What is the purpose of ink

(1) Ordinary water-based flexographic ink This series of inks is mainly used for printing paper, especially for printing block printing and field printing. Mainly used for spot color printing, the operation is relatively easy, according to the requirements of the printing pattern, the printing viscosity is generally controlled in 40 ~ 60s (4 # coated cup, 25 °C).

(2) High-precision four-color overprint water-based flexographic ink This water-based flexographic ink is mainly used for high-line fine-grained anilox roller overlay printing. The ink color standard must comply with the international Pantone color standard, and the fineness of the ink is relatively small. About 15μm. The printing viscosity is controlled at 30-45s (4# cups, 25°C).

(3) Corrugated carton water-based flexographic ink This ink is mainly used for printing corrugated cartons and is suitable for printing carton boxes and cartons on slotted printing machines. The ink requires excellent ink water resistance and rubbing resistance. According to the requirements of printing presses and printing products, the general printing viscosity is controlled at 20-25s (4# coated cups, 25°C).

(4) Water-based flexographic plastic ink This ink is mainly used for printing on the surface of non-absorbing media such as polyethylene film and polyethylene paper cups. After the ink is printed on the plastic surface, it will become a printed product. The ink film will be exposed and will not be coated with glazing oil and lamination. Therefore, the ink must have very good adhesion, good drying and resistance. Water-based properties. Before use, it is necessary to have a full understanding and understanding of the brand, structure of the ink, and the surface treatment conditions of the printed materials, and to test whether the water resistance, abrasion resistance, scratch resistance, and tape-peeling fastness of the ink meet the requirements. After passing the test, it can be used on the machine. The ink printing viscosity according to the requirements of the print product.

(5) Gold and silver paperboard water-based ink The ink is mainly used for printing on non-absorbent media such as gold and silver cardboard and aluminized paper. The ink has high requirements on the drying property, adhesion fastness and water resistance of the ink. Before the ink is used, it should be clearly understood by the ink manufacturer, and whether the ink performance is in compliance with the requirements in order to avoid loss. The printing viscosity is determined according to the requirements of the print pattern, generally 30 to 60 seconds.

(6) Food packaging water-based flexo ink This ink is mainly used for direct or indirect contact with the printing of food, medicine and other packaging materials. The requirements for this type of ink must first be non-toxic, in line with national mandatory standards, and must have the identification report of the health department. The ink has high requirements for the raw materials used in the ink, and its heavy metal content and other indicators must meet the FDA hygiene requirements. Its use is the same as ordinary water-based inks.

(7) Special water-based flexographic inks include the following. 1 Water Fund, Silver Ink This series of inks is made of copper powder, aluminum powder, and additives through special processes. The ink is different from ordinary ordinary water-based inks in use. Because the density of copper powder and aluminum powder is relatively large, precipitation is easily generated and must be thoroughly mixed before use. After several hours of continuous use, thickening phenomenon (formation of metal complexes) is liable to occur. This is mainly because the pH value of the metallic ink is lower than that of general water-based inks. Due to prolonged use, the solution in the system volatilizes, and the transfer rate is high. Unbalanced results in a change in the entire ink system. In order to avoid the occurrence of the above phenomenon, it is better to use a circulating pump closed-type squeegee in the course of use, so as to achieve less ink and increase the amount of ink, and control the temperature and viscosity of the ink at the same time. The best printing temperature of metal ink is better at 25°C±3°C. According to the requirements of the printing pattern, the viscosity of the ink in the field printing is appropriate to be slightly larger, it is 60~70s. The printing viscosity is slightly lower when the dot and level editions are stamped. For about 50s. The storage of metallic ink is shorter than that of ordinary water-based inks, usually in 3 to 6 months. Adjustment of ink viscosity requires the use of special metallic ink thinners and special water-based metallic inks to adjust the hue (limited to use and increase, it should not be stored for a long time) . 2 Fluorescent, transparent water-based flexographic ink The ink is made according to special requirements. The raw materials used are distinguished from ordinary water-based inks. For example, transparent ink uses dyes or pigments with good transparency as colorants, and fluorescent inks are used with Good fluorescent organic pigments are colorants; at the same time, in the selection of additives, the compatibility with other raw materials should also be taken into account. The usage of these inks is similar to that of common inks, and the printing manufacturers can use them according to the requirements of the printing patterns. With the order, it is not suitable for long-term storage and storage.
