Abstract: A printed image data generation method includes: a data acquisition step of acquiring data indicating a three-dimensional shape model imitating a printing target object and data indicating a two-dimensional image for decorating a surface of the printing target object; and a printed image data generation step of calculating a position of a surface of the three-dimensional shape model on which ink ejected from a nozzle is to land, determining a pixel of the two-dimensional image corresponding to the position of the surface, and generating data of a printed image to be printed on the printing target object based on information of the pixel.

Abstract: A method for measuring a liquid droplet includes: setting a translucent sample substrate having formed thereon a measurement target liquid droplet on a measurement table having a surface with a recess, the sample substrate being set on the measurement table in an orientation that a side on a back of the liquid droplet corresponds in position to the recess; applying light to the liquid droplet formed on the sample substrate set on the measurement table, imaging the liquid droplet with an imaging section, and measuring quantities of reflected light from the sample substrate and the liquid droplet with the sample substrate having a thickness larger than a wavelength of the light, and equal to or smaller than a focal length of the liquid droplet; and determining a volume or a surface shape of the liquid droplet using the reflected light quantities measured by the imaging section.

Abstract: A liquid droplet measurement method and a liquid droplet measurement device with which the luminance contrast can be improved without making changes in, for example, the numerical aperture of a lens when the quantity of reflected light from the surface of the measurement target liquid droplet alone cannot provide a sufficient luminance contrast. A method and an apparatus for manufacturing a device are also provided. The liquid droplet measurement device includes: a measurement table having a surface with a recess and for holding a translucent sample substrate; an imaging section that applies light onto the sample substrate having formed thereon a liquid droplet, and measures quantities of reflected light from the sample substrate and the liquid droplet; and a measurement control unit that determines a volume or a surface shape of the liquid droplet using luminance information of the reflected light quantities measured by the imaging section.
