The invention relates to a device for applying adhesive tape (40) to the cylindrical surface (21) of a cylindrical body (20), said device comprising: at least two axially parallel securing rolls (30a, 30b) designed to make contact with the cylindrical surface of the cylindrical body; an adhesive tape feed for feeding the adhesive tape (40) to the cylindrical body (20); and means for rotating the cylindrical body (20) about its cylindrical axis.

The Interchangeable/Modular Textile Printing Pod system marks a significant innovation in screen printing, merging manual techniques with textile enhancement in a singular, efficient design. It features a linear, expandable layout of printing Pods that optimize workspace by aligning along the perimeter, freeing central areas for broader use. Each Pod, equipped with versatile stations, connects via a Rail & Trolley mechanism, supporting seamless movement of heating attachments like Flash Heaters and Heat Presses across Pods. This design not only conserves space but also enhances workflow, enabling swift transitions across printing tasks. Ideal for space-constrained environments, this adaptable and scalable system offers a modern solution to diverse screen printing needs, embodying efficiency and flexibility in printmaking technology.

Examples disclosed herein relate to front-to-back registration of a printed content onto a print medium. In one example, a trigger signal generated by a sensor upon detection of a trigger mark on a first surface of a print medium is received. The trigger mark includes a leading edge and a trailing edge, wherein the leading edge and the trailing edge are non-parallel. Based on the trigger signal, a distance of the trailing edge from a point on the leading edge is determined. Once determined, a measure of lateral wander of the print medium with respect to the print path is obtained. The measure of the lateral wander is determined by comparing the distance between the leading edge and the trailing edge, with a threshold value.

An apparatus (1) for preparing a flexographic printing sleeve (3) comprises a support structure (21), comprising first support mechanism (2) which defines a workstation for rotatably supporting a first flexographic printing sleeve (3) such that it can rotate about a preset axis (K-K), a roll (11) of double-sided adhesive tape rotatably supported by a second support mechanism (10), and a first feeding and guiding mechanism (13) for unwinding the double-sided adhesive tape (12) from the roll (11) and directing the double-sided adhesive tape (12) to the surface of the first sleeve (3).

A sheet-fed printing press includes a printing cylinder and a high-precision sensor system for monitoring a sheet run in the area of the printing cylinder. At least one gage, which is mounted on the printing cylinder, can be detected by the sensor system. It is particularly advantageous if the sensor system is configured to be self-calibrating. A method for calibrating a sensor system and a method for aligning a sensor system are also provided.

A graphic arts support assembly is operable to be used with a graphic arts plate assembly in a press. The graphic arts support assembly and the plate assembly are configured for removable association with a lift mechanism including a shiftable lift element. The support assembly includes a graphic arts magnetic support structure operable to removably support the graphic arts plate assembly. The magnetic support structure includes a support plate, a magnet fixed relative to the plate, and an alignment element projecting from the support plate. The support assembly is operable to be mounted on the lift mechanism so that the lift element is aligned with a lift opening of the support plate, with the lift element shiftable through the lift opening to locate at least part of the graphic arts plate assembly away from the support plate.

Disclosed is a correction system for an alignment film printing plate, including: a roller and a printing plate mounted as a sleeve outside of the roller, wherein a first end portion of the printing plate is provided thereon with a plurality of columns of buckle groups, and a second end portion of the printing plate is provided thereon with a plurality of columns of slot groups engaged with the buckle groups. The correction system for the alignment film printing plate further includes an image controller used for measuring a deviation value between an actual position and a preset position for printing of an alignment film on a substrate. The correcting system of the alignment film printing plate has a simple structure and is capable of realizing different stretching degrees of an alignment film pattern at different positions on the printing plate, so as to improve a correction effect of the printing plate. As a result, deviation can be reduced between an actual position and a preset position for printing of the alignment film on the substrate, without significant increase in costs.

An applicator for transferring an indicia to a substrate includes an ink layer forming the indicia. A white layer is disposed on the ink layer. An adhesive layer is disposed on the white layer. The adhesive layer is configured to adhere the ink layer and the white layer to the substrate.

A printing plate (10) having at least one optical marker (12, 14) for detecting a position of the printing plate (10) is described. The optical marker (12, 14) comprises an optically detectable structure (18) being positioned within a periphery (20) of the marker (12, 14). Furthermore, a method for detecting a position of a printing plate (10) is presented. Additionally, a control unit (38) for a system (36) for detecting a position of a printing plate (10) and a system (36) for detecting a position of a printing plate (10) are explained. Moreover, a computer program comprising computer readable program code means for causing steps of the method is defined.

A method of screen printing a design on a substrate, the method comprises the steps of controlling a computer-controlled plotter to cut an outline of the design into stencil material the stencil including a perimeter. Then, registering the perimeter of the cut stencil with marks on a printing screen and securing the cut stencil to the printing screen. Then, positioning the printing screen and cut stencil on the substrate and applying ink through the printing screen and stencil onto the substrate, wherein the design is reproduced on the substrate.
