Image processing apparatus, image processing method, and computer program product for determining a direction of transparent color material pattern based on acquired grain direction

摘要

An image processing apparatus includes: a protected area determining unit that determines a protected area to be protected by forming a transparent color material pattern made of a transparent color material on recording paper; a grain-direction acquiring unit that acquires a grain direction of the recording paper; a pattern determining unit that determines a direction of the transparent color material pattern based on the acquired grain direction; a pattern generating unit that generates the transparent color material pattern in the determined direction; and a color material forming unit that forms the transparent color material pattern in the determined direction on the protected area of the recording paper.
