摘要:
A computer implemented method of producing personalized documents comprising the steps of inputting handwritten alphanumeric characters which are then mapped into at least one set of text characters. A textural document is entered into the computer and is transcribed into a set of text characters corresponding to the input handwritten alphanumeric characters. The document can be printed and will contain text in the handwriting of the person whose alphanumeric characters were used as input.

A three-dimensional halftone screen is provided that is suited for multilevel printing. The three-dimensional halftone screen includes a plurality of planes each corresponding to one or more input intensity levels of an input RIPped pixel. Within the planes are screen dots, each associated with one or more output exposure intensity values representing an intensity of an exposure dot corresponding to the input RIPped pixel.

Techniques for color gamut mapping between source and destination devices are provided. The mapping is performed in a device-independent color space using color ridges of the primary and secondary color ramps of the source and destination devices. An iterative learning process is also provided to adapt the color gamut mapping to a user's perceptual preferences.

One or more printers or printing systems are connected to a scanning device. Each printer includes one or more color modules that are used during a printing operation. A printer prints a target for each color module or color channel. The printed targets are then scanned by the scanning device. The printed targets may be rotated to any angle and then scanned by the scanning device. The scanned raster data is processed by a controller to detect non-uniformities in at least one density image and to generate one or more correction profiles for the printer. When an image is to be printed, one or more controllers receive the image data and use the one or more correction profiles to correct or compensate for the non-uniformities during the exposure process.
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:
A method of printing comprising the steps of detecting a contour in a first color space image, locating the contour, mapping the image into the second image space, and changing the mapping curve shape, changing the printer profile (e.g. changing the printer mapping function), editing the image, or other method to reduce or eliminate perceived contouring.

Apparatus for depositing a texture on a receiver includes a data source that provides multilevel input tint data values based on a job specification. 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.
