What is the HunterLab SpectraTrend HT, and how does it improve real-time color monitoring in production?

SpectraTrentHT

The HunterLab SpectraTrend HT is a non-contact; inline spectrophotometer designed for continuous color measurement directly on the production line. It enables real-time monitoring and control of color for a wide range of flat, smooth, or textured products—without interrupting the process. With its 45°/0° optical geometry and advanced software integration, SpectraTrend HT provides immediate feedback for closed-loop color control in high-speed manufacturing environments.

Key Features

  • Continuous, non-contact color measurement at high line speeds
  • 45°/0° geometry mimics human visual perception
  • Embedded industrial-grade touchscreen for standalone operation
  • Ethernet and PLC connectivity for easy integration into existing systems
  • Optional height adjustment and air purge system for dusty environments

Benefits for Customers

  • Enables real-time quality control, reducing waste and rework
  • Improves consistency across batches and shifts by catching color drift early
  • Minimizes downtime by detecting problems before full production runs are affected
  • Enhances compliance with color specifications through automated monitoring
  • Supports data logging and trend analysis for continuous improvement

Industries That Benefit
SpectraTrend HT is ideal for fast-paced production lines in industries such as:

  • Food (e.g., snacks, bakery, cereals)
  • Plastics and films
  • Building materials (e.g., flooring, siding)
  • Paper and pulp
  • Textiles and non-wovens

How It Helps
The SpectraTrend HT helps manufacturers maintain tight color tolerances in real time without relying on manual sampling. By automating color checks, it reduces human error, speeds up correction response time, and increases overall yield and product quality. This leads to lower production costs and higher customer satisfaction—especially in industries where visual uniformity is critical.
