Abstract
An image is printed in an image print area on a recording medium by using a first printing material. Information is printed on an image preservation determination portion in a border portion as an area other than the image print area by using a second printing material which deteriorates faster than the first printing material. This portion is stored as density data, color appearance data, or the like in the apparatus to be used as a criterion for determination of deterioration when the image is to be reused.
