With the continuous development of printing technology, the accuracy and consistency of color have become an important indicator of the quality of printed matter. As an advanced color measurement instrument, the printing colorimeter plays an increasingly important role in the color measurement of the ink room. This article will introduce the principle, types and applications of printing colorimeters in ink chamber color measurement.
First, the principle of printing colorimeter.
The printing colorimeter is a high-precision color measurement instrument based on color science and optoelectronic technology. It measures the spectral reflectance of the reflected light or the spectral transmittance of the transmitted light by emitting light sources of different wavelengths, so as to obtain the color parameters of the measured object. The colorimeter uses the color space specified by the CIE (International Commission on Illumination), such as L*A*B*, L*C*H, etc., to represent the color, and calculates the difference by comparing it with the standard color sample, so as to obtain the difference.
Second, the types of printing colorimeter.
1.Portable Colorimeter: A portable colorimeter is a small, lightweight, and easy-to-carry color measurement instrument for color measurement and quality control during the printing process. It has the characteristics of easy operation, fast measurement, high precision, etc., and can quickly and accurately measure the color of printed matter.
2.Colorimeter: A colorimeter is a fixed-mounted color measuring instrument, usually installed above the printing cylinder of a printing press, to monitor the color of the printed matter in real time. The colorimeter has the characteristics of high precision, high speed and high stability, and can realize the color measurement and quality control of printed matter.
3.Reflective colorimeter: A reflective colorimeter is an instrument that measures the color of the surface of an object, usually using an integrating sphere measurement. Reflective colorimeters can measure the spectral reflectance and color values of objects, and are widely used in printing, coatings, plastics and other fields.
4.Transmission colorimeter: A transmission colorimeter is an instrument that measures the transmitted light of an object, and is usually used for color measurement of transparent materials such as paper and film. Transmission colorimeters can measure the spectral transmittance and chromaticity values of objects, and are widely used in printing, packaging, glass and other fields.
3. The application of printing colorimeter in color measurement in ink room.
1.Ink color matching: The printing colorimeter can be used to measure the color of the printing ink, calculate the difference by comparing it with the standard color sample, and adjust the ink ratio and concentration to achieve the purpose of color matching. This ensures the color accuracy and consistency of the print and improves the quality of the print.
2.Ink dryness detection: The printing colorimeter can judge the dryness and performance of the ink by measuring the color change of the ink after drying. By comparing it with a standard sample, the length of the ink drying time and the degree of dryness can be obtained, so as to optimize the printing process and improve the printing efficiency.
3.Ink stability detection: The printing colorimeter can be used to detect the stability of the ink, and judge whether the ink is oxidized, yellowed and other unstable phenomena by continuously measuring the color change of the ink for a long time. In this way, ink problems can be detected and dealt with in a timely manner, and the color quality of the printed matter can be guaranteed.
4.Ink mixing effect evaluation: The printing colorimeter can be used to evaluate the color effect of different inks after mixing, and judge the uniformity and stability of ink mixing by comparing the color difference value of the mixed ink with the standard sample. This optimizes the mixing process of the ink and improves the color effect of the printed matter.
In summary, the printing colorimeter plays an important role in the color measurement of the ink room. By using a printing colorimeter, the color parameters of the ink can be accurately measured, improving the quality and stability of the printed matter. In the future, with the continuous progress of technology and the expansion of application fields, the printing colorimeter will play a more important role in the printing industry.
