Control apparatus for controlling process for printing

In a control apparatus, first type binary image data representing density of pixels arranged along a first image direction at a first resolution is acquired, and a first determining process is executed to determine an exposure pattern used to execute exposures of exposure lines at a second resolution lower than the first resolution along a first exposure direction. In the first determining process, a partial exposure pattern for exposing an output partial area that is correlated with a binary partial area and that overlaps N successive exposure lines is determined such that distribution of exposure amounts in the output partial area along the first exposure direction differs according to layout of second-value pixels in the binary partial area at least in the first image direction, thereby enabling an image of color material to be formed through development at a resolution higher than the second resolution in the first exposure direction.
