A substrate preparation chamber is described herein. The substrate preparation chamber comprises an enclosure, a rotatable substrate support disposed within the enclosure, and an atmosphere replacement system coupled to the enclosure. The substrate preparation chamber can be used with an inkjet printing system, where the substrate preparation chamber is coupled to a printing enclosure such that a door is operable to place the enclosure of the substrate preparation chamber in fluid communication with the printing enclosure.

A method for producing a printed material includes providing pressure-induced phase transition particles on a recording medium having an arithmetic average roughness Ra of 0.07 μm or more and 3.80 μm or less to form a pressure-induced phase transition particle layer having a coverage C within a range of 30% to 90%; bonding the pressure-induced phase transition particles onto the recording medium; and folding the recording medium having the pressure-induced phase transition particles bonded thereon and pressure-bonding the folded recording medium, or pressure-bonding the recording medium having the pressure-induced phase transition particles bonded thereon and another recording medium placed on top of each other. The pressure-induced phase transition particles have at least two glass transition temperatures, and the difference between the lowest glass transition temperature and the highest glass transition temperature among the glass transition temperatures exhibited by the pressure-induced phase transition particles is 30° C. or more.

A staged printing system includes: a printing station for printing an image upon an object; a curing station, operatively connected to the printing station, for curing the image printed upon the object; and a pretreatment station, operatively connected to the printing station, for pretreating the object before printing an image upon the object. The printing station includes a plurality of vertically mounted print heads for ejecting ink and a rotating platform for rotating the object as the plurality of vertically mounted print heads eject ink upon the object.

A printing apparatus includes: a printing unit which performs printing on a medium, a main body; a conveyer which conveys the medium; a post-processing unit which performs a post-processing for the medium on which the printing has been performed by the printing unit; a first cover rotatably supported by the main body and in which at least the post-processing part is installed; a second cover arranged to be adjacent to the first cover and supported by the main body such that the second cover is rotatable coaxially with the first cover; and an engaging mechanism which changes a state of the first cover and the second cover between an engaged state and a non-engaged state.

A method of manufacturing a pattern includes providing a pattern of a first liquid on a medium, applying a powder material to the provided pattern, and providing a second liquid to the powder material applied to the first liquid.

The present invention provides a method of multi-pass inkjet printing comprising: (i) providing an inkjet ink comprising a radiation-curable monomer and a photoinitiator; (ii) jetting the ink via a printhead on to a substrate, wherein the ink is applied in multiple passes of the printhead with respect to the substrate, with each pass jetting a portion of ink in a layer on the substrate, with a first layer being jetted directly on to the substrate and subsequent layers being jetted onto the preceding layer, to build an image formed of the multiple layers; and (iii) exposing all of the layers of ink to actinic radiation to cure the ink, wherein the order of jetting the layers and curing is that pairs of layers are applied to the substrate without exposing the first layer of the pair to actinic radiation prior to the second layer of the pair of layers being applied, curing the pair of layers simultaneously by exposing the pair of layers to actinic radiation, and repeating until the image is formed.

Test patterns are printed by ink jet means for jetting ink containing a color material and transparent liquid jet means for jetting transparent liquid. In the test patterns, ink and transparent liquid are applied to different regions on the same medium and ink application regions and transparent liquid application regions are arranged adjacent to each other. A device for determining the amount of transparent liquid to be jetted includes information acquisition means for acquiring information representing the amount of medium deformation of a medium on which the test patterns are printed, and information processing means for determining the amount of transparent liquid to be jetted by the transparent liquid jet means for jetting the transparent liquid, from the information representing the amount of medium deformation acquired by the information acquisition means.

Certain examples of apparatus for applying fluid in a printing system are described. The apparatus comprise a first chamber having a first aperture extending along a first axis, and a second chamber having a second aperture extending along a second axis, wherein the first axis is substantially parallel to the second axis. The second chamber is movable with respect to the first chamber. Also, methods for supplying a fluid, and printing systems are described.

A droplet discharging apparatus (10) includes a supporting section (20) including a supporting surface (21) that supports a medium M, a first head (81) including a first nozzle that discharges first liquid onto the medium supported by the supporting surface (21), a second head (82) including a second nozzle that discharges second liquid that promotes curing of the first liquid by reacting with the first liquid onto the medium M supported by the supporting surface (21), a carriage (83) that reciprocally travels in a width direction while holding the first head (81) and the second head (82), an air sending section (70) that generates airflow in the front direction in an discharging area facing the supporting surface, and a shielding section (85) that shields the airflow in the front direction in the discharging area R1.

In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.
