Embossing Overview

Embossing, also known as pressure embossing, is a special processing technique in the surface decoration of printed materials. It uses concave-convex molds to cause plastic deformation of the printed substrate under a certain pressure, thereby artistically processing the printed surface. . The various embossed graphics and patterns embossed show different patterns of depth and depth, have a sense of relief, and enhance the print's three-dimensional and artistic appeal.

Embossing and embossing is the transplantation and application of embossed art in printing. Its printing plate is similar to the arching method used in the woodblock watermark in China.

When printing, the ink is directly used by the pressure of the printing machine without using ink, and the method of operation is the same as that of general relief printing, but the pressure is higher. If the quality requirements are high, or if the paper is relatively thick and the hardness is relatively large, it is also possible to use hot pressing, that is, to apply current to the metal master of the printing press.

The embossing and stamping process has a long history of application and development in China. As early as the beginning of the 20th century, hand-engraved printing plates and manual embossing processes were produced; in the 40's, hand-engraved printing plates and mechanical embossing processes were developed; in the 50-60s, an independent system was basically formed.
In recent years, the development trend of high-grade and multi-variety products in prints, especially packaging and decorating products, has promoted more and more popularization and improvement of embossing and imprinting processes. The production of printing plates and embossing and imprinting equipment are gradually being semi-automated and fully automated. In foreign countries, automatic printing and embossing and imprinting production lines including multi-color printing units have been realized.

The embossing and embossing process is mostly used in the post-processing of printed materials and paper containers, such as packaging cartons, decorating bottles, trademarks, and bookbinding, calendars, and greeting cards. The packaging and decoration utilizes the embossing and embossing process, and the combination of depth and shallowness and the combination of thickness and artistic expression methods make the appearance of packaging products more perfect in art.

The embossing and embossing process includes the operations of printing plates, embossing, finishing and packaging.
