Method of controlling a printed object |
摘要 |
A method of controlling an object having a first and a second print executed at different stages, the method providing for acquiring an image of the object; calculating a relative deviation between the first print and the second print of the object; forming a virtual specimen image by superimposing a reference image of the first print and a reference image of the second print and taking into account the relative deviation; comparing the image with the specimen image; and emitting an error signal in the event the luminance values of the image fail to fall within an acceptance range of the luminance values of the specimen image, and the relative deviation is above a given value.
