  • Detail

Some anti-counterfeiting techniques for the plate pattern on the civilian currency the design of the plate pattern is also a world within a square inch. The plate pattern is mainly composed of ground pattern, lace, round flower, relief, line splitting, anti scanning, miniature and manual carving patterns. Each part has a different function. Their functions are described in detail below

ground texture

ground texture is mainly used as a foil and foil. It generally uses light and shallow colors, and the lines are relatively sparse and thin. At a rough view, only a layer of plain and light background color can be seen. If you look closely, you can find the changes. There are several changes of ground texture:

1 Flat grain

the composition of each part is the same. By the continuous superposition and repetition of multiple elements, they are arranged according to certain rules, and then the arrangement is repeated. The flat pattern is the most common one. From an artistic point of view, the flat grain can be classified into gbt10632 (1) 989 experimental terms of metal mechanical properties from its neat and regular arrangement; Reflect the beauty of peace

2. Gradient ground pattern

ground pattern formed by transition according to certain changes. It can be divided into several patterns, such as density change, thickness change, element change, size change, etc. From the anti-counterfeiting point of view, the gradient ground pattern can play a very good anti-counterfeiting role. But it is difficult to take into account the beauty. The gradient ground pattern has only appeared in the plate pattern in recent years. It increases the difficulty in anti-counterfeiting. For counterfeiters, it is an insurmountable barrier

3. Wavy ground pattern

the ground pattern is formed by special effects such as wavy, vortex and uplift on the flat pattern. It is an extension of the flat pattern that has been served all his life. Its function is similar to that of plain grain

4. Other

radiation types are as big as a scattered one. It feels like the sky is vast. Some are sparse, some are dense, some intersect, and some are disjoint. However, no matter how many changes have taken place in the middle of each line, they all come from the outside to the inside. It has only one rule

multiple exposure type on a thin and sparse flat grain, the cloth is covered with a thick and dense flat grain, which is transparent to each other. It can be more than two layers. This is a common ground pattern on the paper money of the former Soviet Union, which played a balance between good aesthetics and strong anti-counterfeiting in the early stage. However, gravure printing is required on the second layer to achieve a good anti-counterfeiting effect. It may be that the requirements for printing are high. It is difficult to find this kind of ground pattern in recent plate works


lace is the skeleton of the pattern. It gives the whole pattern a clear vein and makes the whole pattern look sharp. It is also an important decoration in the plate pattern. The changes of lace are also divided into the following types:

single line lace

lace represented by simple lines, which plays a role in separating several components of the pattern and coordinating with the composite lace. Single line lace is generally narrow with uncomplicated lines, giving people a feeling of freshness, elegance, lightness and dexterity

composite lace

composite lace is the heavyweight in the edge where flowers bring uncertainty and risks to the macro-economy, and it is the backbone of the skeleton. The composite lace supports the whole pattern. The compound lace is often elegant and magnificent. Simple composite lace, more complex composite lace, including different types of yin and Yang figures, composite lace with thickness change, composite lace that can turn, and closed composite lace
