Telephone card printing "we attach great importance to the research of anti-counterfeiting printing technology." Engaged in anti-counterfeiting printing for many years, we have our own unique views on the printing process of anti-counterfeiting printed materials such as scratch cards, variable tickets, anti-counterfeiting vouchers, etc.
In the scraping card printing and other printed materials will often use the plate printing process, the following will introduce the plate printing knowledge below.
In the plate printing process, a pattern plate is often used to print a background color, such as securities, trademarks, decoration printed materials, etc. The specifications of these products vary, and the number of prints varies greatly, but shading plates can often be used. Therefore, whether the old plate can be preserved to the maximum extent, continue to make full use of it, and give full play to its maximum efficiency, which has a positive role in improving economic efficiency and enhancing the vitality of embossing.
Xingzheng anti-counterfeiting printing technicians found that due to the limitation of the quantity and specification of some products, small size paper is often used for printing. It is not necessary to make a shading plate of corresponding size. Because of the old version can be used, but some printing manufacturers often cut the octave plate into nine open format printing or twelve page printing, 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. However, if you want to print a large page next time, the old small page will not be able to reprint the large page. It can be seen that using "cutting plate method" to achieve large page printing and small format printing will inevitably lead to the increase of production cost and unnecessary economic waste.
In view of this situation, technical personnel through in-depth exploration and practice, a change in the traditional mode of production. The printing technology of "large plate and small print" has been innovated and improved, so as to keep the specifications of old shading plates intact and save money effectively. When the size of the printing plate is less than that of the original printing ink, the printing effect can be reduced to normal.
The technical personnel also said that according to the theoretical concept of printing "three levels" and the practical results, the printing plate flatness is the basic requirement to accept uniform ink brushing and meet the uniform printing pressure. Then, the soft thin solid resin plate, as long as the "routine" is broken in the pad link in the gluing plate, the surplus plate edge can be sunken, and the ink roller can not be brushed, and the imprint mark will not be produced, which will not damage the packaging lining. Take scraping card as an example, as long as the height of the page is properly padded, the ink can be evenly brushed to meet the normal printing conditions. It can be seen that from the principle of "three flat" printing, we can extend the assumption of breaking the condition of "three flat" in printing, thus providing theoretical and practical basis for the implementation of abnormal printing "large plate and small printing". Based on the above ideas, the idea of implementing the new process of "large printing and small printing" without cutting the plate has been put into effect in the production.
It can also be used in scraping card printing. For example, on the 8K format with 39 × 27cm plate (shading plate), 18K products with 26 × 18cm should be printed. In order to keep the original format completely, a piece of 350g white board paper with 26 × 18cm specification should be cut first, and then it should be glued to the appropriate place on the back of 8K shading plate with corresponding area of double-sided adhesive tape (the two sides of vertical and horizontal alignment can be aligned), and then the back of the whole printing plate (including the white pad part) and the plate holder can be directly bonded with 39 × 27cm double-sided adhesive tape, and then it is pressed and bonded tightly. As a result, an extra layer of paper can be obtained at this part of the printing plate, which is obviously higher than that of the offset sheet. However, the layout without pad is a little lower, so it can not get brush ink, there is a certain gap between the pad and the surface of the lining, and does not damage the outer lining, so it can meet the printing conditions and requirements of "large printing and small printing". Due to the soft and elastic texture of the thin resin plate, the height of the plate can be adjusted through the difference between the pad plates, and the conditions required for printing are realized. In this way, we can use "large size" old storage plate to print various small size products, and realize the multi-purpose of one page, which can be large or small, flexible and convenient, and greatly improve the utilization rate of printing plate.
Xingzheng anti-counterfeiting printing technicians can realize "big plate and small print" printing without cutting the plate every time when printing various specifications of general shading plates. This not only saves a lot of plate making time, but also greatly shortens the production cycle, and improves the production efficiency and economic benefits. Especially because of its simple process, fast operation and good printing effect, it has won the customer's satisfaction. In particular, its main products: scraping card production, anti-counterfeiting ticket printing, anti-counterfeiting coupons production and other valuable securities production and printing, in the industry leading level, won the recognition of the majority of businesses.
