Metal ink, refers to the use of small metal foil instead of traditional inks made of pigments or dyes, with a unique metal shiny effect of the ink. Often said that the metal ink is mainly silver ink and gold ink. Silver ink is made of aluminum pigment; gold ink is generally made of copper pigment and zinc pigment in different proportions, by controlling and changing their ratio can produce green gold, green red gold, red gold ink or the Need Pantone metal color ink.
Metallic ink (metallic ink) refers to the use of metal pigments made of ink, such as gold ink, silver ink.
The following is the basic production process of metal ink: copper, aluminum, zinc raw materials ? melting, atomization ? screening ? grinding ? screening ? pressure filtration ? mixing ? finished with ordinary ink production compared to the largest difference in metal ink production process Is the preparation of metal pigments, especially the grinding process. As the aluminum pigment in the grinding process is easy to explode, it must be wet grinding process. In addition, the metal ink is the use of metal foil particles to achieve the role of reflection of the metal luster, in order to ensure a good mirror reflection effect, the metal pigment grinding process than ordinary pigments to avoid damage to the shape of the metal sheet. In the process of grinding should also pay attention to the choice of additives, the use of different additives can produce floating or non-floating two types of metal ink, the former metal gloss is good, but the adhesion and wear resistance is poor, can not be colored , Although the latter is almost metallic gloss, but the adhesion and wear resistance, especially good coloring. Users should choose floating or non-floating products according to actual needs, which is very critical, otherwise it will affect the post-processing and final product performance.
