Printing skills, reducing costs
In the printing process, a pattern is often used to print a base color, such as securities, trademarks, and decorative prints. These products vary in size and print numbers, but shading plates are often versatile. Therefore, it is of positive significance to preserve the old printing plate for reuse and to exert its maximum efficiency, which is to improve economic efficiency and enhance the vitality of embossing.
Due to the number and specifications of some products, it is often necessary to use small-size paper for printing, and it is completely unnecessary to re-create a shading version of the corresponding size of the printing format, because the old version can be used. Some printers often cut the 8 bottom plate into 9 or 12 or even smaller prints. Although this is more cost-effective, it can save the trouble of making a new version. However, the old small layout can no longer print a large layout, so I have to make a new version of the large layout. Therefore, the use of the "cutting method" to achieve large-format printing of a large format will inevitably increase production costs and cause unnecessary economic waste.
In response to this situation, through the exploration and practice of deep people, the traditional production methods have been changed, and the printing process technology of the "big print" has been innovated and improved, which not only keeps the old shading specifications unchanged. And effectively saved money. When the transfer is smaller than the original size of the film, the necessary "strain" measures can be used to make the excess layout free of ink and contact with the liner, ensuring normal printing and good printing results.
According to the theoretical concept of printing "Sanping" and the practical results, the printing layout is the basic requirement for accepting uniform ink and satisfying uniform printing pressure. Then, the soft solid resin plate with soft texture can break the "conventional" on the stencil link in the stencil, so that the excess stencil can be recessed, and the ink of the ink roller can not be obtained, and no embossing marks are produced. , does not cause damage to the packaging lining. For the printing layout, as long as the layout is suitable, the ink can be evenly distributed to meet the normal printing conditions. It can be seen that from the principle of printing "Sanping", it is possible to extend the idea of breaking the condition of printing plate in the printing of "Sanping", thus providing theoretical and practical implementation for the realization of the process of printing "big print". in accordance with. Based on the above ideas, the idea of implementing a new process of “big print” is realized, and through bold practice, it has achieved initial results in production.
For example, a product of 26 cm × 18 cm is printed on an 8-open (web) of a plate (shading plate) having a size of 39 cm × 27 cm. In order to completely maintain the original format, when installing the plate, first cut a piece of 35Og/m white paper of 26cm × 18cm size, and stick it with the double-sided tape of the corresponding area on the back of the 8-open pattern (both and horizontal) The edges can be aligned. Then, the back surface of the entire printing plate (including the white plate portion of the pad) is directly bonded to the plate with a double-sided tape of 39 cm × 27 cm, and then pressed tightly. In this way, in the layout of the 26cm×18cm web, due to the multi-padding of a whiteboard paper and a layer of tape, it is obviously higher than the non-printing layout part, so that the printing layout can be normally inked and embossed. The unpadded layout is slightly lower, so there is no ink, and there is a certain gap with the surface of the lining, and the outer lining is not damaged, which can meet the printing conditions and requirements of the "big print". Due to the soft and elastic texture of the thin resin plate, the difference in the thickness of the plate is achieved, and the conditions required for printing are achieved. In this way, it is possible to use the old version of the "large specification" to print various small-sized products, realize a multi-purpose version, be flexible and convenient, and greatly improve the utilization rate of the printing plate.
Over the years, the use of uncut version of the "big print" printing method to print a variety of general-purpose shading patterns, saving plate making time, shortening the production cycle, significantly improving production efficiency and economic efficiency. Because of the simple process, fast operation and good printing effect, it has won customer satisfaction.
