The application of colorimeter in practical color measurement

Abstract: The application information of colorimeter in actual color measurement is provided by excellent flowmeter and flowmeter manufacturers. In the industry, product color consistency is required. During the production process of different batches of products, due to the influence of raw materials or production process, there will be deviations in product color, thereby reducing the quality of products, and in serious cases, it will not be accepted and delivered. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application of colorimeter in actual color measurement. In the industry, product color consistency is required. During the production process of different batches of products, due to the influence of raw materials or production process, there will be deviations in product color, thereby reducing the quality of products, and in serious cases, it will lead to failure to accept delivery. At this time, we need to control the color difference of the product color. Control method 1: Control the quality of our products To ensure the color consistency of each batch of products, we must first formulate a product color standard as the factory standard. A certain amount of samples can be taken from different batches of the same product (hereinafter referred to as A product) for measurement. After the measurement, the products with relatively large chromatic aberration were selected from them, and the remaining products with relatively close chromatic aberrations were used as the calibration samples of the A product. Measure the color values ​​of the calibration samples in turn, and calculate the average value (the instrument can automatically calculate the average value). The average value is stored in the instrument as the color factory standard of A product. The stored sample number can be set to 001 for easy memory. If there are multiple products, the factory standard can be measured in sequence according to the above method, and stored as 002, 003, etc. In the future production process, to check whether the color of product A is qualified, you can call out the standard sample value (data 001) of product A from the storage, and then locate the standard value. Sampling and measuring from each batch of A product, the measured color difference value is the result of comparing with the factory standard. The color difference value (dE) of the product is now controlled within 1 or 1.2 by most manufacturers, that is, the color difference value (dE) is within 1 or 1.2, and there is no color difference.>1 or>1.2 is artificially chromatic aberration. If the product is compared with the standard value, the resulting color difference value (dE)<1 or<1.2, the product color is qualified, otherwise the color difference value (dE)>1 or>1.2 means that the color difference is too large and unqualified. For other products, the corresponding product factory standard is called out in this way, and the measurement and analysis are carried out after setting the standard value. Control method 2: Production according to standard samples Many companies order production according to the samples provided by the ordering company. You can measure the samples provided by the other party, store the measurement results in the instrument, and remember the stored sample number as a standard. sample. When applying, the value of this standard sample is called up and set as the measurement standard value, and then the produced products are measured in turn, according to“method one”The steps to test the color difference value of the product and evaluate whether the color of the product is qualified. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Application of Colorimeter in Practical Color Measurement'
