    Abstract: PROBLEM TO BE SOLVED: To provide technique to realize digital half tone which controls a spot function in order to cope with gear noise, printer stress and general printing quality. SOLUTION: A method for forming spots to be used for realizing half tone includes a step for defining a spot function combining two functions which are selected in order to provide a prescribed spot form to be used in a half tone cell, and a step for scaling the spot function by using a scaling function which changes in accordance with values of a first spot function ordinate and a second spot function ordinate. By using asymmetrical modulation of the spot function, contact of adjacent spots is controlled, and a form of the spot accompanied by a gray region is changed.

    Abstract: PROBLEM TO BE SOLVED: To provide a color management system that includes a new type of CMR called a "link color conversion CMR(color management resource)". SOLUTION: Color management at end point devices such as a display or printer is carried out, based on CMR (color management resource). A CMR is an architected resource stored accessibly to a print server 102 or other processor and is used for holding all of color management information required for rendering of a print file, document, page, or data object. In particular, a linked color conversion rule is created, by coupling a unique descriptor to each input/output color conversion rule and combining input/output color conversions. A linked color conversion structure contains three parts, a descriptor for input color conversion rule, a descriptor for output color conversion rule and the coupled color conversion rules. By comparing the descriptors, identification of an existing linked color conversion that combines the input/output conversions can be made very rapidly. COPYRIGHT: (C)2006,JPO&NCIPI

    解决方案:基于CMR(颜色管理资源),执行端点设备(如显示器或打印机)的色彩管理。 CMR是可存储于打印服务器102或其他处理器的架构资源,并且用于保持呈现打印文件,文档,页面或数据对象所需的所有颜色管理信息。 特别地,通过将​​唯一描述符耦合到每个输入/输出颜色转换规则并组合输入/输出颜色转换来创建链接的颜色转换规则。 链接的颜色转换结构包含三部分,输入颜色转换规则的描述符,输出颜色转换规则的描述符和耦合的颜色转换规则。 通过比较描述符,组合输入/输出转换的现有链接颜色转换的识别可以非常快速地进行。 版权所有(C)2006,JPO&NCIPI
