The dam through setting up has restricted the flow area who drops into printing ink, and the input of printing ink can the visual control to make and extrude printing ink backward flow and reuse, avoid extruding the long-time static condition of printing ink, keep the mobility of printing ink, improved the utilization ratio of printing ink, reduce the waste of printing ink, reduce manufacturing cost.)

1. A method of saving printing ink, characterized by: the method comprises the following steps:

s1, arranging a dam in the screen, wherein the dam consists of four frictioning, the four frictioning are fixed into a matrix through a high-viscosity transparent adhesive tape, the area outside the dam in the screen is an outer area, and the area inside the matrix covers a window and a scraper;

s2, after the glue scraping is well fixed, high-viscosity transparent adhesive tapes are pasted on the four right angles, the bottom edge gap of the dam is stuck by the high-viscosity transparent adhesive tapes on the inner side of the dam, and the bottom edge gap of the dam is completely blocked;

s3, forming an ink area in the dam, and after the ink is scraped by a scraper, extruding the ink to the dams at two ends to form ink accumulation with a certain width;

and S4, the dam has a certain thickness, ink with a certain width is accumulated and reflows to the windowing along with the height difference, and after the use of the screen printing plate is finished each time, the dam is removed by tearing the high-viscosity transparent adhesive tape and is cleaned with the screen printing plate at the same time for recycling.

2. A method of saving printing ink as claimed in claim 1, wherein: the scraper is a short-length scraper, and a 45-degree right-angled isosceles triangle notch is formed in the scraper.

Technical Field

The invention relates to the technical field of ink printing, in particular to a method for saving printing ink.

Background

Along with the development of electronic industry, the industry upgrading pace is accelerated, electronic products become an indispensable part of people in daily study, work, life and other aspects, the use field of the electronic products is increased, the demand of COF products is increased day by day, and the printing stock printing is carried out after an ink printing process in a COF flexible circuit board is mixed and stirred with a diluent according to the characteristics of ink and the need of the ink according to a certain proportion, so that the viscosity of the ink is reduced, the ink is thinned, the flowing performance is increased, and the thinner ink thickness required by customers is achieved.

The ink is a uniform mixture composed of color bodies, bonding materials, fillers, additives and the like; printing can be carried out, and drying is carried out on the printed body; is a colored pasty adhesive with certain fluidity. Therefore, the color, the body bone and the drying performance are the three most important performances of the ink, and the ink has various types, different physical properties and thick and sticky performances; some are quite thin, and some are made of vegetable oil as a binder; some of them use resin and solvent or water as a binder, and these are determined according to the object of printing, i.e., the substrate, the printing method, the type of printing plate, the drying method, and the like.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a method for saving printing ink, and solves the problems of high production cost caused by the waste of a large amount of printing ink.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: a method of saving printing ink comprising the steps of:

s1, arranging a dam in the screen, wherein the dam consists of four frictioning, the four frictioning are fixed into a matrix through a high-viscosity transparent adhesive tape, the area outside the dam in the screen is an outer area, and the area inside the matrix covers a window and a scraper;

s2, after the glue scraping is well fixed, high-viscosity transparent adhesive tapes are pasted on the four right angles, the bottom edge gap of the dam is stuck by the high-viscosity transparent adhesive tapes on the inner side of the dam, and the bottom edge gap of the dam is completely blocked;

s3, forming an ink area in the dam, and after the ink is scraped by a scraper, extruding the ink to the dams at two ends to form ink accumulation with a certain width;

and S4, the dam has a certain thickness, ink with a certain width is accumulated and reflows to the windowing along with the height difference, and after the use of the screen printing plate is finished each time, the dam is removed by tearing the high-viscosity transparent adhesive tape and is cleaned with the screen printing plate at the same time for recycling.

Preferably, the scraper is a short-ruler scraper, and a 45-degree right-angled isosceles triangle gap is formed in the scraper.

(III) advantageous effects

The invention provides a method for saving printing ink. The method has the following beneficial effects:

1. according to the method for saving the printing ink, the flowing area of the printing ink is limited through the arranged dam, the input amount of the printing ink is visually controlled, the extrusion printing ink is enabled to flow back and be repeatedly used, the long-time static condition of the extrusion printing ink is avoided, the fluidity of the printing ink is kept, the utilization rate of the printing ink is improved, the waste of the printing ink is reduced, and the production cost is reduced.

2. According to the method for saving printing ink, the frictioning dam is adhered with the screen printing plate by using the high-viscosity adhesive tape, the manufacturing is easy, and the frictioning dam can be detached for repeated use after being used.
