Abstract
An illumination control method of LED lamps for ink-jet printers including a recording head in which ink discharge printing ranges are formed in a printing direction and an LED lamp in which light emitting diodes are arranged at a rear side of the recording head with respect to the printing direction. In an ink-jet printer in which the light-emitting diodes are divided into plural areas and the light amount for each area can be individually controlled by a controller, and among the light-emitting diodes, the light amount of the light-emitting diode that first scans a glossy printed surface is set to a light amount that does not cause ink curing. The light amount of the light-emitting diode of the area that first scans is set so the total light amount on the glossy printed surface is less than or equal to the critical exposure amount of the integrated illuminance.
