SpectroEdge
Inline Spectrophotometer for Digital Press Manufacturers
SpectroEdge has been designed for inclusion inside a wide variety of digital print engines. It is a compact and highly accurate scanning spectrophotometer that can measure 3,000 samples per-second which allow it to measure at full production press speeds. Inclusion of SpectroEdge inside a digital press allows for linearization, calibration, ICC profiling, and color quality measurements to occur in real-time and without operator intervention for increased color accuracy, increased color consistency, and a more seamless user experience.
Benefits of Inline Color Measurement
Automation for Increased Color
Accuracy & Consistency
- Integration inside the press allows for automated spectral color measurements
- Allows for closed-loop color control without user intervention
- Automate the linearization, calibration, and ICC profiling process
- Increases color accuracy and color consistency of the press
- Measurement process is 100% automated & relieves burden from the operator
The Heart of In-Press Color Control
Solution Components
- ES7500 scanning spectrophotometer
- Optional traverse arm for movement across material width
- Software Developer Kit (SDK) to control: ES7500, traverse arm, and receive measurement data
SpectroEdge
KEY FEATURES:
