Recording device and recording method
A recording device including a feeding unit configured to feed out a target recording medium while supporting the target recording medium in a roll form, a head that ejects ink to a surface of the target recording medium fed from the feeding unit thereby forming an image on the surface, a corona irradiation unit that is arranged between the feeding unit and the head in a transport path of the target recording medium and modifies the surface by performing corona irradiation, and a transport path length changing unit that is arranged between the corona irradiation unit and the head and changes a length of the transport path.
INK JET PRINTER
A printer includes a platen to support a medium, a conveyor to convey the medium supported by the platen from an upstream side toward a downstream side in conveyance directions, a tension bar, and a floating bar. The tension bar is downstream of the platen in the conveyance directions and positioned such that a lower surface of the medium conveyed from the platen to the downstream side in the conveyance directions contacts the tension bar. The floating bar is downstream of the platen in the conveyance directions and upstream of the tension bar in the conveyance directions and positioned such that an upper surface of the medium located between the platen and the tension bar contacts the floating bar, and has a center axis freely movable by a predetermined degree.
Transport device, recording device, and medium transport method
A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.
Liquid ejection apparatus, winding control method, and computer readable recording medium
A liquid ejection apparatus includes a conveying unit, a winding unit, a printing unit, and a rotation control unit. The conveying unit is configured to intermittently convey a printing medium by a predetermined feed amount. The winding unit is configured to wind the printing medium conveyed by the conveying unit. The printing unit is configured to perform printing on the conveyed printing medium. The rotation control unit is configured to control the winding unit to rotate in a winding direction at a predetermined timing after the conveying unit has started to convey the printing medium intermittently, and then cause the winding unit to rotate in a reverse direction opposite to the winding direction.
Method of digital ink-jet printing a fabric including depositing a foam pretreatment
The present invention refers to a plant (1) for printing a fibrous material (T). 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.
WEB WINDING WITH FRICTION-BASED TENSIONING
A printing system includes a transport path for transporting a web medium. The transport path includes a slack region wherein the web medium is slack or substantially tension-free. A take-up roller is positioned at a downstream end of the transport path for receiving and winding the web medium. A tensioning device is positioned along the transport path between the slack region and the take-up roller. The tensioning device includes a first surface arranged for exerting a friction force on the web medium moving over the first surface in a direction opposite to a transport direction of the transport path, such that the web medium is tensioned between the tensioning device and the take-up roller. Since the friction force tensions the web being wound onto the take-up roller, the wound media rolls are tightly wound when applying “loose winding.”
METHOD FOR CONTROLLING A WEB IN A PRINTING APPARATUS
A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step. The ready-to-print mode includes the step of: operating the transport assembly to prevent a deformation of the print area of the web in the transport path, while maintaining the web in the ready-to-print mode. The web is maintained ready to print while preventing a deformation of the print area of the web in the transport path.
TRANSPORT DEVICE AND LIQUID EJECTING DEVICE
A transport device includes a roller unit having a first roller, a second roller, and a third roller among which a medium supplied from a holding unit holding the medium is wound, a transport unit configured to transport the medium passing through the roller unit, and a support portion movably supporting the roller unit with respect to the transport unit.
PRINTER CASSETTE WITH MOVABLE TENSIONING ROLLER AND ASSOCIATED PRINTER
An apparatus for holding label stock includes a body including a base and a roll holding area with a roll holding support extending from the base for receiving a roll of label stock. A plurality of rollers are located along a label stock feed path from the roll holding area to a label stock exit zone of the body. The plurality of rollers include a tensioning roller that is movable relative to the base to dissipate tension loads on label stock during label stock movement.
Printing apparatus
A printing apparatus including a set section on which a printing medium is set, a winding unit configured to wind, the printing medium transported from the set section, a head configured to discharge an ink onto an image forming surface of the printing medium being transported, thereby forming an image, and a drying chamber formed downstream of the head in a transport direction and downward of the head, the drying chamber being configured to dry the ink discharged to the printing medium, wherein the drying chamber is provided with an endless belt made of metal and configured to transport the printing medium while being in contact with an image non-forming surface on an opposite side of the printing medium from the image forming surface, and a plurality of rollers over which the endless belt is stretched, the plurality of rollers being configured to cause the endless belt to rotate.
