How it works
How DualView Works
Two Fixed-Focus Cameras
A wide-angle camera sees 120 × 90 mm; a central telephoto camera sees 32 × 24 mm. As the operator zooms, the system switches cameras without a pause, down to a 4 × 3 mm field with digital zoom.
A diffuse area flash lights even metallic and reflective print evenly, and the image is synchronised to the repeat by print mark, gear sensor or encoder.
Why ELSCAN
See the Print, Fix It Sooner
Modular
Start with a manual OMS 4112 and add motorisation, image memory and colour comparison later.
Master Comparison
Compare the running print with a stored master image.
Colour Check
OMS 4115–4117 compare colour (Delta E, Lab) and can raise an alarm.
Front and Back
OMS 421_ double-camera systems check both sides and register.
