The invention provides a marking press for corrugated paper. The marking press comprises a longitudinal marking device, a prepressing wetting device, a front conveying device and a rear conveying device, wherein the longitudinal marking device comprises two upright columns arranged symmetrically, a cross rod, air cylinders, a pressing roll, pressing wheels and a supporting roll; the cross rod is arranged at the top ends of the two upright columns; the air cylinders are arranged on the cross rod; output rods of the air cylinders are connected with shaft sleeves; the pressing roll is rotationally mounted in the shaft sleeves; axial positions of the pressing wheels on the pressing roll are adjustable; the prepressing wetting device comprises two connecting rods arranged symmetrically, a rotating roll, prepressing wheels, spongy layers and first water spray pipes; the prepressing wheels are arranged on the rotating roll, and correspond to the pressing wheels one to one; axial positions of the prepressing wheels on the rotating roll are adjustable; the widths of prepressing wheels are greater than those of the pressing wheels; the spongy layers are arranged on the outer sides of rolling surfaces of the prepressing wheels; and water outlets of the first spray water pipes are formed above the rotating roll. The marking press is wide in application scope; pressing marks have various forms; the depths of the pressing marks are controllable; and no tearing can be caused at a pressing mark place in a marking process.
