DC330 Finishing Solution
DC330 in standard configuration
General Description As digital label printing continues to grow, label-printing houses are realizing the need for all-inclusive digital printing systems which provide value-adding features for producing fully finished labels. The DC330 from Grafisk Maskinfabrik (GM) offers the ideal solution: a complete converting and finishing unit. The DC330 was created especially for use with digital printing presses. The DC330 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

Screen Printing Group, Flatbed
The SC330 screen printing unit
General Description The SC330 screen printing unit from Grafisk Maskinfabrik has a printing area of 330mm(width) x 304,8mm(length) and is designed and engineered to perform screen printing of the highest quality possible on flexible materials. After printing, the ink drying is undertaken by UV-curing(GEW). The SC330 is compatible with tooling (screens) from existing equipment. Preparing and setting up the SC330 is very simple and fast, which makes this machine suitable to complete even very short runs. Apart from being a costefficient alternative to rotary printing due to the low costs of mesh and frame, screen-printing also has several other advantages e.g. easy set-up and little waste. The unit is sold as a separate unit or part of the DC330 finishing line.
Technical specifications • Max. frame/mesh size: 460x500 mm. Print area 304.8x330mm • Speed 3-10m/min depending on job • Curing system: UV. • Servo register control • The printing unit can lift up for fast cleaning • Printing length adjustable by touch screen • Squeegee position adjustable both crosswise and in height by means of handles • The squeegee unit can lift up independently from the printing unit • Squeegee stroke adjustable by servo motor according to the printing length • Adjustable material output speed.

tems. The system is built using 100% standard industry components from major laser suppliers like Coherent. No tooling required, simply download the file from the Pre-press Department and the GM L330 laser will take off. The laser has an optional bar code reader for quick change over and integration into Esko Graphics’ pre-press solutions. The GM L330 laser comes as standard plug-in module for the GM converters, but can also be fed into any other rotary web feed machine, Please note that the laser works best in PP. PET and PAPER can be cut as well. PE and PVC are not supported. Thick substrate, e.g. for wine labels will cut slowly.

Inline Modules (buffers)
DC330 Mini inline with HP WS6600
General Description The DC330 finishing lines can as standard operate inline with a digital press. A 3-meter buffer is built in as standard in the lines. For high speed integration (operation over 20m/min) GM offers a wide range of buffers with a capacity from 10 to 48 meters. The buffer can store the web while the operator changes a roll on the finishing line. Thus, the press is never stopped doing production.
Technical specifications • Technical Specifications • Capacity: From 10 to 48 meters • Web width: 330 and 500mm • Speed: up to 50m/min inline operation • Tension control: Pneumatic with feedback (constant tension)
GM has more than 10 years of experience in inline operation with Xeikon, HP, Epson & Domino presses.

Web Video Inspection Module
Nikka web inspection module
General Description The DC330 finishing line comes with an interface for Nikka web inspection as standard. The system can stop the finishing in case of a fault/missing label/ misprint. Camera inspection is a valuable tool for quality control in the roll-to-roll production of labels and flexible packaging. When installed in a finishing line, the inspection system prevents defective material from reaching the end customer. The cameras on the printing press contribute to waste reduction and higher production speeds. Inspection systems also collect objective process information and supply data to production monitoring and system scheduling.
