Embodiment 1

[0021] A silk screen printing process capable of avoiding printing heterogeneity and unevenness, comprising the following steps:

[0022] Step 1. Soak the squeegee knife and ink return knife in the electroplating solution: put the squeegee knife and ink return knife to be used for printing into the pre-prepared electroplating solution and soak for 5 minutes; the electroplating solution is polytetrafluoroethylene;

[0023] Step 2. Drying: Dry the squeegee knife and ink return knife soaked in step 1; in this embodiment, the drying method is to use a hair dryer to dry the squeegee knife and ink return knife. In this embodiment, Use a hair dryer to dry the squeegee and ink return knife for 6 minutes;

[0024] Step 3. Install the squeegee and ink return knife: Install the dried squeegee and ink return knife on the printing machine;

[0025] Step 4. Start the printing machine: start the printing machine, and use the squeegee knife and the ink return knife to print.

Embodiment 2

[0027] A silk screen printing process capable of avoiding printing heterogeneity and unevenness, comprising the following steps:

[0028] Step 1. Soak the squeegee knife and ink return knife in the electroplating solution: put the squeegee knife and ink return knife to be used for printing into the pre-prepared electroplating solution and soak for 3 minutes; the electroplating solution is polytetrafluoroethylene;

[0029] Step 2. Drying: Dry the squeegee knife and ink return knife soaked in step 1; in this embodiment, the drying method is to use a hair dryer to dry the squeegee knife and ink return knife. In this embodiment, It takes 4 minutes to dry the squeegee and ink return knife with a hair dryer;

[0030] Step 3. Install the squeegee and ink return knife: Install the dried squeegee and ink return knife on the printing machine;

[0031] Step 4. Start the printing machine: start the printing machine, and use the squeegee knife and the ink return knife to print.

Embodiment 3

[0033] A silk screen printing process capable of avoiding printing heterogeneity and unevenness, comprising the following steps:

[0034] Step 1. Soak the squeegee knife and ink return knife in the electroplating solution: put the squeegee knife and ink return knife to be used for printing into the pre-prepared electroplating solution and soak for 8 minutes; the electroplating solution is polytetrafluoroethylene;

[0035] Step 2. Drying: Dry the squeegee knife and ink return knife soaked in step 1; in this embodiment, the drying method is to use a hair dryer to dry the squeegee knife and ink return knife. In this embodiment, Use a hair dryer to dry the scraper knife and the ink return knife for 8 minutes;

[0036] Step 3. Install the squeegee and ink return knife: Install the dried squeegee and ink return knife on the printing machine;

[0037] Step 4. Start the printing machine: start the printing machine, and use the squeegee knife and the ink return knife to print.

Abstract

The invention relates to the technical field of silk screen production, in particular to a silk screen process capable of avoiding printing color differences and nonuniformity. The silk screen processcapable of avoiding printing color differences and nonuniformity comprises the following steps that firstly, a doctor knife and an ink return knife are soaked in electroplating liquid; secondly, drying is carried out; thirdly, the doctor knife and the ink return knife are mounted; and fourthly, a printer is started. Due to the fact that the doctor knife and the ink return knife are placed into the electroplating liquid to be soaked before printing, then the doctor knife and the ink return knife are used for printing after being dried, and micropores in the surfaces of the doctor knife and theink return knife are filled with the electroplating liquid, the situation that ink is left in the micropores in the surfaces of the doctor knife and the ink return knife and is hard to clear can be avoided in the printing process, the situation of color differences can be prevented from happening to printed products in the next printing procedure, and then the quality of the printed products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of screen printing production, in particular to a screen printing process capable of avoiding uneven printing color. Background technique [0002] The glass cover of the touch panel requires multiple silk screen printing processes, for example, IR area printing and alignment printing are required. In the process of printing ink, a squeegee knife and an ink return knife are usually used for printing. Since the types and colors of inks used in different printing processes will be different, and after a printing process is completed, ink will remain on the squeegee knife and the ink return knife. Once the ink is cured, it will be difficult to remove. This is because there are micropores on the surface of the squeegee and the ink return knife, that is, the surface is uneven. During the process of scraping the ink, the ink is easy to adhere to the micropores on the surface of the squeegee and the ink return knif...
