Abstract
A method of creating images in stone substrate such as granite monuments using digital laser etching into a painted area. Alternatively, two layers of color contrasting coatings may be applied and the laser etching penetrates into the innermost layer to produce a contrast with the top coat. Pigmented material of a chemical content which is related to the mineral content of the substrate. Various enhancement techniques are also described.
Claims6
A method of creating an engraved image on a surface of a stone substrate, the molecular content of which includes silicon and oxygen, comprising the steps of:
- digitizing an image;
- defining an image-receiving area on the surface of said substrate;
- coating the image-receiving area on said surface with a breathable primer having a chemical content including silicon and oxygen compatible with the mineral content of the substrate;
- overcoating the primed area with a first pigmented, durable polysiloxane paint of a first color and having a chemical content related to the mineral content of the substrate and the primer;
- using the digitized image, laser etching an image into the overcoated area by creating a digital pattern of blind holes of uniform depth in the overcoating paint and into but not beyond the primer;
- overcoating the etched area with a polysiloxane paint of a second color contrasting to the first color to fill said blind holes;
- and
- sealing the image area.
A method of creating an engraved image on the surface of a stone substrate wherein the molecular composition of the stone contains components of silicon and oxygen and wherein the method comprises the steps of:
- digitizing an image;
- defining an image-receiving area on the surface of the substrate;
- coating the image-receiving area with a primer having a chemical content including components of silicon and oxygen so as to be compatible with the substrate material;
- applying a polysiloxane paint over the primer and having a first color;
- applying a second polysiloxane paint over the first color layer and having a color which strongly contrasts with the color of the first polysiloxane paint;
- using the digitized image, etching a digital pattern of holes of uniform depth through the second polysiloxane paint layer and into the first polysiloxane paint layer thereby to create a reproduction of the digitized image;
- and, thereafter,
- sealing the image area.
