What is Photo Etching?
Photo etching is a process used to create intricate designs and patterns on metal surfaces. It involves using a light-sensitive material called a “photoresist” to transfer an image onto the metal.
How Does Photo Etching Work?
- Image Preparation: Photo Etching: The desired image is created digitally and converted into a film negative.
- Photoresist Application: Photo Etching A thin layer of photoresist is applied to the metal surface.
- Image Exposure: Photo Etching: The photoresist-coated metal is exposed to light through the film negative. The exposed areas of the photoresist harden, while the unexposed areas remain soft.
- Chemical Etching: Photo Etching:The metal is then placed in a chemical bath that etches away the exposed areas, leaving behind the desired image or pattern.
- Photoresist Removal: Finally, the remaining photoresist is removed, revealing the etched design.
