IDENTIFYING A LINEHEAD PRODUCING AN ARTIFACT IN CONTENT PRINTED ON A MOVING PRINT MEDIA |
摘要 |
A linehead that is producing an artifact in the content printed on a print media is identified by capturing an image of the content as the print media is moving to obtain pixel data and averaging the pixel data to produce blur in a direction the print media is moving. A determination is made as to whether the averaged pixel data is associated with content printed by a first linehead in a printing module. If the averaged pixel data is not associated with the the first linehead, the averaged pixel data from an image captured by a preceding linehead is subtracted from the averaged pixel data in the image to produce averaged pixel data that is associated with a single linehead. Derivative data of the averaged pixel data is then determined. A determination is made as to whether one or more peaks are present in the derivative data. |
