Calibration performed in image formation apparatus to maintain image quality

摘要

An image formation apparatus performs calibration to maintain image quality. An adding unit performs addition processing to add an arbitrary type of printing medium different from a printing medium designated in advance as a printing medium usable for the calibration. A storage unit stores characteristic information indicating characteristics of each of a plurality of arbitrary types of printing media added by the adding unit. A determination unit determines an arbitrary type of printing medium relatively approximate to the characteristics of the printing medium designated in advance by comparing the characteristic information of each of the plurality of arbitrary types of printing media with the characteristics of the printing medium designated in advance. A calibration performing unit performs the calibration using the printing medium determined by the determination unit.

1. An image formation apparatus comprising:
a correction unit configured to correct image data based on a tone correction condition; an image forming unit configured to form an image on a printing medium based on the image data corrected by the correction unit; an obtaining unit configured to obtain luminance data of a measurement image formed on the printing medium by the image forming unit; a generation unit configured to convert the luminance data obtained by the obtaining unit into density data based on conversion setting information corresponding to the printing medium and to generate the tone correction condition based on the density data; an adding unit configured to add conversion setting information corresponding to printing medium; a storage unit configured to store another conversion setting information and characteristic information of another printing medium corresponding to the conversion setting information added by the adding unit; a determination unit configured to determine a target printing medium to be formed with the measurement image, based on the other characteristic information stored in the storage unit; and a control unit configured to control the image forming unit to form the measurement image on the target printing medium determined by the determination unit, to control the generating unit to convert luminance data obtained by the obtaining unit from the measurement image formed on the target printing medium into density data based on target converting setting information corresponding to the target printing medium, and to control the generating unit to generate the tone correction condition based on the converted density data.
