Overview

The Automatic Film Developing and Fixing Machine is a professional microcomputer film processor specially designed for screen printing and pad printing plate making applications. It integrates automatic developing, fixing, washing, and drying functions to provide precise and consistent film processing results. In the traditional printing process, film density control is a critical factor that directly affects image contrast, exposure accuracy, and plate-making quality. An unstable film density may lead to insufficient or excessive exposure during screen plate production, resulting in unclear details, poor reproduction, and reduced printing accuracy. This advanced film developing and fixing machine adopts intelligent microcomputer control technology to accurately manage developing time, chemical concentration, and processing temperature, ensuring stable film density and uniform image quality. As a reliable film processor for pad printing and screen printing industry, it produces high-density, high-contrast films that are ideal for precision screen exposure, pad printing plate preparation, packaging printing, and specialty printing applications.

Development principle:

After UV exposure, the printing film enters the developing section of the Automatic Film Developing and Fixing Machine, where the photosensitive layer on the film undergoes a controlled chemical reaction with the developer solution. The exposed photosensitive material is converted into a visible image, forming clear black or colored patterns according to the original artwork. During this process, precise control of developing time, chemical concentration, and temperature is essential for maintaining consistent film density and image contrast, which directly influence the accuracy of subsequent plate making. The unexposed areas of the film do not react significantly with the developer, allowing the original photosensitive material to remain unchanged until the fixing process. After development, the film is automatically transferred into the fixing tank of the Microcomputer Film Processor, where the fixer removes the remaining unexposed photosensitive materials and stabilizes the developed image. This fixing process ensures that the film pattern remains permanent and resistant to further chemical reactions or environmental influences. After fixing, the film enters the washing and drying stages, where residual chemicals are thoroughly removed and moisture is eliminated. The drying system of the automatic film processor machine ensures a clean, flat, and stable film surface, making it ready for storage or direct use in screen printing plate making and pad printing plate preparation. Through precise control of the developing, fixing, washing, and drying procedures, the Film Processor for Pad Printing and Screen Printing Industry delivers high-quality films with excellent density consistency, sharp image details, and reliable dimensional stability. This makes it an essential piece of equipment for professional printing applications requiring accurate image transfer and high-precision plate production.

Equipment and materials required for a small film output center:

Most pad printing, silk screen printing and hot stamping processing companies can outsource film output business to professional film output centers, saving unnecessary funds and technical reserves. When your company has a certain scale and must establish its own film output center, you can refer to the following suggestions:

Image input equipment--Scanner and Digital camera.
Computer and related software--High-performance computer:
Film output equipment--Outputs image information from the computer to film, and is the core equipment of the film output center

Basic structure

Chemical Processing Tank System:
The chemical processing section of the Automatic Film Developing and Fixing Machine consists of multiple independent tanks, including developer, fixer, and washing water tanks. Each tank is designed to provide stable chemical treatment during the film processing cycle. An integrated circulation system maintains uniform chemical concentration and temperature distribution, ensuring consistent developing performance, accurate film density control, and reliable image quality.
Precision Film Conveying System:
The conveying system is driven by high-precision motors, rollers, and transmission gears to smoothly transport the film through each processing stage. It accurately controls the film movement speed and positioning inside the chemical tanks and drying section, ensuring sufficient processing time for developing, fixing, washing, and drying. This stable conveying process helps prevent film deformation and guarantees consistent processing results.
Efficient Drying System:
The drying section of the Microcomputer Film Processor provides two optional drying methods: hot air drying and heated drum drying. Hot air drying uses a fan to distribute heated air evenly across the film surface, while heated drum drying transfers heat directly through contact with the heated roller surface. Both methods effectively remove residual moisture and chemical substances, producing clean, dry, and stable films ready for plate making.
Intelligent Control System:
Equipped with an advanced control system, the film developing and fixing machine enables precise adjustment of key processing parameters, including developing temperature, fixing time, conveying speed, washing duration, and drying temperature. Operators can manually set processing parameters or select preset programs for different film types, ensuring flexible operation and consistent results. The intelligent control system makes this equipment an ideal film processor for screen printing and pad printing industry, supporting high-precision film production for professional plate-making applications.

Function principle

Flushing principle: Film processor realizes flushing based on the chemical reaction between chemical agents and photosensitive materials on the surface of film. After the film is exposed, the chemical composition of its photosensitive layer changes. Chemical solutions with different functions in the film processor act on the film in turn, and the latent image formed by exposure is converted into a stable and visible image through chemical processes such as development and fixing. For example, the developer reduces the silver halide in the exposed part to silver, and the fixer removes the unexposed silver halide, thereby fixing the image.
Drying principle: The washed film is quickly dried through a hot air circulation system or a heating roller to avoid residual water stains affecting the image quality.
