摘要:
A method of creating a fluid layer in the micrometer range includes transferring a fluid between substrates and forming a fluid layer. A surface energy of a first substrate releasing the fluid is higher than a surface energy of a fluid on the first substrate to create a first fluid deposit on the first substrate. A surface energy of a second substrate accepting the fluid is lower than a surface energy of a fluid on the second substrate to create a second fluid deposit on the second substrate that is reduced as compared to the first fluid deposit. A surface energy of a third substrate accepting the fluid is higher than a surface energy of a fluid on the third substrate to create a substantially homogeneous third fluid deposit on the third substrate that forms the fluid layer.

An apparatus for film transfer includes at least one printing press and at least one transfer film supply roller, a transfer film guiding device for guiding the transfer film web from the transfer film supply roller to a transfer nip. In order to ensure a variable film transfer in different printing units of the printing press, up to now the transfer film supply roller is moved with a film module into the region of the desired printing unit. In order to make a variable film transfer possible without complicated moving, the guiding device has web guiding elements at least in the region of the at least one printing press and the web guiding elements are enabled to selectively guide the transfer film web to different positions on the at least one printing press.

摘要:
A printing machine contains a transfer unit for transferring a transfer layer onto a print carrier in a transfer nip. The printing machine further has at least one applicator unit for applying an adhesive to the print carrier. The applicator unit precedes the transfer unit, and the transfer layer is detached from the carrier film in the transfer unit in the regions in which adhesive is applied. By printing units being converted into transfer units or applicator units, the functionality of the printing unit for a printing operation is lost. If the applicator device and the transfer device are located in this order on an impression cylinder of a printing unit, the applied adhesive is not predried sufficiently. To overcome these disadvantages, the transfer unit is a further processing unit and has at least one further processing device which follows the transfer nip and which acts on the print carrier.

摘要:
A method for creating a structured surface or a safety or decorative feature based thereon in a process of the printing industry wherein a liquid, preferably ink or varnish, and particles, preferably pearlescent pigments or a material having a similar effect are applied to a substrate. The liquid is provided with a surface structure and is characterized by a creation of a random surface structure, in particular a structure of mountains and valleys, of the liquid and by the creation of a random particle distribution, preferably a random particle orientation, by blowing a gas such as air onto the unhardened liquid which may be heated if desired. The surface that is thus created has a unique structure that is discernible by the human eye or detectable by camera and may, for instance, have a light/dark change.
摘要:
A sheet-fed offset printing press prints multiple colors on both sides of sheets, preferably on sheets of paper. A first row of in-line printing units print a first side of the sheet, before the sheets are turned in a reversing device, which is followed by a second row of in-line printing units for printing the other side of the sheets. The second row of in-line printing units is followed by one or more varnishing units that are arranged in such a way or include varnishing blanket cylinders that are arranged in such a way that the front sides and the back sides of the passing sheets are varnished.

摘要:
A method for applying an anti-corrosion protective layer to the surface of a cylinder for the printing unit of a printing press, the surface having been cleaned and microroughened, includes uniformly applying to the cylinder surface a thermally cross-linkable plastic material dissolved in a solvent, drying and, respectively curing and cross-linking the plastic material layer at an elevated temperature, and then mounting the cylinder in the printing unit without further processing the surface form; and a printing unit cylinder having a surface to which the anti-corrosion layer has been applied.
