Definitions
- the present invention relates to a method of manufacturing reliefs formed by recesses, cavities or recesses on a substrate, for example, in the form of engravings or textures.
- the invention relates to a machine for manufacturing such reliefs, as well as to a panel with such reliefs.
- the invention is related to the industry dedicated to the manufacture and decoration of panels and, more specifically, panels for floors, walls, furniture, etc.
- Embossing is obtained by digitally printing a digitized representation of the relief with a drop-shaped liquid printing product that is deposited or injected onto a relief base layer that is spread over the substrate.
- digital printing allows to obtain reliefs with a much higher definition, precision or sharpness compared to conventional methods of manufacturing reliefs formed by recesses on a substrate such as, for example, stamping or molding.
- Various printing techniques are known for digital printing of reliefs formed by recesses on a substrate.
- the present invention applies to any digital printing technique based on depositing or injecting a recess printing product, liquid in the form of drops, on the relief base layer.
- the recess printing product enables a recess to be produced in the relief base layer by being deposited or injected thereon. As the volume per area of recess printing product increases, the depth of the recess to be formed with respect to the outer surface of the relief base layer increases.
- an undercut printing product is mixed with the relief base layer.
- the recess is obtained after removing the mixture between the printing product and the relief base layer, so that the recess corresponds to the volume of the mixture removed.
- Said mixture can be removed by mechanical means, such as brushing.
- a known variant of this printing technique is based on using a UV curable resin relief base layer. After the relief base layer is spread on the substrate, the liquid printing product is digitally printed on the uncured or partially cured liquid relief base layer. The relief base coat is cured together with the mixed printing product.
- This printing product can be configured so that after curing of the relief base layer together with the printing product the removal of the cured mixture from the cured base layer is facilitated, for example by mechanical means such as brushing. For this, it is possible to use, for example, an inkjet ink under the brand "trueTexture" of the Italian manufacturer ZEETREE, SRL.
- Another known variant of this printing technique is based on using a solvent printing product in or chemically reacting with the relief base layer.
- This technique is widely known in the field of manufacturing electronic components, making it possible to produce recesses of reduced size, more suitable for microelectronics applications, as described, for example, in EP 1327259 B1.
- a second widely known digital printing technique of the type to which the present invention is applied is based on the simple deposition or injection of the recess printing product on a liquid relief base layer, so that the relief is produced by displacement of the material. of the relief base layer caused by the impact of the drops of the printing product on the relief base layer.
- This digital embossing technique is called digital embossing.
- Obtaining the recesses takes place after solidification of the relief base layer, for example by curing.
- the printing product can be removed, for example, by evaporation.
- it is possible to obtain reliefs formed by recesses of different depths. This technique is described, for example, in patent document EP 3109056 A1.
- the recess obtained substantially corresponds to the material removed from the mixture between the printing product and the relief base layer,
- the recess is not produced by the simple deposition or injection of the printing drops on the relief base layer and their subsequent solidification, but to produce the recess it is required to remove a mixture between the printing product and the relief base layer.
- This second digital stamping printing technique has the drawbacks that it only allows to generate recess areas of the relief base layer that are narrow, shallower and of much less definition, compared to the first printing technique, printing technique for the that there is no limit to the width of the recess.
- the present invention aims to provide a process for manufacturing reliefs formed by recesses with improved definition, precision or sharpness for recess widths of any size and of improved quality in terms of surface finish, avoiding sharp or scratchy edges to the touch.
- the present invention provides a method of manufacturing a relief formed by recesses on a substrate.
- the relief comprises a recess area and a non-recess area.
- the recess area is adjacent to the non-recess area and forms a recess with respect to the non-recess area.
- the relief may comprise a plurality of recess areas and non-recess areas.
- the process comprises the following steps: spreading a relief base layer on the substrate, digitally printing with a first volume per area of liquid recess printing product in the form of drops on the outer surface of the extended relief base layer to obtain the recess area, the area of recess forming the recess with respect to the outer surface of the extended relief base layer, digitally printing with a second volume per area of droplet liquid undercut printing product on the outer surface of the extended relief base layer, at least adjacent to the undercut area, to obtain the non-undercut area.
- relief can be understood, for example, as an engraving or a texture.
- recess it is understood, for example, a recess or a cavity.
