Coated glass or glass ceramic article

A method for producing a glass or glass ceramic article, comprising the steps of:

• providing a sheet-like glass or glass ceramic substrate having two opposite faces, the substrate exhibiting light transmittance in the visible spectral range from 380 nm to 780 nm of at least 1% for visible light that passes across the substrate from one face to the opposite face;
• providing an opaque coating on one face of the substrate, the opaque coating exhibiting light transmittance of not more than 5% in the visible spectral range;
• directing a pulsed laser beam onto the opaque coating to locally remove the opaque coating by ablation down to the face of the substrate, repeatedly at different locations, thereby producing a pattern of a multitude of openings defining a perforated core area in the opaque coating so that the opaque coating becomes semi-transparent in the perforated core area;
• and
• directing a pulsed laser beam onto the opaque coating to locally remove the opaque coating by ablation down to the face of the substrate, repeatedly at different locations, thereby producing another pattern of a multitude of openings defining a transition area along a periphery of the perforated core area in the opaque coating, the transition area having an ablated percentage surface area that is lower on average within the transition area than within the core area, the ablated percentage surface area being defined by a ratio of ablated surface area to non-processed surface area.
