  However, in order to express or reproduce the above-described works with a more realistic texture, there are the following problems. That is, for example, as a characteristic of oil painting, it is common to paint three-dimensionally by thickly painting. Therefore, when creating an oil painting-like work as a printed matter from the original image, the surface shape is not flat but has irregularities, and the image edited image is printed on a thick print medium, A home printer cannot print well. This is because a standard for printing media that can be printed on home printers is defined. If the surface shape is not flat due to the mechanism of the printer, or an image is printed on a printing medium with a specified thickness or more. In many cases, the desired texture cannot be expressed or reproduced. As a method for solving such a problem, for example, there is a method of printing a stereoscopic image by scanning and recoating an image a plurality of times using a business inkjet printer using a high viscosity ink, etc. In this case, it takes time and money, and it is not easy for general use.

  In addition, other than oil painting works, for example, when creating an original image that has been edited and processed in a watercolor style, colored pencil style, pastel style, etc., a home printer has a touch in each style. It was difficult to express or reproduce a feeling of unevenness such as brush stroke (writing), that is, a unique texture.

FIG. 2 is a schematic plan view showing an embodiment of the printing surface processing method according to the present invention, and FIG. 3 is a schematic cross-sectional view showing a processing state in the printing surface processing method according to the present embodiment. In addition, the specific image formed in the back surface side of the thermally expansible sheet shown in FIG.2 (b), the uneven | corrugated pattern formed in the surface side of the thermally expansible sheet shown in FIG.2 (c), and desired The strokes and strokes in the style of painting, and the expansion (foaming) state of the thermal expansion layer shown in FIG. 3 (d) are shown for convenience of explanation and conceptually, and show the actual state. It is not a thing.

  As shown in FIG. 1, the printing surface processing method according to the present invention is roughly divided into an image data generation process (S101), a front surface image formation process (S102), a back surface image formation process (S103), light irradiation / heating. Processing (S104). Here, in the printing surface processing method according to the present embodiment, for example, as illustrated in FIG. 2A, a color image 33 including a dog image and a mountain image is printed on the surface side of the thermally expandable sheet 30. A case will be described in which a desired texture is expressed or reproduced by processing a plurality of types of different surface shapes or textures drawn with a plurality of types of different touches or strokes.

  In the image data generation process (S101), first, image data of the color image 33 (edited and processed into a desired style (for example, a specific brushstroke or stroke expression) using an image conversion software or an image conversion service) Surface image data) and a thermally expandable sheet (or thermally foamable sheet) 30 are prepared as print media for printing the color image 33. Here, as shown in FIG. 3A, for example, the thermally expandable sheet 30 is roughly expanded on the one surface (upper surface in the drawing) side of the base sheet 31 and contains expandable microcapsules that expand by heating. This is a print medium on which a layer (or foam layer) 32 is formed by coating. The thermally expandable sheet 30 applied in the present embodiment is a print medium that is one surface side of the thermally expandable layer 32, has a substantially flat surface shape, and can be printed by a general household printer. Is within the scope of the standard. The chromatic image 33 is a color image having an arbitrary pattern (corresponding to the patterns 33a to 33c shown in FIG. 3A), such as a dog image or a mountain image shown in FIG. It may be a monochrome image or a monotone image.

  Next, when creating a work by forming the color image 33 on the surface of the thermally expandable sheet 30 (one surface of the thermally expandable layer 32), specify a desired texture to be expressed or reproduced in the work, Image data (back surface image data) of the specific image 34 formed on the back surface (the bottom surface of FIG. 3B; the other surface of the base sheet 31) of the thermally expandable sheet 30 is generated.

  Specifically, among the colored images 33 shown in FIG. 3A, the pattern 33a of the dog image and the patterns 33b and 33c of the mountain image are expressed or reproduced by, for example, an oil painting-like brush touch or brush with a highly raised paint. In addition, when the background image portion 33g other than the image portion is expressed or reproduced with the texture as depicted on the canvas, the thermally expandable sheet on which the images 33a to 33c of the dog and mountain images are printed. In the region on the surface side of 30, an uneven surface shape that is similar or similar to the touch and stroke of the image style is formed, and in the region on the surface side of the thermally expandable sheet 30 on which the background image portion 33 g is printed, The image data of the specific image 34 is generated so that a fine uneven surface shape that is similar to or similar to the yarn pattern representing the canvas canvas is formed.

