摘要： An image processing apparatus has a dynamic range compression unit that converts an input luminance signal included in a developed data into an output luminance signal by using a conversion parameter. The unit obtains an input black reference luminance value and an input white reference luminance value of the luminance information included in the developed data. The unit, on a basis of print medium information and observation environment information, obtains an output black reference luminance value and an output white reference luminance value and calculates a reference output luminance value for observation. The unit generates a conversion line and generates the conversion parameter by using the conversion line. The conversion line indicating a correspondence between the input luminance signal and the output luminance signal.

摘要： A printing apparatus includes an image processing unit and generates a product by performing printing on a print medium conveyed in a conveyance direction intersecting a width direction, based on data for printing, and then cutting a width-direction end portion of a printed image, wherein the image processing unit calculates a first ink application amount of a first area formed at one end portion in the width direction on a leading edge side of the image which is located on a downstream side in the conveyance direction during printing and a second ink application amount of a second area formed at the other end in the width direction on the leading edge and enlarges the image data at a predetermined ratio to obtain the data for printing in a case where at least one of the first ink application amount and the second ink application amount exceeds a threshold value.

摘要： A printing apparatus provides a conveyance operation in which a conveyance unit conveys a print medium in a conveyance direction, and includes a control unit to control a printing unit such that, in a case where an image is to be printed onto a print medium of a first type in a first state in which the print medium of the first type is supported by a first conveyance member and not supported by a second conveyance member, the printing unit uses a printing element included in a first region from which a distance to the print medium of the first type in a height direction perpendicular to a surface where the printing elements are arrayed is a first distance, and does not use a printing element included in a second region from which a distance to the print medium of the first type in the height direction is a second distance greater than the first distance.

摘要： In a color mode, among clear ink data CL1 and CL2, only the data CL2 is set to a uniform use amount of 20%, while the use amount for the data CL1 is set to zero. Meanwhile, in a monochrome photo mode, the data CL1 indicates a usage of 10% to 40% near a white point, but starting at the intermediate gradations the data CL1 use amount decreases while the data CL2 use amount increases, with a data CL2 use amount of 20% near a black point. In so doing, it is possible to sufficiently suppress bronzing in the color mode where coloring ink data exists, without imparting a particularly strong unnatural look except for specific colors. Meanwhile, in the monochrome photo mode where coloring ink data does not exist, high-level suppression of bronzing is possible, at the cost of a slight reduction in the glossiness of the printed material.
摘要翻译：在彩色模式中，在清晰墨水数据CL1和CL2中，只有数据CL2被设置为20％的均匀使用量，而数据CL1的使用量被设置为零。同时，在单色照片模式下，数据CL1表示在白点附近使用10％至40％，但是从中间灰度开始，数据CL2使用量随着数据CL2使用量的增加而减少，数据CL2使用量增加 20点附近的黑点。在这样做时，可以充分抑制着色油墨数据存在的色彩模式中的烫金，除了特定的颜色之外，不会产生特别强烈的不自然的外观。同时，在不存在着色油墨数据的单色照片模式中，以打印材料的光泽度的轻微降低为代价，可以高水平地抑制烫金。

摘要： Provided is an ink jet printing apparatus that, without causing an increase in apparatus size, can print an image having high evenness in both of image clarity and glossiness regardless a gradation or gamut of the image. For this purpose, on the basis of input image data, pieces of multivalued color data respectively corresponding to colored inks, and first multivalued data and second multivalued data that correspond to image enhancing liquid are generated. On a print medium, the colored inks and the image enhancing liquid according to the first multivalued data are printed at nearly the same timing, and after the printing of them has been completed, the image enhancing liquid according to the second multivalued data is printed. In doing so, gloss properties appearing on the print medium can be made to fall within certain ranges, respectively, independently of input image data.
摘要翻译：提供了一种喷墨打印设备，其不会导致设备尺寸的增加，而不管图像的灰度或色域如何，均可以以图像清晰度和光泽度两者打印高均匀度的图像。为此，基于输入图像数据，生成分别对应于彩色墨水的多值颜色数据和对应于图像增强液体的第一多值数据和第二多值数据。在打印介质上，根据第一多值数据的彩色油墨和图像增强液体以几乎相同的定时打印，并且在其打印完成之后，打印根据第二多值数据的图像增强液体。在这样做时，独立于输入图像数据，出现在打印介质上的光泽性能可以分别落在一定范围内。

摘要： A generation unit, which is configured to process image data to generate print data for applying an ink and a reaction liquid such that the print data corresponds to respective passes, generates print data for the ink such that the ink is applied only in a pass of which the elapsed time after application of the reaction liquid to the print medium is equal to or longer than the first time and shorter than the second time. The first time is from the timing where the reaction liquid is applied to the print medium up to the timing where adjacent droplets of the applied reaction liquid come into contact with each other and coalesce to form a reaction liquid film. The second time is from the timing where the reaction liquid is applied to the print medium up to the timing where the formed reaction liquid film is dissolved.

摘要： An object is to reduce deterioration of image quality at a leading edge portion and a trailing edge portion of a high-stiffness print medium. To achieve that, in a case of printing an image onto a leading edge portion of the print medium in its conveyance direction, the image is printed using printing elements included in a region in a printing element region that is close to a first conveyance member on the upstream side. Also, in a case of printing an image onto a trailing edge portion of the print medium in the conveyance direction, the image is printed using printing elements included in a region in the printing element region that is close to a second conveyance member on the downstream side.
