PADchecker

Print layout control – 100% quality assurance for your production

During the past three years, camera-supported cap control has paved its way into the factory floors of cap manufacturers. Many manufacturers automatically equip every new die-casting machine with this kind of testing system. Whoever wishes to deliver a perfect cap cannot, however, just stick to the shape test. Printing is also a significant feature of the product. Automatic print layout control is therefore the topic of the day. Who has the best technology for this testing? We maintain that the PADchecker® has assumed the leading technical position. Why? Because, in comparison to many pseudo colour systems, the familiar methods of histogram processing really do manage the colour. It also detects the smallest of print defects and printing plate offset, thanks to its unique true colour pattern matching not found on the global market until now. For the first time, the manufacturer's prerequisites can now be fulfilled – and that is really new. You can take advantage of this as well!


This is how the PADchecker® works:

  • The print layout is fed in by means of menu control. Depending on the testing parameters set, production-related print variations can also be entered (bold / narrow print, different colour levels) and accepted.
  • For the print layout check, first the position of the print layout is defined and then the current print layout is compared to the reference patterns.
  • The PADchecker® works with true colour processing and with revolutionary pattern matching techniques. Hence, the print offset can then also be checked when the moved prints do not merge with each other.
  • In addition, the smallest of print defects can be detected.
  • The simultaneously applied colour histogram method also enables fine colour changes to be checked.
  • Defective parts are traced precisely and a sort-out signal is triggered in due time.

The technical data in brief

Test criteria for plastic, aluminium and crown cork caps

  • Off-centre
decoration centralised
  • Lithography offset
"Pass fault"
  • Colour fluctuation
genuine colour check, not only grey values
  • Colour spots
also smears in the edge areas
  • External cap
incorrect decoration
  • Soiling
dirt in the granulate, burns
  • Smallest defects
down to the pixel size
  • Scratches
on visible surfaces
  • Rock testing
in crown corks
  • Adhesive compound
in crown corks

Integrated tracking and sorting function

  • Precise tracking from the camera to the sorting nozzle
  • No SPS required, most simple activation

High test reliability

  • Automatic detection of double caps (no distance)
  • There are no unchecked caps in the bulk packing container!