  Here, the method of forming the surface shape of an arbitrary texture on the surface of the thermally expandable sheet 30 expresses or reproduces the desired brush touch or brush texture in the pattern 33a to 33c of the dog image and the mountain image. From the grayscale image (monochrome grayscale image) in which the arrangement and density of the dark color portion and the light color portion of the black component are set so as to correspond to the uneven pattern on the surface of the thermally expandable sheet 30 as shown in FIG. The image areas 34a to 34c to be set are set. Further, in the background image portion 33g, as shown in FIG. 3B, the dark color portion and the light color of the black component correspond to the uneven pattern on the surface of the thermally expandable sheet 30 that expresses or reproduces the texture of the canvas. An image region 34g composed of a grayscale image in which the part arrangement and density are set is set. And the specific image 34 which consists of these image area | regions 34a-34c and 34g is formed in the surface of the thermally expansible sheet 30 by forming in the back surface side whole region of the thermally expansible sheet 30, and performing arbitrary expansion | swelling. A textured surface shape is formed.

  In the present embodiment, the black component forming the above-described grayscale image is not limited to black as a coloring, and heat energy is absorbed by absorbing light including an infrared wavelength (which generally means a far-infrared wavelength). It means a material having generated photothermal conversion characteristics. As a material having such photothermal conversion characteristics, for example, carbon black can be applied.

  In the image data generation process of the specific image 34, the user can arbitrarily adjust the arrangement and density of the dark and light color portions of the image areas 34a to 34c and 34g forming the specific image 34. It may be a thing. Thereby, in the pattern 33a-33c of the image of a dog and the image of a mountain, the uneven | corrugated pattern (for example, a wavy pattern corresponding to a handwriting, a stipple pattern etc.) of the surface of the thermally expansible sheet 30 which expresses or reproduces a touch and a handwriting texture. It is possible to arbitrarily set the length and fineness, the degree of swell of the paint, and the like. In addition, in the background image portion 33g, it is possible to arbitrarily set the roughness and the protruding height of the uneven pattern on the surface of the thermally expandable sheet 30 that expresses or reproduces the texture of the canvas (that is, the thread pattern of the painting cloth). .

  Next, in the surface image forming process (S102), as shown in FIGS. 2 (a) and 3 (a), the image data generating process (S101) was prepared on the surface side of the thermally expandable sheet 30. Based on the image data of the chromatic image 33, the chromatic image 33 having the images 33a to 33c of the dog image and the mountain image and the background image portion 33g is printed (formed). Specifically, as shown in FIG. 3A, on the surface of the thermally expandable sheet 30 (one surface side of the base sheet 31; the upper surface side of the drawing), as shown in FIG. And a color image 33 composed of a mountain image is printed. Here, for printing the color image 33 on the surface side of the thermally expandable sheet 30, various types of printing apparatuses such as an ink jet system, a laser system, and a thermal transfer system shown in a printing surface processing apparatus described later are applied. Can do.

  Next, in the back surface image forming process (S103), as shown in FIG. 2B and FIG. 3B, the back surface side of the thermally expandable sheet 30 is generated in the image data generating process (S101). Based on the image data, a specific image 34 composed of a monochrome grayscale image is printed (formed). Here, the region corresponding to the pattern 33a to 33c of the dog image or the mountain image formed on the surface side of the thermally expandable sheet 30 is dark so as to express or reproduce a desired brush touch or handwriting texture. The image areas 34a to 34c in which the arrangement and density of the color part and the light color part are set are printed, and the dark color part is expressed in the area corresponding to the background image part 33g so as to express or reproduce the texture of the canvas. And an image area 34g in which the arrangement and density of the light color portion are set. Note that the image areas 34a to 34c may also be expressed or reproduced with a desired handwriting or handwriting texture and the canvas texture in order to be expressed as an image formed on the canvas. At this time, the specific image 34 printed on the back surface side of the thermally expandable sheet 30 has a mirror image relationship that is an inverted image of the color image 33 printed on the front surface side. Here, the specific image 34 formed on the back surface side of the thermally expandable sheet 30 is formed by ink or toner containing a black component. Also, in printing the specific image 34 on the back surface side of the thermally expandable sheet 30, various types of printing apparatuses such as an ink jet system, a laser system, and a thermal transfer system shown in a printing surface processing apparatus described later are applied. Can do.

