    image 1 DESCRIPTION
    Method for decorating a transparent material Object of the invention
    The present invention relates to a method of decorating a transparent material, including an image produced by internal or external laser engraving, on which a high temperature heat setting digital ink print is applied. State of the art
    Glass is a transparent material that can be laser engraved, so that light reaches points outside or inside the piece of transparent material such as glass,
    10 extra-clear glass, optical glass, methacrylate or similar characteristics, so that the engraving of the transparent material is achieved, by which images engraved inside or on an external surface of the glass are obtained.
    The development of increasingly powerful and precise lasers have allowed the achievement of artistic results, as is the case of laser-engraved crystals for printing
    15 of two or three-dimensional images or glass photographs.
    A high precision laser engraves one by one all the points that make up the three-dimensional image of an image as a portrait. Just as a two-dimensional image on paper is made up of countless individual dots, pixels, which when viewed together form a clear and sharp image, a 3D portrait is also made up of many dots.
    20 individual ones that are transferred inside the glass, so that each point has a position in space, and not only in a single two-dimensional plane but in different planes of space, giving the photo the desired relief.
    To record each point in the image, the laser beam is focused by a lens at a point where all the laser energy is concentrated, burning the material onto which the laser beam is applied. Since the glass is transparent, the laser can be focused on any part of it, either on the surface or inside, since the light beam penetrates into the transparent material, recording the target point. The crystal remains
    image2
    always in one piece, it is simply engraved inside the transparent material.
    The area engraved on the glass is rougher and more opaque than the area without engraving due to the alterations that the glass undergoes under the concentrated action of the laser when creating the image. The image is created using opaque dots; that is, on a gray scale within the
    5 transparent material. A 3D image made using a reduced number of dots forms a more transparent and ill-defined 3D image.
    There is a need to enhance the artistic value of the engraved image within the transparent material with or without relief, without reducing the beauty of the glass used for decorative purposes. 10 Summary
    The present invention seeks to solve one or more of the drawbacks discussed above by a method of decorating a transparent material, including an image produced by laser engraving, on which a print of heat-fixed inks is applied as claimed in the claims.
    A method of decorating a transparent material with a first two or three-dimensional image produced on the transparent material by laser engraving; where a second color image is printed on a printable outer surface of the transparent material by means of a printer, and then the printed transparent material is introduced into a high-temperature oven to permanently heat fix the
    20 second image printed to the printable outer surface by applying heat directly to the outer surface of the transparent material.
    The engraved and printed transparent material is insertable inside a hole made of a hard and resistant material such as stone, natural stone, artificial stone, ceramic, porcelain, or similar characteristics, to form an artistic object for outdoor use. The hollow
    The hard material is made using the water jet cutting procedure. Next, the transparent material inserted into the hollow of the transparent material is attached thereto by chemical means such as polyurethane.
    The printing process is done using a digital printer and the cooking process is done using a high-temperature oven that supplies heat directly to the second image printed on the printable surface of the internally etched glass.
    image3
    The required cooking temperature and cooking time are selected based on the properties of the inks or dyes used to print the second image on the glass surface and the physical dimensions of the glass itself, the second image being permanently fixed by heat on the glass surface.
    The transparent material is of the glass, extra-clear glass, optical glass, methacrylate, plastic material, or similar characteristics and is suitable for coloring.
    The visible art object for outdoor use is a gravestone on which it has been assembled
    10 the transparent material with a first two or three dimensional image produced by laser engraving and a second image printed on an outer surface of the transparent material. In case of being the first three-dimensional image, the transparent material is internally laser engraved below the surface of the transparent material itself.
    The engraved and printed transparent material is clearly visible and provides
    15 spectacular results with high reproduction accuracy and a photographic appearance finish. Furthermore, the glass is hard and does not scratch easily and, on the other hand, the glass retains its properties during its life. Brief statement of the figures
    A more detailed explanation of the invention is given in the description that follows and is based on the attached figures:
    Figure 1 shows on a block diagram a method for decorating a transparent material which is attached to a hard material. Description
    The purpose of the procedure is to decorate a transparent material, on which it has been engraved
    Previously a first image produced by internal or external laser engraving, with a second multi-color image to provide a decorative item for use on gravestones.
    image4
    The tombstone, which includes transparent decorated material, is adapted to be used outdoors. In other words, the headstone has its application in the mortuary industry, its use not being ruled out for other types of artistic developments. The material is mounted on the design headstone
    5 transparent decorated with a decorative element selected by a customer who has decided to select for the headstone.
