A drawing system according to an embodiment of the present disclosure includes a storage, an operation section, and a drawing section. The storage stores a characteristic function that derives output setting values of light sources on the basis of drawing coordinates, an absorbance correlation value, and gradation values in a leuco color space. The operation section derives the output setting values by inputting, to the characteristic function, the drawing coordinates, gradation values of leuco image data described in the leuco color space, and an absorbance correlation value obtained by measuring the recording medium. The drawing section includes the light sources, and controls output of the light sources on the basis of the output setting values derived by the operation section to thereby perform drawing on the recording medium.

An image-processing apparatus generates data to be outputted to formation unit which form a shaped article on a recording medium. An acquisition unit acquire first shape data that represents a shape of unevenness. A first generation unit generates edge data that represents a shape of an edge of the unevenness, based on the first shape data. A second generation unit generates first recording amount data that represents a recording amount of a first recording material that is used to form at least a part of the edge in the edge data on the recording medium, or first dot arrangement data that represents dot arrangement of the first recording material on the recording medium, based on the edge data.

Printing multi-color images on non-vinyl plastic identification documents in identification document printing systems. A non-linear pixel density adjustment curve is used to adjust the pixel density data of a multi-color image to be printed which adjusts the power applied to the thermal print head. The use of a non-linear pixel density adjustment curve to adjust the pixel density data improves the quality of the resulting multi-color printed image, reduces mass transfer of the dye donor layer, and reduces breaking of the carrier film of the print ribbon.

A light emitting device, includes: a base plate extending in a first direction; multiple light emitting units arranged on a surface of the base plate while being shifted from each other in the first direction, and each including a support body extending in the first direction and multiple light sources supported on the support body while being arranged in the first direction; and a flow path disposed over the surface of the base plate to surround at least part of the light emitting units and allowing air to flow therethrough in the first direction.

An image processing apparatus that generates overcoat transfer data for transferring an overcoat onto an image formed on a recording sheet, generates a line image to be added to the overcoat, and converts the line image into a drawing part to be added to the overcoat. The drawing part includes an outline part and an area inside the outline part, the outline part is formed from pixels having a first glossiness, the area inside the outline part is formed as a mixed pattern part in which pixels having the first glossiness and pixels having a second glossiness higher than the first glossiness are mixed, and the area outside the outline part is formed from pixels having the second glossiness.
