Abstract: A printing apparatus includes a transport unit, a printing unit, a drying unit, and a control unit. The drying unit includes a contact heating unit with a contact heating surface configured to contact a back surface of a medium and an airflow ejecting unit with an airflow ejecting port. The control unit performs first control and second control. In the first control, the airflow ejecting unit is controlled such that an airflow is a first velocity. In the second control, an airflow velocity is slower than the first velocity. While the printing apparatus being in operation, the control unit performs the first control when a stopping period is less than a predetermined period, and performs the second control when the stopping period is equal to or more than the predetermined period, the stopping period being a period in which transporting the medium is at rest.

Abstract: The invention includes an aggregating agent coating section configured and arranged to apply an aggregating agent in a form of a powder to a recording medium and an ink discharge section configured and arranged to discharge an ink that is aggregated by the aggregating agent onto the recording medium to which the aggregating agent is applied. According to this configuration, applying the aggregating agent in the form of a powder the recording medium makes it possible to apply the aggregating agent to the recording medium without having to apply a treatment liquid that contains the aggregating agent to the recording medium. As such, the need for a step for drying a recording medium, which has been performed in instances where a treatment liquid was applied to the recording medium, is obviated.

Abstract: A printing apparatus executes a continuous printing by a printing execution unit while transporting a belt-shaped printing base material by a transport path in a longer direction. The printing execution unit includes a reaction solution discharge head, an ink discharge head, and a head for overprinting. The reaction solution discharge head forms a reaction solution layer containing a flocculant on a printing face of the printing base material. The ink discharge head forms a printing image by discharging an ink containing a color material on the reaction solution layer. The head for overprinting forms an overprint layer so as to be positioned on the reaction solution layer.

Abstract: There is provided a recording apparatus in which it is possible to use a suitable reaction liquid to be applied on the recording medium, out of multiple types of reaction liquids. A recording apparatus includes a transport mechanism that transports a recording medium, a reaction liquid applying mechanism that selectively applies, on the recording medium, either a first reaction liquid that reacts with ink or a second reaction liquid that reacts with the ink and is different from the first reaction liquid, and an ink discharge mechanism that is positioned downstream from the reaction liquid applying mechanism in the transport direction of the recording medium and discharges the ink onto the recording medium. It is preferable that the reaction liquid applying mechanism include a first reaction liquid discharge unit that discharges the first reaction liquid and a second reaction liquid discharge unit that discharges the second reaction liquid.

Abstract: A drying unit includes a housing and a first contact heating unit. The first contact heating unit is provided inside the housing. The first contact heating unit includes a first contact heating surface configured to come into contact with a back surface of a medium after printing. The first contact heating unit can change posture from first posture to second posture, in a state where a first engagement portion engages with a first guide portion of a first support portion and a second engagement portion engages with a second guide portion of a second support portion, by a movement from a first position where the first contact heating surface faces the back surface of the medium after printing to a second position where the first contact heating surface is more separated from the back surface of the medium after printing as compared to the first position.
