Several common printing processes in the packaging printing process:

1. Covering film: also known as "over molding", "laminating", "film pasting", etc. Covering film is a transparent plastic film that is hot pressed onto the surface of printed materials to protect and increase gloss. At the same time, the colors of graphics and text are more vivid, and it also plays a role in waterproofing and anti fouling. It can be divided into two parts: surface processing and molding processing for hot stamping. Film covering has been widely used for surface binding and protection of book covers, picture books, commemorative albums, postcards, product manuals, calendars, maps, etc.

2. Hot stamping and silver stamping: Hot stamping is a common printing and decoration technique, also known as "hot stamping"; Hot stamping "; The production principle is to heat the metal printing plate, apply foil, and press gold text or patterns onto the printed material. Hot stamping is similar to hot stamping, but the materials used are different. Hot stamping will present a golden luster, while hot stamping will present a silver luster. The characteristics of hot stamping and silver stamping: clear and beautiful patterns, bright and eye-catching colors, often used for logo printing.

3. UV printing: It is a printing process that uses ultraviolet light to dry and cure ink, and is one of the most important printing processes in the printing industry. Its characteristics: It can increase the glossiness and artistic effect of the product, and better highlight the subtle layers and contours of the graphic and textual parts.

4. Concave convex embossing: Using a convex template (male template) to imprint a three-dimensional relief pattern on the surface of a printed material through pressure (the printed material is partially raised, giving it a three-dimensional effect and creating a visual impact), which is called embossing; Concatenation is achieved through the use of concave templates (female templates) through pressure. Its characteristics are: it has a clear sense of relief, which can increase the three-dimensional and artistic appeal of printed materials.
