An ink jet recording apparatus according to the present invention includes: a conveying unit that conveys a recording medium; a pretreatment unit that performs corona treatment on a surface of the recording medium; an ink image forming unit configured to be able to form an ink image by applying an ink of at least two colors, the ink containing an anionic pigment; a brightness measuring unit that measures brightness of the ink image; and a corona treatment intensity changing unit configured to change a corona treatment intensity of the pretreatment unit based on a result of the brightness measuring unit.

A coating device, comprising a supply roller having a first contact surface, and a counter-roller placed opposite the supply roller and a second contact surface substantially parallel to the first contact surface. The contact surfaces are at least a substrate width in width and maintain a mutual gap for receiving the substrate therein in contact with both contact surfaces. The supply roller and counter-roller are each rotatable about their central axis. A liquid is supplied to the supply roller. At least the contact surface of the supply roller or the counter-roller is axially adjustable along the central axis thereof. Adjusting means align an edge of the contact surface of the supply roller and the counter-roller with a side of the substrate. An opposite edge of the other of the supply roller and the counter-roller is aligned with an opposite side of the substrate.

The disclosure more appropriately determines a condition of a step executed at the time of creating a product of printing. A printing system (10) that creates a product of printing by performing at least printing includes a printer (16) which is a printing apparatus that executes a printing step of performing printing by ejecting ink; a washing machine (20) which is a post-processing machine that executes a post-processing step on a printed matter obtained by performing the printing step in the printer (16); and a control device (12) that determines a condition of a post-processing step based on a condition of the printing step.

Embodiments of the invention relate to a method of indirect printing with an aqueous ink. Related apparatus, systems and treatment formulations are disclosed herein. Some embodiments relate to an aqueous treatment formulation for use with an intermediate transfer member of a printing system. In some embodiments, the system comprises a treatment station disposed downstream of the impression station and upstream of the image forming station for forming a uniform thin layer of a liquid treatment formulation onto a surface of an intermediate transfer member (ITM) at a lower run thereof.

A recording apparatus includes a conveying unit, a supporting unit, and a static elimination unit. The conveying unit conveys a recording medium in a first direction to a recording area where recording is performed by a recording unit. The supporting unit supports the recording medium conveyed by the conveying unit and includes an abutment surface that abuts the recording medium when the supporting unit supports the recording medium. The static elimination unit eliminates static from the recording medium in a static elimination portion. The static elimination portion is not provided at a position opposed to the abutment surface and is provided at a position not opposed to the abutment surface in the supporting unit.

An image forming apparatus includes: a pretreatment section that applies a precoat liquid to a printing surface of a continuous recording medium to be transported; a printing section that sprays ink onto the continuous recording medium to which the precoat liquid is applied; and a transport section that transports the continuous recording medium along a predetermined path. The transport section includes at least one pass roller that is disposed between the pretreatment section and the printing section, the pass roller transporting the continuous recording medium to which the precoat liquid is applied toward the printing section and coming into contact with the printing surface of the continuous recording medium. A surface of the pass roller is subjected to water-repellent finishing for the precoat liquid.

Systems and methods for forming and applying decorations onto substrates are disclosed. According to some aspects, a decoration may be formed on a carrier web at a decoration forming station positioned along a web path. The decorations may be transported along the web path to an application station at which the decorations are applied to substrates from the carrier web.

A panel repairing method includes detecting a defective portion of a panel, providing primary ink, which is ejected from an ink ejection pin, onto a first portion of the defective portion, spreading the primary ink in a direction parallel to a plane defined on the panel, temporarily curing the primary ink, providing secondary ink, which is ejected from the ink ejection pin, onto a second portion of the defective portion disposed adjacent to the first portion, and curing the primary ink and the secondary ink.

A recording device includes: a medium accommodation portion configured to accommodate a plurality of media; a feeding portion configured to send out the media from the medium accommodation portion; a recording section configured to perform recording on the media sent out from the medium accommodation portion; an ultraviolet-light emitting portion provided at a position opposed to the medium accommodation portion and configured to emit ultraviolet light toward the media accommodated in the medium accommodation portion; and a control unit configured to control the ultraviolet-light emitting portion to emit ultraviolet light to the media by utilizing a period before the feeding portion starts to feed the media.

A recording apparatus includes a recording unit configured to perform recording, an operation panel including an operation unit and a button unit configured to perform an input operation, an ultraviolet irradiation unit configured to directly irradiate the operation panel with ultraviolet rays, a sensor configured to detect presence of a person; and a controller, wherein the controller causes the ultraviolet irradiation unit to emit ultraviolet rays when the sensor detects presence of a person.
