摘要： When a black image region is printed, the overall pixels in the region is printed by a black ink. Then, a cation type cyan ink which makes a coloring agent in the ink insoluble is printed on the pixels of a predetermined pattern. By this, the dye of the black ink is maintained near the surface of the printing medium to increase density of the black image. At the same time, for preventing variation of tone of the black image, the pixels of the predetermined pattern are printed by a yellow ink.
摘要翻译：当打印黑色图像区域时，通过黑色墨水印刷该区域中的整体像素。然后，将使不溶于油墨的着色剂的阳离子型青色墨水印刷在预定图案的像素上。由此，黑色油墨的染料保持在打印介质的表面附近，以增加黑色图像的浓度。同时，为了防止黑色图像的色调变化，通过黄色墨水印刷预定图案的像素。

摘要： A method of a cleaning of an ejection face by supplying a head liquid on the face of an inkjet head provided with ink ejection openings and then by performing a wiping operation. Sufficient cleaning is achieved by appropriately specifying relative relationships among the surface tensions of the face, the ink and the head liquid, and by efficiently and surely removing an ink residue from the face. By supplying the head liquid to the ink residue on the face, both are mixed with each other, and thereby the ink residue is incorporated into the head liquid. In this respect, by using the ink and the head liquid both having a surface tension higher than that of the face, a wetting of a dissolved matter of the ink residue with respect to the face is reduced, and the dissolved matter of the ink residue is smoothly moved by the wiping operation.

摘要： In a method of cleaning an ejection face by supplying a head liquid on a surface (ejection face) of an inkjet head provided with ink ejection outlets, and then by performing wiping operations thereon, an ink residue on the ejection face is efficiently and surely removed from the ejection face to achieve a sufficient cleaning thereon. For this purpose, a first wiping operation is first performed such that a wiper (9A) is relatively largely bent, and slidingly contacts the ejection face at an abdomen thereof to efficiently perform the application, stirring and mixing of the head liquid. Then, a second wiping operation is performed such that an edge portion of the top end of a wiper (9B) slidingly contacts the surface to efficiently scrape the mixture of the head liquid and the ink residue.
