Abstract: A printing control device determines whether a first printing mode in which a pretreatment liquid that reacts with a liquid jetted from an ink jet head to relatively increase a viscosity of a liquid is applied to a medium or a second printing mode in which the pretreatment liquid is not applied to the medium is set; sets a first driving waveform as a driving waveform of the ink jet head in a case of the first printing mode, and sets a second driving waveform as the driving waveform of the ink jet head in a case of the second printing mode is set; and reduces a maximum liquid jetting amount to be jetted from one nozzle in one jetting period in a case where the second driving waveform is applied as compared with a case where the first driving waveform is applied.

Abstract: Provided are an ink jet recording device and a method of manufacturing a drying cylinder, which suppress drying unevenness while suppressing slippage of a recording medium. The ink jet recording device includes: an ink jet head that applies an ink to a recording surface of a recording medium to form an image; and a drying cylinder that heats the recording medium by bringing the recording surface of the recording medium to which the ink is applied into contact with an outer peripheral surface of the drying cylinder, in which the outer peripheral surface of the drying cylinder has a maximum static friction coefficient of 0.54 or less and an arithmetic average roughness of 1.6 μm or more, and a solvent amount of the ink on the recording surface that comes into contact with the outer peripheral surface of the drying cylinder is 200 μg/cm2 or less.

Abstract: A medium processing device that suppresses adhesion of a liquid, with improved durability of a member that comes into contact with a medium after a drying treatment. The medium processing device includes: a drying device that performs the drying treatment on a medium; and a contact member that first comes into contact with a liquid adhering surface of the medium, after the drying treatment. The drying device performs the drying treatment so that a mass of a liquid per unit area on a liquid adhering surface of the medium is 200 μg/cm2 or less. The contact member has a cooling structure. Bonding work of a contact surface that comes into contact with the liquid adhering surface with respect to a liquid applied region of the liquid adhering surface is 80 mN/m or less. Vickers hardness of the contact surface is 450 Hv or more and 600 Hv or less.

Abstract: Provided are a conveyance device and a printing device that suppress drying unevenness of a recording medium to be conveyed in a state where liquid is applied thereonto. The drying unevenness is suppressed by a conveyance device including: a holding member that holds a recording medium having a first surface onto which liquid is applied; a guide member having a guide surface that comes into contact with a second surface that is a surface opposite to the first surface of the recording medium; and a drive mechanism that drives the holding member and the guide member in a conveyance direction, in which the guide surface has either or both of hole portions and projection portions, and a diameter of the hole portion and the projection portion, or a diameter of an inscribed circle inscribed in the hole portion and the projection portion is 0.31 mm or less.
