摘要： In a complimentary printing by bi-directional scanning of a head or by a plurality of heads, a plurality of patterns in which a print start timing is shifted by a predetermined amount are printed with respect to a reference dot, e.g. formed by the forward scan of the bi-directional scanning or by one of the plurality heads. In these patterns, an area factor by the dots formed by printing of the patterns is designed to be varied depending upon shifting amount. An average density is read from each of the plurality of patterns, optically. The timing at which the maximum one among average densities read from the patterns is obtained, can be set as the printing registration condition. Further, a processing including a coarse adjustment to a fine adjustment is performed in a series of algorithm. By these processings, printing registration between a forward and a reverse scan of a print head or printing registration between a plurality of print heads in a printing apparatus can be performed simply and with high accuracy, without operating by a user.

摘要： In an image processing method, on the basis of input image data with respect to a target pixel, independent multi-level data (g0, g1) corresponding to respective plural species of dots which are different in at least one of a density and a diameter are generated, and then data (O0, O1) relating to an amount of generation of the dots with respect to the target pixel are generated on the basis of a relationship between the generated independent multi-level data (g0, g1) corresponding to the plural species of dots. The image processing method is effective in performing design having a high degree of flexibility in proper use of a relatively high power dot (high density dot or large dot) and a relatively low power dot (low density dot or small dot) and can realize obviation or alleviation of an occurrence of granulation or an apparent frame caused due to the relatively high power dot.

摘要： To reduce the number of simultaneously driven printing elements so that the instantaneously flowing current is restricted in a printing system for completing an image by repeating the printing scan a plurality of times in the same printing area while applying random mask thereto. For this purpose, a mask of a predetermined size is structured as a thinning pattern in which data are arranged randomly, the data being for determining whether or not the respective ink ejection openings in a printing head are to be driven when the printing head repeats the scan a plurality of times in the same printing area of a printing medium. When forming an image, the printing elements concerned with the printing operation in the same printing area are divided into a plurality of sections, and the thinning patterns complementary to each other are applied to the respective sections during the respective printing scans.

摘要： A construction of a printing apparatus wherein a printing registration with respect to forward and reverse scans of a printing head and a printing registration with respect to a plurality of printing heads are automatically carried out is realized without rendering the apparatus complex or causing its production cost to rise. To this end, the optical sensor for measuring patterns formed for use in printing registration is also used to serve other purposes such as a detection of a printing home position or a detection of a printing medium's end. Furthermore, by appropriately controlling a single optical sensor according to each of various intended purposes, the optimum characteristics are utilized in each respective operating mode. Because of the above, the addition of sensors to be used only for the purpose of printing registration and the accompanying rise of the print apparatus production cost are restrained.

摘要： A printing apparatus can reduce degradation in print quality of a printed image, notably in a highlight portion or an intermediate gradation portion, in the case where the image is printed by forming dots of a plurality of sizes. Specifically, data causing larger and smaller cyan ink droplets, respectively, to be ejected is independently subjected to a conversion to n-value process. Thus, the data for larger ink droplets is present in a portion of printing data which corresponds to the highlight portion or intermediate gradation portion of the image. During printing, larger dots are formed in this area, thereby making it difficult to perceive possible stripes caused by the offset of the positions at which smaller droplets impact a sheet.
摘要翻译：在通过形成多个尺寸的点来打印图像的情况下，打印装置可以降低打印图像的打印质量的劣化，特别是在高亮部分或中间灰度部分。具体地说，分别使喷出较大和较小的青色墨滴的数据被独立地转换为n值处理。因此，用于较大墨滴的数据存在于对应于图像的高亮部分或中间灰度部分的打印数据的一部分中。在打印期间，在该区域中形成较大的点，从而难以察觉由较小液滴撞击片材的位置的偏移引起的可能条纹。

摘要： An apparatus and method capable of obtaining an output characteristic of the print unit and determining a correction value for an output density, without using an expensive scanner. To realize this, a nozzle array consisting of a plurality of nozzles provided in the print head is divided into a plurality of nozzle blocks [a] to [d] and each of patches is formed by using the nozzles of the same nozzle block allocated to the patch. The patches are printed in a size and shape that allows the densities of the patches to be optically detected by the density sensor. A test pattern comprising these patches is measured by the density sensor to make a density correction for each nozzle of the print head.

摘要： A print method that uses a printer apparatus based on a multi-pass printing method to reduce the unevenness of colors associated with a scanning direction, even during bidirectional color printing. For this purpose, sets of two print heads that apply cyan (C), magenta (M), and yellow (Y) inks are arranged to be symmetrical in the scanning direction so that a plurality of secondary color pixels arranged in a raster direction can be formed by changing an ink application order (C→M and M→C). Consequently, the pluralities of secondary color pixels arranged in the raster direction undergo the different ink application orders, so that the application order remains the same whether the pixels are formed during forward or backward scanning. Therefore, the unevenness of colors associated with the ink application order can be reduced.
摘要翻译：即使在双向彩色打印期间，使用基于多遍打印方法的打印机装置来减少与扫描方向相关联的颜色的不均匀性的打印方法。为此，应用青色（C），品红色（M）和黄色（Y）墨水的两个打印头的组被布置为在扫描方向上对称，使得沿光栅方向布置的多个次要颜色像素可以通过改变油墨应用顺序（C-> M和M→C）形成。因此，排列在光栅方向上的多个次色像素经受不同的墨水施加次序，使得在正向或反向扫描期间形成像素时，施加顺序保持相同。因此，可以降低与油墨施加顺序相关联的颜色的不均匀性。
