Abstract: An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.

Abstract: A horological component including a substrate and at least one first decoration component including at least one first photoluminescent material configured to procure a phosphorescent appearance. The horological component includes a second decoration component including at least one second material, the second material being metallic and configured to procure a metallic appearance, or variochromic and configured to procure a color that varies under the effect of a stimulus, the first decoration component and the second decoration component being arranged relative to one another on the substrate to form a decoration having a metallic appearance or a color that varies under the effect of a stimulus when the horological component is exposed to light and a phosphorescent appearance when the horological component is in the dark. A timepiece can include such a horological component.
