    • PROBLEM TO BE SOLVED: To allow a user to properly read printed matter formed by overlapping a color image and a photoluminescent underlayer on each other.SOLUTION: A printing apparatus includes: a first nozzle that discharges color ink to form a first dot; a second nozzle that discharges at least one of white ink, clear ink, and first photoluminescent ink to form a second dot; and a third nozzle that discharges second photoluminescent ink, having diffuse reflectance lower than that of the ink discharged from the second nozzle, to form a third dot. The printing apparatus is configured to form an image visually recognized from the side opposite to the image forming side via a medium to be printed in the following manner. A color image by the first dot is formed on the medium to be printed. The second dot is formed on the first dot constituting the color image. Then, a photoluminescent underlayer by the third dot is formed on the color image and the second dot.
    • 要解决的问题:为了使用户能够正确地读取通过将彩色图像和光致发光底层重叠在一起而形成的印刷物。解决方案:打印设备包括:排出彩色墨水以形成第一点的第一喷嘴; 排出白色墨水,透明墨水和第一光致发光墨水中的至少一种以形成第二点的第二喷嘴; 以及排出第二光致发光墨的第三喷嘴,其具有比从第二喷嘴排出的墨的漫反射率更低的散射反射,形成第三点。 打印装置被配置为通过以下方式经由要打印的介质从与图像形成侧相对的一侧形成视觉识别的图像。 在要打印的介质上形成由第一点形成的彩色图像。 第二点形成在构成彩色图像的第一点上。 然后,在彩色图像和第二点上形成由第三点形成的光致发光底层。
