The perfect finishing solution for digital labels

The LC350 is a compact, economic and fully digital laser finishing machine. Simply download the file from pre-press department and the laser module is ready. The system can be fitted with an optional barcode reader for faster reload of existing jobs.

The laser is available in 175W, 250W and 350W versions and the label cutting power can be modulated depending on the final effect you want to achieve.

Characteristics

The GM LC350 is an excellent choice for digital label press. The basic configuration has laser die, slitting and dual rewind, and the Semi-Rotary Flexo varnish station is often added. Moreover, more complex setups are possible, such as spot varnish, lamination, cold foil, AutoKnives slitting with an automatic knife positioning system and more. The laser module comes on a standard GM frame and is designed to fit into any GM converting line, eg DC350Flex+, with minor electrical and mechanical modifications.

  • Quick delivery
    With near zero setup time for existing and new jobs, this system counters the challenges of smaller runs and shorter lead times, thus ensuring day-to-day delivery of labels. An investment in the LC350 will give you continuous production and increase efficiency and productivity.
  • Cost savings
    Save the cost of buying conventional die plates, and spare the time spent setting up a new job. The LC350 will increase the flexibility of your production facility to take on short runs and lead times and is almost certainly the most cost-efficient laser die cut solution.
  • Upgrade path
    The LC350 system can be upgraded up to 350W. The laser mirror system and control cards will remain in the unit - only the laser source is upgraded. This ensures a long lifetime of the machine and the full benefit of future low-cost high power lasers.


Other key features of LC350:

  • Superior laser cut quality thanks to the fully digital mirror (galvo) system.
  • Extra-long repeat lengths (up to 2.8 m) for special productions
  • Eliminated the "startup hole burn problem" of more simple systems thanks to digital & automatic 3D focus and power control system.
  • No tooling required, simply download the file from pre-press department and the GM LC350 laser will start working.
  • The laser has an optional bar code reader for quick change over and integration into Esko graphics pre-press solutions.
  • The laser module comes as a standard plug-in module for the GM converts, but can also be feed into any other rotary web-fed machine.
  • The system is built using 100% standard industry components from major laser suppliers.
  • No more ordering conventional tooling and waiting days for delivery.
  • No more long make-readies and waste material.
  • No more storage and capital tied up in conventional tooling.
  • No more lifting heavy rotary tools.
  • Online support and remote diagnostics.
  • Industry 4.0 ready.
