Ink jet recording apparatus

摘要

An ink jet recording apparatus has at least one ink chamber (15) having an orifice through which ink drops are ejected, each ink drop having a variable amount of ink and being ejected at a timing corresponding to the amount of ink; and a controller (3, 20) for causing said ink chamber to eject ink drops therefrom in accordance with print data. The ink drop has an amount of ink in accordance with the level of gradation of the print data and is ejected at a timing in accordance with the amount of ink. The ink chamber may includes a plurality of ink chambers (11B, 11Y, 11M, 11C). A black ink chamber (11B) is located at a first distance (L1) away from the print medium and ejects black ink drops along line K1. Color ink chambers (11Y, 11M, and 11C) are aligned in a plane parallel to the surface of the print medium (16) and oriented so that the color ink drops are ejected toward the print medium (16) along lines k1, k3, and k4, respectively. The color ink chambers eject ink aiming at a point (P1) at which the ink drops are merged before they reach the print medium (16). The point (P1) is located at a second distance (L2), which is shorter than the first distance (L1) away from the color ink chambers (11Y, 11M, 11C). <IMAGE>
