Abstract:
1. A printing device using thermal roll imprinting and a patterned plate, comprising: a first supply roll continuously supplying a patterning film; a heating roll and a first sub-roll imprinting a first pattern in the patterning film supplied from the first supply roll by pressing the patterning film from both sides thereof to form a patterning plate; an imprinting mask provided with an original pattern to be imprinted to the patterning film and mounted on the surface of the heating roll; a cooling device provided downstream of the heating roll and the first sub-roll along a transfer direction of the patterned plate to cool the patterned plate imprinted with the first pattern; a rotatable inking roll inking the first pattern imprinted to the patterned plate by winding the patterned plate; a doctor blade forming a second pattern by inking ink to a concave portion of the first pattern or removing residual ink in a convex portion in the patterned plate; a first recovery roll provided downstream of the rotatable inking roll along a transfer direction of the patterned plate to recover the patterned plate; a blanket roll forming a third pattern on the blanket roll by pressing the patterned plate from both sides thereof together with the rotatable inking roll and receiving the ink from the patterned plate; and a second sub-roll forming a fourth pattern by pressing a printing film from both sides thereof together with the blanket roll and printing the third pattern of the blanket roll to the printing film.
