In recent years, people's requirements for a variety of media, such as glass and printing ink, have been gradually improved. Relief printing and gravure printing are mainly used, and their application ranges are also different.

In the ink printing process, the color problem is one of the major problems, and the color difference seriously affects the quality of products. The main causes of color difference are pressure, ink roller, ink feeding device, fountain, ink and other factors. The color difference meter is particularly important for the color difference test of ink printing industry. It is an indispensable tool for quantifying color phenomena, establishing color standards, improving product appearance, color quality control and computer color matching.

Hangzhou CHNSpec Technology Co., Ltd. has been deeply engaged in the field of ink printing for many years. In view of the color difference caused by ink printing, it has a variety of products and solutions.

1、 Decorative paper is usually printed by letterpress. It is a kind of paper that is printed with wood grain, stone grain, bamboo grain and other patterns on the decorative base paper, then impregnated with melamine and hot pressed on high and medium density MDF together with wear-resistant paper to make floors, furniture and so on for decoration and protection. The color difference of decorative paper is mainly in the printing process. Due to the influence of many factors such as large number of colors (generally 3-4 color overprint), different colors and patterns, and human, machine, material, method, ring and measurement in the production process, the color difference control is difficult and there are many customer complaints. Therefore, color difference control is a topic that many decorative paper printing enterprises are eager to discuss. CS-828 of CHNSpec technology technology is a professional image spectrophotometer, which can well meet its color detection needs.

2、 At present, the demand for cigarettes in society will continue to grow steadily, but with the improvement of consumption level and cigarette consumption grade, the proportion of high-grade cigarettes will increase year by year, the proportion of cigarette labels will increase year by year, and the demand growth of high-grade cigarette labels will be much higher than the average growth of the industry. This requires that in the production process of cigarette label, high-precision instruments are needed to monitor the color quality of cigarette label. The desktop spectrophotometer CS-820n of Hangzhou CHNSpec technology technology has been applied in the color detection of cigarette labels.

3、 Glass is an article that we often contact and use in our daily life. From daily necessities such as glass cups to building decoration materials such as glass curtain walls, glass has made a great contribution to the development of world civilization. Printing exquisite patterns on glass products is a scheme to improve quality, while controlling the color difference of glass products is a big problem. The high-precision desktop spectrophotometer CS-826 of CHNSpec technology technology can provide good help.

4、 Plastic film is a common packaging method at present. It has many uses, such as protecting goods, beautifying goods and so on. In life, we often see plastic film packaging with gorgeous colors and novel patterns. How to ensure the uniform color of plastic film packaging of each batch of products is very important. The high stability desktop spectroscopic CS-821n of CHNSpec technology technology has a good effect in detecting the color difference of plastic film.

In the actual production and use of ink printing industry, a good color difference instrument can save production cost and improve work efficiency. CHNSpec technology technology has rich experience in color detection in ink printing industry. CHNSpec technology technology connects colors with numbers.
