Abstract
A printing device includes an inline inspection system using one or more sensors to determine defects on a printed sheet. The control unit, or other component connected to the printing device, determines a plurality of horizontal and vertical portions within one or more images on the sheet that are above a colorant value, or CMYK, threshold. A set of the plurality of horizontal and vertical portions are identified from the images on the sheet. The set of horizontal portions may differ from the set of vertical portions. The printed images of these portions are captured by the inline sensor. The captured data is analyzed to determine a defect within the printed sheet.
Claims20
A method for performing an inline inspection during printing operations, the method comprising:
- receiving a printed sheet of a paper media within a printing device;
- determining a plurality of horizontal portions above a colorant value threshold on the printed sheet, wherein the horizontal portions extend in a horizontal direction across the printed sheet;
- identifying a set of the plurality of horizontal portions, wherein the set of horizontal portions span a width of the printed sheet;
- and
- analyzing the set of horizontal portions to detect a defect within the printed sheet.
An inspection system for a printing device, the inspection system configured to
- receive a printed sheet of a paper media within a printing device;
- determine a plurality of horizontal portions above a colorant value threshold on the printed sheet, wherein the horizontal portions extend in a horizontal direction across the printed sheet;
- identify a set of the plurality of horizontal portions, wherein the set of horizontal portions span a width of the printed sheet;
- determine a plurality of vertical portions above the colorant value threshold on the printed sheet, wherein the vertical portions extend in a vertical direction across the printed sheet;
- identify a set of the plurality of vertical portions, wherein the set of vertical portions span a length of the printed sheet;
- and
- analyze the set of horizontal portions and the set of vertical portions to detect a defect within the printed sheet.
