Common processes for printing

Common processes for printing
First, the packaging and printing process

1. Design: According to the product characteristics and market demand, enter
Row packaging structure, pattern, text and other design.
2. Plate making: make the design draft into a printed version, which is common
Plate-making methods include offset printing, gravure printing, flexo printing, etc.
3. Printing: Use a printing press to transfer the ink to the packaging
In terms of materials, common printing methods include lithography,
Gravure printing, flexographic printing, screen printing, etc.
4. Post-press processing: surface treatment of printed matter,
To improve aesthetics and functionality, common processes include lamination, hot stamping, UV, embossing, die-cutting, etc.

2. Commonly used materials for packaging and printing
Paper: white cardboard, coated paper, kraft paper, etc
It is used to make cartons, paper bags, etc.
Plastics: PE, PP, PET, etc., used to make plastic bags, bottles, etc.
Metals: aluminum, iron, etc., used to make cans, metal cans, etc.
Glass: used to make glass bottles, glass jars, etc. Composite materials: composed of two or more materials, such as paper-plastic composite, aluminum-plastic composite, etc.

3. Common processes of packaging and printing
Offset printing: high printing precision, good color reproduction, suitable
High-volume printing.
Gravure printing: The ink layer is thick and the colors are bright, which is suitable for printing large areas of color blocks and metallic colors.
Flexo printing: The use of flexographic plates, suitable for printing plastic film, paper and other materials.
Silk screen printing: the ink layer is thick, the three-dimensional sense is strong, and it is suitable for printing irregular surfaces and special effects.
Digital printing: no plate-making, suitable for small batches, personalized printing.

Fourth, packaging and printing quality control

Color: Control color accuracy with tools such as color swatches, density meters, and more.
Overprint: Control the accuracy of the overprint between different color plates to avoid misalignment.
Ink layer: Control the thickness of the ink layer to avoid being too thick or too thin.
Surface treatment: control the quality of laminating, hot stamping and other processes to ensure aesthetics and functionality.
Finished product inspection: inspection of the appearance, size, function and other aspects of the finished product.

Fifth, the development trend of packaging and printing

Green environmental protection: use environmentally friendly materials and processes to reduce pollution.
Intelligent: Application of automation equipment and digital technology
to improve efficiency and quality.
Personalization: Meet the individual needs of consumers and provide customized services.
Anti-counterfeiting: apply anti-counterfeiting technology to protect the rights and interests of brands and consumers.
