Ink-jet print method, ink-jet print apparatus used in ink-jet print method, and ink-jet print obtained by ink-jet print method

摘要

An image is printed in an image print area on a recording medium by using a first printing material (S9). 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 (S10). 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 (S4, S5).
