with the cost and labor to input contents information can be obtained. To solve this problem, the ratio of the amount of the color material of a spot color used to that of the color materials of process colors used in input image data is calculated. The recommendation grade of printing using the spot color is determined on the basis of the ratio. Further, display of the recommendation grade is controlled.

Abstract: When attribute information cannot be generated from received data, image processing methods and image processing parameters are set unequivocally independently of the received data. If the same image processing methods and image processing parameters are set, processing that does not match the purpose of output or user's favor in terms of image quality may be executed. Hence, if the received data is not PDL data and does not include any interpretable attribute information, a reception print mode is checked. If “character priority” is selected for the reception print mode, attribute flag data of a character attribute is generated. If “photo priority” is selected, attribute flag data of a photo attribute is generated. If “auto” is set, automatic generation of attribute flag data is performed. When attribute flag data cannot be generated, detailed settings are checked to generate attribute flag data of a character attribute or photo attribute.
