Ceramic printing ink and glass printing

Ceramic printing can be printed on decals, then transferred to ceramics, printed on ceramics and glass, dried by oxidation or volatilization, calcined at temperatures of 450-1000°C to remove the binder from the ink. . The pigment is solidified on the porcelain and oxidizes to reveal the color.

Ceramic decal printing inks for printing ceramic decals include two parts: colorants and fluxes. Most of the colorants use metal oxides and a few sulphides and selenides. The main components of the mixture are lead and quartz. Borax and boric acid. The proportion of these two varies depending on the color of the metal oxide. The role of the flux agent is to make the metal oxide melt evenly, produce luster, and reduce color. When the ceramic printing ink is overprinted, it should be noted that the same color can be overprinted, and different colors cannot be overprinted, otherwise it will cause chemical changes at high temperatures, resulting in coloration and bursting of flowers. Spot colors are also used in printing, and colors are not mixed with the three primary colors.

Glass printing ink

Glass printing inks are printed in various forms primarily by screen printing methods. A paste colorant consisting of three components, a ceramic pigment, a glass powder, and a binder. After printing and curing, it was baked in a heating furnace at 600°C to vaporize the linking material. The pigment was transferred from the molten glass powder to the glass for printing glass bottles, cups, and plates. The ceramic pigments used were titanium oxide {white}, cadmium yellow (yellow), cadmium red (red), cobalt blue (blue), chromium oxide {green}, cobalt green (green), and ferric oxide (brown). The glass powder is mainly composed of silica, lead oxide, and boron oxide, and is often accompanied by other gold oxides to reduce the softening point and improve the resistance performance. The linking material contains hydrogenated rosin ester, pine oil, etc., and is vaporized before the glass is melted to prevent carbonization of the ink layer. Another type of glass printing ink is melted when heated to 70-80°C, has a certain viscosity, can be screen printed, cured at room temperature, and used for printing glasses and beverage bottles. Epoxy-type two-component inks are commonly used in screen printing small glass containers (such as cosmetics bottles, ashtrays). The commonly used one-component epoxy inks can be touch-dried after 10-15 minutes of printing, but they must be baked at 180° C. for 10 minutes to form a stronger ink film.
