Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for obtaining a composition suitable for each printing or processing from a design required by a designer when printing or deforming a three-dimensional object.

[0001]

BACKGROUND OF THE INVENTION A printing method for printing on three-dimensional objects such as pad printing, shape processing of a printed sheet, insert molding of a printed film, vacuum forming of a printed sheet, compression molding, plastic deformation of a printed thin metal. It can be used widely, for example, when the designer requires a design that matches the printing method or processing method of the three-dimensional object from the design requested by the designer.

[0002]

2. Description of the Related Art In the case of printing on a three-dimensional object or deforming the printed object, it is often necessary to create a composition from a design required by a designer, often based on the feeling and experience of a skilled worker. Efforts are made to repeatedly approach the design required by the designer through printing trials and correction of the composition, and in some cases, the composition is completed by the approach of the designer and the printing company. It took a long time from prototype to mass production to repeat revisions and negotiate with designers.

[0003]

SUMMARY OF THE INVENTION In the case where a design required by a designer is regularly distorted, a composition suitable for a printing method or a processing method of the three-dimensional object is obtained, and when the printing is performed on the three-dimensional object, the designer is required. Is intended to reduce the time required to start mass production by creating a composition that will be the design required by.

[0004]

Means for Solving the Problems Printing on a three-dimensional object using a test plate, and scanning or photographing both the test plate and the image printed on the three-dimensional object.
By knowing the displacement between the composition and the image, the characteristics of the displacement due to the printing method or processing method of the three-dimensional object can be grasped by intersection recognition or line recognition. Conversely, the design required by the designer can be obtained by the printing method of the three-dimensional object. A composition that is distorted according to the processing method is obtained on a screen by a computer. By constructing a method and an apparatus for creating a composition that enables the distorted composition to be output as CAD data or prints,
It is an object of the present invention to provide a method and an apparatus that enable creation of a printing plate that reproduces a design required by a designer when printed on a three-dimensional shape by the printing method or formed by the processing method.

[0005]

[Function] It is easy to shorten the time from trial production to mass production by reducing composition correction and negotiation with designers.

[0006]

[Example] As a test print

[Fig. 1] Under a composition with grid lines (1)

FIG. 3 shows a line (3).

FIG.

[FIG. 3] Both are flattened by a digital camera or an analog camera. Or scan directly. When an analog camera is used, the photographs are digitized by scanning, and taken into a computer. Therefore

Since the line (4) is transformed into the line (5) as shown in FIG. 4, the line and the intersection are recognized to compensate for the deformation of the surface. Here, the design required by the designer is taken into the computer, and when the design required by the designer is transformed so that the line (5) becomes the line (4), the plate required to print the three-dimensional shape by the printing method. Below. Here, for the sake of simplicity,

It is assumed that a grid-like design as shown in FIG.

FIG. 4 shows a line (4). When the surface is distorted so that line (5) becomes line (4), line (4) becomes

FIG. 5 is deformed like a line (6).

When printing is performed on this three-dimensional object using this printing method using an underlay like that shown in FIG.

A print as shown in FIG. 1 is obtained. Here, an example is given in which the three-dimensional shape is a spherical shape, but any three-dimensional shape can be obtained by a single test printing, which shows the deformation bridging, and the underlay of the design required by the designer can be obtained in a correctly distorted state. Therefore, if the printing is performed on the three-dimensional object only once by producing it, the stencil can obtain the design required by the designer. Similarly, when a processing method for deforming a printed material is applied in a single trial production, a stencil for obtaining a design required by a designer is obtained.

[0007]

According to the present invention, it is possible to obtain an appropriate composition for a design required by a designer when performing printing on any three-dimensional object by one-time test printing. Also, with regard to the processing method for deforming the printed matter, it is possible to make an appropriate composition that can obtain the design required by the designer by performing the processing in one trial production in the same way, and try and error It is possible to start mass production early without repeating.
