    摘要： This ink jet recording apparatus makes it possible to reduce the requisite number of times that preliminary ejection is performed for the purpose of ejection recovery through suction, which must be effected to such a degree as to make color mixing on the recording paper sufficiently inconspicuous. With a plurality of recording heads using inks of different lightnesses, ejection recovery is performed successively on the recording heads in accordance with the descending order of ink lightness. In addition, the number of preliminary ejections after ejection recovery to be performed on the next recording head is also controlled, thereby attaining a still greater effect. In a method aspect, the present invention includes an initial discharge step for discharging ink from a recording head, interrupting the discharge of ink for an appropriate period set in accordance with the ink lightness, and discharging ink again from the discharge ports of the recording head after the interruption.

    摘要翻译： 该喷墨记录装置使得可以减少为了通过抽吸进行喷射恢复的目的而进行预喷射所需的次数，这必须达到使记录纸上的颜色混合足够不显眼的程度。 利用使用不同亮度的墨的多个记录头，根据墨水亮度的降序依次在记录头上执行喷射恢复。 此外，还可以控制在下一个记录头上执行喷射恢复之后的预喷射次数，从而获得更大的效果。 在方法方面，本发明包括一个用于从记录头排放墨水的初始放电步骤，中断根据墨水亮度设定的适当时间的墨水排出，并且再次从记录头的排出口排出墨水 中断后

    摘要： The present invention is designed to make uniform frequencies with which individual recording elements of a multihead are used in a recording apparatus for performing gray scale recording by controlling a number of dots recorded in a unit area. A gray scale pattern used to display gray scale is a pattern in which a plurality of blocks each comprising a dot concentration type gray scale pattern having a size smaller than that of the gray scale pattern is dispersed. The maximum difference between numbers of times the recording elements in the range of the gray scale pattern are used can be restricted within twice, and individual nozzles can be used uniformly. Consequently, imbalance of changes in the recording elements with time, caused by the differences between the frequencies with which the recording elements are used, can be restricted, thus restricting irregularities on an image.

    摘要翻译： 本发明被设计成使得在用于通过控制记录在单位区域中的点数进行灰度记录的记录装置中使用多头的各个记录元件的均匀频率。 用于显示灰度的灰度级图案是其中分散了大小小于灰度级图案的点浓度型灰度级图案的多个块的图案。 使用灰度图案范围内的记录元件的次数之间的最大差异可以限制在两次之内，并且可以均匀地使用各个喷嘴。 因此，可以限制由使用记录元件的频率之间的差异引起的记录元件随时间的变化的不平衡，从而限制图像上的不规则。

    摘要： An ink-jet printing process using an ink containing a dye having an ionicity. The process includes the steps of: providing a cloth containing (a) a substance having an ionicity opposite to the ionicity of the dye and a molecular weight of from 100 to 700, or a nonionic surfactant having a molecular weight of from 100 to 700 and an H.L.B. of from 7 to 15, and (b) a polymeric substance having an ionicity opposite to the ionicity of the dye and a molecular weight of from 2,000 to 200,000; printing on the cloth with the ink; washing the cloth after printing; and drying the cloth.
