How to choose plastic gravure printing ink for the

How to choose plastic gravure printing inks by packaging and printing factories? The resistance of the ink is the resistance of the printing ink film to harsh conditions, including light resistance, heat resistance, reloading samples, grease resistance, chemical resistance, etc. If it is necessary to boil the printing ink and pigment blank of sterilization packaging, it needs to have boiling resistance

in the printing production, the economic packaging printing factory pursues low investment and high return, that is, according to the principle of appropriate packaging, on the premise of meeting the above conditions, choose the ink with low overall cost (purchase cost plus use cost, etc.). Although the packaging and printing factory chose the appropriate ink, there were many problems caused by the ink itself in the process of using the ink. So, what are the higher requirements of packaging and printing plants for ink

requirements of packaging and printing plants for inks in order to optimize their operating costs, improve the stability of production, and meet the requirements of customers, packaging and printing plants, while producing high-quality products, improve production efficiency, improve the production environment, and meet the environmental requirements of customers for products are the basic requirements of packaging and printing plants for inks. Reducing use costs, reducing costs and maximizing profits are the premise for the survival and development of enterprises, and packaging and printing plants are no exception. Although ink only accounts for 15% of the printing cost (paper accounts for 45%), according to our understanding, the printing factory has never given up its efforts to reduce the ink cost. The packaging printing factory hopes that the ink supplier will provide ink products that meet the requirements with the best cost performance. In order to reduce the printing cost, printing factories hope that printing ink manufacturers can improve the coloring of printing ink and print more moving parts with quantitative ink or use the least amount of ink for quantitative moving parts. However, the amount of ink is closely related to the colorability of ink

in the case of a certain amount of ink, the higher the colorability of the ink, the more live parts printed, and the greater the profit. Reduce the use of additives or use supporting additives. On the one hand, printing plants hope that the ink used can be used directly during printing, without adding or adding little to help the domestic plastic gravure ink market. At present, in the domestic plastic flexible packaging industry, large-scale enterprises account for only about 10%, while small and medium-sized enterprises account for more than 90%

large plastic packaging enterprises have advanced printing machines and fast printing speed (high-speed printing machines); The product is of high grade, large batch, specific variety, high quality and large amount of ink. Generally, the ink produced by two to three ink manufacturers is used at most. However, the printing machines of many small and medium-sized plastic packaging enterprises have been updated in recent years; However, medium and low-speed printing presses still account for the majority. Its equipment and conditions are poor, and it produces many varieties, small batches and small quantities. Therefore, the ink used is miscellaneous, and there is no fixed ink. The ink manufacturer has no spots, rust and other phenomena. Generally, the low-cost ink is the first choice

ink varieties in plastic rubber static stiffness electronic universal testing machine functions: in soft packaging, food packaging, salt packaging, cosmetics and daily necessities packaging, pharmaceutical packaging, paper products packaging, clothing packaging: food packaging is based on composite printing ink, and some candy paper uses surface printing ink; Cooking packaging uses high-temperature cooking ink, while general vacuum packaging uses polyester ink; Dairy products should be packaged with water-resistant, acid resistant and temperature resistant inks. Polyester ink is mainly used in drug packaging and cosmetics packaging

some manufacturers of salt packaging use surface printing ink, some manufacturers use composite inner printing ink, but more manufacturers use polyester ink. Many surface printing inks are used in daily necessities packaging, paper products packaging and clothing packaging, but the surface printing white ink should be special, smooth, scratch resistant and anti adhesion ink. With the improvement of the packaging market, more and more composite printing inks are used

price of plastic gravure printing ink at present, the price of plastic ink is divided into three levels: high, medium and low. The ink market prices of Shanghai DLC ink company, Jiangmen Toyo ink company, Shenzhen shenri ink company, etc. are higher. The ink prices of Shanxi Xiongying ink company and Zhejiang New Oriental ink company are in the middle. The ink price of Zhejiang yongzai chemical company is low, but there are too many small ink manufacturers producing low-priced ink in China

market price of general plastic gravure printing ink: how to use alcohol soluble gravure printing ink in cooking? Alcohol soluble gravure printing ink is a colloidal liquid with good fluidity after fully grinding and dispersing alcohol soluble synthetic resin, solvent and organic pigment. It is a volatile dry ink with good printability, fast drying, bright luster, bright colors, etc. It is suitable for printing and packaging cellophane and candy wrapping paper for food. The printing speed is m/mm. However, for developers in most cities across the country, the use method of alcohol soluble gravure printing ink: it should be stored at a lower temperature, and the ink should be fully stirred before use to make it have good flow performance. Alcohol soluble inks should meet the requirements of computer application in terms of viscosity, thinness and dryness. If the ink is too thick, it can be diluted with ethanol (which can speed up drying) or butanol (which can slow down drying), or diluted with diluent. If the printing machine dries slowly due to its high speed or winter climate, a quick drying agent can be added to accelerate its dryness. Japanese inks can be mixed with each other to adjust various colors. However, it should not be mixed with other types of inks to avoid resin precipitation and other unusable phenomena
