Multicolor ink jet recorder

Abstract

Abstract PURPOSE:To prevent fluctuation of an image due to change of recording paper size and water absorptivity, etc., by calculating correction conversion of original color component signals on the basis of detection signals corresponding to temperature and humidity detected with a temperature detector and a humidity detector, respectively. CONSTITUTION:A temperature detector 15 (116), for example, a thermistor lowers in resistance with rise of temperature. A humidity detector 118 lowers in resistance with rise of relative humidity. Color component signals of a color original 2 read out by a reader 5, a temperature detection signal detected with a temperature detector 15 (116), and a humidity detection signal detected with a humidity detector 16 (118) are fed to a color signal correction control circuit 121. Color component signals are corrected on the basis of the temperature and humidity detection signals to feed the conerted color component signals for recording and to control an injection nozzle 6, thus permitting image fluctuation due to change of recording paper size, water absorptivity, etc. to be prevented.
