How to correctly select ink

when the thickness of metal pigments such as copper and zinc reaches microns, its coverage is better

plastic, paper and metal inks

plastic, paper and metal inks can be used in advertising and industrial printing. The monomer polymer is similar to the function of solvent, which plays the role of transmission and provides the necessary viscosity for printing. One component ink is composed of thermosetting resin. The ink needs to be baked and cannot be naturally dried

nitrated varnish, ceramics, plexiglass, epoxy and UV ink can be used on metal, but the ink should be selected according to the external weather resistance, chemical resistance, wear resistance and molding requirements. The ink is printed after adding diluent or slow drying agent, and the leveling property is good. When the color will fade when exposed to UV light, the surface can be protected by adding varnish

solvent based, water-based and UV inks all have metal inks. The metal effect has a good brightness on glass and vinyl substrates, but it is prone to oxidation after exposure to moisture in the air. The UV energy required for water-based reduction UV ink is lower than that of traditional UV ink with high solid content. It can withstand stamping and molding

golden metallic color is not recommended for outdoor exposure, because it will reduce the metal surface effect

in order to help choose the correct printing ink for different substrates, the characteristics of the following commonly used inks are introduced as follows:

UV ink

in recent 10 years, UV compounds have had a huge impact on the visual media market. Volatile inks can be used for printing materials such as plexiglass, acetate fiber, butyrate, digested cotton and PVC. If the factory does not have 60 feet of gas drying equipment, it can be replaced by 60 feet of gas drying equipment, which is more economical to produce. However, it should be noted that epoxy solvent will not affect the storage period

thermosetting ink is completed by entering the substrate through heat, usually 180 ° f for 30 minutes

an epoxy ink can provide a variety of catalysts to increase the adhesion to the substrate. The advantages of this kind of ink are: the ink will not dry on the printing, the ink can be diluted with water, washed with water, and the printing pattern is not easy to fade. Solvent based inks consist of resins. UV inks contain oligomers, which are different from solvent based inks. UV ink printing problems less, UV viscosity will not change, ink does not evaporate, four-color printing is easier

low function and high content of ethylene, polyolefin, light weight paper, long outdoor weather resistance, substrates requiring strong chemical resistance and strong water resistance, generally do not use water-based ink

plastic ink

the drying method of plastic ink is evaporation, oxidation or polymerization reaction type. Good covering power, 1500 square feet can be printed per gallon, and the number of wire mesh is t/inch

metal ink 1. In general structures, the substrate surface treatment and coating, pet coating and plexiglass coating are two basic coatings. To achieve ideal adhesion, the material drying temperature is ℉

uv ink must be completely cured

only by understanding the type of substrate can we choose the appropriate one (1) adopt 120t electroslag furnace electroslag remelting smelting and casting to obtain the specification of phi; 1900mm times; 500mm x12crmowvnbn10 ⑴ ⑴ the ink of wheel disc trial parts, and good printing effect can be achieved only by selecting good ink. Therefore, choosing the right ink can achieve the ideal printing effect and best performance. Choosing the right ink is the basis of screen printing. Volatile inks are physically connected, and oxidation and polymerization reactive inks are physically and chemically connected. This kind of ink can be used for thermoplastic adaptations requiring strong solvent resistance, such as PE, which can be appropriately replaced with oil t. Polish can be added according to whether the ink surface needs brightness

paper ink

ink is easy to use and can be used for coated and uncoated paper, outdoor advertising, signs, bottles, signs and cards. It can be divided into two categories: one component and two components. UV ink is different from solvent based ink and evaporative ink. Once the solvent evaporates, the solvent based ink will become a dry ink film; UV compounds include oligomers, monomer polymers and photoinitiators. The disadvantage of water-based reduced UV ink is that it is difficult to operate light-weight paper and porous paper. The most widely used field is mall advertising, especially for paper weighing more than 80bl. If it is less than this weight, the printing paper will wrinkle or curl. Chemical hardeners are used to improve external functions, but if you need to cut, you need to consider the softness of the ink. Ink can be naturally dried, heated and dried

metal pigment ink

when mounting with metal ink, the ink of metal resin must be used

water based reduced UV ink

water based reduced UV ink meets the requirements of solid content and is suitable for uncoated paper. The ink dries naturally for minutes and takes a few seconds to dry

traditional water-based inks

there is little room for the transformation of water-based inks. The storage period is the time to determine whether the material is still useful or beyond the shelf life. Resin inks need to release water quickly without affecting the crosslinking effect of the resin. The folding phenomenon caused by fast water absorption of paper is a common problem

professional silk screen printing can print rich and colorful prints, among which the thick film ink is extraordinary, with good light resistance, wear resistance and printing resistance. It is suitable for printing on all kinds of hard and soft substrates as a whole. It can be used for vacuum molding of shadow plasticity, but its weather resistance and adhesion exposed to light rays and high temperature must be checked. Yinyin bar takes perfect printing service as the main way to display corporate image and spread brand information, integrates printing resources, and establishes an enterprise station. With the help of Yinyin bar and other stations as the media platform, it publishes relevant enterprise soft text and product information on schedule, so as to improve the awareness of peers and consumers of perfect printing

epoxy ink

epoxy ink has good resistance and can be used for all kinds of substrates, such as glass, metal, ceramics, wood, plastic and others. Two component requires adding catalyst or hardener, but it has the advantages of natural drying and baking ink. PS, PVC and PE, PP materials need to choose two different ink series. Other applications: ethylene and metal substrates

uv ink can be sheared, folded, molded, friction resistant, soft, and outdoor weather resistant for up to 5 years. Due to the high water content, the thickness of the solidified film can be slightly reduced, and can be diluted and washed with water. When drying and curing, metal pigments will rise to the surface of the ink and overlap with the ink. This process is called the suspension process of metal particles. Photopolymers react with other compounds, such as monomers. Relying on rich industry experience, Yinyin bar provides business printing and packaging printing. It can be coated with varnish on the metal surface. The coating methods include roller coating, curtain coating, spraying or printing. With UV curing ink, the stability of the ink after mixing is very short. Surface finishing oil helps to protect metal pigments. When the metal color cannot reach the required brightness, the Pearl fluorescent color can be used to replace the metal color, but the hiding power of the Pearl fluorescent color is not as good as that of the metal color. The curing process is completed by the action of photoinitiator, which acts as a connection promoter to connect dispersed molecules and make them polymerize

UV drying of PE materials can be completed in a few seconds. The storage premise of two-component ink is higher than that of one component ink. UV ink has many advantages compared with solvent evaporated ink
