A method for printing a plurality of scan lines with one or more inkjet heads includes receiving at least one scanline; creating, from pixels of said at least one scanline, a plurality of bundles of a predetermined size comprising first bundles and consecutive bundles, said first and consecutive bundles comprising pixels for which nozzles of the one or more inkjet heads have to be fired within a first time period and within a consecutive time period, respectively; and storing said plurality of bundles in a first memory. The method includes transferring said plurality of bundles from first memory to second memory; and repeating until all said pixels are available in the second memory as the first bundles. Nozzles of the one or more inkjet heads are fired in accordance with the first bundles within the first time period and steps repeated for consecutive bundles and associated respective consecutive time periods.

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.

An inkjet recording apparatus includes a conveying portion, a recording portion including a line head including a plurality of recording heads, a temperature detecting portion, a cooling mechanism, and a control portion. The cooling mechanism includes a storing portion that stores cooling liquid, a circulation path of the cooling liquid that is arranged to be branched into a plurality of branch paths passing near the recording heads, a heat dissipating portion that dissipates heat of the cooling liquid, and a pump that causes the cooling liquid to circulate. If there exists, among the recording heads, a recording head that is predicted to undergo a temperature rise, the control portion increases a flow amount or circulation time of the cooling liquid in whichever of the branch paths serves as a flow path of the cooling liquid flowing toward the recording head that is predicted to undergo a temperature rise.

There is provided a liquid ejecting head including: first and second nozzle rows extending in a first direction; a first supply flow path; a first filter chamber having a first inlet; and a second filter chamber having a second inlet, in which the first and second nozzle rows are shifted from each other in both the first direction and a second direction orthogonal to the first direction, the first supply flow path has a branch flow path for distributing the liquid between the first filter chamber and the second filter chamber at a branch position, the branch position is disposed between the first filter chamber and the second filter chamber in a plan view, and the first and second inlets are disposed at a part where the first filter chamber and the second filter chamber overlap each other when viewed in the second direction.

A marker transport system and a method of operating the marker transport system. A group of print bars is located with respect to a marker transport platen and a marker transport belt. A vacuum source and a pneumatic solenoid block are associated with the marker transport platen. The marker transport platen includes airflow sections divided into process-direction slots and cross-section direction slots. The cross-section direction slots are located beneath the print bars and are connected to the vacuum source via the pneumatic solenoid block, which facilitates an individual control of each of the cross-process direction slots. Pneumatic valves are associated with the pneumatic solenoid block, which supplies a flow of vacuum to the cross-process direction vacuum slots. The pneumatic vales can be timed to allow the vacuum to be present when a sheet is present over a corresponding vacuum slot among the process-direction slots and the cross-section direction slots.
