Problems solved by technology

The currently used DIC-TAF benzene-soluble ink process has a large deviation between the ink hue Lab value and the benzene- and ketone-free ink used by the customer, resulting in poor color reproduction; the current solvent is xylene, which is a toxic chemical reagent
[0003] Due to the difference in the hue Lab value of the two ink systems, the customer's printing cannot catch up with the effect of the concave sample of our factory, the color reproduction is not good, the rework rate is high, the printing cost increases, and the customer complaint rate is high; the volatilization rate of xylene in solvents is slow , slightly toxic, long-term inhalation of small amounts by workers into the respiratory tract will cause harm to health and the environment

Embodiment 1

[0019] A kind of ink system that is used for gravure printing, comprises the solvent that does not have benzene and ketone ink and dissolving benzene and ketone ink, and the volume ratio of benzene and ketone-free ink and solvent is 10:7, wherein, the benzene and ketone-free ink is selected from NK series are commonly used in commercially available DIC inks. The solvent is a mixture of butyl acetate and propylene glycol methyl ether, and the volume ratio of butyl acetate to propylene glycol methyl ether is 4:1. Because, the density of butyl acetate is 0.8825g / cm 3 , the relative volatilization rate is 1, and the density of propylene glycol methyl ether is 0.92g / cm 3 , the relative volatilization rate is 0.2, therefore, the density of the configured solvent is 0.87g / cm 3 , the relative volatilization rate of the solvent is 0.43, and the viscosity of the ink system is 15.5 seconds (measured in Tu-4 cups).

Embodiment 2

[0025] A kind of ink system that is used for gravure printing, comprises the solvent that dissolves benzene and ketone-free ink and benzo-ketone-free ink, and the volume ratio of benzo-ketone-free ink and solvent is 10:6, wherein, the benzo-ketone-free ink is selected from NK series are commonly used in commercially available DIC inks. The solvent is a mixture of butyl acetate and propylene glycol methyl ether, and the volume ratio of butyl acetate to propylene glycol methyl ether is 3:1. Because, the density of butyl acetate is 0.8825g / cm 3 , the relative volatilization rate is 1, and the density of propylene glycol methyl ether is 0.92g / cm 3 , the relative volatilization rate is 0.2, therefore, the density of the configured solvent is 0.86g / cm 3 , the relative volatilization rate of the solvent is 0.40, and the viscosity of the ink system is 15 seconds (measured in Tu-4 cups).

Embodiment 3

[0031] A kind of ink system that is used for gravure printing, comprises the solvent that dissolves benzene and ketone-free ink and benzene-free ketone-free ink, and the volume ratio of benzol-ketone-free ink and solvent is 10:8, wherein, benzene-free ketone-free ink is selected from NK series are commonly used in commercially available DIC inks. The solvent is a mixture of butyl acetate and propylene glycol methyl ether, and the volume ratio of butyl acetate to propylene glycol methyl ether is 5:1. Because, the density of butyl acetate is 0.8825g / cm 3 , the relative volatilization rate is 1, and the density of propylene glycol methyl ether is 0.92g / cm 3 , the relative volatilization rate is 0.2, therefore, the density of the configured solvent is 0.88g / cm 3 , the relative volatilization rate of the solvent is 0.45, and the viscosity of the ink system is 16 seconds (under coating-4 cup measurement),

Abstract

The invention relates to an ink system used for intaglio printing, and a use technology thereof. The ink system comprises a benzene and ketone free ink and a solvent for dissolving the benzene and ketone free ink, a volume ratio of the benzene and ketone free ink to the solvent is 10:(6-8), the density of the solvent is 0.86-0.88g / cm<3>, the relative volatilization rate of the solvent is 0.40-0.45, the Tu-4 cup viscosity of the ink system is 15-16s, the benzene and ketone free ink is selected from general NK series in commercial DIC inks, the solvent is a butyl acetate and propylene glycol methyl ether mixture, and a volume ratio of butyl acetate to propylene glycol methyl ether is (3-5):1. Compared with ink systems in the prior art, the ink system provided by the invention has the advantages of environmental protection, good color reduction property, high color purity, large color gamut and good smoothness.

Description

technical field [0001] The invention relates to a printing ink and its application process, in particular to an ink system for gravure printing and its application process. Background technique [0002] In the current printing industry, the DIC-TAF benzene-soluble ink process has been used, but with the advancement of technology and the country’s strict supervision of food packaging, the ink system of printing plants has gradually changed to ester-soluble inks, but the entire plate-making industry still uses benzene Soluble ink process. The currently used DIC-TAF benzene-soluble ink process has a large deviation between the ink hue Lab value and the benzene- and ketone-free ink used by the customer, resulting in poor color reproduction; the current solvent is xylene, which is a toxic chemical reagent. [0003] Due to the difference in the hue Lab value of the two ink systems, the customer's printing cannot catch up with the effect of the concave sample of our factory, the c...
