Introduction To Printing Inks

    Ink is used in the printing process for the formation of graphic information of the material, so the role of ink in the printing is no trivial matter, it directly determines the image on the print tone, color, clarity and so on. In the printing we need to understand the composition of ink and ink classification. The ink should have a bright color, good print adaptability, and suitable drying speed. In addition, it should also have a certain solvent, acid, alkali, water, light, heat and other aspects of application indicators. With the printing, paper and other requirements are getting higher and higher, the technical requirements for the ink also increased. Such as modern high-speed multi-color printing presses and various color rotary presses, require ink to dry at a rate of a few seconds or even faster. Glass cards and gold, silver cards, coated paper require bright ink. Printing plastic film, requiring good bonding with the plastic film; or the maximum adhesion with the plastic film attached to the ink. Printed special print, require the use of photosensitive ink and so on.Printing Ink

    The ink is mainly used in the printing industry. Pigments and linkers are two main raw materials that make up the ink. When the operator chooses the ink, the color is generally regarded as the first requirement. The color of the ink (hue) is one of the most intuitive indicators. In fact, it is a major indicator of the quality of the printed material to a large extent. So the pros and cons of the pigment, the ink is good or bad is to play a decisive role. Printing Ink

    Pigment is a solid powdery substance that is neither soluble in water nor soluble in oil or binder. It is not only the main solid part of the ink, but also printed on any object visible chromosome part. To a large extent determine the quality of the ink, such as color (hue), thin thick and so on. On the viscosity, physical and chemical properties, printing performance, etc. have a great impact. Thus, the pigment is required to have a bright color, a high concentration, good dispersibility, and other related properties required for the ink. In fact, the perfect paint is not perfect, can only be relatively or partially satisfied.Printing Ink
