Inspections of prints

After a - possibly long lasting - learning phase, human experts can rate the quality of a complex product quite well. These ratings, however, often are subjective to a certain degree.

In order to implement a quality control software system, two goals have to be met: on the one hand, one wants to obtain an objective qulaity measure; one the other hand, one wants to retain a "human-like" quality rating.

Due to the "soft" nature of Fuzzy Logic, both aims can be reached by modelling the expert knowledge with a fuzzy system.
