DC500 Wide Web Semi-rotary Finishing

The DC500 offers maximum flexibility with fast and easy job changes between 330mm and 500mm web. The DC500 converting line has one distinct feature that makes it special: It runs web widths ranging from 500mm down to 100mm. In addition to this, the modular set-up makes it easy to add sections like e.g. the hot foil. So when investing in a new line, instead of having to guess about future needs – just prepare for it with the DC500. As your print-jobs change, your finishing line should not have to. The DC500 gives you huge flexibility on web sizes. The DC500 is a long-term investment for your current and future needs.


As digital label printing continues to grow, label-printing houses are realising the need for all-inclusive digital printing systems that provide value-adding features for producing fully finished labels. The DC500 from Grafisk Maskinfabrik offers the ideal solution. A complete converting and finishing unit, this product was specially created for use with digital printing presses. The DC500 can be set up as an in-line extension to a digital label printing system, allowing the web to continue directly into the converter from the digital press. It can also be used as an off-line converting and finishing unit for jobs from other digital presses or conventional presses. It can even function as a printing press for specialized value-adding solutions.