  Next, in the light irradiation / heating treatment (S104), as shown in FIG. 3C, the light LT including the infrared wavelength is uniformly irradiated from the back surface side of the thermally expandable sheet 30. As a result, thermal energy corresponding to the density is generated in the dark and light color portions of the monochrome light and shade image forming the specific image 34 formed on the back surface side of the thermally expandable sheet 30, and the thermal expansion in the corresponding region. When the microcapsules of the layer 32 are heated and expanded (foamed), the thermally expanded layer 32 is raised. Here, as described above, the specific image 34 is an oil painting style in which the image regions 34a to 34c corresponding to the patterns 33a to 33c of the dog image and the mountain image in the chromatic image 33 are raised, for example. Since the arrangement and density of the dark color part and the light color part are set so as to express or reproduce the texture of the touch and the brush stroke, as shown in FIG. 3D, the thermal expansion after the thermal expansion layer 32 is expanded. On the surface of the conductive sheet 30, a concavo-convex pattern having a handwriting and a raised height is formed so as to correspond to the touch and the texture of the brush stroke in the desired image style. In addition, since the arrangement and density of the dark color portion and the light color portion are set so that the image region 34g corresponding to the background image portion 33g in the color image 33 expresses or reproduces the texture of the canvas, As shown in FIG. 3 (d), the surface of the thermally expandable sheet 30 after the expansion of the thermal expansion layer 32 has a concavo-convex pattern having a predetermined roughness and raised height so as to correspond to the texture of the canvas. Is formed.

  In the description of FIGS. 1 to 3, in this embodiment, in the present embodiment, image data generation processing (S101), front surface image formation processing (S102), back surface image formation processing (S103), light irradiation / heating processing (S104). However, the order of processing is not limited to this. That is, in the image data generation process (S101), image data (front surface image data) of the chromatic image 33 and image data (back surface image data) of the specific image 34 corresponding thereto are first prepared for generation. As the order of the forming process, either the front surface image forming process (S102) or the back surface image forming process (S103) may be processed first. That is, in the printing surface processing method of the present invention, the processing order is not specified.

  Therefore, according to the present embodiment, as shown in FIG. 3D, the surface shape of the thermally expandable sheet 30 on which the desired color image 33 is printed on the surface side is changed according to the pattern of the color image 33. It can be processed to have a plurality of different textures. For example, as shown in FIG. 2 (c), a colored image 33 is a pattern of a dog image and a mountain image on a background image portion 33g of a canvas. It is possible to create a work that is expressed or reproduced with a texture such as that depicted by the brushes and brush strokes in which the paints 33a to 33c are raised.

  In the present embodiment, among the colored images 33, the pictures 33a to 33c of the dog image and the mountain image are expressed or reproduced with an oil painting-like brushstroke or brush with a high paint, and the background image portion 33g. Although the case where it is expressed or reproduced with the texture as depicted on the canvas has been described, the present invention is not limited to this. In other words, any area in a colored image may be expressed or reproduced with a texture different from that of other areas. For example, a texture such as a pastel-style object drawn on a watercolor background Alternatively, it may be expressed or reproduced with a texture or the like in which an object in an oil painting style is drawn on a background in which a watercolor style and a colored pencil style are mixed. According to this, it is possible to realize a variety of expression methods by combining various styles of paintings, touches and textures in one piece of work, and to enhance the user's preference.
