A position fine tuning device for a unit-type die cutting & hot stamping machine includes at least two imprinting elements, wherein paper of the imprinting elements is delivered by the gripper installed on the chain. The present invention is characterized in that a positioning element is disposed on an input end of a first unit imprinting element and a positioning element is disposed on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. By providing the fine tuning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure; whereas, by setting up the reference positioning, it assures that the standards of the front and rear positioning are consistent.

A precision positioning device of a unit-type die cutting & hot stamping machine includes a positioning element on an input end of a first imprinting element and a positioning element on an output end of each imprinting element. Two neighboring positioning elements accomplish the positioning between the two positioning elements together. Each positioning element is constituted by a positioning assembly installed symmetrically on each end of the imprinting element. The positioning assembly includes a positioning rod which can rotate against an installation shaft. Each positioning rod includes a positioning block which is provided with a reference surface. A rear side of the gripper is provided with a reference matching surface. By the positioning elements, the accuracy in the art of die cutting & hot stamping can be assured when the machine is performing a multiple-working-position procedure.

A microfilter comprising a polymer layer formed from epoxy-based photo-definable dry film, and a plurality of apertures each extending through the polymer layer. A method of forming a microfilter is also disclosed. The method includes providing a first layer of epoxy-based photo-definable dry film disposed on a substrate, exposing the first layer to energy through a mask to form a pattern, defined by the mask, in the first layer of dry film, forming, from the exposed first layer of dry film, a polymer layer having a plurality of apertures extending therethrough, the plurality of apertures having a distribution defined by the pattern, and removing the polymer layer from the substrate.

A machine arrangement sequentially processes sheet-like substrates with multiple different processing stations each having a substrate-guiding unit and a substrate-processing unit. At least one of the processing stations has, as a substrate-processing unit, at least one non-impact printing device which prints on the substrate. The processing station with the at least one non-impact printing device has a printing cylinder. Each non-impact printing device is arranged at the circumference of the printing cylinder. The printing cylinder is triple-sized or quadruple-sized. A double-sized or a triple-sized transfer drum, or a corresponding feed cylinder, is arranged directly upstream of this printing cylinder. Alternatively, a double-sized or a triple-sized transfer drum, or a corresponding transfer cylinder, is arranged directly downstream of this printing cylinder.

A sheet-processing machine has a shaping device for processing sheets. The shaping device has at least one shaping point. The sheet-processing machine comprises at least one separating device. The at least one separating device is designed to remove at least one remaining piece from at least one sheet of the sheets. The at least one separating device is arranged downstream of the at least one shaping point along a transport path provided for transporting the sheets. At least one inspection device is arranged, downstream of the separating device in the transport direction of the sheets, to determine an actual state of the at least one sheet of the sheets. The invention additionally relates to a method for inspecting at least one remaining part of at least one sheet of sheets, which part has been processed by a shaping device, and to a method for inspecting at least one sheet of sheets.

In some examples, a print control strip includes at least one control patch configured as an element for color management. The element for color management may be configured to measure a color density and/or at least one spectral value and/or an area of coverage of individual printed printing colors. The print control strip further includes at least one control patch configured as a printing mark. The printing mark is configured for aligning a substrate in a transport direction and/or in a transverse direction. Additionally, the print control strip includes at least one control patch configured as a plate recognition patch. The plate recognition patch is configured to assign at least one printing color used to a printing plate and/or to an application mechanism and/or is configured for such assignment.

Apparatus (1) for changing a blade of a rotary die cutter, particularly for flexographic printing machines: a magnetic cylinder (3) configured to receive and support a die-cutting blade (5, 5′); a station (7) for inserting the blade (5, 5′) has a retention device (70) configured to retain the blade (5) in the insertion station; a guiding device (71) guides the blade (5, 5′) toward the magnetic cylinder (3); a station (9) for extracting the blade (5, 5′), has an extraction device (90) configured to remove the blade (5, 5′) from the magnetic cylinder (3).

A flexographic printer is provided with: a printing plate for transferring ink at an ink transfer site to an object to be printed S; an anilox roll for supplying ink to the printing plate at an ink supply site; a plate cylinder on which the printing plate is wound and rotated; and an ink solvent supply unit for supplying a solvent for the ink on the surface of the printing plate in a post-ink transfer region that is downstream of the ink transfer site in the plate cylinder rotation direction and upstream of the ink supply site in the plate cylinder rotation direction.

Methods, apparatuses and systems for printing an ink pattern on a moving web via die cutting are provided. A die roll including an inked pattern of die blades contacts a substrate to cut or cleave the substrate surface. While the die blades withdraw from the substrate, at least some of the ink transfers from the die blades to the cut substrate to form an ink pattern.

An image forming apparatus includes: an image former that prints a foil stamping image on a recording material in accordance with a job for printing the foil stamping image, the foil stamping image being a target to which foil is transferred in foil stamp printing; and a hardware processor that trims an image on a page identical to at least one page included in the job such that the image on the identical page does not overlap an image adjustment mark that is printed for adjusting an image to be overprinted, and causes the image former to print, together with the job, the identical page having the trimmed image.