- the recess may have a variable recess depth, relative to the outer surface of the extended relief base layer.
- recess area is meant the surface formed by the recess in the relief base layer obtained by digital printing with the first volume per area of recess printing product on the outer surface of the extended relief base layer.
- non-recess area is meant the surface obtained by digital printing with the second volume per area of recess print product on the outer surface of the relief base layer adjacent to the corresponding recess area.
- the non-recess area extends at least partially between recess areas and / or an edge of the relief base layer, in particular, at least 10%, preferably at least 50%, more preferably totally.
- the surface of the non-recess area obtained can be substantially smooth relative to the recess of the adjacent recess area.
- substantially smooth surface of the non-recess area it is also possible to understand a matt surface and / or with a substantially reduced surface roughness with respect to a maximum recess depth of the recess in the recess area, that is to say, in particular, a lower surface roughness or equal to 10% of said maximum recess depth, preferably 5%, even more preferably 1%.
- the recess printing product is mixed with the relief base layer to form the recess area.
- the method comprises removing a mixture of printing product and relief base layer, so that the recess in the recess area corresponds to the volume occupied by the removed mixture in the relief base layer.
- the removal of the mixture can be carried out, for example, by mechanical means, such as brushing, suction, blowing, blasting with pressure material (water, sand or any other abrasive element), by evaporative means, for example, with hot air or IR radiation or by chemical means.
- the recess printing product is deposited or injected onto the liquid relief base layer by means of the digital stamping printing technique, that is, by digital stamping.
- the volume per area of printing product in particular the droplet volume, and / or the droplet ejection speed, can be varied.
- the digital printing according to the invention is carried out on the liquid relief base layer.
- the relief base layer solidifies, sets and / or cures during and / or after digital printing (with the first volume per area and / or with the second volume per area printing product).
- the relief base layer can be solidified, fixed and / or cured, for example by heat, electromagnetic radiation and / or light, in particular by UV, IR.
- the relief base layer is cured, especially by UV.
- the liquid relief base layer may be uncured or partially cured during digital printing, in particular also with the first volume per area and / or with the second volume per area of the printing product.
- curing includes the concept of polymerization.
- resin resins can be used for the curing liquid relief base coat.
- cured such as radical, acrylic, polyurethane resins, as well as mixtures of these. Curing monomers or oligomers, as well as mixtures of these, can be used as undercut impression products that can be mixed with the liquid base layer.
- the printing product for the first volume per area may be of the same or different material as the printing product for the second volume per area. It is also contemplated that it can be printed with different printing product materials for different spots on the relief base layer.
- Said printing product can be configured so that after curing of the relief base layer together with the printing product the removal of the cured mixture from the cured base layer to form the relief, in particular the recess area, is facilitated.
- the printing product can be configured to provide incomplete or inhibited cure of the mixture between the printing product and the base layer.
- the relief base layer may be solid, in particular porous, to facilitate mixing of the printing product with the relief base layer.
- a solvent for the relief base layer can be used as the printing product.
- Digital printing with the second volume per area of print product can be performed simultaneously, before or after digital printing with the first volume per area. It is preferably carried out simultaneously, more preferably before, so that the confinement of the drops of the first volume of printing product by means of the drops of the second volume of printing product can thus be promoted. It is considered that the order of magnitude of the injection and advance times of digital printing is much lower than that of the dispersion or penetration times of the drops of printing product in the relief base layer, especially for the digital printing of a single pass, so equally effective results can be achieved regardless of when the first volume and second volume are printed. In this regard, however, more preferably said fingerprints can be made immediately consecutively.
- the digital printing with the second volume per area is also performed on the extended relief base layer on which the digital printing with the first volume per area is made, that is, not only on a non-recessed area of the surface exterior of said extended relief base layer.
- the digital printing with the second volume per area is also performed on the extended relief base layer on which the digital printing with the first volume per area is made, that is, not only on a non-recessed area of the surface exterior of said extended relief base layer.
- a second volume per area is preferably greater than or equal to 5% of a first volume per maximum area in the recess area, more preferably 30%, even more preferably 50%. Also, a second volume per area is preferably less than or equal to said first volume per maximum area, more preferably 70%, even more preferably 50% of said first volume per maximum area.
- a drop volume for the second volume per area is less than or equal to 70% of a maximum drop volume for the first volume per area, more preferably less than or equal to 50%, even more preferably, 30%.
