Photogravure ink design (in)

The five major parts of gravure ink constitute one another, which restricts each other and influences each other. Only adjuvants may be used as little or as little as possible in some circumstances. However, according to the trend of modern ink-jet technology, a lot of production focus has shifted to the study of adjuvants, because although it is used in small quantities, it can often receive larger modification effects. The solid resin is selected according to the requirements of the printing object; the solvent is selected according to the resin properties and the dryness requirements; the pigment (dye) is the only sign of decorativeness, because its coloring method is that the particles (molecules) are arranged to cover the surface of the object. A distributed medium is needed. Although the filler is used to supplement the amount of solids and adjust the thinness, it does not affect the color and saves costs. Such inks are still being continuously improved and developed. Table 1 lists the currently used five types of gravure inks, and Table 2 lists the uses of these five types of gravure inks and the resins used.

At present, these kinds of gravure inks exist at the same time, but the benzene type tends to be eliminated, and the mixed solvent type and alcohol type are mostly. The water type has not been long in China since 75 years, but the yield development is still acceptable.

The above is mainly based on the composition of the solvent to distinguish, but also according to the use and characteristics to distinguish, such as: paper gravure ink, plastic gravure ink, film gravure ink, high-light gravure ink, flex-resistant flexible gravure ink and so on.
