The main purpose of color matching of colorimeter

The colorimeter, together with the computer color management software, realizes the modern industrial digital color matching function, mainly to complete the color matching work perfectly, and reduce the workload of color management personnel to achieve human liberation. Color matching of colorimeter mainly includes five aspects of color management, including formula modulation, formula correction, color measurement, color difference control and daily color management, each of which is very important.

Recipe preparation
First of all, we need to establish a color database dedicated to color matching, and input the commonly used pigment data into the database. After that, when the color needs to be prepared, you can directly input the color plate of the incoming material into the computer, click several candidate pigments in the keyboard, calculate and finally determine the formula of dyeing and coloring pigments in the computer software according to the sample information measured by the colorimeter. Then set the tolerance range as required to realize online color monitoring of the colorimeter

Formula correction
When a color formula is determined, color changes are found in the production process. This is based on the color data measured by the colorimeter and the formula calculation method in the computer software to adjust the formula, and correct the formula to be identical with the customer’s sample information or within the tolerance range required by the customer.

Color measurement
The biggest function of the colorimeter is color detection, but it is not enough to only detect the color information of products in the requirements of modern industrial coloring. The function of the colorimeter is also improving with the requirements of manufacturers and customers. Now the colorimeter can measure the tinting intensity of the colorant, the whiteness of the product, the color fastness of the product, the color difference, etc. It can be said that the functions are very comprehensive.

Color difference control
Color difference is a major killer of color products. Once a customer is dissatisfied with the color difference of the product, this batch of products will be scrapped, which is a great loss to the manufacturer and has an impact on its reputation. At present, the industrial color difference instrument strictly controls the color difference problem and quantitatively expresses the performance index of color, which is conducive to the treatment and control of color difference problem

Daily color management
Daily color monitoring data recording is very important. These data should be completely stored in the computer color database according to the production date, formula, color sample, industrial conditions and customer information to facilitate future color detection.

To do a good job in color management of color matching is the most important work of each color manager and also an important issue that manufacturers and customers are concerned about.

Application of colorimeter:
The colorimeter is often used in industrial production. Its main function is to compare the color difference between the sample plate and the tested object, output three groups of data (L, a, b) and four groups of color difference data (△ E, △ L, △ a, △ b) after color comparison. In addition, the powerful colorimeter can also be used to measure the reflection chromaticity of the sample, as well as the absorbance, brightness, various color values, K/S values, chromatic conductivity, coverage, whiteness, yellowness, etc.
First of all, we need to know the meaning of the data represented by the colorimeter, and then we can apply it to various industrial production. The size of the total color difference of E, large L means partial white, small △ L means partial black, large a means partial red, small △ a means partial green, large b means partial yellow, and small △ b means partial blue. In the field of color management, the color difference meter is widely used. The color detection of products in industries such as plastics, coatings, textiles, medicine and food is fast and convenient, and the data is accurate, which greatly improves the product qualification rate. In some color matching industries, such as paint, printing, etc., it will also be used to assist color matching. It can be adjusted carefully according to the data, and the ideal color formula can be obtained only a few times.

In view of the performance of the colorimeter, it is widely used to analyze and control the quality of various production processes, that is, color monitoring, including the quality assurance of incoming materials and finished products.

 Factors of Necessity of Using colorimeter
1. Digitization
The arrival of information digitalization is full of digitalization in both life and production. Digitalization brings us a lot of convenience, such as computers, mobile phones and various communication devices. Similarly, in industrial production, the digitalization also brings a lot of convenience to production. The digitalization of color information makes the color difference analysis clear, fast and with small error. Color difference instrument is an instrument to convert color into data abstractly. The current colorimeters are all foolproof and basically realize one click measurement, which can quickly, accurately and clearly display color data information.

2. Intelligence
Color difference meter can store and transfer abstract color information into digital form, which provides a basis for intelligent color reproduction. The color difference meter measurement results can be permanently retained by using the quality management software and color matching software to process, analyze and establish a database, which provides a strong backing for the later color replication. The traditional color analysis uses color swatches and color swatches, but we know that the color swatches and color swatches will change over time, and the products made with the original color swatches or color swatches cannot be exactly the same after a period of time. This is the color database established by the colorimeter to fill this gap. It will not change unless the data is destroyed artificially. At the same time, the digital sample information transmission is also convenient and fast, saving the time and cost of postal delivery.

3. Accuracy
Color quality control also involves a more important detail, that is, accuracy. Only accurate measurement and analysis of color difference information can better complete the production task. At the same time, it can reduce the loss caused by defective products. The current color difference meters in the market have different fields and products with different precision. It is OK to choose products with appropriate credit price ratio according to your own product situation.

4. Universal
Although not all models and brands of colorimeter data can be universal, if manufacturers and suppliers use the same brand and model of colorimeter, the measurement data is completely consistent. We know that the color difference meter is calculated by using the chromaticity space and color difference formula, which has no requirements for external environment and personnel. As long as the same colorimeter is used, there will be no difference in the audit results due to different personnel.

5. No external interference
The colorimeter is a standard detection environment that has been set with components inside the electronic instrument, so that the color master will not pay attention to the surrounding environment, analysis time and personal emotions when testing. Being free from the interference of these external factors can greatly improve the measurement efficiency, and then improve the production efficiency.
