The functions and characteristics of embossing:

Convex embossing, also known as embossing printing, is a special processing technology in the surface decoration processing of printed matter. It uses convex and convex molds. Under a certain pressure, the printed base material is plastically deformed, thereby performing artistic processing on the surface of the printed matter. The various embossed convex graphics and patterns show different shades of patterns and have an obvious sense of relief, which enhances the three-dimensional sense and artistic appeal of the printed matter.

Concave-convex embossing is the transplantation and application of relief art in printing. Its printing plate is similar to the arching method used in woodblock watermarking in my country.

When printing, no ink is used but the pressure of the printing machine is directly used for imprinting. The operation method is the same as that of general letterpress printing, but the pressure is higher. If the quality requirements are high, or the paper is thicker and harder, hot pressing can also be used, that is, electric current is connected to the metal base of the printing machine.

Application and development:

The concave and convex embossing process is mostly used in the post-processing of printed matter and paper containers, such as packaging cartons and decoration. Bottle labels, trademarks, book bindings, calendars, greeting cards, etc.

Packaging and decoration use concave and convex embossing technology, and use the artistic expression method of combining dark and light, thick and thin, so that the appearance of packaging products can be more perfectly reflected artistically. The embossing process includes the production of printing plates, embossing, sorting and packaging, etc.

Gravure printing:

Suitable for printing high-quality and expensive prints. Whether it is color or black and white pictures, the gravure printing effect can be comparable to that of photography. Because the plate making cost is expensive and the printing volume must be large, it is also a less commonly used method. Suitable for printing securities, stocks, gift certificates, certificates of commercial reputation or stationery, etc.

Technology is developing rapidly, and today we can directly output on the media through computers using some of the above printing methods. The maturity of electrostatic imaging and laser technology enables "printing on demand" with high quality requirements in small batches.
