Pad plate screen plate UV exposure machine

Pad plate screen UV exposure machine:

Pad plate

• Definition and principle: The pad plate is a key component in the pad printing process. It is usually a metal plate (such as a steel plate) with the required pattern or text etched or laser engraved on the surface. When printing, first apply the ink on the pad plate, and then transfer the ink to the surface of the object through the rubber head.

• Application scenario: Commonly used for printing on irregular shaped surfaces, such as plastic toys, electronic product shells, etc.

Screen plate

• Definition and principle: The screen plate consists of a screen frame and a screen. The screen is tightly stretched on the screen frame, and a pattern leak area is formed on the screen through photosensitive glue or other blocking materials. When printing, the ink passes through the leak area to the surface of the object.

• Application scenario: Widely used in clothing printing, circuit board printing, glass printing and other fields, such as pattern printing on T-shirts.

Offset plate

• Definition and principle: Offset plate is generally an aluminum plate base, and the surface is treated and coated with a photosensitive layer. Through exposure, development and other processes, oleophilic and hydrophilic areas are formed, and printing is performed using the principle of oil-water incompatibility.

• Application scenarios: Mainly used for paper printing, such as printing of books, magazines, posters, etc.

Hot stamping plate

• Definition and principle: Hot stamping plate is usually made of copper or zinc alloy, and raised patterns or texts are produced through engraving or etching processes. During hot stamping, the metal foil layer of hot stamping paper is transferred to the surface of the object under high temperature and pressure.

• Application scenarios: Commonly used in high-end packaging, greeting cards, book covers, etc., to increase the beauty and texture of the product.

UV exposure machine

• Definition and principle: UV exposure machine uses ultraviolet rays (UV) to irradiate printing plates (such as offset printing plates, screens, etc.) coated with photosensitive materials, so that the photosensitive materials undergo photochemical reactions, thereby forming the desired pattern. It is mainly composed of a light source, an exposure platform, a control system, etc.

• Application scenarios: It is an important equipment for making printing plates and is widely used in the printing industry to ensure the accuracy and quality of printing plates.

 In the process of making the screen, it is a very important process to transfer the pattern on the film to the screen printing plate coated with photosensitive adhesive, which is done by the printing machine. The working table of the plate printing machine is transparent glass, and the glass is under the UV lamp tube. When printing the plate, the plate negative film is attached to the screen surface and placed on the table, and the blanket will only press the negative film and the screen plate tightly. , Since the printing negative has black graphic area and transparent area, UV light will pass through the transparent area and be blocked by the graphic area, and the photosensitive adhesive on the screen will appear in exposed and non-exposed areas, and then in the process of processing to make the final Net version.
