    • A method of identifying color mismatches for objects having different rendering intents within a print job prior to printing, includes identifying all objects within the print job, each object's type, rendering intent and all source colors associated with it; for each object in the print job, transforming each object's source colors using a prototypical color transformation; identifying sets of transformed objects having source colors that match within a first tolerance; transforming all transformed objects using a target printer's color space; identifying any of the transformed objects in each set that do not match within a second tolerance level; identifying any object types within the group of mismatched objects having at least two different rendering intents; selecting one of the rendering intents in accordance with a predetermined criterion; and assigning the selected rendering intent to at least one other instance of that object type.
    • 一种在打印之前识别打印作业内具有不同渲染意图的对象的颜色不匹配的方法包括识别打印作业内的所有对象,每个对象的类型,呈现意图和与其相关联的所有源颜色; 对于打印作业中的每个对象,使用原型颜色转换来转换每个对象的源颜色; 识别具有在第一公差内匹配的源颜色的变换对象的集合; 使用目标打印机的颜色空间转换所有转换的对象; 识别每个集合中在第二公差级别内不匹配的任何转换对象; 识别具有至少两个不同呈现意图的不匹配对象组内的任何对象类型; 根据预定标准选择一个渲染意图; 以及将所选择的呈现意图分配给该对象类型的至少一个其他实例。

    • The presence of a radio frequency signature (88) on a cut sheet of print media (28) is detected by a radio frequency interrogating device (94) to determine it's relative left/right position on the print media (28). Either the leading edge (124) or trailing edge (126) of the print media (28) is detected by one or more print media sensors (86, 90). A print controller (24) can note the time (t1) when print media is detected and cause the radio frequency interrogating device (94) to detect the radio frequency signature (88) at a time (t2) when the print media has reached a predetermined point along the print media pathway (110). The position of the radio frequency signature (88) on the print media (28) can be calculated using the time differential (t2-t1) and the known angular displacement of the radio frequency interrogating device (94).
    • 通过射频询问装置(94)检测在打印介质(28)的切片上的射频签名(88)的存在,以确定其在打印介质(28)上的相对左/右位置。 打印介质(28)的前缘(124)或后缘(126)都被一个或多个打印介质传感器(86,90)检测到。 当检测到打印介质时,打印控制器(24)可以记录时间(t 1> 1),并且使得射频询问装置(94)一次检测射频签名(88) 当打印介质已经到达沿着打印介质路径(110)的预定点时。 射频签名(88)在打印介质(28)上的位置可以使用时间差(t 2 -T 1 -T 1)和已知的角位移 的射频询问装置(94)。

    • A radio frequency signature (88) on a cut sheet of print media (28) is detected by a radio frequency interrogating device (94) to determine whether the print media (28) is properly oriented. The leading edge (124) or trailing edge (126) of the print media (28) is detected by one or more print media sensors (86, 90). A print controller (24) can note the time (t1) and cause the radio frequency interrogating device (94) to detect the radio frequency signature (88) at a time (t2) when the print media has reached a predetermined point along the print media pathway (110). The position of the radio frequency signature (88) on the print media (28) can be calculated using the time differential (t2−t1), the velocity profile of the print media and the known separation between the print media (28) and the radio frequency signature (88). By comparing the computer position with the expected position, the orientation of the print media (28) can be determined.

    • A computer-implemented method of matching color elements for objects having different source color definitions within a print job prior to printing, includes identifying all source colors to be printed within the print job and object type associated with each instance of a source color; identifying any source colors having at least two different source color definitions; for each source color having at least two different source color definitions, selecting one of the source color definitions in accordance with a predetermined criterion; and assigning the selected source color definition to at least one other instance of the source color for that object type. The predetermined criterion may include for each source color having at least two different source color definitions for the same object type, assigning the selected source color definition to all other instances of the source color for that object type.
