There are many editions of banknote printing , and most of them use a combination of flat, concave, and convex editions for printing. Most of its printing technologies are used, such as wiring printing, offset printing, double-sided printing, pattern to line and other special printing technologies. What do these printing methods and technologies mean? Lithography: Developed from the early lithography, because of its unique personality in plate making and printing, as well as extremely simple work and low cost, it has been continuously researched and improved by experts in modern times, and has become the most used in printing today. method. In terms of its feel, the ticket face feels smooth and has no unevenness. Gravure printing: The mold for gravure printing is carved from a steel plate, and the lines on the mold are concave. When printing, the ink in the lines is transferred to the paper, forming patterns and patterns that protrude from the paper surface, and the three-dimensional sense is very strong. Because the engraving of the steel plate is very difficult and difficult to imitate, gravure printing is often used for printed products with high anti-counterfeiting requirements such as banknotes and certificates. Touch with fingers, there is a strong sense of unevenness. Toppan Printing: Letterpress printing is just the opposite of intaglio printing. The inked part of the printing plate is convex, and the pattern on the printing plate is higher than the surface. During printing, after the ink is applied to the pattern, the paper is pressed and the ink is transferred from the printing plate to the paper surface. . This printing method is called "relief printing". Due to the difference in plate-making process and materials used, it is divided into movable type, electroformed version, planographic version, and rubber version. Toppan printing products have the characteristics of neat lines and strong brushstrokes. Now everyone's letterpress printing on coins is not really a "relief" or "relief". The real "relief printing" process currently cannot generally print complex graphics, and can only be used to print serial numbers on banknotes. Many people say that the three-version banknotes have "relief", which is actually "gravure printing". Offset printing: This is a relatively advanced printing technology, that is, using several colors of ink on the basis of one-time overprint, and then using several colors to overprint, thus forming a variety of colors. This type of printing is generally used for decorative patterns on small squares. For example, a small square was printed with blue flowers, and then printed with red, it became purple-red. If the small squares of several colors are overprinted, they look colorful and dazzling. This technique of overprinting should have a higher accuracy. Double printing: When printing banknotes, the front and back sides are accurate to the printing rules, which is also a relatively high printing technology. This method is currently limited to offset and letterpress printing. There are 3 types: (1) The colored edge line or the four peripheral lines of the front part of the banknote coincide with the edge line at the same position on the back side. (2) Align a certain part in the bottom line, for example, printed with small circles, triangles and other patterns, align on both sides. (3) Portrait printing process is complex and technical requirements are higher, such as French franc. Pattern alignment: This is a new process of shading printing. One is full-page printing (up, down, left, and right) printed to the side. If the two ends are butted together, the colorful xuan patterns or other shapes can be printed.
