METHOD AND USE OF A MANUALLY PORTABLE INSPECTION DEVICE FOR INSPECTING THE QUALITY OF RESULTS OF THE MECHANICAL PROCESSING OF A SHEET

The invention relates to a method for inspecting the quality of results of the mechanical processing of a sheet (3), preferably a paper, cardboard, paperboard, plastic or textile sheet, in a cutting, punching or embossing device by means of a manually portable inspection device (1), preferably a smartphone, a personal digital assistant (PDA) or a tablet computer, the inspection device (1) comprising: a camera apparatus (7) having at least one image sensor; a display apparatus (12); and an evaluation apparatus (13), wherein the inspection device (1) is manually positioned relative to a sheet, wherein at least one processed portion (10) of the sheet (3) is captured in an imaging manner by means of the camera apparatus and image data of the processed portion (10) are produced, and wherein at least one quality parameter (e.g. standard distance) of a processing result of the sheet (3) is determined from the produced image data by means of the evaluation apparatus (13) and is preferably displayed on the display apparatus (12).
