Common Gravure Printing Faults and Treatment Methods         Rotary high-speed gravure printing machine has the characteristics of high production efficiency, rich graphic performance, good sense of hierarchy and strong three-dimensional sense.Common Gravure Printing Faults and Treatment Methods        It is widely used in mass printing, especially in cigarette package printing. As several major elements of gravure printing – paper, printing plate and ink, when any one of the printing environment can not meet the use requirements, different printing faults will occur and the production can not be carried out.Common Gravure Printing Faults and Treatment Methods Overprint fault:           Overprint overall fluctuation: mostly caused by unstable tension. First, it is caused by the failure of the automatic tension control system of the equipment, such as improper tension setting, damage of mechanical transmission parts, damage of PIV gearbox bearings, etc; Common Gravure Printing Fau […]

On Anti-Counterfeiting Ink         Anti counterfeiting is a highly technical industry. Its market is closely related to technology, and the whole market has many subdivided fields. Different commodities and different use environments need different anti-counterfeiting technologies. On Anti-Counterfeiting Ink       No anti-counterfeiting technology is suitable for all anti-counterfeiting fields. This paper will briefly introduce the anti-counterfeiting technology based on ink.On Anti-Counterfeiting Ink          Anti counterfeiting ink, that is, ink with anti-counterfeiting performance, is an extremely important anti-counterfeiting technology field, which has a wide range of applications and involves many disciplines.On Anti-Counterfeiting Ink        Anti counterfeiting ink is a special ink with anti-counterfeiting function generated by adding some special substances to ordinary ink. On Anti-Counterfeiting Ink        I […]

Color Essentials of Packaging        The color on packaging is the most active factor affecting vision, so packaging color design is very important.Color Essentials of Packaging Whether the overall feeling of packaging color is gorgeous or simple depends on the total tone of packaging color.Color Essentials of Packaging        The total tone is embodied directly according to the basic color attributes of hue, lightness and purity. Such as bright tone, dark high tone, fresh tone, gray tone, cold tone, emphasis, weak tone, soft training, hard tone, heavy tone, etc.Color Essentials of Packaging        In addition to hue, lightness and purity, color area is an important factor that directly affects hue. Color matching first considers the arrangement of large-area color, which has a long-distance visual effect in packaging and display. In addition, when the contrast between two colors is too strong, the area of one color can be expanded or reduced wit […]

Blending of Gold and Silver Ink       When using solvent ink, silver ink is more stable than gold ink, and the printability is better than gold ink. When using water-based ink, because aluminum powder is lively and easy to form oxide film on the surface, hydrogen will be released by interaction with water.Blending of Gold and Silver Ink       which will affect the stability of color paste, so it is not as common as gold powder printing in practice.Blending of Gold and Silver Ink       In order to ensure the purity of ink, when printing gold and silver ink in the last pass, wet the mesh with 783, clean the layout, and then apply ink after the solvent is completely volatilized. Because when gold and silver ink encounter some uncertain factors, they will react and cause ink discoloration.Blending of Gold and Silver Ink  Blending of Gold and Silver Ink            Due to the poor fluidity of gold and silver ink, ink blending oil or slow drying ag […]
