Use of high brilliance white LED technology to guarantee the best reliable and durable (11 years) light source
The TechnologyThe Technology
Speed, accuracy and high reliability.
Assurance of full automatic make ready
Huge waste reduction.
Touch screen and Windows based graphic allows friendly use and minimal operator training.
PerformancesPerformances
Circumferential and Lateral Micro-mark Register Control
LED source lights with min. 100.000 hours life time.
Cameras mounted on motorized bars, optics, electronic boards and light sources are designed by Grafikontrol
Electronic boards with DSP (Digital Signal Processing) image processor.
Micro marks are geometric shapes and not dots, not subject to print conditions. They can be placed anywhere.
Image Acquisition: the high speed camera reaches up to 200 images/sec, allowing a reading at every cylinder revolution.

Longitudinal and Side-lay Ribbons Register Control
LED source lights with min. 100.000 hours life time
Register error correction up to ±100 mm for both longitudinal and side register
Full automatic start up for both cut-off and side-lay register without operator’s intervention
Side register is controlled with no printing (ribbon slitting edge)
No mark loss, nor variations on longitudinal register when correction is made on the side register due to continuous mark auto-centering
One single detecting head for both longitudinal and side register control
Cut-off register controlled through a small mark, placed in a 3,2 mm non printed gap

CLOSED LOOP COLOUR DENSITY CONTROL
Lighting with high brilliance white LED matrix (min 100.000 hours life time).
Closed loop control of both Colour Densities and Chromatic Balance.
Information about dot gain, print contrast, slur, trapping for each key, for best colour analysis.
Reading of two keys simultaneously (twice as fast as closest competitor system) and immediate correction of the density of the two sectors (not at the end of the web scanning).
User friendly.
High waste reduction at every make-ready of new jobs:
~1500 copy waste for a 48 pp press.

WEB DEFECTS
DETECTION
Continuous paper quality control from roll stand to press delivery.
Quick interpretation to distinguish paper breaks due to the web defect, roll prep or press issues.
PAPERSCAN:PAPERSCAN: 1 mm2 defects detection sensitivity for spots, patches, folds, dirt, holes, cuts, breaks, tears and edge-nicks.
PAPERSCAN:PAPERSCAN: Lighting system made of LED modules with lifetime higher than 100 000 hours.
BREAKSCAN:BREAKSCAN: Continuous high speed video recording of running web up to 1500m/min.
BREAKSCAN:BREAKSCAN: Sequence of events, causes of web breaks, can be analyzed frame by frame.
