摘要： A printing apparatus includes a plurality of inkjet print heads to which humidified air is supplied to retain the humidity in the print heads. Ink colors for the plurality of heads are arranged in a sequence corresponding to ink characteristics. The plurality of print heads are arranged in a sequence such that a print head configured to eject ink characterized by having a larger amount of volatile components evaporated within a predetermined time is located in a more upstream area.

摘要： A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.

摘要： An image processing apparatus which previously sets a reduction order based on saturation with respect to inks to be used in a saving mode. When a color uses two or more colors of ink, the image processing apparatus reduces the ink featuring high on the reduction order, or increases the reduction amount of the ink featuring high on the reduction order.

摘要： For M (magenta) and C (cyan), in a case of generating, e.g., ternary data of C0 to C2 and M0 to M2 respectively by using a look-up table on the basis of an error diffusion method, in a highlight portion of input M and C data (to which errors Ce and Me have been added respectively), a conversion space of correlating these data is used, while in a high-density portion, a conversion space equivalent to ordinary error diffusion is used. Thus, in a case of converting multivalued color image data into data of a lesser number of bits than the number of bits of color components constituting the multivalued color image data, it is possible to maintain excellent tonality on the entire image, and particularly to control graininess by preventing image quality deterioration in the highlight area.

摘要翻译： 对于M（品红色）和C（青色），在通过使用基于误差扩散方法的查找表分别产生C 0至C 2和M 0至M 2的三进制数据的情况下， 在输入M和C数据的高亮部分（分别添加有错误Ce和Me）的高亮部分中，使用与这些数据相关的转换空间，而在高密度部分中，与普通误差扩散相当的转换空间是 用过的。 因此，在将多值彩色图像数据转换成比构成多值彩色图像数据的色彩分量的位数少的数据的数据的情况下，可以在整个图像上保持优良的色调，特别是控制 通过防止高亮区域的图像质量劣化而发生颗粒感。

摘要： An ink jet printing method prints an image on a printing medium by ejecting ink and printabilty improvement liquid containing a substance for improving printablity of the ink to the printing medium. At this time, ejection of the ink and ejection of the printability improvement liquid onto the printing medium are achieved such that the position where the printability improvement liquid is applied and the position where the ink is applied are different from each other, but partially overlap when the ejected printability improvement liquid comes into contact with the ejected ink on the printing medium.

摘要： When an image is recorded using a multichip recording head including a plurality of chips each having a plurality of nozzle arrays, a change in image density can occur due to a registration error between chips in an overlapping part where two chips are connected. To suppress the change in image density, input image data is distributed to two chips such that there are dots overlapping each other between the two chips in the overlapping part.

摘要： A signal value representing at least one of a plurality of types of optical characteristics are calculated for each pixel from the read signal obtained and output by reading light reflected by a document placed on a document table and a document table cover while the document is covered with the cover. It is determined, based on the signal value calculated, whether or not a target pixel is a pixel in a document region. A document region is detected from the determination result.
