Dye-Sublimation Ribbon Testing

High-speed spectral process control for thermal-transfer ribbon.

Spectrometer-based inline process control for CMYK thermal-transfer ribbon manufacture — capturing hundreds of spectra a second, synchronised to the moving film, to monitor ink-deposit density.

Using the unique capabilities of our spectrometer to synchronise spectrum capture to the high-speed motion of a film on a production line, we were able to help a major chemical manufacturer to control the process for manufacturing their CMYK thermal transfer ribbons. Taking hundreds of spectra a second, the density of ink deposited on the film could be monitored continuously for tight process control.

Core Capabilities

Motion-synchronised spectroscopy for inline coating-density control.

• Motion-synchronised capture — Spectra timed to the high-speed film on the production line.
• Ink-density monitoring — Tracks deposited CMYK ink density for process control.
• Production-grade throughput — Hundreds of spectra per second, continuously.
• 100s/sec — Spectra captured for process control
• CMYK — Thermal-transfer ribbon density
