The printing plant (1) comprises: a station (14) for supplying a fibrous material configured for supplying the fibrous material along a predetermined operative path, a treating station (10) configured for treating the fibrous material with a treatment composition by applying the composition itself on a first side (T1) of the fibrous material (T); and a printing station (6) configured for ink-printing at least part of a second side (T2) of the fibrous material (T) opposite to the first side (T1). Moreover, the present invention refers to a process of printing a fibrous material.

A drying apparatus which dries a medium on which an image is formed with ink while conveying the medium includes a conveyance part, a heating part, a measurement part and a controller. The conveyance part conveys the medium in a predetermined conveyance direction. The heating part supplies energy to the image on the sheet conveyed in the conveyance part and dries the image. The measurement part measures a value accompanied with moisture contained in the medium. The controller estimates an amount of moisture contained in the medium based on the value measured by the measurement part, and controls at least one of the conveyance part and the heating part so as to change an amount of the energy supplied to the image based on the estimated amount of moisture.

A recording method is for performing recording by ejecting, onto a recording medium, ink and a reaction solution including a flocculating agent that flocculates a substance contained in the ink, and the recording method includes ejecting the reaction solution as a droplet onto the recording medium, and ejecting the ink as a droplet onto the recording medium. A relationship of Op1≥Op2 is satisfied when an ejection amount of the reaction solution during ejecting the reaction solution in a first recording mode is indicated with Op1, and an ejection amount of the reaction solution during ejecting the reaction solution in a second recording mode is indicated with Op2, the second recording mode having a recording speed lower than the first recording mode.

Microwave dryer of a print system with modulation of the microwave source using FSK. In one embodiment, a microwave dryer includes a microwave source coupled with a waveguide. The waveguide transports electromagnetic energy to dry wet colorant applied by a printer to print media. The microwave source provides the electromagnetic energy at an operating frequency. The microwave dryer also includes a processor coupled with an FSK modulator that modulates the operating frequency of the microwave source. The processor determines a modulating signal with a modulating frequency based on a period of time for the print media to traverse the waveguide, and applies binary values that represent the number of frequencies to an input of the FSK modulator to cause the FSK modulator to output the series of discrete frequencies over the period of time to vary intensity positions of the electromagnetic energy across the width of the print media.

In some examples, a first heating stage heats a print medium to a first temperature in a printing region when printing latex ink on the print medium, and a curing heating stage heats, in a curing zone, the print medium to a curing temperature greater than the first temperature to cure the latex ink on the print medium. A cooling stage located between the first and curing heating stages cools the print medium by directing a first part of airflow from the cooling stage to a printing zone, the cooling performed after the print medium has been heated by the first heating stage and prior to heating of the print medium by the curing heating stage. A second part of the airflow is directed from the cooling stage to the curing zone.

An image-forming device includes a printing portion that forms images on the media being transported using ink, a varnish application portion that applies aqueous varnish to the media on which the images are formed, a treatment portion that performs a treatment on the media so that a stickiness evaluation value which is a stickiness evaluation value indicating a degree of stickiness of the aqueous varnish applied to the media when the media to which the aqueous varnish is applied are output from the varnish application portion and is derived using a damped vibration percentage of a pendulum caused to do pendulum motions from an arbitrary location of the media to which the aqueous varnish is applied as a pivot reaches 0.24 or less, and an accumulation portion that accumulates the media to which the aqueous varnish is applied and on which the treatment is performed.
