Abstract
The embodiments herein relate to a method performed by a system (100) for handling variations in a mark (110) printed by a group (105) of industrial printers (101). The system (100) obtains images of the printed mark (110) printed by each of the printers (101) in the group (105). The system (100) creates a composite image from the obtained images. The printed marks (110) appear as a repeating pattern in the composite image. The system (100) compares the printed marks (110) in the composite image to each other or to another mark. The system (100) detects variations with a first resolution in the printed marks (110) in the composite image as a result of the comparison. The system (100) creates an augmented image in which the detected variations are augmented to a second resolution. The first resolution is lower than the second resolution.
