How many factors do you know about the factors that affect the color measurement of colorimeter? The color difference meter is a simple color deviation test instrument, that is, to make a filter that simulates the spectral characteristics of the color sensitivity of the human eye, and use it to measure the light of the sample, the key is to design the spectral sensitivity characteristics of this photoreceptor.
, and can be measured and displayed by computer software under a certain light source
.

And what we want to know below are the factors that affect the color measurement of the colorimeter.
Let's understand together
.

1.
Color Spaces: As far as color is concerned, many measurement systems exist
.

There are currently five complete color spaces available: CIE XYZ; CIE Yxy; CIE L*a*b*; CIE L*C*h; and Hunter Lab
.

Each of these scales consists of three numbers
.

Therefore, it is important to use the appropriate color space for your samples and use the same color space every time in order to create a uniform standard between samples
.

2.
CIE light source: The color measured by the colorimeter is also affected by what type of light is used
.

Colorimeters can work with many light sources, including A (tungsten), F02 (cool white fluorescent), C (average daylight), and D65 (noon daylight)
.

While there are good reasons to use any of these light sources, use the same type of light source when determining color consistency or variation across samples
.

3.
CIE standard observer angle: There are two types of standard observers: 2 degrees in 1931 and 10 degrees in 1964
.

Although there are significant similarities between them, there are also differences that may affect the color data
.

Therefore, it is important to use the same standard observer for each sample
.

　　4.
Instrument lighting method: The colorimeter lighting method you choose will have a major impact on how color data is captured
.

The current common colorimeter illumination methods are 45°/0° or 0°/45° instruments and diffuse/8° spherical instruments
.

Which one to choose will largely depend on the type of sample you are working with; in some cases, it will also depend on whether you want to measure appearance or color separately
.

　　5.
Sample Preparation: Proper sample preparation is an important part of obtaining accurate color data
.

This is also an important aspect that human factors may cause measurement inconsistency
.

Therefore, standardized sample preparation procedures were developed
.

　　6.
Sample measurement: The sample measurement consists of many factors, including the way the sample is positioned, the sample view area, the measurement mode, and the number of average sample readings
.

As with sample preparation, take steps to minimize sample variability, including the use of standardized procedures or instrumentation, to minimize the chance of or sample variability
.

　　Consistency of measurement parameters will optimize your ability to compare samples at any stage of your product development or manufacturing process, giving you the data you need
.

　　Measuring color is affected by six factors, each of which plays a vital role in the way a colorimeter captures color information
.

Changes in any of these factors can alter the color data, creating differences between the numbers obtained by two identical samples or two different colorimeters
.

 The above is an introduction to the factors that affect the color measurement of the colorimeter.
I believe that everyone has a corresponding understanding of this after reading, and I hope it will be helpful to everyone.
