Because the main raw material of spot color printing gold ink is brass powder, it is a chemically active metal, which is prone to discoloration after exposure to air. Therefore, we should pay attention to the following situations when printing gold ink: 1. If gold ink comes into contact with acids, alkalis, carbon and sulfides, it will produce different degrees of chemical changes, reduce the gloss of the metal, the gold ink will look black, and the gold ink should be avoided for printing on large areas. The paper produced by the acid papermaking process is acidic. After printing, the gold ink not only changes color, but also loses gloss. 2. The use of gold ink should master the principle of printing with adjustment, that is, the amount of one preparation should be suitable for continuous printing for about 3 hours, so as not to adjust too much to make the gold powder in the oil for a long time, or contact with the air for a long time to oxidize Spoils and loses its golden luster. 3. The speed of gold ink printing should not be too fast, because the frictional heat of the ink roller will increase correspondingly due to the fast speed of the machine, which will easily make the gold ink oxidize and blacken. Therefore, the speed of printing gold should be controlled at about 3,000 sheets / hour. 4. The semi-finished products of printing gold ink should not be stacked too much, otherwise the heat released by the gold ink during the drying process on the paper surface cannot be dissipated as soon as possible, and the gold ink will be oxidized and discolored. 5. If gold ink is printed on the background color, care should be taken to properly add dry oil to the background color to avoid overprinting the gold ink when the background ink is not dry, which will affect the gloss color of the gold ink.

Top&Top Printing Packing Co.,ltd is specialized on printing and packaging for more 10 years.And we are proficient in various printing technologies,mainly product is cosmetic packaging box,paper shopping bags,children board book printing.Here ,we introduce normal printing . Lithography The lithographic printing plate is flat and uses the principle of water and oil immiscibility to achieve printing. The printing plate is divided into a lipophilic and hydrophobic graphic portion and a hydrophilic and oleophobic blank portion. In this way, the graphic portion absorbs the ink, and the blank portion does not adsorb the ink. Copy and transfer of graphics and text are done by the imprinter. Lithographic printing is indirect printing, the graphics on the printing plate are first transferred to a cylinder, and then the graphics and text are transferred to the printing material by the inked blanket cylinder. Rolling has good hydrophobic and lipophilic properties, which can fully transfer the ink and limit the transfer of moisture. In addition, the blanket cylinder is elastic and can withstand large printing pressure to ensure the correct transfer and transfer of graphics. Lithography can be multi-colored and colorful. The printing format is large, and the color of the finished product is saturated, with less noise and smudges. The screen is flat. In this respect, it is better than other printing methods. Lithography occupies the largest market in various types of printing in China. Offset printing that designers often contact is Lithography occupies a dominant position in the printing industry. Relief Printing The printed part of letterpress printing is higher than the blank part, and when all printed parts are printed on the same plane, apply ink to the printed part. Because the blank part is lower than the printed part, the ink cannot be adhered. The printing plate is contacted, and a certain pressure is applied to transfer the ink of the printing portion on the printing plate to the paper to obtain a printed product. Since the blank portion is concave, the blank portion on the printed matter is slightly protruded when pressed to form a printed product. The surface has inconspicuous unevenness. Gravure printing The printing plate of gravure printing is lower than the blank part, and the degree of depression changes with the level of the graphic. The darker the graphic level, the deeper the depth, and the blank part is on the same plane. When printing, After the ink is applied on the entire layout, the ink on the flat surface (ie, the blank part) is scraped off with an ink scraping machine to keep the ink only on the printing plate with a low concave surface, and then a substrate with strong ink absorption is placed on the surface to apply Under high pressure, the ink on the printing portion of the layout is transferred to the substrate, thereby obtaining a printed matter. Because the depth of the depression of the printing portion on the layout is dif...

According to the design requirements, specific paper and materials are processed and manufactured on a machine equipped with a steel knife stencil, and the paper or material is die-cut into the required shape and presents special effects in form. This process technology is called die cutting. The specific paper and materials are processed and manufactured on a machine equipped with a steel wire template according to the design requirements. The surface of the paper or material is printed with deep or shallow steel wire traces under pressure, and then folded by hand or machine. The paper And materials are easy to bend and form a certain form of structure or shape. Such a process technique is called indentation. Generally, the die-cutting and creasing process is a process of combining a die-cutting knife and a creasing knife in the same stencil, and simultaneously performing die-cutting and creasing processing on a die-cutting machine. It is often referred to as die cutting or stamping in daily production. It can be operated as a separate process or two processes can be combined into one process on the same machine. The die-cutting plate is equipped with both a steel knife and a steel wire without conflict. The die-cutting and indentation process changes the single straight or flat form of the printed matter, and allows various printed packaging to be presented in three dimensions and curves. The various shapes and shapes created are more beautiful and delicate, and are full of creative and intelligent printing packaging product. In the field of paper prints, die-cutting and indentation processes are widely used, such as common packaging cartons, special-shaped tags, hollow labels, folding DM bills, stickers, leather products, etc. Cut craft. Common three-dimensional packaging boxes such as cuboids, cubes, cones, and polyhedrons. Flat works of various shapes, such as circles, ovals, plum blossoms, polygons, etc., and other special creative graphics that appear in book albums in combination with a page design.
