Terminology Description

Based on the test report, you can check the following dyeing quality.

A. Fastness

"Fastness" indicates resistance (durability) to various external conditions of the color.

Higher grades mean higher resistance (durability).

We generally use the following test methods for fastness:

Sunlight : KS K ISO 105 B02 2016(Xenon arc) / Washing : KS K ISO 105-C06 : 2010 A1S

Rubbing :  KS K ISO 105 X12 2016

B. Leveling

"Leveling" is the uniformity of colors in the result of dyeing (fabric).
Listing=Fabric Left and Right Deviations / Ending=Fabric First and Last Deviations

The higher the number, the lower the deviation.

C. Reproducibility

"Reproducibility" means the degree of reimplementation of the same color.
"ΔE" is a measure of how the human eye recognizes color differences, ranging from 0 to 100.

The lower the number, the less color difference.
