Control device and control method

Abstract

To provide a control device and a control method capable of reducing the number of color patches and performing appropriate color management when color printing is performed by an image forming apparatus equipped with an inline sensor. The control device controls an image forming apparatus equipped with an in-line sensor for measuring color information of an image at a subsequent stage of a print processing part that prints an image on paper, and includes a data analysis part that extracts at least The color information included in the image of the next page after the number of printed pages from the time when the image is printed on the paper until the color information of the image is measured by the in-line sensor; The color patch corresponding to the information is arranged on a predetermined page; the control unit sends the image data of the predetermined page on which the color patch is arranged to the image forming device, and causes the image forming device to perform printing and color information measurement .

Description

technical field [0001] The present invention relates to a control device and a control method, and in particular, to a control device for controlling an image forming apparatus equipped with an inline sensor and a control method in the control device. Background technique [0002] Image forming apparatuses such as copiers and multifunction peripherals (MFP: Multi Function Peripheral) that have a color printing function are spreading. When color printing is performed using this image forming apparatus, color management for accurately reproducing colors included in each page of a job is important. Therefore, in the past, the color patch (Colour Patch) arranged at the end of the printed matter was measured by an in-line sensor installed in the image forming apparatus, and the controller controlling the image forming apparatus compared the color information extracted from the job with the color information obtained by the in-line sensor. The color information is read, and the a...

Problems solved by technology

[0008] However, in order to perform feedback control for each object type or each color space, it is necessary to arrange multiple color patches for each object type and each color space at the end of the printed matter, and ensure that the space for arranging multiple color patches is difficult

In addition, if the colors are limited to reduce the space, the color patches of the colors contained in a large number of printed materials cannot be arranged, and appropriate color management may not be possible.
