    • A method for reduction of differential gloss as found in hardcopy image prints. The method comprises selecting a first halftone having a high apparent gloss characteristic and a second halftone having a low apparent gloss characteristic while retaining an identical matching density characteristic to the first selected halftone. a A determination is then made of which areas of the halftone image correspond to potentially high gloss and low gloss regions under normal printing conditions. The first halftone is applied to those portions of the halftone image determined as corresponding to potentially low gloss regions, and the second halftone is applied to those portions of the halftone image determined as corresponding to potentially high gloss regions of the halftone image.
    • 降低印刷图像印刷中所见的差异光泽的方法。 该方法包括选择具有高表观光泽特性的第一半色调和具有低表观光泽特性的第二半色调,同时保持与第一选定半色调相同的匹配密度特性。 然后,在正常打印条件下,确定半色调图像的哪些区域对应于潜在的高光泽度和低光泽度区域。 将第一半色调施加到被确定为对应于潜在的低光泽区域的半色调图像的那些部分,并且将第二半色调施加到被确定为对应于半色调图像的潜在高光泽区域的半色调图像的那些部分。

    • A method for reduction of differential gloss as found in halftone image hardcopy prints. The method comprises selecting either a single halftone or employing two halftones: a first halftone having a high apparent gloss characteristic; and a second halftone having a low apparent gloss characteristic. A determination is then made of which areas of the halftone image correspond to potentially high gloss and low gloss regions under normal printing conditions. An overlay of clear toner is applied to the hardcopy print of the halftone image. In one approach a single halftone is employed to control the physical area coverage of the applied clear toner layer so as to adjust the local gloss across for the determined regions and thereby balance the evenness of gloss across the entire hardcopy print of the halftone image. Greater physical area coverage is provided as controlled by the single halftone in low gloss regions, and corresponding less physical area coverage is provided in the low gloss regions. In a further approach two halftones are employed. The first halftone is directed to those portions of the overlaid clear toner determined as corresponding to potentially low gloss regions of the halftone image, and the second halftone is directed to those portions of the clear toner layer determined as overlaying potentially high gloss regions of the halftone image.
    • 减少在半色调图像硬拷贝印刷品中发现的差别光泽的方法。 该方法包括选择单个半色调或采用两个半色调:具有高表观光泽特性的第一半色调; 和具有低表观光泽特性的第二半色调。 然后确定半色调图像的哪些区域在正常打印条件下对应于潜在的高光泽度和低光泽度区域。 将透明调色剂的覆盖层应用于半色调图像的硬拷贝印刷。 在一种方法中,使用单个半色调来控制施加的透明调色剂层的物理面积覆盖,以便调整所确定区域的局部光泽度,从而平衡半色调图像的整个硬拷贝印刷品的光泽均匀度。 在低光泽区域由单一半色调控制提供更大的物理面积覆盖,并且在低光泽区域中提供相应较少的物理面积覆盖。 在另一方面,采用两个半色调。 第一个半色调指向重叠的透明调色剂的那些部分,这些部分被确定为对应于半色调图像的潜在的低光泽区域,并且第二半色调指向被确定为覆盖半色调的潜在高光泽区域的透明调色剂层的那些部分 图片。

    • The present invention relates to expanding the range of image densities over which the manipulation of differential gloss as may be inherent in halftoned images may be achieved. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density, a gloss image may be superimposed within an image without the need for special toners or paper. This technique may be enhanced across low and high density areas by application of clear toner. Further, in color systems, light color toner may be applied to low density image areas and dark under-color applied in high density image areas, to expand the range of image densities over which a desired glossmark image will bear an effect.
    • 本发明涉及扩大可以实现半色调图像固有的差分光泽操作的图像浓度的范围。 通过选择性地施加各向异性结构特征的半色调,其在取向上显着不同,同时保持密度相同,可以在图像内叠加光泽图像,而不需要特殊的调色剂或纸张。 通过使用透明调色剂,可以在低密度和高密度区域增强该技术。 此外,在色彩系统中,可以将浅色调色剂施加到低密度图像区域和深色底色施加在高密度图像区域中,以扩大图像浓度的范围,期望的光标图像将在该范围内产生影响。
