A printing method for printing a printing medium whose printed side will be laminated after being printed. The printing method includes a non-white ink application step of applying an aqueous non-white ink composition containing a non-white coloring material onto the printing medium, a white ink application step of applying an aqueous white ink composition containing a white coloring material onto the non-white ink composition on the printing medium, and a clear ink application step of applying a clear ink composition containing a resin onto the white ink composition on the printing medium.

A conveyance control device includes a processor and a memory. The processor is configured to control a conveyor. The conveyor is configured to convey a platen from a conveyance start position of the platen to one of a plurality of printers via a pretreatment device. The pretreatment device is configured to perform pretreatment on a recording medium placed on the platen. The conveyor is configured to convey the platen to one of a first lane including a first printer group formed of a plurality of the printers or a second lane including a second printer group formed of a plurality of the printers. The memory stores computer-readable instructions that instruct the processor to perform determination processing of determining whether to convey the platen to the first lane or to convey the platen to the second lane, based on the recording medium placed on the platen.

A rotation device rotates a sheet on an upstream side of, in a sheet conveyance orientation, a working device positioned in a middle of a conveyance path, thereby changing an orientation of the sheet. An information acquiring portion acquires sheet size information and sheet orientation information representing a size and the orientation of the sheet in a sheet storing portion, and working position information representing a working position on the sheet. A rotation control portion controls the rotation device in accordance with the sheet orientation information and the working position information. The working control portion controls the working device in accordance with the orientation of the sheet after passing through the rotation device, and the sheet size information and the working position information.

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.
