The stamps of thar Temple issued on May 5, 2000 have bright colors and delicate layers. It can be called a set of special stamps with high holding capacity.New Technology Of Offset Stamp Printing
Carefully observe the stamps of thar temple with a magnifying glass. The intuitive feeling is that the details of each picture of this set of stamps are very clear, accurate, complete and three-dimensional. New Technology Of Offset Stamp Printing
Take the “great golden tile hall” in Figure 2 as an example. New Technology Of Offset Stamp Printing
The gold ornaments on the roof glitter, and the dark wood carvings under the eaves, the shape and color of the wooden columns and the railings can be seen clearly. New Technology Of Offset Stamp Printing
The grains of the ornaments on the eaves of the great roof can be counted and reached out.New Technology Of Offset Stamp Printing
The wood patterns of the doors and windows under the great roof can be seen clearly on the dark side, and the green glazed tiles at the bottom are more close at hand.New Technology Of Offset Stamp Printing
Although the other three pictures of this set of stamps are not as rich and exquisite as the “dajinwa hall” in the image structure, the printing fineness is the same. New Technology Of Offset Stamp Printing
It is difficult to achieve such fineness with conventional offset printing technology, and the stamp printing of thar Temple uses a new technology of FM network thermal direct plate making, which is also the first time that such a new technology is applied to offset stamps in China.New Technology Of Offset Stamp Printing
The most prominent differences between offset FM network thermal direct plate making method and offset conventional plate making method are as follows:New Technology Of Offset Stamp Printing
Staccato FM screening technology is adopted. The dot printed by laser is square, with the characteristics of clarity and accuracy. New Technology Of Offset Stamp Printing
The fineness of the plate making dot of this set of stamps is 25 microns, which is equivalent to the conventional offset dot of about 350-400 lines / inch.New Technology Of Offset Stamp Printing
A printing plate with 4 colors directly imaged on a thermal plate making machine (1 plate for each color, 4 plates for each color).New Technology Of Offset Stamp Printing
For the plate making of conventional offset plate, first make 4 negative plates on the electronic color splitter, remake the negative plate into positive plate, and then print the positive plate onto the PS plate to make 4 printing plates. New Technology Of Offset Stamp Printing
Because in the production process, some layers are lost every time, so many layers have been lost after drying to the PS plate; and direct imaging plate making (the current plate is Kodak direct imaging thermal printing plate),.New Technology Of Offset Stamp Printing
which has no loss in level, so it can accurately and completely print the color and level of the original.New Technology Of Offset Stamp Printing
Due to the FM network thermal direct plate making technology, the printing quality is good, the color and level can exceed the quality of conventional offset printing, New Technology Of Offset Stamp Printing
And the whole batch printing quality is relatively stable, the product qualification rate is greatly improved.New Technology Of Offset Stamp Printing
The printing process and quality inspection process save labor and labor, and the production efficiency is greatly improved. New Technology Of Offset Stamp Printing
Therefore, the application of this new technology requires new investment in plate making, which seems to increase the cost. New Technology Of Offset Stamp Printing
However, due to the improvement of product quality and qualification rate, New Technology Of Offset Stamp Printing
paper and ink are saved, and the improvement of production efficiency also saves manpower and man hours, so its comprehensive cost is actually reduced rather than increased.New Technology Of Offset Stamp Printing
The dot of FM network technology is incoherent, and the overlap of square micro dots is the product of high technology. It is difficult to fake. New Technology Of Offset Stamp Printing
It itself plays an anti-counterfeiting role, not to mention other anti-counterfeiting measures.
By the way, I would like to talk about some views on the original design of thar temple. This set of stamps uses color photos to design the drawings.New Technology Of Offset Stamp Printing
In order to fully display the color photos on the stamp screen, the designer ignores the arrangement of words, especially as two of the three elements of stamps: the arrangement of national inscription and face value. New Technology Of Offset Stamp Printing
There is something wrong with the position of “China Post” in the stamp. Figures 1, 3 and 4 are placed at the lower part of the picture, which interferes with the details at the lower part of the picture, affecting the integrity of the picture. New Technology Of Offset Stamp Printing
At the same time, the words “China Post” also appear disorderly and incomplete; The “China Post China” in Figure 2 is hidden in the trees, which is not obvious. New Technology Of Offset Stamp Printing
As for the location of the face value, it should be no problem that the face values of the four stamps are placed in the sky. New Technology Of Offset Stamp Printing
However, due to the poor gold ink thickness and brightness of the offset plate, the face values in figures 3 and 4 of the stamps seem to have no spirit.New Technology Of Offset Stamp Printing
It is better to print them in dark gray, which seems to be more realistic and obvious.New Technology Of Offset Stamp Printing
