Color Matching Techniques For High Temperature Glass Inks

High-temperature glass ink color matching, printing will be used, with a certain degree of technical and technical skills, especially color ink color matching and other ink color matching is more special, which involves a variety of materials. In the color matching process, metal pigments, ordinary pigments, pearlescent pigments and dyes may be added at the same time, so high-temperature glass ink color matching work is much more difficult than other conventional color matching.
High temperature glass ink as a chemical product, there will be some unstable factors. Because of the chemical structure, solvent resistance, resistance to transportability, solubility, polarity, acidresistance, alkaline resistance, different proportions of different reasons, different customer use conditions are different, construction methods and processes are different, stirring uniformity is not the same, coloring inks will often appear some common problems.
In order to avoid this problem and reduce the frequency of occurrence, it is necessary to pay attention to the following aspects when using high temperature glass ink to tone color:
1, in the selection of high-temperature glass ink, should first understand its performance, as far as possible to choose all aspects of performance are better products, especially in terms of permeability more weight.
2, when tining, try to choose similar colors to similar products, with the fewest varieties to call out the required phase. The more varieties you choose, the worse the viability, the less stable it is, and the more likely it is to produce discoloration.
3, high temperature glass ink color adjustment as far as possible to choose the original color for deployment, to avoid the use of intercolor for blending.
4, adjust the product placed after a period of time before use, need to stir evenly, after detection of color stability before printing.
5, choose the same brand of the same series of products to use, to avoid the ink difference, ink reaction between the resulting ink quality variation or discoloration.
6, in the addition of metal pigments and pearlescent pigment color, not only to consider the choice of these materials of the color, more important according to the actual requirements to choose the same particle size and flash of metal pigments and pearlescent pigments. At the same time, when selecting metal pigments, we should take into account the general characteristics of metal pigments, fineness and baidu and flash relationship. Because the pearl pigment is a multi-angle reflective pigment, so in the high temperature glass ink color matching should pay attention to the color printing after different angles of color color.
