A method for manufacturing a motor vehicle roof incorporating a glazing, in which at least one opacifying layer of ink(s), in particular at least one layer of colored ink(s), is applied by digital printing, in particular by inkjet, over at least 40% of the surface of one of the faces of at least one glass sheet, such that the composition of said ink(s) includes at least one glass frit, and where applicable one or more inorganic pigment(s), with a D90 value for the particle size distribution of less than 2 μm, and such that the ink(s) have a viscosity of between 1 and 50 mPa·s, the ink(s) further including a non-stick agent and/or a non-stick component and/or at least one non-stick agent and/or at least one non-stick layer being further applied to at least one layer of ink(s) and/or to at least one glass sheet.

A luminous glazing assembly includes a first glazing pane with a first light source coupled to the first pane to emit at instant tat &#x3bb;and to emit at t'&#x2260;tat &#x3bb;distinct from &#x3bb;; a first light-extracting system and first masking arrangement to mask the extracted light from the internal-face side; making optical contact with the first glazing pane, a second glazing pane with a second light source that is optically coupled to the second pane, to emit at tat a &#x3bb;distinct from &#x3bb;; a second light-extracting system and second masking arrangement to mask the light from the bonding-face side; between the first masking arrangement and the second extracting system, a first optical isolator; and between the first masking arrangement and the second extracting system, a second optical isolator, merged with the first optical isolator or separate and closer to the second extracting system.

A process for manufacturing a one-way vision glass pane, the process including: a) depositing a layer of a compound comprising a mineral pigment over an area of the pane, the compound being free of glass frit; b) depositing a layer of an enamel compound including a glass frit and a mineral pigment of a different color to the pigment of a), by screen printing, in the shape of the one or more desired patterns; c) heating the coated pane to a temperature high enough to bake the enamel; and d) removing pigments that have not been fixed by the enamel, wherein the particles of the pigments and the particles of the glass frits are of similar size, and the thickness of the layer of the deposited enamel compound is larger than the thickness of the pigment layer deposited in a).
