    • A transfer type ink jet printer having an ink jet head for ejecting droplets of ink in which charged coloring particles have been dispersed in a solvent in the form of insulating carrier liquid having a low dielectric constant, a transfer medium for carrying and moving an ink image formed of ink droplets ejected from the head, and a pressure roller for transferring the ink image written to the transfer medium to a recording medium. By temporarily fixing the charged coloring particles in the ink image onto the transfer medium until the ink image is led to the transfer means after the ink image is formed on the transfer medium, good and high-speed image printing has been made possible without vapor generation, so that an excellent image free from any printing pattern is available at a low transfer pressure. There is also provided a unit for removing a solvent by making the solvent on the transfer medium with the charged coloring particles temporarily fixed by the means for temporarily fixing the particles contact water or a surface active aqueous liquid agent.
    • 一种转印型喷墨打印机,具有用于喷射墨滴的喷墨头,其中带电着色颗粒已经分散在具有低介电常数的绝缘载体液体形式的溶剂中,用于承载和移动墨图像的转印介质 由从头部喷出的墨滴形成;以及加压辊,用于将写入转印介质的油墨图像转印到记录介质上。 通过将墨水图像中的带电着色颗粒临时固定到转印介质上,直到在转印介质上形成油墨图像之后将油墨图像引导到转印装置上,才能实现良好的高速图像印刷 ,使得在低转印压力下可以获得没有任何印刷图案的优异图像。 还提供了通过在转印介质上制造溶剂,通过用于临时固定颗粒接触水的装置或表面活性含水液体试剂暂时固定带电着色颗粒来除去溶剂的单元。

    • 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。
