Patent ID: 8870361

Claim:
A printing device comprising: a rotatable printing cylinder; a blanket cylinder configured to make a synchronous rotation with the printing cylinder in contact with each other and to convey a printing medium by nipping the printing medium with the printing cylinder; an inkjet head that forms an image on a surface of the blanket cylinder by squirting heatset ink onto the surface of the blanket cylinder; a preheating lamp that heats up a printing surface of the printing medium conveyed into a contact portion of the printing cylinder and the blanket cylinder before the image is transferred from the blanket cylinder, a first heating unit being disposed upstream of the inkjet head in a rotational direction of the blanket cylinder, such that the first heating unit heats up the blanket cylinder from an outer periphery of the blanket cylinder before the heatset ink is squirted from the ink jet head; and a preliminary heating unit that preliminarily heats up the image formed on the surface of the blanket cylinder.
