Description

  The present invention relates to a printed material manufacturing method and a printing apparatus.

  2. Description of the Related Art Printing apparatuses that print images on fabrics such as textiles and clothing have been proposed. When printing an image on such a fabric, a method of flattening the fabric surface by fixing the fabric at a predetermined position by air suction or the like can be considered, but air leaks from the fabric texture and the suction force decreases. Resulting in. For this reason, there is known a printing apparatus that prints an image by fixing a fabric in a predetermined position by attaching a backup sheet to one side of the fabric and air-sucking the backup sheet (see, for example, Patent Document 1). ).

JP-A-4-246576

  However, the above-described apparatus has a problem that the manufacturing method becomes complicated because a backup sheet needs to be attached to the fabric before an image is formed on the fabric.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

  Application Example 1 A printed matter manufacturing method according to this application example includes an auxiliary layer forming step of forming an auxiliary layer that closes the eyes of the recording medium, and a region corresponding to the auxiliary layer. It includes a recording medium fixing step of sucking air and fixing the recording medium at a predetermined position, and an image forming step of forming an image on the fixed recording medium.

  According to this configuration, for example, the texture of the fabric is closed by forming the auxiliary layer on the recording medium such as the fabric. Thereby, even if air is sucked into the auxiliary layer, air leakage from the fabric texture is reduced, so that the recording medium can be easily fixed at a predetermined position. Therefore, there is no displacement of the position where the image is formed, and a high-quality printed matter can be provided.

  Application Example 2 In the auxiliary layer forming step of the printed material manufacturing method according to the application example, the ultraviolet curable ink that is the material of the auxiliary layer is applied to the recording medium, and the applied ultraviolet curable ink is applied. The auxiliary layer is formed by irradiating the substrate with ultraviolet rays.

  According to this configuration, the solidified product (resin layer) is formed on the recording medium by applying the UV curable ink and solidifying it. The formed solidified product (resin layer) functions as a resin layer. Therefore, it is possible to easily form an auxiliary layer that closes the eyes of the recording medium.

  Application Example 3 In the recording medium fixing step of the printed material manufacturing method according to the application example, the air is sucked to the surface of the recording medium on which the auxiliary layer is formed, and in the image forming step, the air is The image is formed on a surface of the recording medium opposite to the surface on which the auxiliary layer is formed.

  According to this configuration, since air is sucked in the vicinity of the auxiliary layer, the suction force can be further increased. An image can be formed on the surface of the recording medium opposite to the surface on which the auxiliary layer is formed without being affected by the auxiliary layer. Thereby, a high-quality printed matter can be provided.

  Application Example 4 In the printing apparatus according to this application example, air is sucked into a recording medium from an auxiliary layer forming unit that forms an auxiliary layer that closes the eyes of the recording medium, and an area corresponding to the auxiliary layer. And a recording medium fixing unit that fixes the recording medium at a predetermined position, and an image forming unit that forms an image on the fixed recording medium.

  According to this configuration, for example, the texture of the fabric is closed by forming the auxiliary layer on the recording medium such as the fabric. Thereby, even if air is sucked into the auxiliary layer, air leakage from the fabric texture is reduced, so that the recording medium can be easily fixed at a predetermined position. Therefore, there is no displacement of the position where the image is formed, and a high-quality printed matter can be provided.
