FAQs About  ISO Test Charts

SCI&SCE are two method in the color measurement. SCI means Specular Component Include,SCE means Specular Component Exclude.

Under the method of SCE, only test diffuse refection and exclude specular reflection. In that way, the test result is similar to object color was observed by human eyes.

Under the method SCI, both the diffuse refection and specular reflection will be included. In that way, the value about the color is more objective. It will not effect by the environment condition.

When we choose the instrument, those elements should be taking into consideration.


Smooth and uniform surfaces with a large amount of reflected light directly result in high gloss. Some of the factors are the smoothness of the surface, the type of paint that is being used, the thickness of the coating, and curing. The lesser the surface irregularities, the greater the gloss.


Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.


Gloss paint can be identified by visual inspection and using a gloss meter. The high gloss paints are shiny and reflective like a mirror, satin or eggshell has a soft sheen, whereas the matte paint is non-reflective with very little or no reflection.

In industrial production and quality control, color consistency is one of the core elements determining product quality. Whether it is the metallic paint for automobile coating, the dyeing effect of textile fabrics, or the ink matching in packaging and printing, subtle color deviations may lead to cost waste or damage to brand image.

The LAB color space defines colors with a three-dimensional model:

  1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

  2. Hue and Saturation (a and b):

    • The a-axis represents the red-green tendency, with positive values leaning towards red and negative values leaning towards green;

    • The b-axis represents the yellow-blue tendency, with positive values leaning towards yellow and negative values leaning towards blue.

It is a globally recognized standard and supported by most modern color measurement equipment. Color is quantitatively analyzed by measuring Lab values with instruments.
