An image-forming device includes a printing portion (40) that forms images on the media being transported using ink, a varnish application portion (60) that applies aqueous varnish to the media on which the images are formed, a treatment portion (50, 70) that performs a treatment on the media so that a stickiness evaluation value which is a stickiness evaluation value indicating a degree of stickiness of the aqueous varnish applied to the media when the media to which the aqueous varnish is applied are output from the varnish application portion and is derived using a damped vibration percentage of a pendulum caused to do pendulum motions from an arbitrary location of the media to which the aqueous varnish is applied as a pivot reaches 0.24 or less, and an accumulation portion (80) that accumulates the media to which the aqueous varnish is applied and on which the treatment is performed.

The invention relates to a process for the surface treatment of a security document which comprises, at least on one of its opposite faces, at least one security printing consisting of at least one pattern, this face and this at least one associated printing being covered with a transparent protective coating, in which a varnish comprising crystalline nanocellulose in a portion of 0.5% to 10% by weight of the varnish is put in place via the printing or coating technique on said at least one face, and in which said varnish layer is dried.

[Problems] To provide printed seamless cans in small lots having many kinds of designs, the printed seamless cans excellently reproducing the density of the area solidly printed all over the surface and forming vivid images. [Means for Solution] A printed seamless can forming at least a printed layer and a finishing varnish layer on at least the body portion on the outer surface of the seamless can, the printed layer having an image formed by the plate-type printing and an image formed by the ink-jet printing, and being covered with the finishing varnish layer.

Ein crfindungsgcmäßcs Verfahren zum gerasterten Aufbringen von Fluidcn auf Substrate, ist ein Verfahren, wobei im Fall i) eines wenigstens in einem Abschnitt (3) ungerasterten Substrats (1) oder einer wenigstens in dem Abschnitt (3) ungerasterten Beschichtung (2) des Substrats (1) ein gerastertes erstes Bild (5ʹ) eines ersten Fluids (5) auf das Substrat (1) in dem Abschnitt (3) aufgebracht wird oder im Fall ii) eines wenigstens in dem Abschnitt (3) gerasterten Substrats (1) oder einer wenigstens in dem Abschnitt (3) gerasterten Beschichtung (2) des Substrats (1) ein verschieden gerastertes erstes Bild (5') eines ersten Fluids (5) auf das Substrat (1) in dem Abschnitt (3) aufgebracht wird (in beiden Fällen vorzugsweise mit einer Offsetdruckform), ein ungerastertes, das erste Bild (5') überdeckendes zweites Bild (6') eines zweiten Fluids (6) (vorzugsweise eines transparenten Lacks) auf das Substrat (1) in dem Abschnitt (3) aufgebracht wird (vorzugsweise mit einer Flexodruckform), und die Formation (8) des zweiten Fluids (6) auf dem Substrat (1) in dem Abschnitt (3) im Wesentlichen durch das Raster des ersten Bilds (5') in dem Abschnitt (3) bestimmt wird. Besonders bevorzugt weist das erste Bild (5') eine Anisotropie, z.B. aufgrund der Verwendung eines Linienrasters, und dadurch das zweite Bild (6') einen richtungsabhängigen Glanz auf. Weiter bevorzugt wird das Substrat (1) zunächst mit Druckfarbe (2) oder Kaltfolientransfermaterial (2) beschichtet. Auf diese Weise können mit bekannten drucktechnischen Mitteln Effekte erzielt werden, die jenen von Hologrammen oder strukturierten (gebürsteten, polierten) Metalloberflächen ähnlich, jedoch sehr viel günstiger und inline herstellbar sind.
摘要:
There is described a sheet-fed or web-fed printing press for numbering and varnishing of security documents, especially banknotes, including : - a numbering group (02) comprising at least one numbering unit (21, 22) for numbering printed material in the form of individual sheets or successive portions of a continuous web carrying multiple security imprints ; and - a varnishing group (03) located downstream of the numbering group (02) for applying varnish onto recto and verso sides of the printed material, the varnishing group (03) comprising at least a first varnishing unit (31) disposed above a path of the printed material to apply varnish on the recto side of the printed material and at least a second varnishing unit (32) disposed below the path of the printed material to apply varnish on the verso side of the printed material.
摘要:
There is described a method for varnishing security documents, especially intaglio-printed security documents such as banknotes, wherein both sides of the security documents are covered by a protective varnish. The method comprises the step of applying a thicker layer of protective varnish on a side of the security documents which exhibits a greater surface roughness, especially the side which is opposite to the side of the security documents which was last printed by intaglio printing. Also described in a varnishing machine for carrying out the above method.
摘要:
A method of offset printing wherein a layer of varnish or similar coating material is deposited onto a print drum and an ink image pattern layer is printed upon the varnish layer using a technique such as inkjet printing; the print drum transfers the ink layer onto a print substrate with a portion of the varnish layer thereupon, thus acting as a covering layer for the printed image.
