In washing off an ink in a flexographic printing press, washing water on a seal blade is removed rapidly at low cost. The apparatus includes a washing water supplying path 31, 32 that is connected to an ink chamber 5, the ink chamber 5 including a seal blade 3 and a doctor blade 4 being in slidable contact with an outer circumference of an anilox roll 1; a washing water supplier 30 that supplies washing water to an inside of the ink chamber through the washing water supplying path; a supplying path opening/closing device 9 that opens and closes the washing water supplying path; a washing water recovering paths 11, 21, 23 that are connected to the ink chamber; a suction recovering device 7 that recovers the washing water in the ink chamber by suction through the washing water recovering path; and a controller 100 that controls operations of the washing water supplier, the supplying path opening/closing device, and the suction recovering device in a predetermined control mode, wherein the control mode comprises a decompression control mode in which the seal blade is elastically deformed towards the ink chamber by decompressing the inside of the ink chamber by recovering the washing water by suction generated by activating the suction recovering device and closing the washing water supplying path by the supplying path opening/closing device. |
