FIELD: imaging.
SUBSTANCE: invention relates to a method for obtaining characteristics of the structure of a creped plate. The method includes providing an imaging system comprising one or more television or photographic sensors or devices, generating one or more signals defining one or more images of a creped plate structure zone, and evaluating the generated image of the creped plate structure by two-dimensional spectral analysis using one or more indicators to determine crepe ridge characteristics, crepe groove characteristics, embossed three-dimensional structure characteristics, plate swelling, plate internal tears, and/or loose fibre ends.
EFFECT: increasing the accuracy of detecting the characteristics of the structure of the creped plate.
