Title (EN) INKJET RECORDING DEVICE AND INKJET RECORDING METHOD

(JA) インクジェット記録装置およびインクジェット記録方法
Abstract:
(EN) A smooth image excellent in uniformity is output by minimizing the occurrence of secondary color satellite and distributing as uniformly as possible the impact positions of satellites. For this purpose, recording is made such that the satellites of two kinds of ink (for example, cyan ink and magenta) to be recorded in the same pixel are allowed to impact separately on the opposite sides of a main dot recorded on the pixel. Accordingly, the arrangements of satellites are uniform and respective satellites are comparatively insignificant to thereby ensure the uniformity of an image.
(FR) Une image lissée d’excellente uniformité est fournie en minimisant l’occurrence de satellite couleur secondaire et distribuant aussi uniformément que possible les positions d’impact de satellites. Dans ce but, un enregistrement est réalisé de façon à ce que les satellites de deux types d’encre (par exemple l’encre cyan et magenta) à enregistrer dans le même pixel soient autorisés à s’appliquer séparément sur des côtés opposés d’un point principal enregistré dans le pixel. En accord, les dispositions de satellites sont uniformes et des satellites respectifs insignifiants pour ainsi assurer l’uniformité de l’image.
(JA)  2次色のサテライトの発生を極力抑制するとともに、サテライトの着弾位置をなるべく一様に分散させることにより、滑らかで一様性に優れた画像を出力する。そのために、同一画素に記録される2種類のインク(例えば、シアンインクとマゼンタ)のサテライトが、当該画素に記録されたメインドットの両側に別れて着弾されるように記録を行う。これにより、サテライトの配置が一様となり、個々のサテライトも比較的目立ちにくくなるため、画像の一様性が損なわれない。
