Knauf, a leading manufacturer of building materials and building systems, has recently started using image processing from IPF in several plants in order to check the quality of packaging markings without any gaps - with consistently positive results.
One of these plants is located in Lauterhofen, around 50 kilometers east of Nuremberg.
"We produce several thousand tons of lime-cement plaster every month. And every single bag of finished product is labeled on the two production lines for the base and finishing plaster," explains Josef Geitner, operations manager at the Lauterhofen plant. The labeling is done on the respective conveyor belts of the two production lines with a printer that applies the labeling to the packaging using inkjet heads. This amounts to around 1,500 bags per hour per production line.
