Description
Technical Field
The invention relates to the technical field of printing, in particular to a plate-free embossing process.
Background
The embossing (embossing) is a processing technology for forming embossing effect on the surface by applying pressure exceeding the elastic limit of a printing stock by using mechanical action on embossing plates, and for different embossing pattern effects, corresponding embossing plates need to be manufactured, the embossing plates can be used for a long time, and for the condition of single order style and large quantity, the embossing plates are very advantageous, but under the trend of more and less quantity of current order styles, the cost for manufacturing the embossing plates is relatively high, for example, the patent with the application number of CN201310078338.4 discloses a stereo embossing printing technology which can realize better printing effect and improve the appearance quality of the stereo embossing plates. Compared with the first printing method in the prior art, the height of the three-dimensional concave-convex patterns, particularly the convex patterns, can be improved, so that the touch feeling and the visual effect are more obvious. Compared with the second printing method in the prior art, the method does not need to use a complex metal die, reduces the manufacturing cost of the finished product, and improves the manufacturing efficiency of the finished product.
The processing technology of forming the concave-convex effect on the surface by applying the pressure exceeding the elastic limit of the printing stock under the mechanical action, and for different convex pattern effects, corresponding convex plates are required to be manufactured, the convex plates can be used for a long time, and for the condition of single order style and large quantity, the processing technology is very advantageous, but under the trend of more order styles and less quantity at present, the cost for manufacturing the convex plates is relatively high; compared with the common embossing process, the embossing process without plate embossing utilizes a paper mold to replace an aluminum plate for embossing production, in the traditional embossing production, different patterns need to be specially manufactured into different embossing plates, the manufacturing process is complex, and the positioning accuracy is not ideal due to the fact that manual positioning correction is mainly relied on during production. The paper mould used instead can be quickly manufactured by using laser die cutting, the lower mould and the upper mould can be cut out on the same piece of paper, the lower mould and the base rubber are combined and separated simultaneously during plate filling, and the different protruding depths can be quickly adjusted by increasing the thickness of the paper, so that the printing machine is convenient and quick. In addition, the convex paper die can be easily and conveniently set with positioning points, so that quick positioning is realized. The method is particularly suitable for the current trend of orders with more styles and less quantity, and the defect of paper mould: compared with an aluminum impact convex plate, the paper die is softer, the impact convex plate quality is easily affected by extrusion deformation in long-time production, and the impact convex plate needs to be replaced when a certain amount is produced, so that the adaptability to orders with a large amount is relatively poor; the paper die stamping protrusion is more suitable for products with flat stamping protrusions, and is difficult to realize for product designs with larger radians. The old method comprises the following steps: specific striking relief plates are required to be manufactured aiming at different striking relief files, and then the striking relief plates are installed on a die ironing device for production; such a striking plate can be used for a long time, and is very advantageous for the situation of single order style and large quantity, but under the trend of more order styles and small quantity at present, the cost for manufacturing the striking plate is relatively high, the alignment is completely operated manually, and the time is wasted and the accuracy is poor. The new method comprises the following steps: the paper mould is used for replacing the aluminum striking plate 1. According to the file information and the requirement, preparing the paper with the required target thickness; 2. manufacturing a laser cutting file; 3. cutting a paper mold by laser; 4. installing a paper mold; 5. testing and producing the bump; compared with the aluminum striking plate, the paper mold is simple and quick to manufacture, convenient to modify, more adhesive is suitable for orders with more styles and less quantity, and alignment is accurate. Defects: the paper mould strength aluminum-based striking plate is poor, the service life is short, and the paper mould is not suitable for orders with larger quantity.
