Detailed description of the invention
The présent invention relates to a system and a two-dimensional (2D) printing method in a three-dimensional (3D) printing support, which consists of forming a printing support made of a plurality of colored fibers that follow a printing pattern, which once joined and shaped into a block can be transversally eut, thereby obtaining printed sheets according to said printing pattern.
In a first embodiment of the invention, according to what is illustrated in figures 1 and 2, said printing support is formed of a block (1) which comprises a plurality of hollow tubes (2), wherein each hollow tube (2) has a cavity (3), which is filled with a coloring medium (6), such as ink or the like, preferably of the paste type, which flows into said cavity (3) so that when the coloring medium gets dry, the block (1) becomes solid. Each cavity acts as a support for the coloring medium. The filling with the coloring medium (6) into each of the hollow tubes (2) follows a printing pattern, previously established for the front face (4) of the block (D- vX
After the coloring medium becomes hard and the block (1) is solidified, it can be transversally eut parallel to the printing face (4) in a plurality of strips (5) that will dépend on the required volume of posters, placards or adevertising banners, among others.
The hollow tubes (2) are filled with the coloring medium (6), the color of which can vary for each cavity (3). As illustrated in figure 3, first cavities (3) are filled with one color (C1 ), second cavities (3) are filled with one color (C2), third cavities (3) are filled with one color (C3), and fourth cavities (3) are filled with one color (C4). This filling with different colors into the different cavities (3) of the front printing face (4) of the block (1) continues until said colors conform the predefined pattern for said front printing face (4). Each cavity (3) can be homologated to a printing “pixel, which could follow the same printing pattern of a conventional printer. The color of the coloring medium (6) can vary for each cavity (3) filled so as to generate a printing pattern, or otherwise, it can be maintained in a group of cavities (3) to generate a bigger pixel.
This is based on traditional offset, serigraphy or digital printing, wherein cyan, magenta, yellow and black (CMYK), also called four color print, combine their pigmentation to generate ail the desired colors. On observing a printing with a magnifying glass or a threadeounter, only four colors will be seen in the support, but looking from a farther distance they become fused at sight and hundreds of colors will appear.
Some serigraphs even have a big enough grain, wherein it is possible to observe at a glance the CMYK sets of dots of approximately 1 mm each.
In the case of the présent invention, a traditional chromatics like CMYK can be obtained by filling the cavities (3) with different proportions and locations, generatîng, as a resuit, many colors seen from a distance, similar to conventional printing.
In one of the embodiments of the présent invention, the strips (5) can have a large size, such as for example, gigantographs, wherein the coloring medium (6) utilized in the block (1) has the colors (C1, C2, C3, C4), which can be associated with the basic colors in different color densifies by number of cells, thereby, with said densifies it is obtained the desired color of a pixel of the printing pattern.
In another embodiment of the invention, the hollow tubes (2) hâve inside the cavity (3) an absorbent medium (7), such that said coloring medium (6), when being in liquid form, flows through said absorbent medium (7) through ail the interior of the hollow tube (2), by the effect of capillarity or absorption, The hollow tubes (2) can be filled with fiber, sponge or the like.
In another embodiment of the invention, the hollow tubes can be replaced by solid tubes (8), the cross section of which (7r) is already colored with some of the colors (C1, C2, C3, C4) which are previously selected according to the printing pattern and grouped according to said pattern. Said cross section (7’) is équivalent to a support for the coloring medium (6) that bears the colors (C1, C2, C3, C4).
The hollow tubes (2), as well as the solid tubes (8), hereinafter generically termed as tubes (2, 8), can hâve varîed shapes and arrangements.
In figure 6, the block (1) is formed of tubes (2, 8) having a circular section. The lines that form the block (1) are overlapped with respect to each other, reducing the interstice generated between circle and circle, as shown in figures 1 to 5. In figure 7, the block (1) is formed of tubes (2, 8), the section of which is square, one tube being disposed over the other, generating a layout of aligned columns and rows. In figure 8, the block (1) is formed of tubes (2, 8) the section of which is triangular. In figure 9, the block (1) is formed of tubes (2, 8) the section of which is an hexagon , forming a front print face (4) in the shape of a honeycomb. In figure 10, the block (1) is formed of two types of tubes (2, 8), wherein a first male tube (8) has a preferably square section, having on each side of said square, male engaging means (10); and wherein a second female tube (9) has a preferably square section, having on each side of said square, female engaging means (11). In this case, on the four faces of each male tube (8) are mounted four female tubes (9), utilizing for that purpose the male means (10) and the female means (11 ) of each tube (8, 9). In figure 11, the block (1 ) is formed by a single type of tube (2, 8), wherein said tube is a male-female tube (12) having a preferably square section, having on two adjacent sides or on two opposite sides, male engaging means (10); and on the two corresponding adjacent contrary sides or on the corresponding opposite contrary sides, having female engaging means (11). In this case, the male-female tubes (12) are mounted one over the other and one next to the other.
For the case of the hollow tubes (2), they can be formed in a single block (1), ready to be filled with the coloring medium (6). In figure 12 are illustrated four examples of a column of tubular means, wherein each hollow tube is joined one over the other, forming a single assembly, and in figure 13 is illustrated the complété block (1), formed by the first example shown in figure 12.
