A control method of a liquid ejection device having an ejection unit, and a maintenance unit for maintaining the ejection unit, the ejection unit having a first head having a first nozzle configured to eject the liquid, and a second head having a second nozzle configured to eject the liquid and a third nozzle configured to eject the treatment liquid, the maintenance unit having a first receiving portion configured to receive the liquid, and a second receiving portion configured to receive the treatment liquid, and the control method includes executing a first flushing in which the liquid is ejected from the first nozzle to the first receiving portion, executing a second flushing in which the liquid is ejected from the second nozzle to the first receiving portion, and executing a third flushing in which the processing liquid is ejected from the third nozzle to the second receiving portion.

Provided is an ink jet recording method capable of recording an image with suppressed unevenness when an image is recorded on a low absorbable recording medium by a single pass system. The method is an ink jet recording method for recording an image on a low absorbable recording medium using an aqueous ink and an aqueous reaction liquid containing a reactant reacting with the aqueous ink by carrying out application of the ink and the reaction liquid by a single pass system. The method includes an ink applying step to apply the reaction liquid to the recording medium, and a reaction liquid applying step to apply the ink to the recording medium so that a region to which the aqueous ink is applied and a region to which the reaction liquid is applied are at least partially overlap on the recording medium.

A method for manufacturing printed products contains the steps of applying at least one colored and water-containing ink to image regions on a printing material in a drop-on-demand process. An essentially colorless and water-containing liquid is applied a) to non-image regions and/or b) to image regions that have only little ink in the drop-on-demand process. The printing material is dried. The printing material has a coating that contains at least one acid. After the application of ink and the application of a liquid, a water-containing further liquid, for instance a varnish, is applied both to image regions and to non-image regions of the printing material, and that the liquid and/or the further liquid contains at least one substance that at least partly neutralizes the acid. The undesired formation of waves and glossiness fluctuations between varnished image regions and varnished non-image regions may thus advantageously be avoided.

Examples described herein include examples methods for generating varnish knockouts that include applying a fixer material to a surface of a print medium, selectively applying a print material over the fixer material to form an image, and applying an overcoat material to form a durable coating on areas over the image and a nondurable coating over other areas of the surface.

An image forming method uses an apparatus for forming an image on both recording media of fabric and recording paper. The image forming method includes: applying a treatment agent to the fabric, the treatment agent coagulating a water-based ink or increasing viscosity of the water-based ink; and discharging the water-based ink onto the fabric by an ink-jet system, the water-based ink being identical to a water-based ink used for forming the image on the recording paper.

In one example of the disclosure, a system includes a chamber having an inlet to receive a print agent, an actuator operatively connected to the chamber, and a set of nozzles fluidly coupled to the chamber. The nozzles are orientated such that each nozzle of the set has a same boundary condition.

A printed material of the present invention is a printed material including a recording medium, a color material layer, and a fine irregular layer functioning as an outermost layer in this order; the color material layer contains a pigment; the fine irregular layer contains spherical particles having a specific average particle diameter; the spherical particles are present in a thickness direction of the fine irregular layer; and the surface of the fine irregular layer has convex portions having an average height of 0.04 to 0.15 m and an image definition C(2) is 50% or more.

There is provided a reaction liquid to be attached to a recording medium to which an ink composition is to be attached, the reaction liquid including an aggregating agent which aggregates components of the ink composition, water, and a surfactant, in which a content of the surfactant is 2% by mass or more and 10% by mass or less with respect to a total mass of the reaction liquid.

An inkjet treatment liquid contains emulsified particles containing a silicone oil and an aqueous medium, in which a percentage content of the silicone oil is 7% by mass or more and 15% by mass or less.

A method for digital printing of single or multiple color graphics and/or text on flexible and semi-rigid packaging materials comprising: digitally pre-printing on a sheet or roll of paper, polyethylene or other material, or digitally post printing on a bag, pouch, or sheet of material by depositing a thin layer of ink or toner onto a packaging material surface to form an image, and then adhering the ink or toner to the packaging material surface by use of a fuser fluid, heat, UV curing process, or any combination.
