    • In a transfer type ink jet recording system, a scanning is conducted on a transfer drum using a recording head to form ink dot strings. The recording head is moved in one subscanning direction with a fixed pitch so that ink drops are impacted to positions which are not adjacent to ink dot strings formed immediately before the current scanning step, whereby a repellent phenomenon is prevented from occurring. According to another aspect of the invention, the printing sequence is changed in accordance with the density of print data. A dot counter counts the number of printing dots of each of a plurality of writing blocks in a video memory. A controller decides the sequence of printing the printing blocks on the basis of the result, and transfers information indicative of the sequence of the printing blocks to a memory selector. In deciding the sequence, restriction is set so that adjacent blocks are not successively subjected to the printing step. The memory selector reads out printing data from a video memory on the basis of the sequence information, and transfers the data to a recording head.
    • 在转印式喷墨记录系统中,使用记录头在转印鼓上进行扫描以形成墨点串。 记录头在一个副扫描方向上以固定间距移动,使得墨滴撞击到与当前扫描步骤之前形成的墨点串不相邻的位置,从而防止发生排斥现象。 根据本发明的另一方面,打印顺序根据打印数据的密度而改变。 点计数器对视频存储器中的多个写入块中的每一个的打印点的数量进行计数。 控制器根据结果确定打印块的顺序,并且将指示打印块序列的信息传送到存储选择器。 在确定顺序时,限制被设定为使相邻的块不是连续地进行打印步骤。 存储器选择器基于序列信息从视频存储器读出打印数据,并将数据传送到记录头。
