Abstract: Provided are an inkjet printing method and an ink set, in which forward and reverse warp inks are printed in an arrangement that reduces warp. The forward warp ink is the ink in which a warp when cured and shrunk by irradiation of light is a forward warp in which a portion on a side where light is irradiated by a light irradiation device is large in the degree of curing and shrinkage as compared with a portion on an opposite side. The reverse warp ink is the ink in which a warp when cured and shrunk by irradiation of light is a reverse warp in which a portion on a side opposite to a side where light is irradiated by the light irradiation device is large in the degree of curing and shrinkage as compared with a portion on the side where light is irradiated.

Abstract: A multilayered body includes a base material with a metal tone glossy layer having metal tone glossiness, and a color layer layered on the metal tone glossy layer. The color layer has an arithmetic mean height and a transmission density located in a region below a straight line represented as (y=?0.1067x+0.8) on coordinates of the arithmetic mean height x and the transmission density y.

Abstract: An inkjet printer includes an inkjet head that ejects ink droplets, and a sub tank that stores an ink to be supplied to the inkjet head, where the sub tank is provided with an ink outflow port through which the ink flows out from the sub tank, and an ink inflow port through which the ink that flowed out from the ink outflow port and passed through a predetermined circulation path flows toward the sub tank. In the inkjet printer, the ink is flowed out from the ink inflow port and the ink that passed through the circulation path is flowed into the sub tank from the ink outflow port at a predetermined timing.

Abstract: The present disclosure prevents a visible pattern corresponding to the pattern of a mask from being noticeable and enables more appropriate printing. 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.

Abstract: A manufacturing method for a decorated object is provided. In this manufacturing method, a foil is attached to a medium to obtain the decorated object. The manufacturing method includes: a foil layer forming step of attaching the foil to an adhesive layer formed on the medium, so as to form a foil layer in a manner that the adhesive layer is partly exposed; and an ink layer forming step of applying an ink to the foil layer on which the adhesive layer is partly exposed, so as to form an ink layer in a manner that the ink contacts an exposed part of the adhesive layer.
