Claim 6:
7. The illumination control method of LED lamps for ink-jet printers according to claim 1, wherein the setting of the light amount of the light-emitting diodes divided into a plurality of areas is carried out through: a first process of measuring the illuminance distribution on a printed surface of each of the divided light-emitting diodes by driving an LED lamp of a test ink-jet printer; a second process of obtaining the integrated illuminance distribution on the printed surface of each of the divided light-emitting diodes using the data measured in the first process and the integrated illuminance distribution on the printed surface of the entire LED lamps obtained by summing these; a third process of adjusting the illuminance of each of the divided light-emitting diodes on the printed surface on the basis of the integrated illuminance distribution; and a fourth process of setting the light amount of each of the divided light-emitting diode in such a way that the integrated illuminance on a gloss-printed surface is no greater than a critical amount of exposure.
