  • Patent number: 5193457
    Abstract: To print on a glass sheet (42) with an edge-flush peripheral decorative frame (43, 45) the printing of decorative frame (43, 45) takes place with a silk-screen printing process in two printing operations, in which two partial areas (43, 53) of decorative frame (45) complementary to each other are printed consecutively. In the first printing operation a first partial area (43) of decorative frame (45) is aligned along two adjacent edges flush with corresponding glass sheet edges (46, 47), and in the second printing operation a second partial area (53) of decorative frame (45) is aligned edge-flush with the two other glass sheet edges (48, 49). The two partial areas (43, 53) of the decorative frame complementary to each other mutually overlap by measurement (D), which corresponds to the area tolerances of the glass sheets.
