Problems solved by technology

[0002] The existing silk screen printing technology is characterized by the use of screen as a plate and ink leakage printing, which determines that screen printing can use coarser ink particles to print various special effects on substrates that are difficult to express by other printing methods , but this feature also determines that silk screen printing cannot print fine dots like other printing methods, so in traditional screen printing, only solid bottom printing is used, and there is no dot printing like offset printing and other printing methods.

Embodiment 1

[0031] Screen printing process in the present embodiment, its steps are:

[0032] a. To make film, the printing area is set to 65% of the dots, 65 lines of lines, and an angle of 90 degrees.

[0033] b. To make a screen plate, use a 250-mesh screen to stretch the screen on the screen frame, select an oblique stretch screen with an angle of 30 degrees between the screen and the screen frame, then apply photosensitive glue, and then perform exposure, development and washing in sequence.

[0034] The step of stretching the net is to stretch the net on the screen frame with a 250-mesh screen, and then place it for more than 2 hours. After the adhesive is fully dried, remove it and seal the edge with glue;

[0035] The photosensitive glue step is to clean the above-mentioned screen plate with ordinary washing powder and water, put it in an oven to dry at 40 degrees for 1 hour, and then apply photosensitive glue on the screen plate;

[0036] The exposure and development step is to ...

Embodiment 2

[0046] Screen printing process in the present embodiment, its steps are:

[0047] 1. To make film, the printing area is set to 45% of the network dots, 50 lines of network lines, and an angle of 45 degrees.

[0048] 2. To make the screen plate, use 200-mesh screen to stretch the screen on the screen frame, select the oblique stretch screen with an angle of 20 degrees between the screen and the screen frame, then apply photosensitive glue, and then perform exposure, development and washing in sequence.

[0049] The stretching step is to use 200-mesh screen to stretch the net on the screen frame, and then place it for more than 2 hours. After the adhesive is fully dry, remove it and seal the edge with glue;

[0050] The step of applying photosensitive glue is to clean the above-mentioned screen plate with ordinary washing powder and clear water, put it in an oven to dry at 43 degrees for 1 hour, and then apply photosensitive glue on the screen plate;

[0051]The exposure and de...

Embodiment 3

[0061] Screen printing process in the present embodiment, its steps are:

[0062] 1. To make a film, the printing area is set to 55% of the network dots, 80 lines of network lines, and an angle of 90 degrees.

[0063] 2. To make the screen plate, use 400-mesh screen to stretch the screen on the screen frame, select the oblique stretch screen with an angle of 25 degrees between the screen and the screen frame, then apply photosensitive glue, and then perform exposure, development and washing in sequence.

[0064] The step of stretching the net is to stretch the net on the screen frame with a 400-mesh screen, and then place it for more than 2 hours. After the adhesive is fully dry, remove it and seal the edge with glue;

[0065] The step of applying photosensitive glue is to clean the above-mentioned screen plate with ordinary washing powder and clear water, put it in an oven to dry at 42 degrees for 1 hour, and then apply photosensitive glue on the screen plate;
