In various exemplary embodiments, a method for testing a valuable document () is provided, wherein: the valuable document () is illuminated line by line in such a way that a first group of lines () of the valuable document () is illuminated with light of a first wavelength and that at least one second group of lines () of the valuable document () is illuminated with light of a second wavelength, wherein at least partly lines () of the first group and lines () of the second group alternate, reflection light () that is reflected from the lines () and/or transmission light () that passes through the lines () are/is detected in a manner assigned to the lines () of the first group and the lines () of the second group, wherein first data are representative of the reflection light () and/or transmission light () assigned to the lines () of the first group and second data are representative of the reflection light () and/or transmission light () assigned to the lines () of the second group, the first data are processed in such a way that a first image () generated from the first data has a first resolution, and the second data are processed in such a way that a further image () generated from the second data has a second resolution, which is different from the first resolution, and the first image () is compared with a first reference image and the further image () is compared with a further reference image. 122.
