Description

  The present invention relates to a method for manufacturing a printed material whose printed surface looks like leather or stamped leather, an apparatus for manufacturing the printed material, and the printed material.

Conventionally, in the field of printed matter, there are various printing methods for applying a special design to the printed matter. One of them is a raised printing method that makes printed characters and patterns appear to be raised. As such a raised printing method, a method generally called barco printing is known.
Barco printing is a method of sprinkling resin powder made of thermoplastic resin or heat-foamable resin on the surface of printed matter on which characters or designs have been printed or varnished on top of the printed matter. This is a printing method in which a desired character or design appears to be raised by removing the resin powder in the portion and then heating and cooling it.

  For example, in Patent Document 1, lamé powder is mixed with resin powder and sprinkled on the surface of the printed matter, so that the lamé powder is fixed in a partially embedded state on the raised portion, thereby increasing its brightness, and lamé powder. A raised printing method is disclosed that is difficult to fall off from printed matter.

  In Patent Document 2, ink droplets are ejected onto a base material to form an ink image, and resin powder is deposited on the base material while the ink image is undried, thereby allowing various fixed information to be little by little. A raised printing method for raising is disclosed.

  In addition, although not a printing method, as a method of performing special processing on paper, for example, a method of manufacturing pseudo-leather paper in which Japanese paper is bonded with a plurality of sheets and the surface thereof is subjected to painting processing and mold finishing is cited. This relates to a paper manufacturing method for making paper itself look like leather.

  In the subsequent cooling process (step S510) by the cooling unit 450, the resin layer 530 is cooled and fixed to the print layer 520 by cooling the heated substrate 510. Examples of such a cooling method include a method in which the heated substrate 510 is allowed to stand at room temperature for a certain period of time, in addition to a method in which the surface of the substrate 510 is cooled by applying air from a fan.

The printed matter 500 manufactured through such processes has the following configuration depending on the combination of colors of the base material 510, the ink, and the resin powder.
That is,
(A) The printing layer 520 and the resin layer 530 are transparent, and the substrate 510 is colored (including black and white).
(B) The resin layer 530 is transparent, and the substrate 510 and the print layer 520 are colored (including black and white). Or
(C) The printing layer 520 is transparent, and the substrate 510 and the resin layer 530 are colored (including black and white).

  In the cases (b) and (c), the base material 510 and the printed layer 520 or the base material 510 and the resin layer 530 may be the same color or different colors.

  When the printed layer 520 and the resin layer 530 are transparent and the substrate 510 is colored (including black and white), the brightness of the multilayer portion of the substrate 510, the printed layer 520, and the resin layer 530 is the substrate. It is preferably lower than the lightness of 510. With such a configuration, in particular, when the pattern of the printing layer 520 is a leather pattern, the printed matter 500 can be made to look more like leather because of its color and gloss.

  Furthermore, the thickness of the resin layer 530 is preferably 0.01 mm to 0.1 mm. A more preferable thickness of the resin layer 530 is 0.01 mm to 0.05 mm. By adopting such a configuration, it is possible to present a natural ridge like leather and to appear as if a pattern was printed with lacquer.

  In the coating process (step S512) by the coating unit 460, which is the final process, the coding layer 600 is formed with PP so as to have a thickness of about 0.02 mm uniformly with respect to the back surface that has become the printed matter 500 after the cooling process (step S510). Processing to form is performed. The PP coating method uses a mat type laminator, but is not limited thereto.

  As shown in FIG. 6, the printed material 500 subjected to the coating process manufactured according to the above embodiment includes a base material 510, a printed layer 520, a resin layer 530, and a coating layer 600. The print layer 520 is printed on the base material 510 so as to have a predetermined pattern, and the resin layer 530 is formed on the print layer 520. Such a printed matter 500 can be easily processed into, for example, a book cover, a notebook cover, a bookmark, a file, a business card holder, a tablet-type portable terminal device, a smartphone, or the like. Moreover, it can also utilize as a seal | sticker by bonding these printed matter 500 to an adhesive film, or printing on a sealing film. That is, according to the above-described embodiment, it is possible to provide an excellent effect that it is possible to provide a printed material 500 that is excellent in handleability and has a wide use range. In addition, the cost advantage can be ensured, and a practical and economical printed matter 500 can be provided.

