Title:
MULTI-COLOR GRAVURE OFFSET PRINTING DEVICE AND PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/188767
Kind Code:
A1
Abstract:
The present invention relates to: a printing device for performing a multi-color gravure offset printing operation, in one rotation of a gravure offset roll, for various shapes of printing material; and a method therefor, and the purpose of the present invention is to provide a printing device for performing multi-color gravure offset printing on a flat surface, a cylindrical surface, or a stereoscopic shape such as a three dimension, by using one blanket roll in one printing cycle, and a method therefor. To this end, the present invention provides a gravure offset printing device comprising: a blanket roll having a cylindrical shape, and moving in a first direction while rotating; an ink transfer unit including one or more ink transfer plates which is in contact with a lower end of the blanket roll; a squeeze unit moving in a second direction in a state in which one end thereof comes in contact with the ink transfer plate, wherein the second direction forms a predetermined angle with respect to the first direction or is orthogonal to the first direction. According to the present invention, an effect of enabling gravure offset printing in one printing cycle, on various shapes of printing material is provided. Particularly, gravure offset printing is enabled not only on a flat surface printing material but also on a cylindrical printing material and a three-dimensional stereoscopic printing material, having a thickness, including a curved surface structure. In addition, according to the present invention, printing can be performed such that inks of various colors are overlapped respectively on the same location on a printing material, thereby providing an effect of enabling printing of a desired color in one printing cycle by combining the ink colors.
