When used in a multi-color printing environment, a register control ensures consistent print quality – and is also used in post-print applications for synchronizing cut, embossing, punching or coating processes using registers. To achieve this, special print marks are printed in addition to the actual printed image.

In conjunction with the register control integrated in SIMOTION, Siemens offers the SIMOTION TRC3000 wedge mark sensor for this purpose. It is the standard solution for the print domain, and is especially suitable for applications with very high requirements, including, for example, the reliable detection of low-contrast marks or of print marks on reflective materials.

As it is directly integrated into the motion control system of the printing machine, a register control is achieved that has a high level of performance and degree of reliability. It is favorably-priced and especially compact. Additional open-loop controls, operator panels or control cabinets are not required. Furthermore, it is not necessary to mount an additional encoder at the machine or printing cylinder.

The register control is made available through the SIMOTION Print Standard Add On TRC3000 application. Workshops are available for experienced SIMOTION users.

The modular SIMOTION TRC3000 wedge mark sensor comprises the RSH-PN evaluation unit with intelligent measured value processing (3-channel as RGB value) and specific accessories. It is directly connected to PROFINET IO with IRT via an integrated 2-port switch whereby it is integrated in the line topology of the real-time PROFINET network of the machine. In addition to the single-head version (1 fiber-optic cable), a 2-head version (2 fiber-optic cables) is also available. The 2-head version is used to address additional measurement tasks, such as reverse side measurement or parallel mark array arrangements. The fiber-optic cable is equipped with an optical system and is available in two lengths. For special measurement tasks, the optical power and measured value processing can be adjusted using a calibration box.
