Question 7:
I heard that your systems features a function that is called PixelRegistration. What is this exactly?
Answer to question 7:
All Vision Inspection systems claim that they can find very small defects. They can detect small splashes, streaks, etc. All these defects have in common that they are very isolated and can be detected easily.
The situation changes dramatically when it comes to inspection of fine text. How can the system detect partially broken characters or missing i-dots? Usually inspection systems face big problems when trying to detect such defects in text areas. Web stretch effects and printing deficiencies cause many false defects and make the operator set the inspection tolerances so low that the system will most likely not find anymore any significant defects.
This is where PixelRegistration kicks in: The intelligent algorithm adjusts the image from the camera at a pixel level thus compensating for stretch and printing effects. As a result, the inspection tolerances can be set to small values and the system will find small defects like broken characters. How small? This obviously also depends on the camera resolution as explained in question 6. But at a given camera resolution PixelRegistration will make you get the maximum out of the system.
