On-Line Systems

Respond to Product Color Changes When They Happen, As They Happen

On-line systems provide continuous, real-time measurement of your product on a process line. This allows you to respond to product color changes when they happen, as they happen. HunterLab on-line instruments make real-time color measurements of your product, without contact or intrusion, as it is being produced. From the beginning to end, production runs can be continuously monitored to identify color variation and out-of-spec product. This information helps you make permanent process improvements, while providing assurance that your product is within specification and allowing you to make shipment and allocation decisions.

Our on-line systems help you in four major ways:

  • Monitoring the finished product quality
  • Making decisions about allocating product to a customer
  • Monitoring the process variables that affect color
  • Helping you to control process variables
