Definitions

  • the present invention relates to the field of etching on a hard material and more particularly on rock substrates which will be conventionally called “supports" in the context of the present invention.
  • the invention relates more precisely to the engraving on the surface of a support, of a design for decorative use or of instructions "in relief in savings size”; reproduction process where the so-called “clear” areas of the drawing are hollowed out and where the areas which must come in "shadow” are spared.
  • a first evolution of this classic engraving technique is the so-called "sandblasting" technique.
  • This technique uses a mask covering the surface of said support to be decorated to protect the shadow areas of the drawing to be reproduced, from the stripping effect of the sandblast which wears out the unprotected parts. It therefore follows that the parts protected by said mask define on the surface of the support, the shadow areas and the unprotected parts define the light areas.
  • the method of reproduction by engraving on stone of the invention offers a great advantage insofar as the contours of the above geometric unitary patterns can be obtained by industrial techniques particularly indicated for mass production.
  • the method of reproduction by engraving of the invention therefore consists in tracing recessed on the surface of said support of the lines so as to delimit a frame of small squares, small rectangles, small triangles, etc ... Then, just remove the squares, rectangles or triangles corresponding to the light areas of the design for decorative use so as to leave space on the surface of said support only the squares, rectangles or triangles marking the shaded areas.
  • the tracing operation of the lines can be mechanized by a disc cutter whose different displacements parallel to the surface of the support on the one hand, and the depth of penetration of the disc on the other hand, are controlled, even automatically chained, according to pre-established programs of computer control.
  • the preset program makes it possible to configure the subdivision of the geometric unitary patterns according to data recorded by the engraver.
  • an automatic adjustment of the penetration depth of the cutter disc in the hard material of the support has the great advantage of being able to subdivide into geometric unitary patterns, both the flat surface and the curved surface of the support on which evolves the disc debtor.
  • the parts circumscribed around holes dug in the shape of a circle can be kept in relief, by drilling or by any other equivalent technique leading to the same result.
  • the reproduction of a design for decorative use on the surface of a block of granite for example, according to the engraving method of the invention can therefore be akin to the analytical reproduction of an image by points, a technique well known in the field of IT and printing.
  • the advantage of the invention lies in the fact that this point technique is used in three dimensions. Consequently, the contrast "shadow-light", at the base of any drawing for decorative use, is amplified by the lighting which leaves in the shadow two or three of the four side faces of each cube of the geometric unitary patterns when these are squares. Therefore, if the light source is subjected to a precise trajectory which is the case of the sun, the "shadow-light” contrast modifies the visual perception of the image of the drawing reproduced according to the engraving method of the invention. In fact, your path of the sun between sunrise and sunset changes the shaded areas.
  • Another advantage of the invention lies in the fact that nuances can be given for the same design with the etching process of the invention.
  • the depth of the hollows will also be adapted to the dimensions of the surface of the decorative unitary patterns to play on the lateral faces of said shading patterns.
