Previous attempts to aim single ink jet streams were inaccurate due to visual perception problems and guess work. The black ink stream is so small as to be almost invisible especially against a dark background. Seeing where the stream landed in a black pocket or gutter was at best guess work even with good lighting. Attempting to aim, even with back lighting and white background, often results in error.
