摘要： A multilayered printed matter includes a group of print layers formed on a medium. The group of layers include a front layer and a back layer on which patterns are printed, a white layer, and a black layer. The white layer is interposed between the front layer and the back layer to conceal the back layer to be invisible from the side of the front layer. 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.

摘要： A printing system is provided and includes an image processing portion that generates a generated image by image processing, and a printing portion that performs printing on a medium based on the generated image. The image processing portion generates the generated image by performing a quantization processing that performs quantization by comparing the pixel value of each pixel in the input image with a threshold, and in the quantization processing, calculates a dot influence value indicating to what extent a position corresponding to a selected pixel is covered by the ink dots formed at the position set on the medium in correspondence with the peripheral pixels of the selected pixel, performs adjustment of reflecting the dot influence value on at least one of the pixel value of the selected pixel or the threshold, and compares the pixel value and the threshold based on a value after adjustment.

摘要： In an inkjet printer, an ultraviolet irradiator includes a first irradiation portion disposed at the same position as a color ink ejection portion in a front-back direction and a third irradiation portion disposed on the front side of a clear ink ejection portion in the front-back direction, where at the time of printing in a gloss tone printing mode, an average illuminance of a fifth irradiation portion that forms the front side portion of the first irradiation portion is lower than an average illuminance of a fourth irradiation portion that forms the back side portion of the first irradiation portion.

摘要： A liquid ejection device includes a liquid ejection head having a nozzle surface provided with an ejection port of a nozzle from which a liquid is ejected, a cap that comes into contact with the nozzle surface to cover the nozzle, an air pressure adjuster that adjusts an air pressure inside the cap when the cap is in contact with the nozzle surface, and a contact force adjuster that sets, equal to a first pressure, a contact force that is a pressure causing the cap to come into contact with the nozzle surface when the air pressure adjuster sets the air pressure inside the cap equal to a first air pressure, and sets the contact force equal to a second pressure lower than the first pressure when the air pressure adjuster sets the air pressure inside the cap equal to a second air pressure higher than the first air pressure.

摘要： 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.

摘要： An inkjet printer includes a control unit that counts the number of retries of communication between the control unit and a storage device and communication between the inkjet printer and a host computer and records the same in the storage unit. The control unit can also derive an installation environment level of the installation environment of the inkjet printer based on at least one number of retries recorded in the storage unit, and output the derived installation environment level to a display unit.

摘要： A method for manufacturing a three-dimensional object is provided. The method reduces the difference between the amount of build material used and the amount of decorative ink used. The method for manufacturing a three-dimensional object including an object body portion (A) and a decorative portion (C) is provided. The method includes forming the object body portion (A) from at least decorative ink and build material and forming the decorative portion (C) from the decorative ink. The decorative portion (C) covers the object body portion (A).

摘要： An up-down moving mechanism includes a support member; an up-down moving member that is formed separately from the support member and can be moved up and down with respect to the support member; a screw shaft for moving up and down the up-down moving member; a nut member that is screwed onto the screw shaft; a guide rail that guides the up-down moving member in a vertical direction; a guide block that slidably engages with the guide rail; and a gas spring that includes a cylinder and a piston rod biased in a direction projecting out from the cylinder, and that biases the up-down moving member toward an upper side with respect to the support member. To the support member, the screw shaft is rotatably attached, the guide rail is fixed, and the piston rod is attached.

摘要： A multilayered printed matter is made up of a plurality of layers formed on a medium, including a front layer and a back layer with patterns printed thereon, and a white layer and a black layer interposed between the front layer and the back layer so as to conceal the back layer to be invisible from the front-layer side. The system for producing the multilayered printed matter includes a computer that executes a printing step of moving the medium and an inkjet head relative to each other using a moving device and printing the front, back, white, and black layers on the medium using the inkjet head, and a cutting step, subsequent to the printing step, of moving the medium and a cutting blade relative to each other using the moving device and cutting the medium using the cutting blade.

摘要： A printing device performs printing through an inkjet system includes an inkjet head, an ultraviolet irradiator, and a controller. An ink ejected by the inkjet head contains a curable substance and a solvent. The controller is configured to: cause the inkjet head to perform an ejecting operation; cause the ultraviolet irradiator to perform a viscosity increasing operation and a curing operation; cause, in the viscosity increasing operation, the ultraviolet irradiator to irradiate the ink with ultraviolet light to evaporate at least a part of the solvent in the ink by heat of polymerization and increase the viscosity of the ink to a viscosity at which smearing does not occur on the medium; and cause, in the curing operation, the ultraviolet irradiator to irradiate the ink with ultraviolet light to cure the ink on the medium.
