1.Offset Printing is an indirect printing method characterized by the graphic and non graphic parts of the printing plate being on the same plane. By using the principle of oil-water separation, ink is only attached to the graphic and textual parts, and then transferred to the substrate through rubber.
2. Inkjet Printing: Inkjet printing is an efficient and flexible printing method that does not require plate making, plate drying, or repeated color matching, and is suitable for various materials. Inkjet printers can be divided into two types: black and white inkjet and color inkjet. This printing method has no pressure or printing plate, making it very convenient.
3.Packaging Printing is mainly used for printing on various packaging materials to add decorative patterns and graphic characters. Packaging printing can not only convey information, but also enhance the attractiveness of products, thereby increasing sales. The methods of brushing include letterpress printing, flatbed printing, gravure printing, screen printing, and orifice plate printing.
4. Label Printing: Label printing covers various printing methods, mainly including relief printing, offset printing, flexographic printing, and screen printing. In order to achieve the most exquisite label effect, it is necessary to cleverly combine various techniques and fully utilize the advantages of various methods during the printing process.
5. Anti counterfeiting printing is a printing technology with special functions that uses printing methods to prevent unauthorized imitation, copying, or forgery. Anti counterfeiting printing includes anti-counterfeiting design and plate making, precision printing equipment, and matching elements such as ink and paper, which together constitute an effective anti-counterfeiting system.
6. Metal Printing
Metal printing is a method of printing on metal substrates, typically used for packaging high-end products such as luxury boxes and canned foods. Domestic metal printing mainly adopts methods such as offset printing, transfer printing, screen printing, and flexographic printing.
7. Hot Stamping: The commonly used hot stamping techniques are gold or silver stamping, and various colors and styles can be selected according to the design requirements of the book. The hot stamping process utilizes the principle of hot press transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate, forming a special metallic effect.
8. Lamination process
The film coating process has strong protective properties, protecting printed colors from scratches and enhancing the toughness of printed products. According to the different materials of the film, it can be divided into glossy film, matte film, pearl film, tactile film, etc. The surface of the book cover after lamination is smooth and shiny.
9. Embossing process
The embossing process uses patterned molds to deform the paper under certain pressure and temperature, forming certain patterns, thus performing artistic processing on the surface of the paper. Embossing presents patterns or textures of varying depths on the surface of materials.
10. Spot UV Coating UV technology uses UV ink to cover the surface of printed materials, producing different bright effects. Apply UV varnish to the prominent parts of the cover to make the glossy pattern bright, shiny, and three-dimensional.
11. Debossing process uses concave and convex molds to perform artistic processing on the surface of printed materials. Applying pressure from the front of the paper to make the surface concave is called indentation, which increases the stereoscopic visual experience and good tactile sensation
12. Embossing process: Embossing process applies pressure from the back of the paper to make the surface bulge, forming a raised effect, which is one of the commonly used techniques in post printing processes.
13. Die Cutting is a technique that uses a combination of a die-cutting knife and a wire cutting knife in the same template to perform shape hollowing on materials. Printed materials or other paper products can be cut according to pre designed shapes, so that the shape of printed materials is no longer limited to straight edges and right angles.
14. Laser Cutting: Laser cutting utilizes the high energy density characteristics of laser to irradiate the surface of the product, cutting through the processed product and producing a certain hollow pattern effect.
The above are some common types of printing processes in the printing industry, each with its unique advantages and applicable scenarios. Choosing the appropriate printing process according to specific needs can achieve the best printing effect.
