FAQ – How Do I Integrate SpectraTrend HT into My Existing Laboratory Color Quality Program?


Answer

SpectraTrend® HT is designed to complement and enhance laboratory color quality programs by providing continuous, real-time process monitoring. Rather than replacing laboratory measurements, STHT helps identify color shifts as they occur so corrective action can be taken before significant quantities of off-spec material are produced.

Why Do STHT and Laboratory Instruments Measure Differently?

STHT uses a specialized inline geometry optimized for process monitoring under actual manufacturing conditions. Laboratory instruments use standardized geometries designed for quality control, specification compliance, and product acceptance. Differences can result from:

  • Geometry.
  • Illumination.
  • Product temperature.
  • Surface conditions.
  • Process environment.
  • Measurement location.

What Is the Best Solution?

The most effective color quality programs utilize:

  • Laboratory instruments for quality control.
  • STHT for process control.

Together, the systems provide both standardized product measurements and real-time process visibility.

Best Practices

  • Establish laboratory standards first.
  • Implement STHT as a process-monitoring tool.
  • Perform a correlation study during startup.
  • Develop STHT action limits based on actual production data.
  • Verify significant process shifts using laboratory measurements.
  • Periodically review correlations and operating limits.

Practical Guidance

A typical implementation workflow is:

  • Establish laboratory standards and tolerances.
  • Install STHT on the production line.
  • Perform a correlation study.
  • Establish STHT operating limits.
  • Use STHT to monitor process stability.
  • Use laboratory measurements to verify product quality.

This approach maximizes both process control and quality assurance.

Key Takeaway

STHT should be viewed as an extension of the laboratory rather than a replacement for it. The greatest value is achieved when real-time inline monitoring and standardized laboratory measurements work together as part of a comprehensive color quality control strategy.
