Screen printing consists of five major components, namely screen plates, squeegees, inks, printing stations, and substrates. The basic principle of screen printing is to use the basic principle of the screen printing part of the mesh to penetrate the ink, the non-image part of the mesh is not transparent to the printing. The ink is poured on one end of the screen printing plate during printing, and a certain pressure is applied to the ink portion on the screen printing plate by the squeegee blade while moving toward the other end of the screen printing plate. The ink is squeezed from the mesh of the graphic portion onto the substrate by the squeegee during movement. Due to the viscous action of the ink, the imprint is fixed within a certain range. During the printing process, the squeegee is always in line contact with the screen printing plate and the substrate, and the contact line moves with the movement of the squeegee due to the screen printing plate and the substrate. A certain gap is maintained between them, so that the screen printing plate at the time of printing generates a reaction force against the squeegee by its own tension, and this reaction force is called a resilience force. Due to the resilience, the screen printing plate and the substrate are only in a moving line contact, and the other portions of the screen printing plate are separated from the substrate. The ink and the screen are broken and the printing is ensured to ensure the dimensional accuracy and avoid the dirty substrate. When the squeegee scrapes across the entire layout, it is lifted, and the screen plate is lifted, and the ink is gently scraped back to the original position. This is a printing trip.
Embroidery is a general term for various decorative patterns that are stitched on fabrics. Embroidery is divided into two types: silk embroidery and feather embroidery. It is to use a needle to puncture the thread or other fibers and yarns on the embroidery with a certain pattern and color, and to form a decorative fabric with the embroidery. It is an art of adding people’s design and production to any existing fabric with needles and threads. Embroidery is one of the traditional Chinese handicrafts, with at least two or three thousand years of history in China.
