摘要	PROBLEM TO BE SOLVED: To shorten a printing tact and to completely transfer print an ink by providing an ink supply unit before a doctor unit to an intaglio pattern, and simultaneously performing supplying of the ink and doctoring. SOLUTION: A doctor blade 4 is mounted at the same horizontal bar as a dispenser 3, and as the bar is moved in a printing direction, ink discharging and doctoring are simultaneously conducted. At this time the ink supply dispenser 3 discharges the ink while moving to reciprocate in a direction perpendicular to the printing direction, and hence the ink is supplied in saw blade shape 6 over the entire surface of the intaglio pattern. Immediately thereafter, since the ink is doctored by the blade 4 mounted at the same bar, printing can be executed without stopping time of the printer. At this time, since the doctoring is conducted immediately after the ink is supplied, no ink is dried, and the ink is charged in a homogeneous state. As a result, printing can be conducted without defect over the whole of pattern.
