Photosensitive Emulsion
Photosensitive emulsion is a light-sensitive coating applied to a surface, typically used in screen printing and photography to develop images.
In screen printing, the emulsion is applied to a mesh screen and exposed to light, hardening the areas that are light-exposed and leaving the unexposed areas soft. The soft areas can then be washed out, creating a stencil on the screen for ink to pass through. In photography, photosensitive emulsion is used in traditional film processes to capture images. This technology paved the way for modern photographic techniques and remains a staple in various artistic and industrial applications.
