Abstract
The present invention relates to a roll stamp and a method of manufacturing the same, the roll stamp including a cylindrical metal mold including a debossed pattern formed on an outer side and a hollow portion formed on an inner side, and a dummy roller inserted into the hollow portion. Because a joining portion is not formed on the entire area of the cylindrical metal mold, a problem in which edge regions are separated does not occur. Also, due to the absence of the joining portion, it is possible to perform a patterning process continuously.
Claims8
A method of manufacturing a roll stamp, the method comprising:
- providing an object including a first embossed pattern;
- placing a first resin layer on an upper surface of the object including the first embossed pattern and pressing the first resin layer;
- manufacturing a first resin mold including a first debossed pattern by separating the first resin layer from the object;
- forming a first metal layer on an upper portion of the first resin mold including the first debossed pattern;
- manufacturing a first metal mold including a second embossed pattern by separating the first metal layer from the first resin mold;
- forming a second metal layer on an upper portion of the first metal mold including the second embossed pattern;
- manufacturing a second metal mold including a second debossed pattern by separating the second metal layer from the first metal mold;
- placing a second resin layer on an upper surface of the second metal mold including the second debossed pattern and pressing the second resin layer;
- manufacturing a second resin mold including a third embossed pattern by separating the second resin layer from the second metal mold;
- manufacturing a cylindrical resin mold by rolling the second resin mold so that the third embossed pattern is placed on an inner circumference side of the cylindrical resin mold;
- forming a third metal layer having a cylindrical shape on the inner circumference of the cylindrical resin mold;
- manufacturing a cylindrical metal mold including a third debossed pattern formed on an outer side and a hollow portion formed on an inner side by separating the third metal layer having a cylindrical shape from the cylindrical resin mold;
- arranging dies at a predetermined distance from the cylindrical metal mold;
- filling a space between the cylindrical metal mold and the dies with a filler;
- manufacturing a cylindrical filler mold including a fourth embossed pattern formed on an inner circumference and a hollow portion formed on an inner side by separating the dies and the cylindrical metal mold from the filler;
- filling the hollow portion of the cylindrical filler mold with a metal material;
- and
- separating the cylindrical filler mold from the filled metal material.
