Abstract:
The invention provides a method for determining parameters relevant to the print quality of a printed product. A macroscopic photogram of a measuring field of the printed product is recorded using a camera having a macro lens. An actual value of a parameter relevant to the print quality is determined from the macroscopic photogram. The actual value is compared to a nominal value of the parameter relevant to the print quality. Whether the measuring field is printed with adequate quality is determined based on the comparison of the actual valve with the nominal value of the parameter relevant to the print quality.
