A transparent or translucent glass-ceramic plate, capable of covering or receiving at least one underlying heating element. The plate has a coating which at least partly masks the underlying heating element(s), while still allowing the heating element(s) and optional displays to be detected. At least 90% of the coating is on the face of the plate to be turned toward the heating element(s) and optional displays in the use position. The coating has a region or a group of regions known as a background region(s), wherein the background region(s) occupy most of the surface of the coating. The coating also has a region or a group of regions known as indicating region(s), wherein the indicating region(s) making it possible to display, relative to the background region(s), a pattern, a sign and/or the location of functional elements while also making it possible to detect if the elements are in operation.
