Production technology of environment-friendly anti-counterfeiting scintillating blue pearlescent ink

Abstract

The invention provides a production technology of an environment-friendly anti-counterfeiting scintillating blue pearlescent ink. The technology includes the steps of: 1) stirring a scintillating bluepearlescent pigment with ink 30min before printing; 2) adding an environment-friendly mixed solvent, performing stirring for 15min, then detecting the ink viscosity and controlling the viscosity range at 28-32s of No.4 cup, at the same time adding an anti-settling agent with a mass ratio of no more than 3%, and performing stirring; 3) in the production process, detecting the ink viscosity every other 15-20min, and controlling the viscosity in the range of 28-32s of No.4 cup; 4) during printing preparation, using 80-line anilox roller and installing a new scraper; 5) before formal printing andeach halt printing, cleaning a rubber blanket with the environment-friendly mixed solvent; and 6) during production, detecting the ink viscosity every other 15-20min, and controlling the viscosity inthe range of 30-32s of No.4 cup. After printing by the technology, a packaging product has significant scintillating blue pearlescent effect, the ink has good stability on machine, the technology canadapt high speed machine stable production, also can combine with commonly used solvent medium easily, is convenient to operate, and does not bring pollution.

Description

【Technical field】 [0001] The invention relates to an ink printing process on offset printing, in particular to a production process of an environment-friendly anti-counterfeit flashing blue pearl ink. 【Background technique】 [0002] In recent years, green printing has become the main theme of the development of the industry. Among them, water-based ink is favored by more and more printing companies because of its safety, harmlessness, and environmental protection, and its application fields are becoming more and more extensive. [0003] The printing process of pearlescent printing is basically the same as that of traditional water-based ink printing. Pearlescent printing is a new type of special glossy printing that has been popular in packaging and anti-counterfeiting printing in recent years. Transparent ink, silver glitter refracts through the ink layer to produce a pearlescent effect like pearl luster. This kind of printed matter has two major characteristics: one is th...

Problems solved by technology

However, there are also certain disadvantages in offset printing and glazing group printing. During the use of ink, it is easy to accumulate blankets and the squeegee is easy to wear, which will lead to changes in printing effects, and the continuous and stable quality of printing cannot be guaranteed.

[0005] Therefore, in the existing flashing blue pearlescent printing process, pearlescent ink is prone to precipitation, resulting in viscosity changes and accumulation of blankets, resulting in changes in printing machine parameters. It is not suitable for high-speed printing. In terms of the stability of the production process and its printing suitability, it is difficult It is difficult to achieve both environmental protection and stable production at high printing speeds, and there is an urgent need to improve the printing process of existing flashing blue pearlescent inks
