【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、複数の吐出口から記録液の小滴を被記録面
上へ噴射して情報の記録を行うシリアルタイプの液体噴
射記録法に関する。The present invention relates to a serial type liquid jet recording method for recording information by ejecting recording liquid droplets onto a recording surface from a plurality of ejection ports. .
〔従来の技術〕 従来、記録液（インク等）の小滴を飛翔させて被記録

吐出口を有する液体噴射記録ヘッドを用いたシリアルタ
イプの液体噴射記録法が一般に知られている。[Prior Art] Conventionally, a liquid jet recording head having a plurality of ejection ports for ejecting small droplets of a recording liquid (ink or the like) to record information such as characters or images on a recording material (paper or the like) is used. The serial type liquid jet recording method has been generally known.
第５図はこのような従来の記録法による記録装置の記
録部の概略構成例を示す。ここで、501は被記録材、502

タイミングベルトまたはワイヤである。FIG. 5 shows an example of a schematic configuration of a recording unit of a recording apparatus according to such a conventional recording method. Here, 501 is a recording material, 502
Is a recording head, 504 is an ink tank for supplying a recording liquid, 506 is a platen for feeding a recording material, 508 is a signal cable for driving signal transmission, 509 is a pulley, 510 is a timing belt or wire for moving the recording head. .
このような液体噴射記録法では情報を被記録材501上
に記録するために、記録ヘッド502を水平方向にを複数
回ずらせて走査させることにより、記録ヘッド幅の帯状
の記録512を被記録材501上に繰返し、所望の面積の記録
を得ていた。In such a liquid jet recording method, in order to record information on the recording material 501, the recording head 502 is horizontally shifted a plurality of times to scan, so that a belt-shaped recording 512 having a recording head width is recorded. Repeated on the 501 to get the desired area record.
しかしながら上述したような構成の従来の液体噴射記
録法では帯状の記録512と次の帯状の記録512との接合部
513に不連続部が生じて、その接合部513がすじ状に見え
る場合があった。However, in the conventional liquid jet recording method having the above-mentioned configuration, the joint between the band-shaped recording 512 and the next band-shaped recording 512 is formed.
In some cases, a discontinuous portion was generated in 513 and the joint portion 513 looked like a streak.
このすじ状に見える原因には複数の要素があり、しか
も全ての要素をまだ全部は把握できていないが、主な原
因の１つに帯状記録512と帯状記録512の不連続部513に
おける液滴のにじみ方が、それ以外の例えば帯状記録51
2の中央部のにじみ方と異なることであるということが
分かってきた。There are multiple factors that cause the appearance of streaks, and all of the factors have not yet been grasped, but one of the main causes is the swath record 512 and the droplets at the discontinuity 513 of the swath record 512. The other way of bleeding is, for example, band recording 51
It has become clear that this is different from the bleeding in the center of 2.
すなわち、帯状記録512の端部ではにじむ面積が大き
く、次の帯状の記録512が前の帯状記録512の大きくにじ
んだ部分の上に重ねて記録されることとなるので、帯状
記録の画素と次の帯状記録の画素の間隔を一定になるよ
うに、紙送りを精度良く行なっても結果的に接合部513
が濃い記録となってしまうという不具合が生じた。In other words, the bleeding area is large at the end of the band-shaped recording 512, and the next band-shaped recording 512 is recorded over the largely-blurred portion of the previous band-shaped recording 512. Even if the paper is fed accurately so that the intervals between pixels in the strip-shaped recording are constant, as a result,
There was a problem that the recording was dark.
以上の事を第６図の図面を用いて更に説明すると、記

となり、すじ状に見えることとなる。この現象は特に複
数の色を重ねて記録する場合にそ発生割合が著しい。To further explain the above with reference to the drawing of FIG. 6, a band-shaped record 201 is recorded on the recording material 501 by the droplets 205 ejected from the recording head 502. At this time, the bleeding 202 at the end of the band is wider than the bleeding at the center of the band. The edge of the next strip-shaped recording is recorded on this bleed 202 and becomes a dark recording, which looks like a stripe. The occurrence rate of this phenomenon is particularly remarkable when a plurality of colors are overlaid and recorded.
本発明の目的は、上述の欠点を除去し、すじ模様の発
生しない入力情報に忠実な記録が得られる液体噴射記録
法を提供することにある。An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a liquid jet recording method capable of obtaining recording faithful to input information without generation of streak patterns.

とを特徴とする。In order to achieve such an object, the present invention is a serial type liquid jet recording method in which a plurality of small droplets of a recording liquid are ejected in parallel and ejected onto a recording surface to repeat a belt-shaped information recording. By ejecting a transparent droplet onto a recording surface area wider than the width, the liquid amount per unit area of the end portion of the belt-shaped recording is made substantially the same as the liquid amount per unit area of the belt-shaped central portion, The feature is that the bleeding amount of the recording droplets is made uniform.

Since wide bleeding peculiar to the part is prevented, it is possible to obtain faithful recording to the input information with no streak pattern.
