Advanced UV Calibration Training Announced by AATCC

AATCC is hosting a live digital training session on UV calibration for textile professionals on July 29-30, 2026. The course, led by AATCC Technical Associate Carrie Gray, will focus on best practices for using the AATCC UV Calibration Reference Fabric and the AATCC Evaluation Procedure 11 (EP11).

The training is designed for those involved in fabric evaluation, color data management, or spectrophotometer use. It will cover why UV calibration is critical when measuring whiteness and fluorescent standards, and how comparing measurements with UV included versus UV excluded can reveal underlying issues in base fabrics, dyes, and optical brighteners.

Participants will also explore the impact of laundering on color consistency, improve troubleshooting of color problems linked to fluorescent or non-traditional dyes, and understand how to make more defensible color decisions. Each live session concludes with a Q&A segment.

What Textile QA Professionals Will Gain from the UV Calibration Course

Why UV Calibration Matters for Color Consistency

In textile manufacturing, accurate color measurement is essential for brand identity and product quality. When fabrics contain optical brighteners or fluorescent dyes—common in athletic wear, uniforms, and high-visibility textiles—standard spectrophotometer readings can be distorted without proper UV calibration. The AATCC UV Calibration Reference Fabric provides a controlled way to verify instrument performance, and EP11 outlines the standardized procedure. This training helps color specialists understand how to apply the standard correctly, reducing measurement variability across different labs and ensuring that final products match design specifications.

For quality assurance teams, the ability to distinguish between issues caused by base fabric chemistry, dye migration, or laundry effects can significantly cut reject rates and rework costs. By learning to toggle UV-included and UV-excluded measurements, professionals gain a diagnostic tool that goes beyond simple pass/fail checks. The session’s emphasis on live Q&A also gives attendees a direct line to an expert who manages AATCC’s Proficiency Testing Programs in color evaluation and colorfastness.
