A method for producing a laminated body including a first curable liquid composition and a second curable liquid composition, the method including: forming a first liquid layer formed of the first curable liquid composition; impacting the second curable liquid composition onto the first liquid layer, to form a second liquid droplet layer formed of the second curable liquid composition inside the first liquid layer or at a lower part of the first liquid layer in a direction in which second liquid droplets for the second liquid droplet layer are impacted onto the first liquid layer; and curing the first liquid layer and the second liquid droplet layer.

Provided is an image processing method for generating print data, the method including an ink amount generating step for generating CMYK data based on image data. The ink amount generating step determines the CMYK data based on a brightness L* calculated using a function f3(D) satisfying f1(D)≥f3(D) in a range of the gradation values D from a coordinates Pk to a coordinates Ps and also satisfying f1(D)≥f3(D) in at least part of the range.

An image processing apparatus includes one or more processors and one or more memories, the one or more memories including one or more programs. The one or more programs cause the one or more processors (a) to acquire first shape data that represents a three-dimensional shape of unevenness, (b) to generate edge data for specifying a first area that corresponds to an edge of a convex portion and a second area that does not correspond to the edge of the convex potion in the unevenness, based on the first shape data, and (c) to generate, based on the edge data, data to form the first area and not the second area on a recording medium.

An ink-jet coater and a coating method for improving smoothness of a mixed part where the coating position in the previous scan overlaps the coating position in the next scan includes a robot arm configured to move a nozzle head unit by driving arms via an arm driving mechanism and a coating control unit configured to control driving of the nozzle driving mechanism and driving of the arm driving mechanism to execute coating on the coating object. The coating control unit performs coating by forming, in segmented coating surfaces formed by each scanning of the nozzle head unit, a normal coating region coated with a target coating film thickness and an overlapping coating region coated with a spray amount of the paint less than the normal coating region.

Printing methods and devices identify distortable ink colors in a print job. These distortable ink colors interact with one another when printed in the same printing pass on the same area of a sheet. These methods and devices control printheads and sheet feeders to separately print the distortable ink colors in different print passes.

A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system comprises an air supply unit comprising an airflow guide structure extending into the opening of the carrier plate, the airflow guide structure configured to flow air at a direction aimed under the printhead and at an oblique angle relative to the movable support surface. The air flow control system controls the air supply unit to selectively flow the air based on a location of a print medium relative to the printhead.

A printing method for printing a printing medium includes a non-white ink application step of applying an aqueous non-white ink composition containing a non-white coloring material onto the printing medium, and a white ink application step of applying an aqueous white ink composition containing a white coloring material onto the non-white ink composition on the printing medium to form a superimposed region. The non-white ink composition and the white ink composition each have an organic solvent content limited to 15% or less relative to the total mass of the corresponding ink composition. The mass ratio of the white ink composition to the non-white ink composition in the superimposed region is 1.5 or more in a portion to which the non-white ink composition is applied in an amount largest in the superimposed region.

A liquid discharge apparatus includes an apparatus body, a liquid discharge device configured to discharge a liquid, a carriage in the apparatus body, the carriage configured to movably mount the liquid discharge device, a first storage container detachably attached to the carriage, the first storage container configured to store a first liquid, and a second storage container detachably attached to the apparatus body, the second storage container configured to store a second liquid different from the first liquid.
