New technology for offset ticket printing

The "Tal Si Temple" stamp, issued on May 5, 2000, is a colorful and delicate layer and is considered to be a set of special stamps with superior holding capacity. Using a magnifying glass to carefully observe the "Tar Temple" stamp, the intuitive feeling is that the details of each set of stamps are very clear, accurate, complete, and particularly strong in three-dimensional. Take the Dajinwa Temple in Figure 2 as an example. The gold ornament on the roof glitters. The shadows and colors of the wood carvings and columns under the eaves and the trunks are all vivid. The number of wooden patterns on the doors and windows below the large roof can be seen clearly, even on the dark side, and the green glazed tile at the bottom is more like a footstep.The other three charts of this set of stamps are not large in the image structure. The Golden Palace is so rich and colorful, but the delicateness of printing is the same. Delicateness like this is difficult to achieve with conventional offset printing technology. The printing of stamps on the Ta'er Temple is based on the new technique of direct thermal plate making by the FM network and is the first application of such a new technique for Chinese offset stamps.

The most prominent differences between offset thermal network direct thermal plate method and conventional offset printing method are the following aspects:

1. Using inconsecutive frequency modulation screening technology (staccato fm screening), the laser dots are square, with clear and precise features. The fineness of this set of stamps is 25 micrometers, equivalent to about 350-400 lines/inch for conventional offset dots.

2. Directly imaging 4 colors on a heat-sensitive platemaking machine as a set of fish (1 plate per color, 4 plates into 4 plates). The traditional offset plate making, first made in the electronic color machine 4 negative film version, from the negative film version into a positive version, and then the positive version of the print version to make 4 fish on the PS version. Because in the production process, each copy is always lost some levels, so after drying to the PS version has lost a lot of levels; and direct imaging plate (the current version of the material is Kodak direct imaging thermal fishing), at the level There is no loss, so the color and level of the original can be printed accurately and completely.

3, because the FM network thermal direct plate making technology printing quality, color, level can exceed the quality of conventional offset printing, and its entire batch printing quality is relatively stable, the product pass rate has greatly improved, the printing process and quality inspection procedures for the Labor and labor are saved, and production efficiency is also greatly improved. Therefore, the application of this new technology, although it requires a new investment in platemaking, seems to increase the cost, but due to the improvement of product quality, the pass rate is increased, paper and ink are saved, and the increase in production efficiency also saves manpower and man hours. Its overall cost is actually a decrease rather than an increase.

4. The network of FM network technology is the overlap of inconsistent square micro-points. It is a product of high technology and it is difficult to fake. It has a security effect in itself. Not to mention there are other anti-counterfeiting measures.

By the way, I would like to talk a bit about the original design of the Ta'er Temple. This set of stamps uses color photographs to design the artwork. The designer ignores the arrangement of the text in order to display the full-color photo on the stamp sheet. As the two elements of the stamps, the two elements of Guoming and denomination are arranged. The position of China Post in the postage stamps is somewhat inappropriate. The first, third, and fourth figures are all placed on the lower part of the screen, which interferes with the details of the lower part of the screen and affects the integrity of the picture. At the same time, the words "China Post China" appear to be The disorder is not complete; while China Post's China Post 2 is hidden in the trees, it is not obvious. Regarding the position of the face value, the denominations of the original 4 stamps were all placed in the sky. It should be no problem, but The thickness and brightness of the offset gold ink are relatively poor. Therefore, the denominations of the 3rd and 4th drawings of the stamps appear to be indifferent. It is better to use a dark gray seal, which seems to be more real and obvious.

This article is to introduce new technologies for offset printing. A point of view on manuscript design is only for design reference.