    The transparent or support material is a material of the crystal, extra-clear glass, optical glass, methacrylate, plastic material or similar characteristics, suitable for engraving inside the same with a laser. The engraving of the crystal is carried out by focusing a 10 laser beam inside the material, so that near the focus, a very high temperature will be reached for an instant. After cooling, an opaque, grayscale dot remains on the glass. To make the first image, the laser focus moves through the material creating thousands of gray or opaque dots. The first image formed can be bi
    or three-dimensional.
    15 External or internal laser engraving acts at any depth of the material. Therefore, the crystal must be essentially transparent to the irradiated laser radiation, since otherwise it would be absorbed in the surface area of the crystal. Internal laser engraving of the crystal with a laser beam presupposes a weakening of the crystal. Therefore, efforts should be made to keep this impairment as small as possible.
    The production of laser engraved crystal is carried out in a known manner according to the techniques and procedures that are common in the preparation and processing of internally laser engraved crystal.
    Next, the glass engraved with the first two or three-dimensional image selected by the customer, goes to a printing stage to generate a second color image on
    25 a printable surface of the pre-etched glass.
    The printing step is carried out by means of a digital printer which prints, on the printable outer surface of the engraved glass, the second image such as a decorative color motif. That is, the digital printing process provides a second multi-color image on the printable surface of the etched glass.
    image5
    The full-color digital printing process is governed by a computer running a computer program that directs the digital printer to print the second image or any type of multi-color image on the printable surface of the glass. The digital press uses combinations of cyan, yellow and magenta inks or dyes to
    5 generate the second color image selected by the client.
    Next, the glass engraved with the first selected two or three-dimensional image and the second printed image is introduced into a firing oven to develop a firing stage in which the second previously printed image is permanently fixed to the printable surface of the crystal. Recorded.
    10 In order for the ink to be permanently fixed to the printable surface, a sufficiently high firing temperature, greater than 600ºC, is preferably applied in the range of 625 to 630ºC through the high-temperature oven, which supplies the heat directly to the second image printed on the printable surface of the internally etched glass.
    15 The temperature is around 625ºC, although it is selected based on the properties of the inks or dyes and the physical dimensions of the glass used such as the size and thickness or thickness, used to print the second image on the surface of the crystal.
    The temperature is applied for a time long enough to permanently fix the inks on the glass surface by heat. The cooking time is in the range of 6 to 20 10 hours, preferably 8 hours of temperature rise until the maximum cooking temperature is reached. Once cooking is complete, the clear material is allowed to cool naturally to room temperature, after which time the clear material is removed from the cooking oven. Therefore, the required temperature and cooking time are a function of the type of inks used and the physical dimensions of the
    25 transparent material.
    The second permanent image is sharp and its colors are intense.
    Glass engraved with a first image and imprinted a second image on a printable outer surface is a decorative item insertable into the designer stone headstone.
    The base material of the headstone is processed to make a suitable hole so that the engraved and printed transparent material is insertable inside the hole, which is made by means of a water jet cutting process.
    Now referring to figure 1, where the steps of the procedure of
    5 decoration of the transparent material and the addition of it to the hard material such as the headstone. The method comprises the selection step 11 of the crystal, which is laser engraved, recording step 12 of the first image; the etched glass is then fed into printing stage 13 by the digital printer that prints the second image on the outer surface of the glass. Once the
    10 printing stage, the engraved and printed glass is introduced into the high temperature oven, cooking stage 14.
    In hard material it is subjected to a waterjet cutting process 15, waterjet, so that in the assembly step 16, the cooled glass is inserted into the hole made in the hard material by waterjet cutting, providing the output of the
    15 assembly step 16 the headstone to which the laser etched and printed glass is attached.
