[0045] image 3 It is a diagram showing the configuration of a printer control device 100A according to the first embodiment. image 3 The illustrated printer control device 100A includes a RIP (Raster Image Processor: raster image processor) unit 20, a three-dimensional coordinate generation unit 30, a header data generation unit (print data generation device according to an embodiment of the present invention) 40, and a data transfer / The printing control section 50 .

[0046] The RIP unit 20 receives the image data, and converts the image data for the PC into the image data for the printer. For example, the RIP unit 20 generates image information such as image size and raster data from image data. The RIP unit 20 supplies image information to the three-dimensional coordinate generation unit 30 , and supplies state data to the header data generation unit 40 .

[0047] The three-dimensional coordinate generation unit 30 receives the RIP-processed image data and medium shap...

Abstract

A print data generating apparatus 40 according to an embodiment of the present invention generates print data for a 3D printer that prints on the surface of a medium that has a three-dimensional shape print band by print band. The print data generating apparatus 40 includes a relative curvature calculating means 41 for calculating a relative curvature for each print band relative to a reference print band among the print bands, and an image data thinning means 42 that generates the print data by thinning out image data in each print band according to the relative curvature of the print band.

Description

technical field [0001] The present invention relates to a print data generating device, a print data generating method, and a print data generating program for generating print data for a three-dimensional printer that prints an image on a three-dimensionally shaped medium surface. Background technique [0002] Patent Document 1 describes a three-dimensional printer that prints an image on a three-dimensionally shaped medium surface. Patent Document 1 describes a three-dimensional printer that prints an image on the surface of a medium by rotating the medium relative to the X-axis (B-axis) in the XYZ rectangular coordinate system, and describes the following problem: The appearance of the image on the spherical printing surface of the medium is deformed to gradually shrink toward the outer peripheral direction (Y direction) of the spherical printing surface. [0003] Regarding this problem, Patent Document 1 describes that the distortion of the image printed on the spherica...
