摘要： The purpose is to provide a high quality halftone recording with a reduced grainy feeling without lowering the true resolving power. Provided is an apparatus for making a halftone recording by employing three or more types of color materials, each of which has at least one grade of concentration, wherein each type of the color materials having the lowest concentration provides, when recording on a recording medium having a first lightness, a recorded region having its own lightness, and wherein a difference between the first lightness and the lightness of the recorded region is not more than 35, the lightness being measured according to the definition of CIE 1976 psychological measurement lightness using a standard illuminating light D65 as a light source.

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： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.

摘要： In a multi-scan method for printing a printing area by n (4) scans of a head and printing individual scan lines with n different ejection ports, a paper feed amount of transporting performed between the individual n scans is set to a value less than an amount of {(a length of total ejection port)/(n-1)}, and thereby close ejection ports in the ejection port arrangement in the head can be used as the n ejection ports for the individual lines, and an application position deviation between the ejection ports for individual lines due to a head mount error or the like can be reduced. As a result, unevenness of density due to deviation of dots in a scanning direction can be suppressed.
