Printing on sheet fibrous material
First Claim
1. A printing plant for printing a sheet fibrous material, said printing plant comprising:
- at least one conveyor belt exhibiting an exposed surface configured to receive the sheet fibrous material, the exposed surface defining an operative tract configured to temporarily receive in contact a first side of the sheet fibrous material and to guide the sheet fibrous material along an advancement direction,at least one printing station configured to ink-print at least part of a second side of the sheet fibrous material opposite the first side, said printing station operating at the conveyor belt and being configured to print the sheet fibrous material placed on the operative tract of the conveyor belt, andat least one preparing station disposed upstream of the printing station with respect to the advancement direction of the sheet fibrous material, said preparing station being configured to modify a surface hydrophobicity of at least part of the sheet fibrous material,wherein the preparing station comprises at least one plasma treater configured to produce a treatment environment in which at least one portion of the fibrous material is received and in which an ionized gas is present, and the preparing station is configured to deposit, on the sheet fibrous material, a treatment composition comprising a treatment foam.

Abstract
A plant and process for printing a sheet fibrous material. The printing plant includes a conveyor belt, a printing station, and a preparing station. The conveyor belt is configured for receiving the sheet fibrous material and guiding along an advancement direction. The printing station is adapted to ink-print at least part of a second side of the sheet fibrous material. The preparing station is configured for modifying the surface hydrophobicity of at least part of the sheet fibrous material. The preparing station includes a plasma treating device configured to define a treatment environment where a portion of the fibrous material is received. The control unit is configured for commanding the movement of the conveyor belt and controlling at least an operative parameter of the plasma treating device as a function of the movement of the conveyor belt.

16. A process of digitally printing a sheet fibrous material, comprising the following steps:
-
moving the sheet fibrous material along an advancement direction, placing a first side of the sheet fibrous material in contact with an exposed surface of a conveyor belt defining an operative tract of the conveyor belt in which the conveyor belt supports the fibrous material, and ink-printing a second side opposite the first side of the sheet fibrous material that is in contact with the conveyor belt, wherein said process further comprises, before the ink-printing step, at least one step of modifying the surface hydrophobicity of at least one portion of the sheet fibrous material, the modifying step comprising; plasma treating said at least one portion of the sheet fibrous material and applying a treatment composition comprising a treatment foam on said at least one portion of the sheet fibrous material. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
