Industry & Occupation
Classification
Summary
A manufacturing technician who prepares and manufactures emulsions used in photosensitive materials such as photographic films and printing paper, and performs quality control.
Description
Emulsion Worker (Photographic Sensitizing Materials) is a specialist who manufactures milky photosensitive emulsions used in photographic films and printing paper. Raw materials such as silver halide compounds and dispersants are mixed and dispersed in prescribed ratios, and fine crystals are controlled through processes such as emulsification, precipitation, and washing. Process conditions such as temperature, pH, and viscosity are strictly managed to ensure the uniformity and sensitivity of the final product. Work is also performed in cleanroom environments, quality tests using analytical instruments, and production is advanced while complying with safety, health, and environmental regulations.
Future Outlook
Due to the decline in demand for photographic film from digitalization, the number of practitioners is on a decreasing trend, but high value-added special photosensitive materials will continue to be demanded in niche markets. Technology succession is a challenge due to the retirement of skilled technicians.
