How to measure the color of fabric with spectrophotometer CS-820?

Test Condition

  • 1. Mode: Reflectance
  • 2. Light Source and Angle: D65/10 degree
  • 3. Parameters need to Measure: color value L*a*b and ΔE*ab.
  • 4. Because the fabric is translucent, we will use one A4 paper to make sure no light will enter into instrument to affect test result.
  • 5. Make sure the test direction is same when measuring target and fabric because fabric is woven.

Test Method

1. Measure the color of the target fabric firstly. Then get its L*a*b, then measure the sample fabric to get the color differenceΔE*ab.

The following are the test result:

Company with the target, sample contains too much white and total color difference is Delta E*ab 1.43. These two colors are difference from each other.20180926165351 99127 - How to measure the color of fabric with spectrophotometer CS-820
