Printing
Printing is the process of transferring text, images, or patterns from a master form to a receiving surface. The master form can be made of a variety of materials, including wood, metal, plastic, or even paper. The receiving surface can be paper, cloth, or another material. -

UV flexo Printing Technology
UV flexo printing originated from label printing. At first, low-speed narrow web rotary printing machines were mostly used to print self-adhesive labels, and a 300W/line inch medium-pressure mercury vapor lamp was used to obtain a satisfactory curing effect. -

What is low migration ink and what are its characteristics!
After the ink is dried and solidified on the substrate to form an ink layer or ink film, due to friction, ink layer not fully cured, poor adhesion, etc., it is transferred to other places through contact or scratching, causing pollution, which is called "Ink Migration". -

Precautions for spray powder? Do you know several points?
Powder coating is to use powder spraying equipment (electrostatic spraying machine) to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is baked at high temperature. Bake leveling and curing, and become the final coating with different effects (different types of powder coatings); the spraying effect of powder spraying is better than that of spray painting in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also higher. Under spray paint with the same effect. -

Advantages and Disadvantages of UV Print, Five Main Components of UV Print
UV paint refers to ultraviolet light curing paint, also known as photoinitiated paint, light curing paint, uv paint is named after the curing method of paint, and is a new type of paint product widely used in modern industrial industries. It is automatically rolled and flow-coated on the furniture board/paper by machinery and equipment, and the initiator is decomposed under the irradiation of ultraviolet light (wavelength: 320-390nm), which generates free radicals, triggers resin reaction, and instantly solidifies into membrane. -

Production Method of Optical Variable Ink
Optically variable inks were first used in the anti-counterfeiting printing of banknotes, checks, bonds and other securities. With the continuous development of science and technology, optically variable inks are not only used for anti-counterfeiting printing of trademarks, but also for surface decoration of special products. The reason why the optically variable ink has the corner-changing color characteristic is that a pigment with a very special structure is used, and its particles are very thin flakes with a good particle size distribution. The production process of the pigment is as follows: under high vacuum conditions, according to the design requirements of a specific film structure, a variety of materials with different refractive indices are sequentially deposited on the same carrier to form an optically variable film, and then undergo crushing, grading, surface treatment, etc. . When the thickness of the film layer meets the interference conditions of light, the film layer will show a photochromic effect, that is, its color will change as the viewing angle of the human eye changes.
