Abstract: A method for calibrating the printing of a lenticular image with respect to the lenticules of a lenticular sheet includes the step of printing a test pattern including a plurality of patches on a lenticular sheet with an ink jet printer. The patches are sensed though the lenticules with a sensing device and the sensed data is analyzed to determine a calibration factor that is used to subsequently print a lenticular image on the lenticular sheet. In a further embodiment, the method comprises aligning a lenticular sheet in the ink jet printer; sensing the lenticules on said lenticular sheet with the sensing device; analyzing the sensed data in the processing unit to determine the lenticule spacing; calculating a calibration factor based upon the analysis; and using the calibration factor to subsequently print a lenticular image.

Abstract: A method for calibrating the printing of a lenticular image with respect to the lenticules of a lenticular sheet includes the steps of printing a test pattern including a plurality of patches on a lenticular sheet with an ink jet printer. The patches are printed on a surface opposite the lenticules and each patch includes a series of line segments that extend in the same direction as the lenticules as aligned in the ink jet printer. The spacing of the line segments within each patch is varied in a known manner from patch to patch. The patches are sensed though the lenticules with a sensing device, and the sensed data is analyzed to determine which patch corresponds to sensed data that has the fewest light and dark bands. A calibration factor is calculated based on the analysis, and the calibration factor is used to subsequently print a lenticular image on the same or a second lenticular sheet of the same type.