Due to the foregoing, the 3D printing means can be prefabricated and previously joined before being filled with the coloring medium (6).
The preferred materials can be polymers, cellulose or the like.
In another embodiment of the invention, the hollow tubes (2) or the solid tubes (8) can be joined with adhesive, thermal fusing or ultra frequency , among other Systems known in the art.
Referring to figures 14, 15 and 16, the block (1) of the présent invention can be formed in a linear manner placing the tubes (2, 8) one beside the other, juxtaposed. A printing pattern (13) is configured in said tubes (2, 8), which when being rolled, following a rolling pattern (15) display the printing pattern (13) on the face (4) of the block. Said rolling pattern can be hexagonal, as shown in figure 15, or in zigzag, or other one adapted to the printing pattern to be displayed.
In another embodiment the block can be formed of a stack of paper, which can be of cellulose or polymer origin, as shown in figures 18 to 20. Each paper (17) has a structure formed by a plurality of absorbent zones (18) which are delimited by non absorbent spans (19). A plurality of these paper sheets (17) is stacked and is joined, for example by a casing (20) to form the block of the présent invention, thereby leaving a front printing face (4). In this case, the coloring medium (6), which can be ink in this case, is disposed in the absorbent zones (18), which, by capillarity, are distributed toward the paper sheets (17) located at the interior of the block. The coloring medium does not get mixed with another one, because each absorbent zone (18) is delimited by non absorbent spans (19), thus allowing to generate the printing pattern toward the interior of the block (1 ). v/
I
In another embodiment of the présent invention, it is possible to form placards with silhouettes of objects or persons, in a real size scale, for placing them at sales points, for example. In this embodiment, shown in figure 17, the contour of the desired silhouette printing in the block (1), the outside spaces (16) of the printing pattern (13) are filled with a substance that weakens the material of the block, so that once the desired zone gets hard, the rest is mechanically removed, it cornes off from the hard block, leaving a printing block with the shape of silhouettes of objects or persons in a real size scale, which in figure 17 is represented by an arrow to the right. If the block (1 ) has been formed with plastic material for example, the substance can be a diluent that weakens the walls of the hollow tubes (2) of the outside (16) so that it is easy to pull it off from the shallow tubes (2) that contain the coloring medium for forming the printing pattern (13).
In figures 26 to 31 it is shown a practical formation of the silhouette of a person.
In a block (1) a printing pattern with the shape of the silhouette of a person (13) is formed in the front face (4), wherein the outside spaces (16) of said silhouette of a person (13) hâve been filled with a substance that weakens the material of the block (1). This block (1) is eut into a plurality of placards (14) and the outside space (16) îs easily eliminated by the content of the weakening substance, so as to form a person’s silhouette (13) in normal size. This silhouette can be generated of appropriate thickness so that it can be self standing, or it is possible to maintain it standing, by means positioned at the rear part of the real size silhouette. In another embodiment, the block (1) can be formed by a first silhouette of a person in normal position (13a) and the same person in inverted position (13b), wherein the outside spaces (16) of said silhouettes (13a, 13b) hâve been filled with a substance that weakens the material of the block. Once this block (1) is eut and the outside is removed, both silhouettes (13a, 13b) are folded into an inverted “V to form a real size self supporting placard.
Referring to figure 22, in the front face (4) of the printing block (1), the cavities (3) of the hollow tubes (2) are filled with the colors of the coloring medium (6), or otherwise, the solid tubes (8) are distributed according to the color thereof to form the block (1), wherein the fillings of the cavities (3) with the coloring medium (6) or the distribution per color of the solid tubes (8) follows a printing pattern (13), shown in the example by a face “©”.
Once the block (1) has been formed and printed with the printing pattern (13), it is transversally eut, parallel to the front print face (4), in a plurality of strips (5), for making posters, placards or advertising banners, among others, according to what is shown in figure 23.
As illustrated in figures 24 and 25 , the block (1) can be eut into strips of more thickness, to make up panels (14) having always the same printing pattern (13) printed on their faces.
These panels (14) are useful for constructing, for example, a display stand or a stand for advertising events, since as they corne from the same block and hâve the same measures, said panels (14) hâve a modularity effect that has not been achieved up to now in the state of the art. An example of this embodiment of the invention is illustrated in figure 32.
The block (1 ) of the présent invention can also be formed by extrusion, as shown in figure 21. For this purpose, a coloring medium of the paste type, such as for example ink, paint, soft polymer of predetermined colors according to the printing pattern (13), through a plurality of nozzies (22) located in a head (21), wherein said nozzies (22) hâve a distribution of the front face (4) type. Each nozzie generates a tube (2, 8) of coloring paste, so that when it cornes out, for example, by gravity, said tubes (2, 8) are generated separately and then they melt down and they get dry together, generating a block (1) already colored. In this alternative the block is generated when the tubes (2,8) corne out of the nozzies, which allows to generate a block (1) of a required length, thereby saving on storage and transportation of the blocks, furthermore diminishing the loss associated with remainders of the material that forms said block.
When the block (1) has been formed by extrusion, as shown in figure 21, the printing pattern with the shape of the silhouette of a person (13) is the one that is ejected by the head (21) through the nozzies (22) programmed to that effect. The rest of the nozzies, that would represent the outside spaces (16) of said silhouette (13), would be blocked.
