摘要： Disclosed is a printing machine for corrugated board sheets, which is designed to facilitate the procedures of ink change in accordance with order changes in the printing of corrugated board sheets by using a low viscosity and quick-drying glycolic ink, in which the residual ink of the previous order can effectively be recovered so as to minimize the amount of the ink to be wasted. The printing machine having a plate cylinder with a printing die mounted thereon and an impression cylinder disposed to oppose to the plate cylinder, rotatable in the different rotational directions, in which corrugated board sheets are designed to pass through the clearance between the plate cylinder and the impression cylinder to carry out printing in a predetermined pattern, the printing machine further comprising an ink transfer roll which rotates in contact with the printing die; a squeezing roll which rotates normally in contact with the ink transfer roll during operation of the printing machine to adjust the amount of the ink on the surface of the ink transfer roll; a supply unit to selectively supply a low-viscosity and highly quick-drying ink or a cleaner to the ink fountain defined between the rolls; a pair of dams to selectively open and close the both longitudinal extremities of the ink fountain; and a scraper which scrapes off the ink or the ink washing waste transferred to the roll when the scraper is brought into contact therewith.
