Embodiment 1

[0079] The green environmental protection printing process method comprises the following steps:

[0080] Q1 Determine the plate-making parameters: brick-type dots are used, the number of mesh lines is 22 / cm, and the plate-making depth is 100 μm;

[0081] Q2 plate making: columnar gravure is processed by laser engraving;

[0082] Q3 Trial printing: dip the ink onto the columnar gravure, and then perform trial printing and drying operations on the trial printing; judge whether it is necessary to re-prepare the ink or adjust the columnar gravure according to the obtained ink forming effect and printing quality specifications; if the ink forming effect and printing quality meet the specified printing standards, batch printing can be carried out according to the current gravure specifications and ink ratio;

[0083] Q4 printing: apply the ink on the entire plate surface of the columnar gravure, scrape off the excess ink on the surface of the columnar intaglio with a doctor blade ...

Embodiment 2

[0101] It is basically the same as Example 1, the only difference is:

[0102] The preparation method of described modified alkyd resin is:

[0103] D1 Mix 3 parts by weight of sulfonamide, 7 parts by weight of cellulose, and 18 parts by weight of ether, and then treat it at 85°C with an ultrasonic wave with a power of 350W and a frequency of 36kHz for 170min. Dry the filter residue for 8 hours at lower temperature to obtain modified cellulose;

[0104] D2 Mix the alkyd resin, the modified cellulose, acid anhydride, and anti-aging agent in a mass ratio of 65:22:8:2, then blend at 105°C for 105min at a speed of 800rpm, and extrude the particle size through an extruder 1mm blank;

[0105] D3 crushing the blank and passing it through a 2000 mesh screen to obtain the modified alkyd resin.

[0106] The sulfonamide is a mixture of N-methyl-N-nitroso-p-toluenesulfonamide and p-aminotoluene-o-sulfonanilide in a mass ratio of 3:2.

[0107] The cellulose is a mixture of cyanoethyl c...

Embodiment 3

[0111] It is basically the same as Example 1, the only difference is:

[0112] The preparation method of described modified alkyd resin is:

[0113] D1 Mix 3 parts by weight of sulfonamide, 7 parts by weight of cellulose, and 18 parts by weight of ether, and then treat it at 85°C with an ultrasonic wave with a power of 350W and a frequency of 36kHz for 170min. Dry the filter residue for 8 hours at lower temperature to obtain modified cellulose;

[0114] D2 Mix the alkyd resin, the modified cellulose, acid anhydride, and anti-aging agent in a mass ratio of 65:22:8:2, then blend at 105°C for 105min at a speed of 800rpm, and extrude the particle size through an extruder 1mm blank;

[0115] D3 crushing the blank and passing it through a 2000 mesh screen to obtain the modified alkyd resin.

[0116] The sulfonamide is a mixture of N-methyl-N-nitroso-p-toluenesulfonamide and p-aminotoluene-o-sulfonanilide in a mass ratio of 3:2.

[0117] The cellulose is a mixture of cyanoethyl c...

Abstract

The invention discloses a green and environment-friendly printing process method. The green and environment-friendly printing process method comprises the following steps of Q1, platemaking parameter determining; Q2, platemaking; Q3, trial printing; and Q4, printing. Printing ink is smeared on the whole plate face of a columnar intaglio plate, redundant printing ink on the surface layer of the columnar intaglio plate is scraped away through a doctor blade, then a printed object is placed on the plate face of the columnar intaglio plate, and then pressure is applied to print the printing ink on the columnar intaglio plate onto the printed object. The print of the printed object prepared by the process method is durable and non-sticky.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a green environmental protection printing process. Background technique [0002] The printing industry is a system industry with a long history and a large scale. Since the invention of printing in ancient China, the quantity and quality of printed books have been constantly improving with the improvement of the times and the level of science and technology. And it is with the development of the times and the level of science and technology that more and more industries and biochemical fields need to use various fine new printing technologies that can meet various stringent requirements. Nowadays, printing technology is not only a traditional technology that only serves physical books. In modern life, whether it is advertisements, posters, or various stylistic promotional products, even ceramics, wood, metal and other products Inside, all have become the scope involved in the ...
