Embodiment 1

[0046] and Figure 3 ~ Figure 8 The production method shown is the same, and a large resin relief plate is produced by connecting two resin relief plates. In the manufacture of this large-sized resin relief, an alignment sheet having a width of 0.1 mm was used for positioning the resin relief after cutting the edge portion. As a result, in the large resin relief plate manufactured, the space between the opposing side faces in the joining portion was 0.1 mm.

Embodiment 2

[0048] In said Example 1, the sheet|seat for alignment which set the gap between the new side surfaces formed by the said cutting to width 0.8mm was used as the sheet|seat for alignment. Except for this, a large-sized resin relief plate was produced by the same method as in Example 1 above. As a result, in the large resin relief plate manufactured, the space between the opposing side faces in the joining portion was 0.8 mm.

Embodiment 3

[0050] In said Example 1, the sheet|seat for alignment which set the gap between the new side surfaces formed by the said cutting to width 1.8mm was used as the sheet|seat for alignment. Except for this, a large-sized resin relief plate was produced by the same method as in Example 1 above. As a result, in the large resin relief plate produced, the space between the opposing side faces in the joining portion was 1.8 mm.

Abstract

PROBLEM TO BE SOLVED: To provide a manufacturing method for a large-sized resin relief printing plate, which can make a printing area wider by making the width of a connected section narrower, in the resin relief printing plate which is enlarged by connecting a plurality of resin relief printing plates, and to provide a large-sized resin relief printing plate obtained by the manufacturing method.SOLUTION: The end edge sections of the resin relief printing plates 1 and 2 which are connected with each other are positioned and stacked at alignment marks 11 and 21 for stack-positioning. Under this state, the stacked parts are simultaneously cut up to down along the side surfaces at specified positions to the alignment marks 11 and 21 for stack-positioning. By this cutting, new side surfaces (cut surfaces) which are formed at a high accuracy and a high efficiency can precisely be butted to each other. As a result, an interval between the side surface and the side surface which are confronted at the connected section can be extremely narrowed to a width of 0.1 to 5.0 mm.

Description

technical field [0001] The present invention relates to a method for making a large-scale resin relief formed by connecting multiple resin reliefs and the large-scale resin relief obtained by the method. Background technique [0002] Conventionally, a resin relief plate on which a printing convex portion serving as a printing area is formed is used in various relief printing such as a flexographic printing method. Furthermore, in recent years, alignment films and insulating films are generally formed on the surfaces of TFT substrates and color filter substrates used in color liquid crystal televisions by flexographic printing. [0003] Color liquid crystal televisions are increasing in size year by year, and it is necessary to increase the size of the resin letterpress accordingly. In order to cope with the recent enlarged color liquid crystal televisions, it is necessary to set the size of the resin relief plate to, for example, about 2500 mm×3000 mm. However, resin relie...
