A process for manufacturing a layered element comprising the following steps: a) providing a lower outer layer of which one of the main surfaces is textured and the other main surface is smooth; b) depositing a central layer on the textured main surface of the lower outer layer either when the central layer is formed by a single layer, which is a dielectric layer having a refractive index different from that of the outer layer or a metal layer, by depositing the central layer in a conformal manner on said textured main surface 2B, or, when the central layer is formed by a stack of layers (3 1 , 3 2 , ..., 3 k ) comprising at least one dielectric layer having a refractive index different from that of the first outer layer or a metal layer, by depositing the layers (3 1 , 3 2 , ..., 3 k ) of the central layer successively in a conformal manner on said textured main surface ; c) forming an upper outer layer on a textured main surface of the central layer on the opposite side from the lower outer layer , where the lower outer layer and upper outer layer are constituted of dielectric materials having substantially the same refractive index, the refractive index being measured at 550 nm, two dielectric materials having substantially the same refractive index when the absolute value of the difference between their refractive indexes is less than or equal to 0.15, and having different refraction indexes when the absolute value of the difference between their refractive indexes is strictly greater than 0.15, said manufacturing process being characterized in that step b) of depositing the central layer is carried out by screen printing and comprises: b1) positioning a screen-printing screen opposite the textured main surface of the lower outer layer , b2) depositing on the screen-printing screen, preferably using a squeegee, a dielectric layer having a refractive index (n3) different from that of the outer layers or a metal layer. a) providing a lower outer layer of which one of the main surfaces is textured and the other main surface is smooth; b) depositing a central layer on the textured main surface of the lower outer layer either when the central layer is formed by a single layer, which is a dielectric layer having a refractive index different from that of the outer layer or a metal layer, by depositing the central layer in a conformal manner on said textured main surface 2B, or, when the central layer is formed by a stack of layers (3 1 , 3 2 , ..., 3 k ) comprising at least one dielectric layer having a refractive index different from that of the first outer layer or a metal layer, by depositing the layers (3 1 , 3 2 , ..., 3 k ) of the central layer successively in a conformal manner on said textured main surface ; c) forming an upper outer layer on a textured main surface of the central layer on the opposite side from the lower outer layer , where the lower outer layer and upper outer layer are constituted of dielectric materials having substantially the same refractive index, the refractive index being measured at 550 nm, two dielectric materials having substantially the same refractive index when the absolute value of the difference between their refractive indexes is less than or equal to 0.15, and having different refraction indexes when the absolute value of the difference between their refractive indexes is strictly greater than 0.15, b1) positioning a screen-printing screen opposite the textured main surface of the lower outer layer , b2) depositing on the screen-printing screen, preferably using a squeegee, a dielectric layer having a refractive index (n3) different from that of the outer layers or a metal layer. <EOS>
