Method for processing concave-convex areas of picture

Abstract

The invention discloses a method for processing concave-convex areas of a picture. A coiled picture has at least two concave-convex areas which need to be processed. The method comprises the following steps: detecting appointed color codes on the picture by utilizing a slitting photosensitive probe, and cutting along the detected appointed color codes by a slitter of slitting equipment to obtain a large picture; delivering the large picture into a die cutting machine so as to enable the cut face of the large picture to be close up to the path line of the die cutting machine; directly impressing the concave-convex areas of the picture for the first time by the die cutting machine after the cut face of the large picture is close up to the path line of the die cutting machine; delivering the large picture with a first impression into another die cutting machine or a die cutting machine of which a pressing plate is changed; performing adjustment performed according to the color code on the picture on the die cutting machine according to a second concave-convex area on the picture; and impressing the concave-convex areas for the second time after the die cutting machine is adjusted to a proper and accurate position. According to the method for processing the concave-convex areas of the picture, adjustment in an existing die cutting process is simplified into one time from two times, thus, the process can be simplified, the production efficiency is increased double, and the production cost is reduced.

Description

technical field [0001] The invention relates to a method for processing a concave-convex area of ​​a picture, which belongs to the technical field of printing industry. Background technique [0002] With the development of the printing industry, its printed products not only have the nesting and overlapping of multiple colors, but also sometimes need to make a certain area or a certain line on the picture have a concave-convex feeling. In the printing industry, it is often encountered that multiple areas on a picture need to produce a concave-convex feeling. For example, the common high-quality Baishayan needs to be processed to produce a concave-convex relief for the white crane pattern with black edges and the "White Sand Smoke" with red edges. The existing processing of the two bumps is to send the large color picture into the die-cutting machine, and pass two pick gauges in the die-cutting machine, so that the bumps and bumps are well aligned with the black track line an...
