Empirical color matching method
The empirical color matching method refers to the color matching based on the experience and feeling of the color matcher without a color measuring instrument. The early stage is based on the experience accumulated by the color matcher from practice, and the color matching in the middle and late stages is based on 10 basic color maps. or printing.
The color spectrum serves as a reference standard for visual color measurement. The empirical color matching method is often affected by the physiological and psychological factors of the color matcher and other objective conditions, and the product quality is difficult to maintain stability. In addition, relying on experience and feeling color matching can only be qualitative, not quantitative, and it is difficult to disseminate and communicate technology.
mechanical color matching
The mechanical color matching method is a more professional color matching method that has gradually become popular in modern times. In each link of color matching, certain machinery and instruments are used as configuration and measurement tools. By drawing curves and charts as a reference for color matching, the color matching work is relatively accurate. carried out within the range. This method changes some of the blindness of color matching in the past experience, and improves the speed and quality of color matching, but the accuracy of color matching is low and the error is large.
computer color matching
Computer color matching has a history of about 30 years abroad, and it has been applied in many color-using departments at home and abroad. People use the connection between the color database stored in the computer and the relevant color matching software to analyze and process the color data on the sample, and through calculation, correction, and color adjustment, select the color formula that suits the requirements of the sample, and then complete the automatic printing of ink. color matching. Computer color matching requires standard color samples and the color of the prepared ink samples to be expressed in numbers, which ensures the accuracy and uniformity of each color matching, and greatly saves the color matching time. Convenience, speed, speed and accuracy are the advantages of computer color matching . However, the color matching software developed by different enterprises and companies are all developed on the basis of considering their actual production and application conditions, and there is no unified standard, which is one of the reasons why computer color matching cannot be popularized.
