Problems solved by technology

This is because the plastic film substrate is a non-absorbent material. In the actual production process, it is difficult to make the printed pattern firmly attached to the carrier, and there will be no anti-sticking or falling off; and the general ink drying speed is more suitable for Printing at a printing speed of 50-120m / min, during the continuous printing process of film blowing machines and printing machines, the conventional ink drying speed is too fast to carry out subsequent printing operations; at the same time, when the above ink drying speed meets the production needs Under certain conditions, the ink must also be completely cured within a certain period of time in order to realize the industrial production of plastic film printing.

Embodiment 1

[0083] Embodiment 1 of the present invention provides a kind of low-speed continuous water-based ink printing process, comprises the following steps:

[0084] Step 1. Adjust the printing machine: ①Put the bag on the film blowing machine and the printing machine according to the bag threading procedure; ②Before the power of the printing machine is turned on, set the lifting mode of the plate roller gear and the take-off wheel to automatic, and the plate roller gear lift switch Set it to rise; ③Set the ink wheel of the C / D two-color printing seat to front printing, and then turn on the blower to preheat for 10 minutes for use.

[0085] Step 2. Extracting the film: ① Adjust the height of the ink tank poured into the ink, so that the ink can touch the ink wheel evenly, and fix it on the printing machine; ② Fix the printing plate on the printing machine by adhesive connection, and the printing plate The four sides are fixed with tape; ③ Adjust the speed of the main machine so that ...

Abstract

The invention discloses a low-speed continuous water-based ink printing process. By adopting a screen roller with a specific mesh number, matching an atomizer, and a suitable printing speed, and using a specific ink, the printed matter obtained by printing has no graphics and text Unclear, edge burrs and anti-adhesive phenomena. At the same time, the printed pattern also has excellent composite properties such as extremely high gloss, coloring rate and flatness, and the printing ink layer has extremely high adhesion to the substrate. In addition, the reagents used in the printing process of the present invention are all safe and environmentally friendly reagents, which reduce the release of organic solvents and solve the environmental pollution and personnel health problems caused by solvent-based inks. It is a green and environmentally friendly printing process. It can be used in large-scale production.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a low-speed continuous water-based ink printing process. Background technique [0002] As people's awareness of environmental protection increases day by day, the printing industry dominated by solvent-based inks is facing new choices and challenges. Due to the high content of aromatic compounds such as toluene, benzene or xylene in solvent-based inks, the emission of volatile organic compounds (VOC) exceeds the standard, which not only damages the personal safety of staff and residents, but also pollutes the environment. [0003] At present, vigorously promoting water-based ink printing has become an important link in promoting the green printing industry. However, most of the current water-based inks use paper as the substrate, and plastic film printing is still rarely involved. This is because the plastic film substrate is a non-absorbent material. In the actual production ...
