CR33 - CR34
Colour register control system for packaging rotogravure presses
T EC H N I C A L F E AT U R E S
The CR33 - CR34 register control system reduces waste in all production phases:
start-ups, ramp-ups, reel-changes both on electrical and mechanical shaft presses.
Advanced electronic technologies and dedicated software algorithms guarantee
register stability for the entire production cycle.
Single optic fibre scanning head
Double optic fibre scanning head
Various mark lay downs and shapes can be programmed or selected from our data
base, so that existing cylinder libraries can be used.
The optic fibre scanning heads utilize high sensitivity RGB sensors and they automatically select the colours, allowing the detection of very light colours on any kind
of substrate.
Automatic mark recognition, mark auto search and mark auto centering, are
performed by motorized optics that allow for a fully automatic start-up without
operator intervention within a positioning error of ± 7 mm.
When the register error exceeds the set threshold value an alarm and a waste command
are provided.
The auto-preset function, developed for electrical shaft presses, performs the cylinder
phase presetting and guarantees register start-ups completely in automatic.
Speed range from 7 to 1.500 m/min.
Circumferential max. correction range ± 8 mm.
Error sensitivity 0,01 mm.
The LED light source guarantees more than 100.000 hours of life (11 years). The 1 mm wide
light spot allows mark size to be reduced to 3 mm.
The database for the job storage includes all the job parameter settings, such as press
configuration, compensator preset, register tolerance, etc.
Real time charts display the error trend and the production statistics. The system also
provides an interface to a network or external users for data sharing.
The system is configured for remote support through a dedicated VPN connection.

GRAFIKSCAN 2200
Print inspection and press control
T EC H N I C A L F E AT U R E S
GRAFIKSCAN 2200 is a system that ensures print quality control and minimizes
substrate consumption during start-ups and production. Immediate identification
of defects minimizes waste and guarantees the quality of production.
Dedicated software and algorithms allow excellent image reproduction. The implementation of specific features and tools provides the operator with a help to allow
the operator to achieve high quality production.
3CCD digital video camera has a resolution of 1.392 x 1.040 pixels (4,3 Megapixels)
with field of view of 240 x 180 mm and is mounted on a motorized and presettable
traverse. Optics with 16X magnification has a motorized and presettable zoom,
focus and iris.
The lighting by white LED ensures a quality and a distribution of light which is free
from image degradation even on metalized substrates. The life of this components
is practically unlimited.
The entire print repeat is continuously inspected with resolution and speed set out by
the operator.
It is possible to store up to 30 positions with different magnification, iris and focus
settings to allow the operator to inspect critical areas in the image.
“SPLIT IMAGE” function allows the real time print image to be compared with the
stored master on a single screen.
The Quick-Zoom function allows instantaneous detail magnification with the single
push of a button.
The GRAFIKSCAN 2200 capabilities can be augmented by additional software and
features (interactive register©, bar code verification, Δ colour monitoring) to increase
the control of printing.
The GRAFIKSCAN 2200 can be integrated with the 100% inspection system GRAFIKSCAN
3000.
The system is configured for remote support through a dedicated VPN connection.

GRAFIKSCAN 3000
100% Inspection system
T EC H N I C A L F E AT U R E S
GRAFIKSCAN 3000 is a system for the 100% inspection of the printed web, guaranteeing total control during the printing process by automatically surveying and
cataloguing all defects in order to provide a real-time analysis of the progress of
production up to 600 m/min.
GRAFIKSCAN 3000, having a modular architecture, can be integrated with the
GRAFIKSCAN 2200. The combination of the different technologies linked to imageprocessing algorithms provides a complete and simple instrument for operator
support to control any printing process: gravure, flexographic and offset.
The system is composed of one or more linear colour cameras, designed to perform at
production speeds exceeding 600 m/min while maintaining perfect image resolution.
The white LED lighting ensures a quality and a distribution of light without any
image degradation even on metalized substrates. The life of this component is over
100.000 hours (11 years).
The GRAFIKSCAN 3000 capabilities can be augmented by additional software and
features (interactive register©, bar code verification, Δ colour monitoring) to
increase the control of printing.
The system is configured for remote support through a dedicated VPN connection.
“DEFECT CONTROL”
Defects are instantly highlighted on the screen with relevant cataloguing according to
the following types: register, streaking, colour variation, spots and hazing.
Each class of defect can be assigned a separate alarm threshold. A visual and/or
acoustic alarm warns the operator when the threshold has been exceeded and the
screen displays the detected defect. By simply pressing a button the sample image
can be superimposed to the defect image for an easy comparison. A dedicated algorithm compensates for web shift and stretch.
“WIDE SCREEN”
Real-time display of the entire print repeat on 30” super HD monitors. The display of
each complete repeat enables the operator to instantly analyse the print conditions
of the entire web and adjust for any problems (skew, differences in pressure, etc.).
“CLICK & VIEW”
This function combines the 30” wide screen and the area camera with traverse and
motorized zoom. Detailed analysis of any part of the repeat can be instantly viewed on
the 19” operator interface by clicking the cursor in the desired location on the full
repeat display. This interface ensures accurate viewing of the desired field of view.

OPTIONAL SOFTWARE GRAFIKSCAN
The tools for the better print monitoring
Interactive Register (Click & Drag©)
It is an innovative function that allows to the operator, using the TOUCH SCREEN
interface, to interact directly with the image in order to control the register motors.
Thanks to this innovation, the systems GRAFIKSCAN 2200 and GRAFIKSCAN 3000 can
set precise register even with the press stopped.
Press&Go
The software allows drastic reduction of waste at the start-up in CI flexo presses. The
function, reading some special reference marks and by means of powerful software
algorithms specially designed, is able to adjust the printing pressures and the colour
register in a very short time, so ensuring a huge waste reduction.
Barcode Monitoring
Δ Colour Monitoring
Statistical Defect Detection
The GRAFIKSCAN 2200 system is able to detect all typical print defects which are
sorted by category. The operator can individually adjust the sensitivity of defect
thresholds to ensure the maximum quality control.
Barcode Monitoring
This software verifies the BARCODES in-line, ensuring rapid intervention by the operator when any of the barcode specifications are out of standard tolerances.
Colour Monitoring
This function allows to the user to compare the stored standard CIEL*a*b* values with
values acquired in real time. The comparison is made continuously throughout the
duration of the production, ensuring operator intervention before reaching nonacceptable levels that could compromise the image.
Quality Report
The software generates a report containing all the information relevant to the production (defects, press stops, reel splices,…). The collected information can be visualized in
statistic diagram both for jobs and rolls.
Click & Drag© Function
Statistical Defect Detection
Waste Management
By reading the reports generated by the defects control systems, a special software
stops the slitter rewinder accordingly.
