The main purpose of color matching for colorimeter

The Colorimeter works together with computer color management software to achieve modern industrial digital color matching functions, mainly for the perfect completion of color matching work, while reducing the workload of color management personnel to achieve human liberation. The Colorimeter mainly manages colors in five aspects: recipe modulation, recipe correction, color measurement, color difference control, and daily color management, each of which is very important.

Introduction to color matching with Colorimeter:

Recipe modulation

Firstly, it is necessary to establish a dedicated color database for color mixing and matching, and input commonly used pigment data into the database. After that, if the color needs to be prepared, you can directly input the incoming color board into the computer, point out several candidate pigments on the keyboard, and calculate the final color formula in computer software based on the sample information measured by the Colorimeter. Then set the tolerance range as required to achieve online color monitoring by the Colorimeter.

Formula correction

After determining a color formula, the production process discovers color changes. This is to adjust the formula based on the color data measured by the Colorimeter and the formula calculation method in the computer software, and correct the formula to be exactly the same as the customer’s sample information or within the tolerance range required by the customer.

Color measurement

The biggest function of Colorimeter is color detection. However, in modern industrial coloring requirements, it is not enough to only detect the color information of products. The functions of Colorimeter are also continuously improved according to the requirements of manufacturers and customers. Currently, colorimeter can measure and measure the coloring strength of colorants, whiteness of products, color fastness of products, color difference, and so on. It can be said that the functions are very comprehensive.

Color difference control

One of the major killers of color products that can have color differences is that once a product has color differences that customers are not satisfied with, this batch of products will be scrapped, which is a significant loss for manufacturers and has an impact on their reputation. Currently, industrial colorimeters strictly control color difference issues, and quantitatively express color performance indicators, which is conducive to handling and controlling color difference issues

Daily color management

Daily color monitoring data recording is very important. These data must be stored completely in the computer’s color database according to production dates, recipes, color samples, industrial conditions, and customer information to facilitate future color testing.

Doing a good job in color management of coloring and color matching is the most important work of every color manager and an important issue that manufacturers and customers are concerned about.

There are six factors that affect the color measured by a colorimeter:

1. Color Space: In terms of color, there are many measurement systems. Currently, there are five complete color spaces available: CIE X Y Z; CIE Yxy； CIE L * a * b *； CIE L * C * h； And Hunter L a b. Each of these scales consists of three numbers, but each number is determined in a unique way. Therefore, it is crucial to use the appropriate color space for your samples and use the same color space each time in order to create a uniform standard between samples.

2. CIE light source: The measurement of color by a colorimeter is also influenced by the type of light used. Colorimeters can use many light sources, including A (tungsten), F02 (cold white fluorescent lamp), C (average daylight), and D65 (midday daylight). Although there are sufficient reasons to use any of these light sources, you must use the same type of light source when determining color consistency or changes in different samples.

3. CIE Standard Observer Angle: There are two types of standard observers: 2 degrees in 1931 and 10 degrees in 1964. Although there is significant similarity between them, it may also affect differences in color data. Therefore, it is important to use the same standard observer for each sample.

4. Instrument Lighting Method: The lighting method you choose for the color difference instrument will have a significant impact on the way color data is captured. Currently, the commonly used illumination methods for color difference meters 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 using; In some cases, it also depends on whether you want to measure the appearance or color separately.

5. Sample Preparation: Proper sample preparation is an important component of obtaining accurate color data. This is also an important aspect of human factors that may cause measurement inconsistencies. Therefore, standardized sample preparation procedures must be developed.

6. Sample measurement: Sample measurement includes many factors, including sample positioning method, sample view area, measurement mode, and average sample reading number. As with sample preparation, measures must be taken to minimize sample changes, including the use of standardized procedures or instruments, to minimize or eliminate opportunities for sample changes.

What are the six advantages of a colorimeter:

1. Multi color space color value display
The colorimeter has a built-in program for converting various color display indicators, eliminating the need for color measurement personnel to manually convert measurement data, greatly improving work efficiency.2. Simple and easy to use three steps to measure color difference

3. PC terminal management system
After customers purchase, we will provide color management software for free, connect the device to a computer, real-time display qualified or unqualified judgment, print test reports, and save color data for each batch. Color Spectrum Technology has a mature PC terminal management system that connects a colorimeter to a computer. It can manage test data in the upper computer software, quickly export instrument data, and print test reports, facilitating color measurement personnel to conduct more complex analysis work.

4. Stable measurement performance
standard deviation Δ E * ab 0.08 (after correction, measure the standard deviation of the whiteboard 30 times at an interval of 10s)
5. Large capacity data storage

The precision colorimeter can store 100 sets of standard sample data, and can store 100 sets of samples under each standard sample.

Portable Colorimeter/Chroma Meter is an innovation color measuring tool with powerful configuration to make color measurement easier and more professional; It support Bluetooth to connect with Android and ISO devices, Portable Colorimeter/Chroma Meter will take you into a new world of color management; It can be widely used to measure color value, color difference value and find similar color from color cards for printing industry, paint industry, textile industry, etc.
