摘要	PURPOSE:To improve reproducibility responsive to printing tone of an original plate by coating a gravure lithography with ink by a first doctor blade, and removing excessive ink by a driven second doctor blade. CONSTITUTION:A first doctor blade 3 is drawn on a gravure lithography 1 to coat the whole surface of the lithography 1 with ink (a), thereby filling the ink (a) in the cells of the lithography 1. Thus, the cells of the lithography 1 become the same state as that an original plate is dipped in the ink. Then, a second doctor blade 4 in contact by driving is drawn on the lithography 1 to scrape off excessive ink, and an impression cylinder 2 is then rolled to transfer the ink to a printing sheet (b). Since the ink filling state of the cells of the lithography becomes similar to that of the cells of this plate, reproducibility corresponding to the printing tone of this printer is improved.
