What Exactly Is The Printing Ink In The End?
The ink should have a bright color, good print adaptability, and proper drying speed. In addition, it should also have a certain solvent, acid, alkali, water, light, heat and other aspects of application indicators.Printing Ink
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.
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.Printing Ink
In fact, the perfect paint is not perfect, can only be relatively or partially satisfied. The binder is a glued fluid. As the name implies, it is a link. In the ink industry, is the powdery pigments and other substances, mixed together, so that after the dispersion in the grinding, it is possible to form a certain degree of fluidity of the slurry adhesive.
Printing ink, printing ink Atlas, the link material is the ink in the fluid part. Ink flow (sex), viscosity (sex), dry, and printing performance, etc., are dependent on the link material. Therefore, the link material is the basis of good or bad ink quality. All kinds of vegetable oil, mostly used to make ink link material. Some animal oils, mineral oils are also used in the ink binder. Solvents and water are no exception.Printing Ink
In recent decades the emergence of various resins, expanding the source and variety of materials.
Fill (charge) material is white, transparent, translucent or transparent powder material, but also the solid parts of the ink. Mainly from the filling effect. In the ink is filled with paint part. Appropriate use of some filler, can send to reduce the amount of paint, reduce costs, but also adjust the nature of the ink, such as thin thick, mobility and so on. But also improve the flexibility of formula design. Additional material. It is not difficult to understand that the additional material is an additional part of the ink other than the primary composition. They may be an additional part of the pigment, an additional part of the material, or as an additional part of the finished product, depending on the characteristics and requirements of the product.
Of course, a lot of additional material is printed (auxiliary) additives.
At present, the world's raw materials for the manufacture of ink up to five thousand or so.
