Description

  The present invention relates to a method for compensating for printing misalignment of a white portion corresponding to a design shape formed on a base layer and a hairline layer, respectively.

  In recent years, so-called hairline printing, in which an infinite number of streaks are provided on a metallic base layer, is often performed in order to give a high-class feeling to designs such as marks on vehicles, characters, symbols, and the like. 4 and 5 are diagrams for explaining a conventional hairline layer printing method and its problems, respectively, and FIGS. 4A and 5A correspond to cross-sectional views, and FIG. ) And FIG. 5B correspond to plan views.

  As shown in FIG. 4A, the surface of the flat fabric layer 1 made of a glass plate, a plastic plate or the like corresponds to a predetermined design shape, for example, the number “1” shown in FIG. 4B. The base layer 2 is printed with metallic ink while forming the whitened portion. On the upper surface of the base layer 2, a hairline layer 3 in which a white portion similar to the white portion of the base layer 2 is formed is printed.

Conventionally, the white portion of the hairline layer 3 has the same size as the white portion of the base layer 2 or is formed slightly larger as shown in Patent Document 1 below. In the present specification, the white portion means a transparent hollow portion formed to express a predetermined design.

  According to such a conventional printing method, as shown in FIG. 4A, printing displacement of the base layer 2 and the hairline layer 3, that is, printing of a white portion of the base layer 2 and a white portion of the hairline layer 3 is performed. When there is no deviation, as shown in FIG. 4B, the parting line 21 of the base layer 2 and the parting line 31 of the hairline layer 3 are evenly aligned, which is very attractive. However, as shown in FIG. 5A, when printing misalignment of the base layer 2 and the hairline layer 3, that is, printing misprinting of these white portions occurs, as shown in D of FIG. 5B. Moreover, the positional relationship between the parting line 21 and the parting line 31 becomes uneven, and a part of the base layer 2 is exposed greatly, so that the appearance is very deteriorated. In addition, the design is expressed with a blurred feeling. These appear to be more unpleasant due to imbalance with the high-quality feeling of hairline printing.

  Such a problem can be dealt with by using a high-precision printing apparatus or by printing with a small number of impositions, but this leads to an increase in cost.

  Therefore, in view of the above-described present situation, the present invention provides a method capable of compensating for printing misalignment of white portions corresponding to the design shapes respectively formed on the base layer and the hairline layer without incurring an increase in cost. Is an issue.

The printing misalignment compensation method according to claim 1, which has been made in order to solve the above-described problem, prints a base layer in which a first white portion corresponding to a design shape is formed on the surface of a flat fabric layer. Printing misalignment between the first white portion and the second white portion that occurs when printing a hairline layer in which a second white portion similar to the first white portion is formed from above the layer The second white portion is made smaller than the first white portion, and the hairline layer is printed so as to cover the hairline pattern and the entire periphery of the opening portion of the hairline pattern. It is characterized in that it includes an edge portion having a certain width .

  According to the first aspect of the present invention, the printing deviation within the range of the difference between the white portions is compensated only by making the second white portion of the hairline layer smaller than the first white portion of the base layer. be able to. For example, as shown in FIG. 2 (A), even if printing deviation of the base layer 2 and the hairline layer 3 occurs within this range, it is compensated as shown in FIG. There is nothing to do.

Furthermore, according to invention of Claim 1 , since the hairline layer contains the border part of the fixed width printed so that the inner periphery of a 2nd white part may be formed, the outline of a design shape becomes clearer. .

The printing misalignment compensation method according to claim 2, which has been made to solve the above problem, prints a hairline layer in which a second white portion corresponding to a design shape is formed on the back surface of a flat transparent fabric layer. Printing of the first white portion and the second white portion that occurs when the base layer on which the first white portion similar to the second white portion is formed is printed from above the hairline layer A method of compensating for the deviation, wherein the second white portion is made smaller than the first white portion, and the hairline layer is printed so as to cover the entire circumference of the opening portion by the hairline pattern and the hairline pattern. It is characterized by including an edge portion having a constant width .

According to the second aspect of the present invention, by making the fabric layer a transparent fabric layer, it is possible to obtain the printing misalignment compensation effect even when the hairline layer is printed on the back surface of the fabric layer.

  According to the first aspect of the present invention, the printing deviation within the range of the difference between the white portions is compensated only by making the second white portion of the hairline layer smaller than the first white portion of the base layer. be able to. For example, as shown in FIG. 2 (A), even if printing deviation of the base layer 2 and the hairline layer 3 occurs within this range, it is compensated as shown in FIG. There is nothing to do. Therefore, it is possible to compensate for the printing misalignment of the white portions corresponding to the design shapes respectively formed on the base layer and the hairline layer without increasing the cost.

Furthermore, according to invention of Claim 1 , since the hairline layer contains the border part of the fixed width printed so that the inner periphery of a 2nd white part may be formed, the outline of a design shape becomes clearer An effect is also added.

