摘要： The present invention provides an apparatus (20) for defect detection in a printing system (1). The apparatus (20) comprises: a sensing unit (21) having at least one first sensor device (22) for sensing a surface geometry or topology of a sheet (S) to be printed as the sheet (S) travels on a transport path (P) of the printing system (1) and for generating data (I) representative of that surface geometry or topology; and a processor device (25) for processing the data (I) from the first sensor device (22) to detect and classify deformations (D) in the surface geometry or topology of the sheet (S) based on at least one predetermined criterion, wherein the at least one predetermined criterion is adjustable or variable to suit operating conditions in the printing system (1). Further, the invention provides a corresponding method of detecting defects in a printing system (1).

摘要： A printing system comprising an apparatus for defect detection in a printing system. The printing system comprises, an image forming device, a sensing unit for sensing a surface geometry of a sheet to be printed and for generating data representative of that surface geometry, a processor device for processing the data; and a controller for controlling further progress of the sheet along a transport path of the printing system in dependence upon the deformations in the surface geometry of the sheet detected and classified by the processor device. The operating conditions the sheet is exposed to at the sensing unit are similar to the operating conditions the sheet is exposed at the image forming.
