    摘要: A method of calculating compensation data for compensating for spatial print engine non-uniformity of an image applied by a print engine to a receiver. A test target has two test areas of different output densities, each with a single output pixel level. A relationship between output density and output pixel level for the print engine is determined, and is used to calculate the output pixel level for each test area from the respective output density. The test target is printed, and the reproduced densities of the test areas are measured at a plurality of different locations in each area. A processor is used to calculate the compensation data using the measured densities. The compensation data defines a relationship between an output pixel location on the receiver, an output pixel level, and a compensated pixel level.

    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: An apparatus and method for calibrating a multi-color imaging system are provided. Color values are measured for each of the different color patches, and compared to target process-sensitive colors color values, representing a weight-adjusted memory color. An error value is calculated. The error value represents a deviation of the measured color values from the target color values. The input values for each colorant then are independently adjusted to reduce the error value to a predetermined degree.

    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.
