A plotter-like multi-feed workflow
The Tricolor head is best understood as several independently controlled spray channels. It does not mix colors inside one nozzle like an inkjet printer.
The challenge
Some applications require more than one liquid or color without manually changing reservoirs between paths.
The setup
The Tricolor head uses three separate nozzles/channels, controlled as part of the machine workflow. This lets the program choose between feeds as the path is executed.
The result
The video demonstrates the Tricolor principle. It is useful for explaining multi-channel capability, while also making the physical size and working-area tradeoff clear.
Why this matters
Tricolor is useful when separate feeds are part of the process. It is not compatible with Tilt, and the useful working area is reduced because all nozzles need physical clearance.
