摘要： In printing using a plurality of chromatic color inks of different lightness interchangeable with one another in color reproduction, ink consumption is reduced while preserving the quality of the printed result. On the basis of first color data represented in terms of density of a first reference color, second color data represented in terms of density of a plurality of second reference colors is generated. The plurality of second reference colors are the ink colors. They include two same hue reference colors of different lightness interchangeable with one another when reproducing a certain color. The lookup table holds the first color data and the second color data associated with one another. For a set of densities of a plurality of second reference colors representing achromatic color of higher lightness than the reference lightness, density of the same hue reference color having lower lightness is 0. The reference lightness is lightness equal to or less than the minimum lightness which is the lightness of the color having the lowest lightness among the colors that can be reproduced on a printing medium using only ink of the darker color of the two same hue reference colors.
摘要翻译：在彩色再现中使用多种彼此可互换的亮度的彩色油墨进行打印时，墨水消耗减少，同时保持打印结果的质量。基于以第一参考颜色的密度表示的第一颜色数据，生成以多个第二参考颜色的密度表示的第二颜色数据。多个第二参考颜色是墨水颜色。它们包括在再现某种颜色时彼此可互换的不同亮度的两种相同的色相参考色。查找表保存彼此相关联的第一颜色数据和第二颜色数据。对于表示比参考亮度高的亮度的无色颜色的多个第二参考颜色的集合的集合，具有较低亮度的相同色相参考颜色的浓度为0.参考亮度是等于或小于最小亮度的亮度，其最小亮度是使用仅使用两种相同色相参考颜色的较暗颜色的墨的可以在打印介质上再现的颜色中具有最低亮度的颜色的亮度。

摘要： A paper feeding apparatus and a printer wherein an idle roller is brought into contact with a separation pad by a roller spring for generating urging force smaller than that of a separation pad for separating a paper sheet to be fed by a paper feeding roller having a D-shape side cross section from a next paper sheet; a restraining pin for restraining movement of the separation pad toward the paper feeding roller when the paper sheet is not held between the separation pad and the paper feeding roller is provided; a pair of conveying rollers are temporarily and inversely rotated after the leading end of the paper sheet has passed through a nipping portion between the pair of the conveying rollers and in a state where the paper sheet is not held between the separation pad and a circular-arc portion of the paper feeding roller so as to arrange the leading end of the paper sheet along the nipping portion so that diagonal conveyance of the paper sheet is smoothly prevented and the load acting on the fed paper sheet is reduced.
摘要翻译：一种送纸装置和打印机，其中空转辊通过辊弹簧与分离垫接触，用于产生比用于分离由具有D的进纸辊供纸的纸张的分离垫的推力小的推力从下一张纸张形成侧面横截面; 提供了当纸张没有被保持在分离垫和给纸辊之间时限制分离垫朝着给纸辊移动的限制销; 在纸张的前端通过一对输送辊之间的夹持部分之后，并且在没有将纸张保持在分离垫和圆形纸张之间的状态下，一对输送辊暂时反向旋转，使得纸张的前端沿着夹持部布置，从而平滑地防止纸张的对角输送，并且作用在进给纸张上的负荷减小。