  When this embodiment is explained in full detail, when using the offset printing machine as the printed material manufacturing apparatus 400, for example, a printed pattern 520 is formed by printing a leopard pattern with a transparent medium on a red high quality paper as the base material 510. When viewed from the printing surface, printing is performed so that the printing layer 520 becomes a pattern of the raised portion of the crust.

  Next, the high-quality paper (base material 510) on which the print layer 520 having the leopard pattern is formed is a resin powder cloth in which a transparent thermoplastic resin powder is spread within about 20 seconds after being discharged from the offset printing machine. It is carried into a container in the unit 420. And in this container, the said thermoplastic resin powder is sprinkled on quality paper. At this time, it is preferable to sprinkle so that the thermoplastic resin powder adheres to all of the printing layer 520.

  Thereafter, the thermoplastic resin powder other than the surface portion of the printed layer 520 is removed by suction using a suction device as the resin powder removing portion 430. The high-quality paper from which excess thermoplastic resin powder has been removed is transported to the belt conveyor of the first transport mechanism 434 and transported to the heating device serving as the heating unit 440. The belt conveyor may be connected as a single conveying device so as to pass through the suction device, the heating device, and the cooling device. In this case, the high-quality paper placed on the belt conveyor is continuously from the suction device to the cooling device. Will be transported.

  Further, the high quality paper passes below the heater unit 442 provided in the heating unit 440 by a belt conveyor. The temperature of the heater unit 442 is adjusted to about 200 ° C. to about 700 ° C., and the time for the high-quality paper to pass through the heater unit 442 is about 2 seconds to about 10 seconds. The high-quality paper that has passed through the heater section 442 is heated, and the thermoplastic resin powder adhering to the printing layer 520 is expanded and dissolved by this heat. The heated high quality paper is conveyed to a cooling device as a cooling unit 450 by a belt conveyor.

  The high quality paper passes through the blower 452 provided in the cooling unit 450 by the belt conveyor. The temperature of the wind sent from the blower 452 is preferably room temperature or lower. The high quality paper that has passed through the blower 452 is cooled, and the thermoplastic resin that has been expanded and dissolved by the heating unit 440 is fixed on the printing layer 520. As a result, a resin layer having a thickness of about 0.15 mm is fixed on the printing layer 520, and the printed matter 500 is completed.

The printed matter 500 manufactured as described above has the resin layer 530 of the raised portion of the crust because of the unevenness and gloss of the resin layer 530 and the color of the multi-layer portion of the fine paper, the print layer 520 and the resin layer 530. Thus, the printed surface looks as if it is a red-colored crusted product.
Thus, the coating layer 460 is applied to the back surface of the printed matter 500 to form the coding layer 600 with PP so as to have a uniform thickness of about 0.02 mm.

  Similarly to the above, it is also possible to print a cloisonne pattern on black high-quality paper with black ink. In this case, the printed matter produced has a high-quality paper, printed layer, and resin layer in which the lightness of the multi-layer part is higher than that of the high-quality paper, and because of the unevenness and gloss of the resin layer, the resin layer is made of Japanese lacquer. It looks like a pattern, and its printed surface looks like a seal stamped with black lacquer.

According to the above-described embodiment, the colors of the base material 510, the print layer 520, and the resin layer 530 made of paper are set to a specific combination by using raised printing without using special paper or base material. Thus, it has become possible to easily produce a printed material having a printed surface that looks like leather or a seal. In addition, it is possible to reduce time and labor for manufacturing raw materials and manufacturing, and it is possible to secure cost advantages and achieve economic effects. In addition, according to the above-described embodiment, it is possible to provide an excellent effect that it is possible to provide a printed material with excellent handling properties and a wide use range.
In addition, the coating of the thermoplastic resin increases the strength, water resistance, and water repellency of the printed material 500 and makes it difficult to get dirty, and also has a practical and excellent effect of being excellent in durability.
Furthermore, the coating may be performed not only on the back surface of the printed matter but also on the surface side on which the printed layer is formed.

  Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
