  • Method for defect detection in a printing system and printing system
    Patent number: 9465563
    Abstract: 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).
    Type: Grant
