The World’s First In-Line Multi-Probe Spectrometer

SpectroSave is an in-line spectrometer that integrates within the production line, providing on-site and real-time QA of colors. SpectroSave can communicate with the gravimetric or volumetric ColorSave feeder, providing real-time feedback and correction of dosing quantities for nearly 100% of machine cycles.

SpectroSave supports a wide range of high-demand and real-time QA applications including:

  • Digital setting of the pass/fail criteria,
  • In-line testing of product color,
  • Real-time analysis of masterbatch dispensing, and
  • Automatic color shade adjustment.

Multiple Modes & Probes

SpectroSave is a single system with interchangeable probes:

  • Reflected color
  • Translucent material color
  • Opacity or
  • Haze (by special demand only depending on specific application)

These high stability probes include a small form factor, and are impervious to distance, surface texture, and lateral or angular positioning, as well as resistance to vibrations, varying temperatures and suitable for typical manufacturing environments. The probes enable “plug-and-play” installation and operation, and require no special alignment procedures or complex calibration routines.

SpectroSave can also  be operated in either differential or absolute modes, enabling measurement of new-product color differences with either a reference part or coordinated L*a*b*

In-Line Quality Control

Beyond the in-line Quality Control, with SpectroSave, factories can turn their existing LIAD’s gravimetric or volumetric feeders into “Smart Feeders”, objectively setting and altering the masterbatch dosing set point by comparing and altering the ∆E of the new product in real-time.  In such a scenario, SpectroSave can even be attached to a post-production robot, enabling a fully automated solution for real-time testing and correction of additive dosing, as well as automatically discarding products that don’t meet QA requirements.

SpectroSave allows factories to speed up production, improve QA and minimize the color additive material consumption to the absolute minimum necessary; resulting in significant cost savings.
