Three methods commonly used in printing ink color matching

The empirical color matching method is based on the experience and sensation of a colorist only in the absence of a colorimetric instrument, and is based on the experience accumulated by a colorist in practice. The color matching in the middle and later stages is based on 10 basic color patterns. Or print chromatography as a reference for visual color measurement. The empirical color matching method is often affected by the physiological, psychological and other objective conditions of the color matcher, and the quality of the product is difficult to maintain stable. In addition, relying on experience and feelings of color, can only be qualitative, can not be quantitative, technology communication and exchange more difficult.

2. Mechanical color matching

The mechanical color matching method is a more advanced color matching method that has gradually become popular in modern times. In the various aspects of color matching, certain mechanical and instrumental instruments are used as configuration and measurement tools. By drawing a curve chart as a reference for color matching, the color matching work is relatively accurate. In the range. This method has changed some of the blindness of past experience color matching, so that the color matching speed and quality have improved, but the color matching accuracy is low and the error is large.

3. Computer color matching

Computer color matching has been in foreign countries for about 30 years, and it has been applied in many color applications at home and abroad. People use the connection between the color database stored in the computer and the related color matching software to analyze and process the color data on the sample draft. Through calculation, correction, and color correction, the color formula suitable for the sample draft requirements is selected and the ink is automatically completed. Color matching. Computer color matching requirements The standard color samples and the color of the dispensed ink samples are all represented by numbers, which ensures the accuracy and uniformity of each color matching, and greatly saves the color matching time. Convenient, fast, rapid and accurate are the advantages of computer color matching. . However, the color matching software developed by different companies and companies is based on actual production and application conditions. There is no uniform standard. This is one of the reasons why computer color matching cannot be popularized.
