Abstract

System, method, article for determining registration and/or skew errors in a print medium with respect to a printing element includes a print medium including a two-dimensional pattern including a grid within a geometric shape. The grid has a plurality of vertical and horizontal lines, the intersection of each forming a cross-hair defining an X-Y positional data point; the collection of data points defining a data set. The geometric shape is in the form of a two-dimensional target having a plurality of concentric rings; an innermost one enclosing at least one of the X-Y positional data points in the data set. The printing element provides a marker onto the print medium. The positional location of the marker with respect to the one of the at least one enclosed X-Y positional data point defines a directional displacement vector for correcting registration and/or skew error between the print medium and the printing element.
