The printed article includes a medium having a specular reflective layer, a first line composed of a first color formed at the medium, a second line formed at the medium in a second color and formed parallel to the first line, and a prism layer formed onto at least the first line, wherein when the medium is divided into a first region, a second region, and a third region that are continuous in parallel, the first line is disposed in any one region of the first region, the second region, and the third region, the second line is disposed in any one region other than the region where the first line was formed, the prism layer is disposed across two contiguous regions including the region formed with the first line, and the section of the prism layer has a shape of a portion of the non-circular arc approximating the ellipse.

In this print method, assuming that the number of stacking of ink layers in a thickest portion in a thickly-piled portion is N, in a histogram preparation step ST2, a histogram of luminance values of grayscale image data prepared in an image data preparation step ST1 is prepared, and in luminance value range setting steps ST3 to ST10, a luminance value of predetermined gradations of the histogram is divided into N and N luminance value ranges are set. In the luminance value range setting steps ST3 to ST10, a division position of the luminance value of the predetermined gradations is adjusted while the histogram displayed on a predetermined display is checked.
