摘要： Control of an ink ejection frequency to compensate for recording medium unevenness in printing by inducing a predetermined unevenness pattern into a recording medium, adjusting an ink ejection frequency of a print head based on the induced unevenness pattern, and controlling ink ejection based on the adjusted frequency. A plurality of print heads may be employed that may correspond to different color inks and may be controlled by a same control signal or individually. Control may also be varied for bi-directional printing based on a printing direction. The adjustment of the ink ejection frequency may be providing a predetermined recording unevenness pattern having periodic oscillations, dividing each periodic oscillation into a predetermined number of regions, setting a number of ink droplets to be ejected within each region, determining a gate array interval for each region, providing at least one parameter corresponding to a printing operation, and determining an ink ejection trigger difference for each ink droplet to be ejected within each region.
摘要翻译：控制喷墨频率以通过将预定的不均匀图案引入记录介质来补偿印刷中的记录介质不均匀性，基于感应的不均匀图案调节打印头的喷墨频率，并且基于调节的频率来控制喷墨。可以使用可以对应于不同颜色的墨水的多个打印头，并且可以由相同的控制信号或单独地控制。也可以根据打印方向对双向打印进行控制。喷墨频率的调节可以是提供具有周期性振荡的预定记录不均匀图案，将每个周期性振荡分成预定数量的区域，设定要在每个区域内喷射的墨滴数量，确定每个区域中的门阵列间隔区域，提供对应于打印操作的至少一个参数，以及确定每个区域内要喷射的每个墨滴的墨水喷射触发差。

摘要： An ink jet printing apparatus which performs printing by using a print head. The print head has at least a predetermined number of nozzles to eject ink. The apparatus includes a first prefiring mechanism for causing the print head to perform a prefiring operation to eject ink from nozzles of the print head for maintaining printing quality after a first time interval during a printing operation. The apparatus also includes a driving mechanism for driving nozzles of the print head based on data to be printed, and a second prefiring mechanism for causing the print head to perform the prefiring operation in a case where a number of the nozzles to be driven is changed. Preferably, the apparatus further includes a shifting mechanism for causing the driving mechanism to drive the nozzles of the print head based on the first time interval during the printing operation so as to enhance a power of ejecting ink and continue the printing operation after the first time interval without performing the prefiring operation. The shifting mechanism also preferably delays the prefiring operation to a second time interval longer than the first time interval, and after the second time interval, the first prefiring mechanism causes the print head to perform the prefiring operation. In a case where the number of nozzles to be driven is changed within a time duration after the first time interval and during the second time interval, the second prefiring mechanism causes the print head to perform the prefiring operation.

摘要： An apparatus includes a buffer to store n lines of data divided into areas of column units. The apparatus obtains information of a column position corresponding to an end of an image to be printed with respect to a scanning direction of a print head. The apparatus reads data from the areas of the column units including the column position information and reduces the data to generate reduced data. The apparatus compresses the reduced data by using a pattern having n lines of data to generate first compressed data. Then, the apparatus compresses the first compressed data by k-bit units to generate second compressed data.
