How are gobos made?
Gobos are made using precise manufacturing processes that turn a design into a physical stencil for light. The exact method depends on the material, but most gobos fall into two main categories: metal (steel) and glass.
1. It starts with a design
Every gobo begins as artwork—usually a logo, text, or pattern—created as a high-contrast graphic. This design determines how light will pass through (or be blocked).
2. The material is selected
The design is then matched to the right material:
- Steel gobos – best for simple, bold designs
- Glass gobos – used for detailed images, shading, or full color
3. The gobo is manufactured
The production process depends on the material:
Steel Gobos
- Made from thin sheets of stainless steel
- The design is cut out using a high-precision laser (or sometimes chemical etching)
- The cut-out areas are where light will pass through
Glass Gobos
- Made from heat-resistant optical glass
- The design is etched, engraved, or printed onto the glass surface
- Advanced methods allow for fine detail, gradients, and even full-color
4. Final finishing and sizing
Once created, gobos are:
- Cut to exact sizes to fit specific lighting fixtures
- Inspected for clarity and durability
- Mounted in holders or frames for use in lights
