I obtained good matches if I used a program that
straightened each of the
partial scan images before assembly. No matter how carefully I aligned
the
page on the scanner, there were always small angular displacements from
image to image. Joining them together without postprocessing would show
the problem that you mention. But after straightening, they would join
virtually seamlessly (i.e., with a displacement, at 600 dpi, of a pixel or
two across the image height).
Try to use progrms for stitchin images, it is usually good enough,
straightens up the schematics and everything gets done easily.
