Abstract

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.

The white layer reflects incident light from the side of the front layer to allow the front layer to be visible from the side of the front layer. The black layer is interposed between the white layer and the back layer to conceal the back layer to be invisible from the side of the front layer. In comparison between the black layer and the white layer that are equal in thickness, the black layer exerts a higher light blocking effect than the white layer.

Abstract

A manufacturing method for a shaped object for manufacturing the shaped object used as a parts when creating a three-dimensional object assembled by combining multiple parts, where the shaped object including a surface region, an end region, and an inner region is shaped. A surface colored portion, which is a portion to be colored in the surface region, is formed, so that a light entering from a side opposite to the inner region is reflected by the inner region to an outside of the shaped object. And, an end colored portion, which is a portion to be colored in the end region, is formed to have a light reflectivity higher than that of the surface colored portion using a coloring material and a light reflective material.

A printing apparatus 10 performing printing by an inkjet scheme includes: an inkjet head 102; and a controller 20, configured to control the operation of a main scan driver 16 and a sub scan driver 18 to perform a main scanning operation multiple times on each position on a medium 50. In the main scanning operation, for at least part of ejection positions serving as ejection targets of ink droplets in the main scanning operation, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a mask for selecting part of the at least part of ejection positions. In the main scanning operation at one time, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a preset first mask. In the main scanning operation at another time different from the one time, the controller 20 causes the inkjet head 102 to eject an ink droplet in accordance with a second mask for selecting an ejection position in a pattern different from the first mask.

Abstract

A printing device prints an object on a medium by inkjet printing. The printing device includes: a glossy ink head that discharges ink droplets of a glossy ink having a glossy color; and a main scan driver that prompts the glossy ink head to perform main scans in which the glossy ink head discharges the ink droplets while moving in a predetermined main scanning direction. The glossy ink contains a glossy pigment. In the main scans, the glossy ink head discharges the ink droplets plural times while moving in the main scanning direction to form ink dots at positions on the medium aligned in the main scanning direction. The ink droplets discharged from the glossy ink head each have a volume constituting a size that allows for contact on the medium between any ones of dots formed in each one of the main scans.

Abstract

A printing method and a printing apparatus are provided. After ink droplets of a photocurable ink are landed on a print medium, a scan of applying a light to cure the ink droplets to form dots is performed alternately in a forward direction and a backward direction with respect to a predetermined unit region, and a time from landing to curing of the ink droplets onto the print medium differs between the forward direction and the backward direction. The printing method includes: providing the ink droplets that include: a large dot having a large amount of ink per droplet, and a small dot having a smaller amount of ink per droplet than that of the large dot; and controlling ejection of the ink droplets, such that number of passes when forming the large dot is greater than number of passes when forming the small dot, when forming a print image.
