DIGITALLY ASSISTED COMPENSATION OF MISALIGNMENTS IN DIE CUTTING OF CARDBOARD

A system and a method for compensating misalignments of a die for cutting cardboard of a die cutter. The system comprises a processor configured to detect height-correcting elements in an image of a correction template for the die, and further configured to produce a digital file comprising a digital representation of detected height-correcting elements; and an optical device for projecting images configured to project the digital representation of the digital file on a pressure compensation plate of the die cutter. The method comprises digitally detecting height-correcting elements in an image of a correction template for the die; producing a digital representation of detected height-correcting elements; and projecting the digital representation on a pressure compensation plate of the die cutter.
