What is CI flexographic printing
Satellite flexographic printer is a high-precision printing equipment that adopts a central impression cylinder structure. It is mainly used for soft packaging, corrugated paper pre printing, and label printing. It can adapt to mass production of materials such as paper, plastic film, metal foil, etc., and has a market share of about 70% in Europe and America. Its core advantages lie in a printing accuracy of ± 0.075 millimeters, a printing speed of up to 600 meters per minute, and the use of a closed dual scraper ink delivery system and laser engraved metal ceramic mesh rollers to achieve precise ink volume control. This device achieves rapid plate changing through gearless direct drive technology, equipped with an automatic tension control system and intelligent temperature control module, and supports multi-color printing, glazing, and die-cutting composite processes to be completed in one go. Domestic applications are concentrated in the fields of cardboard pre printing and plastic flexible packaging. Enterprises such as Xi'an Aerospace Huayang and Wenzhou Changhong have launched domestic models with a width of 1.62 meters and a speed of 450 meters per minute, but high-end equipment still relies on imported core components [1] [3]. The combination of environmentally friendly water-based ink and flexible resin plate material combines low cost and low pollution characteristics, and future technological upgrades will further expand the market share of domestic equipment.
Characteristics of Flexographic Printing
1. Low investment, quick returns, and high returns. The price of flexographic printing machines is much lower than gravure printing machines and offset printing machines of the same color group, and it integrates printing, die-cutting, and glazing, achieving multiple processes in one go without the need to purchase additional post-processing equipment, with a high return on investment. 2. The device has a simple structure and easy operation. The simplified structure of the flexographic printing machine makes it easy to operate and improves production efficiency. 3. High production efficiency. Flexographic printing uses roll materials, which can achieve double-sided printing and complete processes such as line polishing, hot stamping, die-cutting, waste disposal, and winding, shortening the production cycle, saving manpower, material resources, and financial resources, reducing production costs, and improving economic benefits. 4. Widely available printing materials. Flexographic printing has a wide range of applications, including paper, plastic film, aluminum foil, adhesive paper, etc. 5. The quality of printed materials is excellent. The printing accuracy reaches 150 lines/inch, with vivid colors, rich layers, and excellent visual effects, suitable for packaging printing needs. 6. Strong environmental performance. Using water-based or solvent based ink, non-toxic and harmless, in line with green production standards, suitable for food packaging. 7. The economic benefits are significant. The combination of flexographic printing machines and post press equipment shortens the production cycle and reduces costs. Flexographic printing costs only 10% -20% of gravure printing, reduces ink consumption by 1/3, saves 40% energy, and has a scrap rate of less than 1% -2%, far lower than gravure and offset printing, effectively reducing production costs.
The difference in application between flexographic printing and offset printing
There are some differences in the application of flexographic printing and offset printing: Different materials: Flexographic printing is suitable for printing materials such as film, paper, cardboard, etc., while offset printing is suitable for printing high-quality printed materials such as books, magazines, packaging boxes, etc. Different color quantities: Flexographic printing has a faster printing speed, but its requirements for color quantity and color reproduction are not as high as offset printing. Offset printing can accurately reproduce multiple colors and achieve high-quality printing effects. Different scope of application: Flexographic printing is suitable for printing large and printed products, such as food packaging bags, medical packaging bags, and plastic bags. Offset printing is suitable for printing small and long cycle products, such as books, magazines, picture books, and high-quality packaging boxes. Cost difference: Flexographic printing is usually more cost-effective than offset printing because the equipment and material costs for flexographic printing are relatively lower. However, offset printing can achieve better printing results, so in some cases it may be considered as a more advanced printing method. There are also some differences in the use of ink between flexographic printing and offset printing: Different types of ink: The ink used in flexographic printing is usually water-based ink with better leveling performance, which can better adapt to flexible plates with better elasticity, while the ink used in offset printing is usually oil-based ink with higher viscosity, which can better adapt to plates with higher hardness. Ink viscosity is different: flexographic printing has lower ink viscosity and requires higher printing pressure to achieve printing effect, while offset printing has higher ink viscosity and can achieve printing effect with smaller printing pressure. Ink adhesion is different: water-based ink for flexographic printing has lower adhesion, especially when printing non absorbent substrates that require additional treatment such as corona discharge, while oil-based ink for offset printing has higher adhesion and requires additional treatment. Generally, flexographic printing can be printed on both corrugated paper and flexible packaging, while offset printing is usually applied to corrugated paper box packaging
The difference between flexographic printing and regular printing machines
Traditional printing machines use rigid printing plates (such as offset printing plates and gravure printing plates), which transfer graphics and text through mechanical pressure. The ink transfer path is from the printing plate to the blanket and then to the substrate.
