Patent ID: 7898704

Claim:
An image output controller which is capable of directly or indirectly controlling a printer printing a color chart comprised of an optionally settable color chart and a color measuring apparatus carrying out color measurement for the color chart, wherein: when color authentication is executed for an optionally set image, a process is carried out in relation to user's setting or automatic optimization including at least one of a printing position of the color chart, a layout of the color chart and a color value of the color chart; the printer is controlled according to a printing condition based on the user's setting or the automatic optimization so that the color chart is printed on a sheet of predetermined printing paper; the color measuring apparatus is controlled so as to carry out color measurement for the printed color chart, the printer repeats both printing while paper feed is stopped and paper feed every line in a widthwise direction of the paper perpendicular to a direction of paper feed, thereby printing any image on predetermined printing paper; and in a process related to automatic optimization of the layout of the color chart, in order that a printing position of the printer and a color measuring location of the color measuring apparatus may be consistent with each other, the number of color charts per unit width in the feed direction of the printing paper is automatically set according to a time ratio of a printing time while feed of the printing paper is stopped and a time necessary for the color measuring apparatus to scan one widthwise line of the printing paper.
