Problems solved by technology

Gravure printing technicians know that the darker the plate, the easier the printed appearance will be. The viscosity of the printing ink must be increased, and the increase in the viscosity of the printing ink will result in poor leveling of the printing microscopic ink layer and unevenness. However, the microscopic printing quality, customers It will not be raised, and the printing factory will not control it as a quality monitoring point, causing frequent white spots on subsequent composite aluminum-plated products, and in serious cases, it will cause batch scrapping

Embodiment 1

[0012] Embodiment 1 is a preferred embodiment of the present invention. In this embodiment, the printing sample is full plate yellow. When making a plate, the plate making process is determined to be 80 lines / cm, and the engraving knife is 130 degrees. When printing, the yellow plate ink 3# Zaen cup 13 seconds, the printing appearance meets the requirements of the sample, and the composite is made of water-based adhesive or solvent-free composite, and the appearance is excellent. The actual test quality and benefit indicators are shown in Table 1.

Embodiment 2

[0013] Embodiment 2, in the present embodiment, the printing sample draft is full version yellow, when plate making, the plate making process is determined as 80 lines / cm, engraving knife 120 degree engraving knife, during printing, yellow version ink 3# Zahn cup 14 seconds , the printing appearance meets the requirements of the sample, and the water-based adhesive or solvent-free composite is used for lamination and has an excellent appearance. The actual test quality and benefit indicators are shown in Table 1.

Embodiment 3

[0014] Embodiment 3, in the present embodiment, the printing sample draft is a full version of yellow, when plate making, the plate making process is determined to be 80 lines / cm, carving knife 135 degree carving knife, when printing, yellow version ink 3# Zahn cup 12 seconds , the printing appearance meets the requirements of the sample, and the water-based adhesive or solvent-free composite is used for lamination and has an excellent appearance. The actual test quality and benefit indicators are shown in Table 1.

[0015] After the application of the invention, the product quality can be stably ensured, the consumption of ink and composite adhesive can be reduced, the discharge of VOCs can be reduced, and the production efficiency can be improved. The actual test performance is shown in Table 1.

Abstract

The invention relates to a flexible packaging process belonging to the field of flexible packaging. Specifically, according to the color characteristic of a printed layout, when all light colors or colors which can be added with white ink or a diluent are used for plate-making, the printing ink carrying amount of a plate roller is decreased, and the viscosity of printing ink is controlled to be minimized according to the color reduction condition during printing. According to the flexible packaging process, the consumption of the printing ink is reduced, the problem of formation of composite spots in flexible packaging is solved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a flexible packaging process, in particular to a gravure printing process suitable for flexible packaging compounding, especially suitable for flexible packaging compounded aluminized products, belonging to the field of flexible packaging. Background technique [0002] Composite spots are a common problem in the field of flexible packaging lamination, especially in the field of composite aluminum plating. Composite spots are most likely to appear in light-colored ink. Ordinary technicians only solve the compound spot problem from the compound field. The usual solution is to increase the amount of glue applied or reduce the compound production speed. These two solutions not only greatly increase the consumption of adhesives, but also greatly reduce production efficiency. . [0003] After a lot of tests and analysis, those skilled in the art have determined that the root cause of the spot problem in the field of composite alumin...
