  • Method for calibrating printing of lenticular images to lenticular media
    Patent number: 7593132
    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.
