摘要： A printing apparatus and print control method, capable of using plural types of printheads, can achieve high throughput by performing optimized print control in accordance with the type of printhead and the number of printheads used. In a case where the printing apparatus adopting such print control method includes, e.g., four printheads, and performs printing on a print medium by reciprocally scanning the printheads, detection is first performed as to whether only one printhead which discharges black ink is mounted or four printheads which respectively discharge black, yellow, cyan and magenta ink are mounted; decision is made on a printing period of the printhead based on the detected result; then decision is made on a scanning speed of the printhead based on the decided printing period; and the printhead is driven based on the decided printing period and scanning speed to perform printing.

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 in 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，以ODt和（ODn-ODt）的值分别除以上述区域中包括的像素数来表示。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： The present invention suppresses data processing load and processing time when generating density data for the same color that corresponds to a plurality of printing scans (or plurality of printing element groups) of a printing head and printing medium. In order to accomplish this, input image data is converted to a plurality of density data by referencing a three-dimensional lookup table that performs one-to-one correlation of input image data with a plurality of density data that corresponds to a plurality of relative movements (or plurality of printing element groups). By doing so, it is possible to perform a process of generating density data (CMYK) that corresponds to a plurality of relative movements (or plurality of printing element groups) from input image data at once, and thus it is possible to suppress an increase in data processing load and processing time.
