The exquisite packaging is also inseparable from packaging printing. Packaging printing is an important means and way to improve the added value of commodities, enhance the competitiveness of commodities and open up the market. To print a good packaging paper printing process, the designer should know the necessary packaging printing process knowledge, so that the designed packaging works have more functionality and aesthetics.
There are many exquisite techniques in the printing process of packaging paper products, which are divided into:
The expression of stamping process is to make the pattern of stamping or silver stamping into a convex plate for heating, and then place the aluminum foil paper of the required color on the printed matter. After pressurizing, the aluminum foil is attached to the printed matter. Tip: there are many kinds of bronzing paper materials, including gold, silver, laser silver, black, red, green and so on.
Laminating process, laminating process is a kind of surface processing technology after printing, which is a product processing technology formed by covering a layer of transparent plastic film on the surface of printed matter with laminating machine. A relief print is one in which the back of the paper is slightly raised, the edges of the lines or dots are neat, and the ink appears light in the center.
Gravure printing and letterpress printing, on the contrary, the graphic part of the printing plate is lower than the non graphic part. Forming a groove. The ink is only covered in the groove, and the plate and the paper are pressurized to transfer the ink from the concave part of the plate to the paper. Gravure printing products have the advantages of thick ink layer, bright color, high printing resistance, stable quality and fast printing speed, so they are widely used in practice. Tip: the surface of the coated printed matter will be smoother, brighter, stain resistant, water resistant and wear-resistant.
In addition to the above several printing processes, the product packaging printing process also includes refraction, die-cutting indentation, hydrothermal transfer, drop molding, ice flower, scraping silver and other printing processes. With the continuous improvement of people's living standard and commodity packaging automation, higher requirements are not only put forward for packaging paper printing process. To adapt to the new changes in the market and meet the requirements of different customers, we can improve the printing process of packaging paper.
