ABSTRACT:
A registration system (10) maintains registration of colors printed on a lenticular material (M) by a printing press (P) to form an image (I). A predetermined pattern (12) is printed on the material together with the image. A camera (36) obtains an image of each printed pattern as the lenticular material moves from one end of the press to the other, a strobe (40) and an image magnifier (34) also being used for this purpose. A monitor (32) displays the image for an observer to determine if the printed colors are properly registering with each other. A controller (46) for adjusting the position of print rollers (R) is operable by the observer to adjust the rollers, as necessary, for an observed printed color determined to be not properly registering with the other printed colors to be brought into registry therewith. A baseline pattern (14) is printed as are bars (28) for each printed color. By monitoring the relative position of the bars to the baseline pattern, the alignment of each color is readily determined and appropriate adjustments made, if necessary.
