Screen printed directly in the glass on the glaze application technology
Glass printing ink
Screen printing on glass, engraving and printing screen printing with the General the same. Glass printing features in the printing ink. Glass printing ink is composed of three components:
(1) easy melt glass material. Ink used to make glass glass is usually made up of silica, composed of three boron oxide, lead oxide and aluminium oxide.
(2) glass paint. Glass printing immobilization syndrome must be through high heat sintering to paint on glass, therefore no pigment ink with organic pigments, can only use inorganic metal oxides. Once through high heat sintering, integrating these metal oxides and glass, glass is on the color. Commonly used inorganic pigments for glass printing ink are as follows:
Cadmium sulfide red; yellow lead chromate, cadmium sulfide, uranium salts;
Chromic oxide green; blue aluminum drill;
Brown iron oxide and calcium oxide, kaolin, white.
Black Iridium oxide, manganese oxide mixture;
Colour variations are endless on the screen, the transition in order to display a variety of different hues and values of different brightness, often multiple color adjustments.
Fusible glass with glass paint to mix and grind to a fine powder can be used as ink, also called powder glass glaze powder.
(3) the varnish. Varnish is glass ink binders. It consists of terpineol, turpentine, adding appropriate alkyd resin distribution. Inking oil and have a certain degree of mobility, glass glaze powder can spread very well, has a good printability, on the sintering in the glass before the glaze melt, gasification burning clean, does not adversely affect the formation of glaze.
