Documents containing high-resolution images, diagrams, and characters are created and distributed even in general offices due to the widespread use of high-performance PCs, digital cameras, and image software and the setup of network environments.
Fuji Xerox has addressed high-quality technology for a more faithful print out of such documents.

As shown in Fig. 1, conventional processing (600 dpi) makes jagged edges of diagonal lines at low angles noticeable while such diagonal lines can be reproduced smoothly by use of new image enhancement processing technology capitalizing on the output characteristics of high resolution (2,400 dpi).

This image enhancement processing technology has realized the design of a new mapping scheme which responds to 2,400 dpi on a more minutely meshed matrix from conventional 600-dpi technology. In addition, processing is performed in the secondary scanning direction as well as in the primary scanning direction. As a result, this allows minute pixel control, enabling smoother reproduction of black lines and character outlines. This new feature is especially effective in reproducing diagonal lines at low angles which have been difficult to achieve in the pasts.
