The invention realates to a ceramic tile provided with a decor caused by means of light effects obtained by passage of light through an at least partially transparent material with a system of arranged formations. The tile is provided with a transparent material, preferably a tile glaze (3). A front printing (5) is provided on the face side of said tile glaze (3) and a back printing (6) is provided behind the back side of said tile glaze (3). The printings (5, 6) are formed by a plane raster containing parallel lines and slits or characters grouped into formations with slits between them, whereby the number of said formations of said back printing (6) and of said slits of said face printing (5) differ and the prevailing direction of formations of said rear printing (6) is to more than 50 % identical with the direction of the slits of said face printing (5). The present invention produces printed decors on hard, at least partially transparent materials, so as on glazes of ceramic tiles in a wide variety of patterns and colour in a simple way and at acceptable costs.

Cette invention a trait à un carreau de céramique dont le décor est assuré par des effets lumineux dus au passage de la lumière à travers un matériau au moins en partie transparent avec un ensemble de motifs agencés. le carreau comporte un matériau transparent, de préférence un glacis (3). Le côté face de ce glacis comporte une impression frontale (5) tandis qu'il est procédé à une impression en transparence (6) en arrière de l'envers de ce glacis (3). Les impressions (5, 6) sont formées par un canevas plat renfermant des lignes et des fentes parallèles ou des caractères groupés en motifs séparés par des fentes. Le nombre des formations de l'impression en transparence (6) de l'envers du glacis (6) et des fentes de l'impression frontale (5) est sujet à variations et la direction prédominante des motifs de l'impression en transparence (6) est à plus de 50 % similaire de la direction des fentes de l'impression frontale (5). Il est possible, dans le cadre de cette invention, de produire des décors imprimés sur des matériaux durs au moins en partie transparents, notamment sur des glacis de carreaux céramiques, et ce, avec une grande variété de configurations et de couleurs, facilement et à des coûts de revient admissibles.
