    • In a recording apparatus for recording on a recording medium by a plurality of recording heads, a scan unit has a carriage capable of mounting the recording heads at a predetermined interval and causes the recording heads to scan corresponding divided recording areas. A record control unit causes the recording heads to conduct a first record mode to record an area of a first recording width in a direction of scan by shared recording by the recording heads of the corresponding recording areas and a second record mode to record an area of a second recording width smaller than the recording width of the first recording width by causing at least one of the recording heads to record in the corresponding divided recording area when the corresponding divided recording areas are scanned. A distance between two recording apparatus mounted at outermost positions in the arrangement of the recording heads on the carriage is not larger than a difference between the first recording width and the second recording width.
    • 在用于通过多个记录头在记录介质上记录的记录装置中,扫描单元具有能够以预定间隔安装记录头的托架,并使记录头扫描相应的划分的记录区域。 记录控制单元使得记录头进行第一记录模式,以通过相应记录区域的记录头的共享记录来记录扫描方向上的第一记录宽度的区域和记录第二记录模式的区域 当扫描对应的划分的记录区域时,通过使至少一个记录头记录在对应的分割记录区域中,使第二记录宽度小于第一记录宽度的记录宽度。 安装在滑架上的记录头的布置中的最外侧位置的两个记录装置之间的距离不大于第一记录宽度和第二记录宽度之间的差。

    • Printing on a recording medium by lateral scans of a print head in accordance with print data. Content of print data is determined. Then, the print data is printed either with a first lateral scan process using a critical zone at edges in a lateral scan of the print head for printing, or with a second lateral scan process that does not use the critical zone for printing. The first or second lateral scan process is selected based on the print data. Preferably, the critical zone is sized in correspondence with ramp up non-uniformities of a print carriage on which the print head is mounted, so as to accommodate a distance between a point where print degradation due to speed non-uniformities are noticeable to a point where print degradation due to speed non-uniformities are no longer noticeable. The second lateral scan process preferably is a process in which a predetermined margin is inserted into the first lateral scan process. The second lateral scan process is used if print data for a current scan and print data for a previous scan, in at least the critical zone, are continuous print data, thereby alleviating ripple effects for the continuous data. In a case where the print data for the current scan and the print data for the previous scan are not continuous print data, the print data preferably is printed using the first lateral scan process.
    • 根据打印数据通过打印头的横向扫描在记录介质上进行打印。 确定打印数据的内容。 然后,使用在打印头的横向扫描中的边缘处的临界区域进行打印的第一横向扫描处理或者不使用用于打印的临界区域的第二横向扫描处理来打印打印数据。 基于打印数据选择第一或第二横向扫描处理。 优选地,临界区域的尺寸对应于其上安装有打印头的打印托架的斜度上升的不均匀性,以便适应由于速度非均匀性引起的打印劣化对点 由于速度不均匀性引起的打印劣化不再显着。 第二横向扫描处理优选地是将预定余量插入到第一横向扫描处理中的过程。 如果当前扫描的打印数据和至少在临界区域中的先前扫描的打印数据是连续打印数据,则可以使用第二横向扫描处理,从而减轻连续数据的纹理效应。 在当前扫描的打印数据和先前扫描的打印数据不是连续的打印数据的情况下,优选地使用第一横向扫描处理来打印打印数据。