According to the second aspect of the present invention, by making the fabric layer a transparent fabric layer, it is possible to obtain the printing misalignment compensation effect even when the hairline layer is printed on the back surface of the fabric layer. Therefore, the application range can be expanded. Further, the hairline layer can be protected by the transparent fabric layer.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 are diagrams for explaining a first embodiment of a printing misalignment compensation method according to the present invention. FIG. 1 shows a case where there is no printing misalignment, and FIG. 2 shows a case where a printing misalignment occurs. FIG. 1A and FIG. 2A correspond to cross-sectional views, FIG. 1B and FIG. 2B correspond to plan views, and FIG. 1C corresponds to a perspective view. Yes.

  As shown in FIGS. 1 (A) and 1 (C), a predetermined design shape, for example, a number shown in FIG. The base layer 2 is printed with metallic ink while forming a white portion corresponding to “1” (referred to as a first white portion).

  From above the base layer 2, hairline layers 3 and 4 are printed in which a white portion similar to the first white portion (referred to as a second white portion) is formed. Here, the second white portions of the hairline layers 3 and 4 are formed to be smaller than the first white portion of the base layer 2. That is, when there is no printing misalignment, the parting line 41 of the hairline layers 3 and 4 is inside the parting line 21 of the base layer 2 as shown in FIG.

  The hairline layer 4 is also an edge portion having a constant width W that forms the inner periphery of the second white portion. This border portion (hairline layer 4) is formed in the same process as the hairline layer 3 so as to cover the entire circumference of the opening portion by the hairline layer 3 indicated by the dotted arrow 31. Both the hairline layer 3 and the hairline layer 4 are formed by applying an equivalent hairline printing to an equivalent metal base layer.

  As shown in FIG. 2A, it is assumed that printing misalignment between the base layer 2 and the hairline layer 3, that is, printing misalignment between the first white portion and the second white portion occurs. For example, it is assumed that the hairline layers 3 and 4 are printed shifted to the right in the drawing so that the parting line 41 overlaps the parting line 21. However, despite such printing misalignment, the base layer 2 is not exposed as shown in FIG. That is, the printing deviation is compensated. This is because the second white portion is formed smaller than the first white portion.

  As shown in FIG. 1A, a range from a state where there is no printing deviation to a state where printing deviation occurs as shown in FIG. 2B (the difference between the parting line 21 and the parting line 41 in FIG. 1A). ) Is completely compensated for printing misalignment. Therefore, even if a printing deviation within the above range occurs, the appearance is not affected at all. Even if a print misalignment occurs further to the right in the drawing as shown in FIG. 2B, the exposed area of the base layer 2 can be made smaller than before. Therefore, even if a printing deviation outside the above range occurs, the appearance is improved as compared with the conventional case.

  Since the printing method for compensating for such a printing misalignment can use existing devices and printing methods as they are, it is not necessary to use a high-precision printing device or reduce the number of impositions. Therefore, according to the first embodiment, the cost is not increased. Further, since the hairline layer 4 as the border is subjected to hairline printing equivalent to the hairline layer 3, no new printing material is required. Therefore, according to the first embodiment, there is no increase in cost due to printing of the border portion.

  FIG. 3 is a diagram for explaining a printing misalignment compensation method according to the second embodiment of the present invention. FIG. 3 corresponds to a cross-sectional view similar to FIG. In the second embodiment, as shown in FIG. 3, a transparent fabric layer 1 ′ is used instead of the fabric layer 1 of the first embodiment. And hairline layer 3 ', 4' and base layer 2 'are printed in order on the back surface of this transparent fabric layer 1'. As described above, by using the transparent fabric layer 1 ′, the same printing misalignment compensation effect as that in the first embodiment can be obtained when the hairline layer is printed on the back surface of the fabric layer. Therefore, according to the second embodiment, an effect that the application range of the present compensation method can be expanded is also added.

  As described above, according to the embodiment of the present invention, it is possible to compensate for the printing misalignment of the white portions only by making the white portions of the hairline layer smaller than the white portions of the base layer. Therefore, even if some printing misalignment occurs, the design can be clearly expressed without deteriorating the appearance. As a result, the cost is not increased.

  In order to make the hairline layer look more metallic, the base layer is often lighter than the hairline layer. For this reason, by making the hairline layer 4 as an edge part into a metal ground layer equivalent to the hairline layer 3 other than this, an appropriate contrast is generated and the design can be expressed more clearly.

FIG. 1A, FIG. 1B, and FIG. 1C are diagrams for explaining a printing misalignment compensation method according to the first embodiment of the present invention. 2A and 2B are diagrams for explaining the effect of the printing misalignment compensation method according to the first embodiment of the present invention. It is a figure for demonstrating the printing misalignment compensation method of 2nd Embodiment of this invention. FIG. 4A and FIG. 4B are diagrams for explaining a conventional hairline layer printing method. FIG. 5A and FIG. 5B are diagrams for explaining problems caused by a conventional hairline layer printing method.
