Publication number: 20200139701Abstract: A controller checks ink quantity to be ejected to a specific area on a first side (specific area ink quantity) and determines an ink quantity ratio. The specific area is a strip-shaped area including a side edge on upstream side in a conveying direction of a paper sheet on the first side. When the ink quantity ratio is larger than a reference ink quantity ratio, the controller performs a black conversion process on pixels in a conversion target range. The conversion target range is a range corresponding to the specific area in the image data of the first side. The black conversion process is a process of converting a pixel to which three color inks, i.e. cyan, magenta, and yellow inks are to be ejected into a pixel to which only black ink is to be ejected.Type: ApplicationFiled: October 30, 2019Publication date: May 7, 2020Applicant: KYOCERA Document Solutions Inc.Inventors: Toyotsune INOUE, Hiroatsu TAMAI, Takeshi WATANABE, Hiroyuki UEDA, Yasuhiro MICHISHITA, Naoto MIYAKOSHI, Yusuke TAKANO, Noriaki OZAWA
