The document discusses the data color instrument, which measures the color strength of fabrics based on light reflection properties. It outlines the methods for calculating color strength and differences, indicating that a difference value (de) below 1 is acceptable for pass criteria. It also mentions the use of spectrophotometers for shade matching and recipe adjustments to achieve the desired color results.

- 6. Data Color: Data color is an optical Instrument constructed based on the reflective property of light in order to measure color strength of a substrata specially fabric.

- 8. 1.Color strength. 2.Color difference. 3.CIA (commission of international de ecrailage) 4.Recipe prediction and recipe correction.
- 9. K/S = (1-R)*2/2R R= reflection % here K/S value is proportional to R% 1.Measurement technique of Color strength k/s value
- 10. dE=(dL^2 +dA^2 +dB^2)^0.5 dL=L1-L2 dA=A1-A2 dB=B1-B2 If dE is less than 1 then the sample becomes pass otherwise it will fail
- 11. If L*=0 then the substrate becomes 100% black or R%=0 If L*=100 then the substrate becomes 100 % white
- 12. To get the desired shade which colors are mixed together, it can be selected very easily by using spectrophotometer After dyeing one sample it can be compared with the standard one. If there is shade variation on color difference dE is considered to be greater than 1 then the recipe can be corrected for getting the desired shade%
