A method for printing a printed material on which a pattern corresponding to the decoration of the molded body is used to form a molded body whose surface is decorated by embossing,
On the basis of the three-dimensional data showing the three-dimensional shape of the molded body, and extracting at a plurality of positions of the embossing direction, the contour of the cross section of the green body perpendicular to the direction pushing the mold,
Detecting the overlap of the plurality of contours in a visual field parallel to the embossing direction, and calculating the height of the side wall of the molded body based on the overlap of the contours;
Based on the relationship between the thickness of the coating film of the ink used for printing and the color of the coating film, the portion corresponding to the relatively high side wall in the pattern increases the amount of ink used for printing the pattern. Creating the print data for the design;
Printing on the substrate of the printed material made of resin based on the printing data. Printing by the droplet discharge method,
The printing data is bitmap data that defines pixels that are ink ejection positions used for printing and the ink ejection amount.
The step of creating the printing data corresponds to the side wall for pixels included in a range from a pixel adjacent to the pixel corresponding to the side wall to a pixel separated by a predetermined number of pixels in the bitmap data. Ink ejected to pixels included in the range so as to be larger than the amount of ink disposed in pixels not included in the range excluding the pixels and smaller than the amount of ink disposed in pixels corresponding to the side walls. The printing method according to claim 1, wherein an amount is determined.   3. The printing method according to claim 1, wherein in the step of extracting the contour, an interval between the plurality of positions is an equal interval.
