摘要： A system and method for enhancing a print using a color imaging system are provided. The automatic color enhancement system results in digital prints that have a photographic “look and feel” by using special profiles and adjustments that capture the traditional photographic image process of photo-like color and tone scale reproduction to RGB-encoded picture elements and to be used to combine in with electrophotographic process media ICC profile.

摘要： Compensation is performed for nonuniformity in a printer. The printer has a photoreceptor and a print head with a plurality of different light sources, each light source capable of producing a plurality of different levels of light. A plurality of stored gain control signals for each light source are related to the light output of that light source. Print job data includes screened pixel levels and a halftone screen specification. The stored gain control signals are adjusted based on the halftone screen specification. The screened pixel levels are modified using the adjusted gain control signals to provide engine pixel levels. Those levels are provided to corresponding light sources to expose the photoreceptor in respective pixel areas with light corresponding to the compensated pixel levels.

摘要： Apparatus for depositing a texture on a receiver includes a data source that provides multilevel input tint data values. A lossy compressor produces compressed multilevel tint data values from the multilevel input tint data values. A decompressor produces multilevel decompressed tint data values from the compressed multilevel tint data values. A texture memory receives those values from the decompressor and provides corresponding multilevel texture pixel data values. A print engine deposits at each of a plurality of pixel sites on the receiver an amount of texture-forming material corresponding to the respective multilevel texture pixel data value. A loader loads into the texture memory a texture set including multilevel texture pixel data values for each of a plurality of textures, and each texture in the texture set corresponds to a respective selected range of multilevel decompressed tint data value.

摘要： Toner is applied to a receiver having an area to be folded and a separate area not to be folded. Non-fold and fold-area screening patterns are selected. The non-fold screening pattern has a toner coverage greater than 50% and the fold-area screening pattern has a toner coverage less than 50%. Image data to be applied to the receiver in the area to be folded and the area not to be folded are received. The image data in the area not to be folded are processed using the non-fold screening pattern and the image data in the area to be folded are processed using the fold-area screening pattern to provide screened data. Toner corresponding to the screened data is applied to the receiver. The applied toner is fused to the receiver, so that the area to be folded includes fused toner.

摘要： By using a high or low viscosity transparent toner, with respect to the other color toners, and different amounts of transparent toner lay-down, the gloss of an image printed by an electrophotographic device may be adjusted. By also applying the transparent toner as a negative mask, the differential gloss of the image may be reduced while still adjusting the gloss of certain portions of the image. Further, because different gloss levels may appear different at different viewing angles, transparent toner may be laid down to encode a transparent image within the image being printed. Such a transparent image may be useful as, for example, an authentication means for a document. Additionally, by varying the gloss levels on particular aspects of a printed image, multiple images of different gloss levels, which are prominent at different viewing angles can be made, thereby, a three-dimensional image effect can be achieved on the printed page.
摘要翻译：通过使用高粘度或低粘度的透明调色剂，相对于其它颜色调色剂和不同量的透明调色剂沉积，可以调节由电子照相设备印刷的图像的光泽度。通过将透明调色剂作为负面掩模，可以减小图像的差异光泽，同时仍然调节图像的某些部分的光泽度。此外，由于在不同的视角下不同的光泽度可能会出现不同，所以可以放置透明调色剂以对正在打印的图像内的透明图像进行编码。这样的透明图像可以用作例如文档的认证装置。另外，通过在打印图像的特定方面改变光泽度，可以制造出在不同视角下突出的不同光泽度的多个图像，从而可以在打印页面上实现三维图像效果。

摘要： Forming a multicolor image on a receiver member wherein a database of custom color profiles based on substrate physical properties and printing process characteristics is established. A set of universal color profiles is determined based on physical properties of substrates from clustered custom profiles. One universal color profile is assigned to a target substrate from the set of universal color profiles based on objective or subjective feedback. Thereafter, a multicolor toner image is formed on the receiver member with toners of at least three different colors of toner pigments which form various combinations of colors at different pixel locations on the receiver member to form the multicolor toner image thereon using the assigned one color profile. Based on objective or subjective feedback, the selected one universal color profile is modified, or a different universal color profile is selected.
