Introduction

The Automatic Film Developing and Fixing Machine is a professional film processing equipment designed for high-quality film development applications in screen printing, pad printing, plate making, and graphic production industries. The machine automatically completes the complete film processing cycle, including film developing, film fixing, film washing, and film drying, ensuring stable film quality and accurate image reproduction. After UV exposure, the film is loaded into the automatic film processor and transported through each processing section by a precision conveying system. During the film developing process, the developer chemically reacts with the exposed photosensitive silver halide layer, converting it into visible silver particles to form the required image pattern. Precise control of developing time, chemical concentration, and temperature is essential for achieving accurate film density, image contrast, and fine detail reproduction, which directly affects the quality of subsequent screen printing plate making. After development, the film enters the film fixing process, where the fixing solution removes the remaining unexposed silver halide materials and permanently stabilizes the developed image. High-quality film fixing ensures that the image will not continue to react with chemicals or environmental conditions, improving film durability and maintaining consistent exposure performance during plate production. The film washing process follows fixing to thoroughly remove residual developer, fixer, and other chemical substances from the film surface. Effective washing is critical for preventing chemical contamination, maintaining film transparency and dimensional stability, and ensuring reliable image transfer for screen printing and pad printing plate preparation. Finally, the processed film enters the film drying system, where hot air drying or heated roller drying technology quickly removes moisture from the film surface. Uniform film drying helps prevent deformation, water marks, and surface damage, ensuring the film remains flat, clean, and ready for storage or immediate use. With precise control of film developing, film fixing, film washing, and film drying procedures, the Microcomputer Film Processor provides excellent film density consistency, sharp image quality, and stable processing performance. It is an ideal Film Processor for Screen Printing and Pad Printing Industry, helping manufacturers achieve high-precision film output for professional plate-making applications.

Development principle:

After exposure, the film enters the developing section of the Automatic Film Developing and Fixing Machine, where the developer chemically reacts with the exposed photosensitive layer on the film. The exposed areas are converted into visible image patterns, gradually forming clear black or colored images. During this film developing process, accurate control of developing time, chemical concentration, and temperature is essential to achieve proper film density, image contrast, and detail reproduction. The unexposed areas of the film have little or no reaction with the developer, allowing the photosensitive material to remain unchanged until the fixing stage. After development, the film enters the film fixing section, where the fixer removes the remaining unexposed photosensitive materials and permanently stabilizes the developed image. This film fixing process ensures that the image will not be affected by further chemical reactions or environmental conditions, providing long-term image stability. After fixing, the film proceeds to the film washing process, where residual developer, fixer, and other chemical substances are thoroughly removed from the film surface. Effective washing is important for maintaining film cleanliness, transparency, and dimensional stability, ensuring accurate image transfer during screen printing and pad printing plate making. Finally, the film enters the film drying system, where hot air or heated rollers quickly remove moisture and residual water from the film surface. Proper film drying helps prevent deformation, stains, and surface damage, producing a clean, flat, and stable film ready for storage or further printing applications. Through precise control of film developing, film fixing, film washing, and film drying, the Microcomputer Film Processor delivers high-quality films with consistent density, sharp images, and reliable performance, making it an ideal film processing solution for screen printing and pad printing industries.

Basic structure

Chemical Tank System: The machine is equipped with multiple processing tanks for developer, fixer, and washing water. Each tank features a circulation system to maintain uniform chemical concentration and temperature, ensuring stable film developing, fixing, and washing quality.
Film Conveying System: Driven by motors, rollers, and gears, the precision conveying system accurately controls film speed and position through each processing stage. It ensures sufficient processing time in the chemical tanks and drying section for consistent image quality and reliable results.
Drying System: The film processor provides two drying methods: hot air drying and heated drum drying. Hot air drying uses a fan to evenly blow heated air onto the film surface, while heated drum drying transfers heat through direct contact with the heated roller, ensuring efficient and uniform film drying.
Intelligent Control System: The control system precisely manages key parameters including processing temperature, developing and fixing time, conveying speed, and drying temperature. Operators can manually adjust settings or select preset processing programs for different film types, ensuring stable and high-quality film output.

How to operate the film developing machine?

Preparation--Check the film developer to confirm whether the developer's drive roller, nozzle, temperature control system, and drying device are operating normally, and whether there is any blockage, wear or leakage. Configure the developer, fixer, etc. according to the process requirements to ensure that the concentration and temperature meet the standards (such as the developer temperature usually needs to be controlled at 20-25°C.
Operation process--Put the film into the film inlet steadily to avoid wrinkles, skewness, cards or uneven development; if it is batch processing, pay attention to the interval between films to ensure smooth transmission. Observe the development time, temperature, speed and other parameters in real time, and strictly follow the process standards.
Liquid management and maintenance--Replace the liquid medicine regularly: Replace the developer and fixer in time according to the frequency of use and the degree of contamination to avoid aging of the liquid medicine and affect the clarity of the image.
Inspection and maintenance--The working area of the developer should be well ventilated to prevent the accumulation of chemical gases; waste liquid should be collected and treated according to environmental protection standards and should not be discharged at will.
