There is described a printing press (100***; 100****) adapted to carry out printing on a sheet-like or web-like substrate (S), in particular for the production of security documents such as banknotes, comprising a printing unit (2*; 2**; 2***; 2****) designed to print a first side (I) and/or a second side (II) of the substrate (S). The printing press (100***; 100****) further comprises an in-line casting device (80; 80*; 80**; 80***) adapted to apply a layer of material acting as an optical medium on a portion of a first side (I, II) of the substrate (S) and to replicate and form a micro-optical structure (L) in the layer of material acting as optical medium. The printing unit (2*; 2**; 2***; 2****) is furthermore adapted to print at least one printed pattern on the first or second side (I, II) of the substrate (S) in register with the micro-optical structure (L), wherein the printing unit (2*; 2**; 2***; 2****) comprises at least a first printing group (93) being adapted to print at least one printed pattern on the second side (II) of the substrate (S) in register with the micro-optical structure (L) and wherein the in-line casting device (80; 80*; 80**; 80***) comprises at least one embossing cylinder (85), which embossing cylinder (85) also is acting as counter-pressure cylinder and cooperates with a printing cylinder (8) of the at least first printing group (93) and/or whereas the in-line casting device (80; 80*; 80**; 80***) and the at least a first printing group (93) being arranged at the Substrate transport path such way, that in-line casting of the micro-optical structure, on one side of the sheets S, and printing of the associated pattern, on the other side of the sheets S, are performed in a same step, without this involving any sheet transfer operation.

A method of forming a digital print on a surface by applying powder of dry ink including colourants on the surface, bonding a part of the dry ink powder to the surface by a digital heating print head such that the digital print is formed by the bonded dry ink colourants and removing non-bonded dry ink from the surface.

A method of manufacturing a sanitised paper article 202 comprising the steps: supplying a paper sheet 12 having a first surface and a second surface to a flexographic printing apparatus 2 having a first sanitising module 10a, applying a sanitising solution to at least the first surface of the paper sheet 12 using the first sanitising module 10a, and forming an article from the sanitised paper sheet 12.

An image forming apparatus includes a conveyer that conveys a recording medium supporting an image; a softener that softens the image; and a powder applicator that applies powder to the surface of the softened image, in which the applied powder adheres to a range that is narrower in a width direction orthogonal to a conveyance direction of the recording medium conveyed by the conveyer than a maximum width of the image to be supported by the recording medium.

A method and equipment to form a digital print by applying dry colourants on a surface of a panel, bonding a part of the colourants with a binder and removing the non-bonded colourants from the surface. The method of forming a digital print on a surface of a panel includes displacing the panel under a digital drop application head, applying a liquid binder with the digital drop application head on the surface; applying colourants on the liquid binder and the surface; bonding a part of the colourants to the surface with the liquid binder; removing non-bonded colourants from the surface such that a digital print is formed by the bonded colourants; and applying heat and pressure on the panel, the surface and the bonded colorants such that the colourants are permanently bonded to the surface.

A method of forming a digital embossing on a surface by bonding hard press particles to a carrier. A liquid binder pattern is applied on the carrier by a digital drop application head. Hard press particles are applied on the carrier and the binder pattern such that some hard press particles are bonded to the carrier by the liquid pattern and non-bonded press particles are removed. The carrier with the bonded hard press particles is pressed to the surface and an embossing is formed when the carrier with the hard press particles is removed.

There is disclosed a print construction comprising: (a) a printing substrate having an image-receiving surface; (b) a receptive layer, at least partially covering said image-receiving surface, and having a particle reception surface distally disposed to said image-receiving surface, said receptive layer optionally having a thickness of at least 1000 nanometer (nm); and (c) a plurality of individual particles adhered to said particle reception surface, and forming a monolayer thereon, the features of which are described herein.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface (12) with a monolayer of particles, ii) treating the substrate surface (80) to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate (20), the donor surface (12) returns to the coating station (14) where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.
