How to Visually Evaluate Textiles

Evaluating textile color palettes, fabric rolls, multiple garments side-by-side, and cut-and-sew pieces under controlled lighting can ensure color integrity and harmony before garment assembly and shipment. X-Rite SpectraLight QC Luminaires can be hung in custom configurations over a viewing table to achieve the desired light level and area of view.

Challenge

Solution

SpectraLight QC Luminaries can be hung on chains over a viewing table to evaluate color under 7 light sources, including best-in-class dimmable filtered-tungsten halogen daylight and optional LED. The luminaires can be arranged in custom daisy-chain configurations in banks as small as 1x2 and as long and wide as needed to achieve the desired light level and area of view.

During design, R&D and final QC, evaluators can walk around the textile products to evaluate color from every angle and ensure color integrity and harmony under multiple lighting conditions, including optical brighteners under UV. SpectraLight QC is the gold standard for controlled lighting, complying with ISO: 3664, 3668, 13076, 23603, AATCC: EP9, ASTM: D1729, SAE: J361, DIN: 6173, CIE: S012/E, 51.2, and BSI: BS 950 Pt.2, for a solid quality control program.

Results

How It Works

  1. Work with an X-Rite color scientist to determine the ideal size, shape, and bulb configuration. SpectraLight QC Luminaires can be hung in banks as small as 1x2 and as large as your items require.
  2. Create standard operating procedures to document settings for every program and create custom profiles based on requirements for light source, illumination, and other parameters to ensure consistency between evaluators.
  3. If desired, require part suppliers to use SpectraLight QC Light Booths to confirm dyed fabrics and components are visually acceptable based on standard operating procedures before they are shipped for assembly.
  4. Everyone perceives color differently, so it is important to test the vision acuity of quality controllers and approvers to understand how they perceive color. The Farnsworth-Munsell Hue Test can be used to fully analyze color vision for in-house and field staff involved with color-critical operations.
