Why PROFILE/Plus® Opacity Calibration Matters

Accurate opacity measurement is essential for ensuring print clarity, visual appearance, and specification compliance. Without correct calibration, even high‑precision opacity instruments can drift over time, leading to inconsistent data and increased quality risk.
Calibration of PROFILE/Plus® opacity instruments helps manufacturers:
  • Maintain repeatable, standard‑compliant opacity results
  • Ensure consistency across laboratories and production sites
  • Support customer specifications and quality audits
  • Reduce waste caused by optical variability and rework
This calibration sequence is essential for:
  • Paper and pulp mills
  • Tissue and hygiene product manufacturing
  • Paperboard and cartonboard production
  • Packaging quality‑control laboratories

Calibration Overview

  • Measured property: Paper and board opacity
  • Applicable standards: TAPPI T425, ASTM D589
