How to print text on a small paper box

When prin, that prepared ink is pour into one side of the screen printing plate, and a certain pressure is exerted on the ink part of the screen printing plate by use the screen printing squeegee, and at the same time, the ink evenly moves to the other side of the screen printing plate. During the movement, the ink is scraped from the grid of the graphic part and squeezed onto the substrate.

Because of the viscosity of the ink, the imprint is fixed in a certain range. In the printing process, the scraper is always in contact with the screen printing board and the substrate line, and the contact line moves with the movement of the scraper. Because there is a certain gap between the screen printing plate and the substrate, the screen printing plate reacts to the scraper through its own tension, which is called resilience.

Due to elasticity, the screen printing plate and the substrate are only in movable line contact, while other parts of the screen printing plate are not in contact with the substrate. Make ink and screen break, ensure printing size accuracy and avoid rubbing the substrate.

When the scraper is lifted after scraping the whole page, the screen printing plate is also lifted, and the ink is gently scraped back to the original position. This is a printed stroke. Then take down the printed product and replace it with another product for printing.

Basic requirements of screen printing

1, weaving smoothly. Prevent white leakage and ink accumulation.

2, good wear resistance.

3, to have a higher tensile strength.

4. There should be a structure suitable for the substrate and printed image, such as the number of items.

5. Through hole rate and screen thickness.

6, to have the ability to resist chemical effects such as ink, detergent.

7. It should be flexible to ensure that it can be restored after each printing.

8. The expansion rate after contact with water should be as small as possible to ensure the stability of printing plate size.

9, with a variety of screen photosensitive materials have good adhesion.
