摘要： In the case of printing in three-value level utilizing two kinds of inks mutually different densities for one color (higher and lower density inks), it is assumed that a reflection density of a region having a predetermined area when solid print is performed only by the lower density ink, and that when solid print is performed only by the higher density ink are expressed ODt and ODn, respectively. Since the granular appearance of the ink dots is expressed in terms of reflection density of one dot, the granular appearance of a lower density ink dot at a portion of image formed only by the lower density ink dots and the granular appearance of a higher density ink dot at a portion of image formed by the higher and lower density ink dots are expressed in terms of values of ODt and (ODn-ODt) divided by the number of pixels included the above region, respectively. Accordingly, by making the reflection density ODt to be approximately one half of the reflection density ODn, the granular appearance produced by the lower density ink dot at the highlighted portion and the granular appearance produced by the higher density ink dot at the portion where the higher density ink dots scattered in the lower density ink dots can be made substantially equal to each other. For this purpose, it is preferable that a dye concentration of the lower density ink is to be about one fourth of that of the higher density ink.
摘要翻译：在使用两种不同浓度的油墨（高浓度和低浓度油墨）的三值油墨印刷的情况下，假设仅在实施印刷时由具有预定区域的区域的反射浓度较低密度的墨水以及仅通过较高密度墨水进行固体印刷时分别表示为ODt和ODn。由于墨点的粒状外观以一点的反射密度表示，所以在仅由较低密度墨点形成的图像部分处的较低密度墨点的粒状外观和较高密度墨水的粒状外观通过高密度和低密度墨点形成的图像的一部分，分别以除了上述区域的像素数除以ODt和（ODn-ODt）的值表示。因此，通过使反射密度ODt为反射密度ODn的大约一半，由突出部分的低密度墨点产生的粒状外观和高密度墨点在较高密度墨点处产生的粒状外观可以将分散在较低密度墨点中的密度墨点基本上彼此相等。为此，较低浓度油墨的染料浓度优选为较高浓度油墨的浓度的约四分之一。

摘要： In a printer, when difference in ejection characteristic among nozzles appears as density non-uniformity and the way of letting the density non-uniformity appear is different depending upon kind of image, proper density correction is performed. Specifically, the kind of image to be printed is judged, and when the kind of image is a halftone image according to the judgment, a density correction table corresponding to the halftone image is selected and used to perform the density correction. Also when the kind of image is judged to be a solid image (without a portion of the halftone image), a proper table is selected similarly and used to perform the density correction.

摘要： An image processing apparatus processes multivalued color image data that includes a plurality of color components. The apparatus includes an adding unit to add per-color-component quantization error values from a neighboring pixel to respective ones of a plurality of color components included in a pixel of interest, and a quantization unit to correlate a sum of the values of each of the color components to which the error value has been added by the adding unit to a sum of values after conversion, and deciding the value of each color component after conversion upon distributing the sum of pixel values after the conversion in accordance with the ratio of each of the color components before conversion. In addition, a coefficient decision unit decides diffusion coefficients, which diffuse quantization error to neighboring pixels, based upon the value of each of the plurality of color components included in the pixel of interest.

摘要： A printing apparatus and a print position aligning method are provided which can execute a dot position adjust value calculation mode normally and smoothly without requiring the user to make decisions or adjustments. A test pattern to check the width of a print medium is printed and is detected by an optical sensor to decide whether or not a dot position adjustment pattern can be printed. Before the dot position adjustment pattern is printed, a decision is made as to whether the print medium supplied is appropriate or not. If the print medium supplied is smaller than a size specified for the dot position adjust value calculation processing, the print medium is discharged without being printed with the dot position adjustment pattern. This eliminates a possibility of a wasteful consumption of print mediums and of contaminating the interior of the printing apparatus.

摘要： Two print heads combined for each ink color are arranged symmetric to each other with respect to the scan direction and are used for a bidirectional printing. In producing secondary colors, image data is spread-processed by using a “diagonal arrangement” spread pattern to differentiate the ink application order at one of dots arranged in the raster direction from those of the other dots and thereby reduce color variations in the scan direction. Further, when image data has a half-tone, a “horizontal arrangement” spread pattern, different from the previous one, is used to perform image processing on the image data to alleviate an undesired texture. To prevent a driving load from concentrating on only one of the paired print heads, the number of times that each nozzle is driven is counted and an adjustment is made to spread the frequency of use among the two paired print heads.
摘要翻译：对于每种墨水颜色组合的两个打印头相对于扫描方向彼此对称布置，并用于双向打印。在生成二次色时，通过使用“对角排列”展开图案来对图像数据进行扩展处理，以便在光栅方向上排列的一个点与其他点的点之间的墨水应用顺序区别开，从而减少扫描方向的颜色变化。此外，当图像数据具有半色调时，使用与前一个不同的“水平排列”扩展图案来对图像数据执行图像处理以减轻不期望的纹理。为了防止驱动负载仅集中在一个打印头中的一个上，对每个喷嘴的驱动次数进行计数，并且进行调整以扩展两个成对的打印头之间的使用频率。