- the volume of recording product in the adjacent non-recess area is thereby decreased, without detriment to the effect of confining the drops of the first volume of recording product in the recess area.
- the second volume per area and, optionally, the drop volume for said second volume per area is uniform throughout the relief base layer, that is, for the area of no undercut and / or for the stope area. In this way, a uniform finish is achieved in the non-recess area. It is also contemplated that the first volume per area is uniform throughout the relief base layer, corresponding to a constant depth of the recess area.
- the second volume per area and optionally the drop volume for said second volume per area is such which produces a surface roughness of the relief base layer in the non-recess area less than or equal to 20 microns, more preferably 10 microns, even more preferably 5 microns, and / or, preferably, is such that it produces a 60 ° gloss greater than or equal to 10 GU, more preferably 20 GU, even more preferably 50 GU.
- surface roughness and gloss at 60 ° are considered, in particular, measured immediately after removing the mixture.
- the embossing is done in registration with an image printed on the substrate, visible through the embossing base layer.
- the relief base layer can be transparent or translucent.
- the spreading of the relief base layer on the substrate can be carried out, for example, by roller, in particular by reverse roller, in a conventional manner per se.

Thus, it is possible to provide recesses with a corresponding depth.
- the relief base layer spread over the substrate has a thickness greater than or equal to 20 microns, more preferably 30 microns, even more preferably 50 microns and / or, preferably, less than or equal to 300 microns, more preferably, 200 microns, even more preferably, 100 microns.
- the invention it is possible to obtain reliefs with a depth of up to 100-300 microns, for the recess area. Also, the greater recess depths that can be obtained make it possible to achieve the effect of achieving a better definition of the corresponding recess areas with surface roughnesses of the non-recess area of, for example, from 1-5 microns to 10-20 microns.
- the method comprises digitizing a relief representation, which defines the recess area and the non-recess area, the recess area, for example, with a recess depth value, associated with the depth of the recess area (ie, relative to the outer surface of the raised base layer once spread over that which is digitally printed to form the recess area), per point of the relief representation.
- a volume per area of variable printing product per point of the relief representation to obtain, for example, a recess with a variable depth in the recess area.
- the term point of the relief representation comprises the concept of pixel.

- a design effect can be provided in which the relief (20) and the image are associated or linked to each other, for example, being able to overlap or coincide seen from the upper part of the substrate (3).
- the image can comprise a motif, a color, a shape, etc.
- a printed image can be produced on the relief (20), in particular, synchronously, that is, in registration between the image and the relief (20).
- first volume per area (41) of printing product and the second volume per area (42) of printing product this can be varied depending on, for example, the level, volume or size of the injection droplet, the number of jet points per printer area or resolution (for example, measured in dpi, that is, dots per inch).
- a parameter can be defined associated with the volume per area of printing product that can be injected onto the relief base layer (2), setting a digital printing procedure and / or a digital printer (12) to obtain reliefs. (twenty).
- the volume per area of maximum printing product obtainable by means of a certain procedure and / or digital printer (12) is assigned a value of 100%.
- a contribution percentage of 0% indicates that no printing product is applied. The higher the fill percentage or volume per area of print product, the greater the depth of recess that can be achieved.
- the percentage of contribution corresponding to the second volume per area (42) of printing product is relatively low compared to the percentage of contribution corresponding to the first volume per area (41) of printing product.
- the non-recess area (22) is not substantially recessed, perforated or worn while providing a recess area (21) with an improved definition and, therefore, very high quality reliefs (20). .
- FIG 2 it shows a substrate (3) in the form of a panel (1).
- a relief (20) formed by recesses in a relief base layer (2) is applied.
- the relief (20) is formed by recess areas (21) and non-recess areas (22).
- the figure shows the substrate (3) with the mixture (40) of the material of the relief base layer (2) and printing product in the relief base layer (2), prior to removing the mixture (40) to obtain the recesses corresponding to the volume occupied by the mixture (40).
- both first volume drops per area (41) of printing product (for the recess areas (21)) and drops second volume per print area (42) (for non-recess areas (22)).
- the digital printing of the printing product was carried out with a digital printer (12) of a single pass (“single pass”) with two print heads, with a resolution of 360 dpi and 3 drop levels (volume of the injected drop) : 14 pl, 28 pl and 43 pl.
