Abstract: Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.

Abstract: Various variable gloss reduction techniques are disclosed. In one embodiment, a gloss reduction technique is disclosed using a textured roller and a wiper impregnated with fuser oil to create a differential gloss pattern that reduces the gloss of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a combination of heat and pressure to create a differential gloss pattern that reduces the gloss in specific regions of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a differential gloss pattern to generate a security mark on a printed image to prevent against copying or fraudulent misrepresentation of the image.

Abstract: The smoothness of a toner layer is reduced and thus the gloss of a resulting print is reduced. A single toner, the original high gloss version, is enabled to print all images. A finishing option is provided which, through application of a combination of heat and pressure with a textured roller, reduces the specular gloss of the toner surface by imprinting a high frequency texture onto the smooth toner layer. By adjusting the temperature/pressure of the textured roller, the effective gloss of the press can be adjusted through software as desired.
Abstract translation: 调色剂层的平滑度降低，从而降低了所得印刷品的光泽度。 原始高光泽版本的单一墨粉可以打印所有图像。 提供了一种整理选项，其通过将加热和压力的组合与纹理化辊组合使用，通过将高频纹理压印到光滑调色剂层上来降低调色剂表面的镜面光泽度。 通过调整纹理辊的温度/压力，可以根据需要通过软件调节印刷机的有效光泽度。
