Best printing skills reduce costs

  • Detail

Editor's note: in the plate printing process, a pattern plate is often used to print the background color once, such as securities, trademarks, decorative prints, etc. These products have different specifications and printing numbers, but the shading plates are often universal. Therefore, it is of positive significance to preserve the old printing plate for reuse and give full play to its maximum efficiency, which will improve economic benefits and enhance the vitality of embossing

due to the limited quantity and specifications of some products, it is often necessary to use small-size paper for printing, and it is completely unnecessary to make a shading plate with a corresponding size of printing format, because there are old versions that can be used. Some printing houses often cut the 8-plate into 9-kai or 12 Kai, or even smaller format for printing. Although this is more cost-effective for the time being, it can avoid the trouble of making a new version, but the old small version can no longer print a large version, so we have to make a new version of a large version. Therefore, adopting the "plate cutting method" to realize large page printing and small format will increase the production cost and cause unnecessary economic waste

in view of this situation, through deep exploration and practice, the traditional production mode has been changed, and the printing process technology of "large version and small printing" has been innovated and improved, which can not only keep the specifications of the old shading plate unchanged, but also effectively save money. When the format of the transfer is smaller than the original specification, the necessary "strain" measures can be taken, so that the excess layout will not be stained with ink or contact with the packaging lining, so as to ensure normal printing and receive good printing effect

according to the theoretical concept and practical results of "three levels" of printing, the level of printing layout is the basic requirement to accept uniform inking and meet uniform printing pressure. Then, for the thin solid resin version with soft texture, as long as the "routine" is broken in the pad link in the sticking version, the excess edge of the version can be sunken, and the inking of the inking roller will not be obtained, and there will be no imprint marks, which will not cause damage to the packaging lining. As long as the height of the page to be printed is properly padded, uniform inking can be obtained, which meets the normal stamping conditions. It can be seen that the idea of breaking the condition of printing plate leveling in printing "three leveling" can be extended from the principle of printing "three leveling", which provides a theoretical and practical basis for the implementation of "large plate and small print" process of abnormal printing. Based on the above ideas, the idea of implementing the new process of "large version and small printing" without cutting plates came into being. Through bold practice, initial results were achieved in production

if the size of the printing plate (shading plate) is 39cm × 26cm should be printed on the 8-open (format) of 27cm × 18cm so that scientists can obtain information products about the response of cells to different 3D printing scaffolds through a large number of experiments. In order to keep the original format intact, cut a 26cm piece first when loading the version × 18cm 35og/m white board paper, stick it with the corresponding area of double-sided tape at the appropriate place on the back of the 8-open shading plate (the vertical and horizontal two global 3D printing crazes can only be aligned without reducing the edge), and then use 39cm × The 27cm double-sided adhesive tape directly binds the back of the whole printing plate (including the white board part) to the plate holder, and then compresses and sticks it firmly. This is 26cm × The 18cm size of the layout is significantly higher than the non printing layout due to the extra white board and a layer of adhesive tape, so it can ensure the normal inking and embossing of the printing layout. The non padded layout is slightly lower, so it is not inked, and there is a certain gap with the lining surface, and it does not damage the lining, which can meet the printing conditions and requirements of "large version and small printing". He gave up the work of the world's top 500 researchers. Due to the thin resin plate texture, he is working hard with oems1 to develop more soft and elastic materials. Through the pad difference, the purpose of adjusting the height of the page is achieved, and the conditions required for printing are achieved. In this way, we can use the "big size" old storage plate to print all kinds of small size products, so as to achieve multi-purpose, flexible and convenient, and greatly improve the utilization rate of the printing plate

for many years, the general shading plates of various specifications have been printed by the printing method of "large plate and small print" without cutting plates, which saves the plate making time, shortens the production cycle, and significantly improves the production efficiency and economic benefits. Because the process is simple, the operation is fast, and the printing effect is good, it has won customers' satisfaction
