发明名称 Ink-jet printing apparatus and ink reservoir unit
摘要 <p>An ink-jet head assembly (60) includes a plurality of ink-jet heads (61,62) that are fixed mutually. A first ink-jet head (61) has a plurality of deep cyan nozzles (CD) and a plurality of deep magenta nozzles (MD), whereas a second ink-jet head (62) has a plurality of light cyan nozzles (CL) and a plurality of light magenta nozzles (ML). The plurality of nozzles of the respective inks are positioned in such a manner that the plurality of nozzles of an identical color and an identical density are arrayed substantially along a sub-scanning direction and that neither the nozzles of different colors nor the nozzles of different densities are located on an identical straight line extending in the sub-scanning direction. The respective one nozzles of deep cyan ink, deep magenta ink, light cyan ink, and light magenta ink are positioned to be aligned in a straight line extending in a main scanning direction. Also, various ink reservoir combinations are disclosed, as is the use of the same actuator for the light colored inks and the use of a print head having a higher positional accuracy for the head with the lighter inks. &lt;IMAGE&gt;</p>