- an injection ink was used under the trademark "trueTexture” from the Italian manufacturer ZEETREE, SRL.
- the volume of print product per area can be varied, for example, by selecting the number of digital printer nozzles (12) per area, the drop level per nozzle, as well as the number of passes or number of print heads per printers. digital (12) in a single pass to deposit the printing product on the relief base layer (2).
- a pass was made with said digital printer (12).
- the printing was carried out at a speed of 25 m / min on a substrate (3) of the SPC type (“stone plastic composite”) of dimensions 1000x200x4 mm (usual dimensions of slats for floors).
- the maximum volume per area of print product for the exemplary embodiment corresponds to an injection with a maximum resolution of 360 dpi x 360 dpi and a maximum droplet level of 43 pl in 1 pass with the 2 print heads, that is, a volume per area of print product of 17,276 ml / m2. This volume per area of maximum printing product corresponds to the percentage of contribution of 100%.
- the percentage of contribution of printing product for digital printing varies between 0% and 100%, such that the higher the percentage of contribution, the greater the depth of its penetration within the relief base layer (2) in the that the printing product is injected and therefore the depth of the recess obtained.
- a UV curing resin was used, which can be obtained from the manufacturer KLUMPP, under the reference 161-000-00430 ("UV Sealer").
- the resin was spread on the substrate (3) by roller, with a thickness of relief base layer (2) of approximately 100 microns, corresponding to a grammage of approximately 100 gr / m2.
- the relief base layer (2) was printed uniformly with a first volume per area (41) of constant printing product, corresponding to the contribution percentage of 100 %.
- the relief base layer (2) was printed uniformly with a second volume per area (42) of constant printing product, less than the first volume per area (41) of printing product .
- the second volume per area (42) of printing product was extended along the entire relief base layer (2) for the non-recess area (22).
- the relief representation (30) of Figure 4 corresponding to a fine line texture (I), increasing the width of the texture lines gradually to obtain a relief representation (30) corresponding to a medium line texture (ll) and a thick line texture (III).
- processed relief representations of Figure 5 were generated. These processed relief representations are images that define the percentage of contribution of the printing product by means of a gray scale between white, which corresponds to a 0% contribution, and black, which corresponds to a 100% contribution.
- the processed relief representations are shown in figure 5 arranged in a matrix where the rows correspond to the contribution percentage corresponding to the second volume per area (42) of printing product, for 0%, where nothing is printed in the areas of no undercut (22) (adjacent to undercut areas), 5%, 15%, 30% and 50%.
- the columns of the matrix correspond to the width of the recess areas, in the example of the lines that form the relief (20), that is, a thin (I), medium (II) and thick (III) width.
- the processed relief representations are processed by a computer program (17) of the computer system (16) for the digital printer (12) to determine the injection, the volume per area of printing product, the number of drops per area, the level gout, etc.
- the samples with the printing product deposited or injected on the relief base layer (2) were cured by means of UV lamps applying a total energy of 200mJ / cm2, with a wavelength of between 230-410 nm and a power peak. 600 mW / cm2 initiation of the curing reaction.
- the mixture (40) between the printing product and the relief base layer (2) was removed by brushing, thus obtaining the reliefs (20) or textures formed by recesses, corresponding to the recess areas.
- Figure 6 shows some photographs of the samples made, corresponding to the processed relief representations of figure 5.
- a better definition of the relief (20) is obtained, as well as a transition between the recess area (21) and the area of non-recess (22) smooth or progressive, which results in a higher quality of the relief (20) or texture.
- a relief (20) with a contribution of 50% and a fine line (I) is very defined and visible compared to a relief (20) for a contribution of 0% and a fine line (I) where there is hardly any appreciate the relief (20).
- a relief (20) with a contribution of 50% and a thick line (III) is much more defined and not rough to the touch, unlike relief (20) for a contribution of 0% with a thick line (III ).
- Figures 7 to 10 show some photographs in which the reliefs (20) with contrast can be seen in detail, already without the black pigment of Figure 6.
- Figure 7 shows the relief (20) for a contribution of the 0% and fine line (I).
- Figure 8 shows the relief (20) for a contribution of 0% and a thick line (III).
- Figure 9 shows the relief (20) for a contribution of 50% and a fine line (I).
