Abstract: A measuring device and measuring method are provided for testing the cut quality of a sheet. The measuring device is provided with a transparent scanning substrate for holding the sheet, a scanning device with a scanning window, and a cover for covering the sheet held by the scanning substrate, wherein the scanning window overlaps the sheet, forming edge regions, and the cover has different reflection properties from the sheet for producing a high-contrast scanned image of the sheet and of the edge regions between the sheet and the scanning window. The measuring method includes positioning the sheet on a transparent scanning substrate, covering the sheet with a cover, and scanning the sheet with a scanning device, wherein the scanning device scans in the region of a scanning window which encompasses both the sheet and edge regions surrounding the sheet, and differences in contrast between the sheet and the edge regions are detected.

Abstract: The present invention concerns a measuring device for testing the cut quality of a sheet as well as a measuring method for testing the cut quality of a sheet, with which the cut quality can be tested reliably by the fact that the measuring device is provided with a transparent scanning substrate 3 comprising a stop 1 for a sheet for holding the sheet 4, a scanning device 15 with a scanning window 14 and a cover 21 for covering the sheet 4 held by the scanning substrate 3, wherein the scanning window 14 overlaps the sheet 4, forming edge surfaces 10, 11, 12, 13, and the cover 21 has different reflection properties from the sheet 4 for producing a high-contrast scanned image of the sheet 4 and of the edge surfaces 10, 11, 12, 13 between the sheet 4 and the scanning window 14, or by the fact that with the measuring method the sheet 4 is positioned on a transparent scanning substrate 3 with a stop 1, covered with a cover 21 and scanned with a scanning device 15, wherein the scanning device 15 scans in the region
