ABSTRACT:
A system and method in which a size of a pixel used to print lenticular depth images is changed to remove overlap in the slow scan print direction. A space adjustment of the space between scan lines can also be performed to remove pixel overlap. The pixel can also be elongated in the fast scan direction reducing fast scan resolution. An elongated pixel can be combined with skip space adjustment to remove pixel overlap. Printing the image lines in the fast scan or dot movement direction improves image quality. The print resolution in the fast scan direction can be reduced by increasing the printing rate compared to the data rate of the supplied image data, thereby cloning pixels in the fast scan direction, while maintaining a normal slow scan speed to normally print lines. Combinations of the above approaches to directional printing, removing slow scan pixel overlap and reducing file size can be accomplished.
