A raised shape is appropriately formed on a medium. A printing deviceincludes inkjet headstothat are a plurality of color ink heads, an inkjet headthat is a light reflective ink head, and a controller. The controllercauses the inkjet headstoand the inkjet headto form a layered ink region and an image region on the medium. The layered ink region is a region including a plurality of colored regions (four-color regions) that are colored regions formed by causing at least two inkjet heads among the plurality of inkjet headstoto eject ink, and a plurality of white layers that are light reflecting regions formed on the colored region. The colored regions in the layered ink region are superimposed with at least the white layer interposed therebetween.

Printing device and printing method

A method for generating ejection position data indicating an ejection position where ink is ejected includes performing an edge detection process, an edge correction process, and an ejection position data generation process based on processing target data indicating an image to be printed. In the processing target data, a non-ejection value indicating that ink is not ejected to a corresponding ejection position or an ejection value other than the non-ejection value is set as a pixel value of a pixel. In the edge detection process, a position where a pixel to which the non-ejection value is set and a pixel for which the ejection value is set are adjacent is detected to detect an edge. In the edge correction process, the pixel value of the corresponding pixel is changed to a non-ejection value for at least a part of the ejection position where ink is ejected to draw the edge.

Method for generating ejection position data, device for generating ejection position data, and program

In a three-dimensional shaping device, a support layer includes a dissolution removal target region removed by dissolving in the predetermined liquid and formed at a periphery of at least one part of the three-dimensional shaped object, and a non-dissolution removal target region removed through a method other than dissolution by the predetermined liquid and formed at a periphery of at least one part of the dissolution removal target region. At least one part of the support layer other than the dissolution removal target region is a different material region which is a region formed using a material different from the dissolution removal target region, and is formed at a position of at least one part of the periphery of the dissolution removal target region to indicate a position of a boundary between the dissolution removal target region and the non-dissolution removal target region.

Three-dimensional shaping device and manufacturing method for three-dimensional shaped object

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 STa 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 STto STa 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 STto STa division position of the luminance value of the predetermined gradations is adjusted while the histogram displayed on a predetermined display is checked.

Print method

A shaping system that shapes a stereoscopic shaped object, the shaping system including a control PC and a shaping device serving as a shaping executer, where the control PC includes a three-dimensional data inputter that accepts an input of three-dimensional data, which is data indicating at least a stereoscopic shape of the shaped object, and a surface data processor that generates decorated shaped object data, which is data indicating the shaped object on which decoration indicated by decoration data has been applied based on the decoration data which is data indicating decoration to be applied on at least a part of the surface of the shaped object and the three-dimensional data, and the shaping device executes a shaping operation of the shaped object based on the decorated shaped object data to shape the shaped object on which decoration indicated by the decoration data has been applied.
