    Abstract: The present invention relates to a process for manufacturing a glass panel providing a one-way vision function and comprising one or more discrete enamel patterns composed of a plurality of layers that are exactly coincident, characterized in that: a) at least one oxide-based protective layer of a thickness larger than or equal to 10 nm is deposited on the glass substrate; b) at least two layers of different compositions are deposited on the protective layer, the composition of one of these layers containing at least one mineral pigment and being free of glass frit, the composition of the other being an enamel containing at least one glass frit and at least one mineral pigment of colour different from that of the layer free from glass frit, the layer free from glass frit being deposited on all or some of the surface of the panel and the enamel layer being deposited by screen printing in the form of the desired pattern(s); c) the panel coated with said layers is heated to a temperature high enough to bake the enamel; and d) the pigments not held in place by the enamel, i.e. those located beyond the pattern(s), are removed, the particles of pigment(s) and the particles of the glass frit(s) being of similar size and especially having a particle size distribution such that 50% of the particles are smaller than 7 µm in size.
