Apparatus and method for locating a portion of a continuous web of material having graphics printed thereon at a correct location in a cutting and creasing machine for forming carton blanks by comparing the location of a section of the graphics on a portion of the continuous web with a preset location of where the section of graphics should be and generating a control signal for moving the portion in vector and parallel paths to the correct location in the cutting and creasing machine. The continuous web is moved by applying a force on opposite sides of the center line of the continuous web along a linear line wherein the linear lines are located so that the included angle between the linear lines in the direction of movement of the continuous web is less than 180 degrees. Also, the linear lines can be located so that the included angle between each linear line and the center line of the continuous web in the direction of movement of the continuous web is less than 90 degrees.
