China produced ink very early. The predecessor of ink is loose ink. In China, black ink is made from pine smoke, gum (mainly cow skin glue, which acts as a bond for soot) and water. It was first used for writing and later for block printing. Ink in China's early development of rapid, after the Middle Ages, has been complacent, meet the traditional secret recipe, not very creative. At that time, European wood printing was also based on water, but the application was poor, so it was changed to oil. Later evolved into modern printing ink. The development of printing technology stimulates the development of the ink industry, and there are inks that adapt to various printing requirements, with many functions and high quality.
Internationally recognized as the first country to use ink in ancient civilization, China began to use ink as early as the Western Han Dynasty (200 BC), this ink can write on bamboo and silk to convey information, some of its functions can be compared with contemporary ink.
The development of ink is accompanied by the development of printing plates, because the two do not match, the imprint is not clear, the ink film will fall off, affecting the printing quality. For example, the printing plate is in the engraving block period, and the ink is made of the carbon and gum evenly mixed and dried after burning the wood, which is water-soluble. When printing, the ink is applied to the plate, and then the paper is placed on it, and then the cloth or brush is gently wiped, and the text and text on the block can be transferred to the paper through the ink. The development of the metal plate period, because the water-based ink can not be evenly coated on the plate, so the invention of oil-based ink, which is the pigment evenly dispersed in the oil and made of. The original ink pigments were natural inorganic minerals, and the binding materials were plant or animal fats. This kind of ink, slow drying speed, poor gloss of the printing product, poor adhesion to the substrate. With the development of the chemical industry, it has brought vitality to the ink industry, and new synthetic resins and advanced organic pigments have been widely used in ink manufacturing, so that the varieties of ink are richer and the performance is better. The development of ink has entered a new stage, and finally the traditional lithography, relief, gravure, screen printing have a perfect and mature ink system.
With the advancement of human civilization and the development of printing industry, substrate materials are constantly developed and expanded, and printing methods are constantly introduced. The production process of ink is more sophisticated, and the types and colors of ink products are increasing. If the promotion of waterless offset printing process increases the demand for waterless offset printing ink, the rise of flexible digital printing has also made digital printing ink stand on the stage of history. As well as the strong voice of green environmental protection has set off the re-selection of ink raw materials and the reform of manufacturing process, such as water-based ink, soybean offset ink, UV ink, FB ink and so on. Ink, the largest source of pollution in the printing industry, is working hard to reduce its volatilization of organic matter and the application of harmful metals. We have reason to believe that the future development of the ink industry will move towards the general direction of caring for life, embracing nature and harmonious society. Ink manufacturer
