<p>A novel glass ceramic plate (I) has a coating (II) on at least one zone of one face such that (a) the total color deviation (delta E*) (measured from the opposite face) between the coated and non-coated zones is less than 1 and/or (b) the luminosity (L*) of (II) is more than 70 (preferably 70-90). An independent claim is included for the production of (I), by applying the coating (II) (preferably by silk-screen printing) to at least one zone of one face of a glass precursor plate before ceramization or of a glass ceramic plate, optionally followed by drying and/or stoving of the coating, such that the colorimetric property/ies (a) and/or (b) is/are attained.</p> |
