Textile Color Measurement
From dye to material, Konica Minolta Sensing Americas offers high performance instrument, software, and controlled lighting solutions used to formulate colors and meet color quality standards for the textiles and apparel industry. These solutions allow users to accurately evaluate, reproduce, and control the color and appearance of various samples, including dyes, fabrics, yarns, and fibers, in a more streamlined process internally and throughout the supply chain. As a result, consistency can be maintained and color quality standards can be met with less waste, time, and effort.
What is Color Measurement In Textiles?
Color measurement in textiles is the quantitative evaluation of a fabric’s color to ensure accuracy, consistency, and alignment with design or production standards. Using spectrophotometers like Konica Minolta’s CM‑26dG (high-precision hand-held instrument ) and CM‑36dG (laboratory-grade instrument), manufacturers can objectively capture both color and gloss—critical for materials whose appearance changes with texture and finish. These instruments measure reflected light across the visible spectrum and translate it into standardized color spaces (such as CIE L*a*b*) so teams can digitally communicate color globally without subjective visual variation. In textile workflows, this ensures reliable color matching between batches, suppliers, and product lines, reducing rework and improving quality and sustainability. Ultimately, color measurement enables predictable, repeatable color reproduction from initial design through final production.
How to Calibrate Textile Color Measurement Instruments?
There are two types of calibration: Daily (user) and Annually (service engineer)
Daily Calibration
Calibrating textile color measurement instruments ensures that every reading is accurate, repeatable, and aligned with global color standards. For Konica Minolta’s CM‑26dG and CM‑36dG, calibration is a quick but essential routine performed at the start of each measurement session—or whenever environmental conditions change (+/- 5 C)
How to Calibrate Textile Color Measurement Instruments (CM‑26dG & CM‑36dG):
- Warm‑Up Period: Allow the instrument to reach thermal stability (typically a few minutes) to ensure the light source and sensors stabilize.
- White Calibration: Place the supplied certified white calibration tile on the measurement port and initiate the white‑calibration routine; this sets the instrument’s baseline reflectance.
- Black Calibration: For instruments equipped with a black trap (both the CM‑26dG and CM‑36dG), perform a black calibration by measuring the light‑absorbing black cavity to establish the zero‑reflectance point.
- Gloss Calibration (for “dG” models): Because both instruments measure color + 60° gloss, use the supplied gloss‑calibration standard to ensure gloss readings remain accurate—critical for textiles with sheen, coatings, or finish variations.
- Calibration intervals: Instruments should be calibrated prior to each shift (or every 8 hours) and/or if there is a temperature shift of +/- 5 C.
When performed routinely, these calibration steps guarantee that your textile color measurements remain consistent across batches, operators, and global production locations.
Annual Calibration
Annual service calibration is a comprehensive, factory‑level recalibration performed to ensure the CM‑26dG and CM‑36dG continue to measure color and gloss with high accuracy. Over time, internal components such as light sources, sensors, illumination optics, and gloss detectors can drift due to normal aging or environmental exposure, making annual service essential for maintaining traceability to international standards. During the service, Konica Minolta technicians perform a full diagnostic check, replace or adjust internal components as needed, clean and realign the optical system, and recalibrate the instrument against certified reference standards that are far more precise than the daily user calibration tiles. The process concludes with a new calibration certificate, confirming the instrument meets factory specifications and remains compliant for quality system audits. Regular annual service calibration ensures long‑term measurement stability, minimizes color‑related production errors, and extends the operational life of the instrument.
What are the Industry Standards for Textile Color Accuracy?
Textile color standards ensure that color is measured consistently and objectively across global supply chains. The foundation of this accuracy is the CIE colorimetric system, which provides standardized color spaces, such as CIE L*a*b*, that enable precise, repeatable communication of color in textiles. In addition, ASTM E1347 offers a widely recognized method for performing tristimulus colorimetry, defining requirements for instruments, illuminants, sample preparation, and measurement geometry to ensure accurate and repeatable color evaluations across materials including textiles. Internationally, the ISO 105 series provides a comprehensive set of textile‑specific colorfastness standards, covering lightfastness, washing, perspiration, crocking, and staining evaluations used throughout dyeing and finishing operations. Complementing ISO, AATCC standards, with many application Test Methods (TM) and Evaluation Procedures (EP) form a core framework in North America for assessing color durability and performance in textiles. Together, these standards ensure that textile manufacturers, brands, and laboratories can reliably evaluate, match, and control color from raw materials to finished goods.
