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.

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： A system and method for selective color-correction when applying three-dimensional texture to a printed substrate hinges either on a metric that is elicited from the image, or as determined by an operator. The metric may be associated with the human visual acuity curve for textural information. Other textural metrics may also be used.
