Method of creating proof image data, proof image generation device, and non-transitory computer-readable storage medium storing program

A proof image generation device comprising:

• a basic proof image acquisition unit that acquires basic proof image data for reproducing, by a proof output device, a color distribution of a basic printed matter formed by applying a basic backing to a print fabric obtained by printing an image on a fabric using a printing machine;
• a texture information acquisition unit that acquires four types of texture information based on four types of texture images including (i) an image obtained by imaging a non-print area with no image printed thereon using ink of a fabric for texture acquisition with a first backing as a background, (ii) an image obtained by imaging the non-print area of the fabric for texture acquisition with a second backing having a color different from the first backing as a background, (iii) an image obtained by imaging a print area with an image printed thereon using the ink of the fabric for texture acquisition with the first backing as a background, and (iv) an image obtained by imaging the print area of the fabric for texture acquisition with the second backing as a background;
• an evenness of dye characteristic acquisition unit that acquires evenness of dye characteristic information indicating evenness of dye of the ink in the fabric for texture acquisition using the four types of texture information;
• a transmission characteristic acquisition unit that acquires transmission characteristic information indicating a degree of light transmission of the fabric for texture acquisition using the four types of texture information;
• and
• a texture-added proof image data creation unit that creates texture-added proof image data by applying texture addition processing using the evenness of dye characteristic information and the transmission characteristic information to the basic proof image data.

A non-transitory computer-readable storage medium storing a program, the program for creating texture-added proof image data causing a computer to implement:

• a function of acquiring basic proof image data for reproducing, by a proof output device, a color distribution of a basic printed matter formed by applying a basic backing to a print fabric obtained by printing an image on a fabric using a printing machine;
• a function of acquiring four types of texture information based on four types of texture images including (i) an image obtained by imaging a non-print area with no image printed thereon using ink of a fabric for texture acquisition with a first backing as a background, (ii) an image obtained by imaging the non-print area of the fabric for texture acquisition with a second backing having a color different from the first backing as a background, (iii) an image obtained by imaging a print area with an image printed thereon using the ink of the fabric for texture acquisition with the first backing as a background, and (iv) an image obtained by imaging the print area of the fabric for texture acquisition with the second backing as a background;
• a function of acquiring evenness of dye characteristic information indicating evenness of dye of the ink in the fabric for texture acquisition using the four types of texture information;
• a function of acquiring transmission characteristic information indicating a degree of light transmission of the fabric for texture acquisition using the four types of texture information;
• and
• a function of creating texture-added proof image data by applying texture addition processing using the evenness of dye characteristic information and the transmission characteristic information to the basic proof image data.
