摘要:
A printing machine that records information about resources expended to carry out a printing request. The recorded resource information may include quantities of particular paper types and colored toner needed to satisfy the printing request. Subsequently, before carrying out another printing request, the printing machine uses the recorded information to make a prediction or estimate of resources required to carry out the printing request. The printing machine thus reduces uncertainty about whether there are sufficient resources to satisfy the next request, and alleviates the burden of maintaining excessive consumables in inventory.

A method of developing a job for output with an output subsystem is provided. The method includes generating a first electronic representation of a first image at a first time, reading a subset of placemarking instructions at a second time, generating a second representation of a second image at a third time, wherein the second time is after the first time but before the third time. At a fourth time, which fourth time is after the first, second and third times, a selected function is performed relative to a third electronic representation of a third image in response to the reading of the subset of placemaking instructions.

A method and apparatus which improves the precision of a color look-up table used to transform from the input image's color space to device-dependent print engine color space. The generated look-up table includes nodes in excess of those necessary for a single image transformation. A node selecting device allows for the selection of a subset of the nodes in accordance with image requirements which can be determined either alone or in combination, a distribution of color content of the image throughout the print engine color space, or customer-defined critical color regions.

In color printing the quality of the image reproduced depends upon factors which include the type of image processing chosen, which affects the amount of colorant consumed; the type of paper used, uncoated or coated; and optional coatings applied thereto. The cost of a printing job can be significantly affected by the amount of colorant and the quality of paper used. A method of changing the factors affecting image quality and determining the cost of the job based on the output image quality is disclosed. This method allows a customer to choose the desired image quality versus cost trade-offs for a printing job.
摘要:
Systems and methods are presented in which a print job is segmented into multiple parts or chunks prior to facilitate raster image processing by including in each of the parts the print job preamble, one or more page portions, and only those resources required for the page portions, and the generated chunk files are provided to one or more raster image processing components for rendering or printing.
摘要:
A softproofing system and method render an input document for display on a monitor to faithfully represent projected output from a target print engine, where the displayed document representation rendering is modeled to include internal print engine specific enhancements or characteristics of the target print engine. The system and method identify the target print engine and print engine specific rendering characteristics from the specified content, such as an input file, which may be a raster image or an electronic file in a PDL format. Specific print engine characteristics may include halftone screen identification, error diffusion identification, halftone dot shape, write white, write black, anti-aliasing, line width compensation and specific tone reproduction curves.
摘要:
A method and system for selective application of AIE (Automatic Image Enhancement) based on the characteristic of an image. The image can be evaluated utilizing PDL data, object location data, image layering data, image overprint data and image raster data in combination with a weighting scheme to ascertain whether the image should be designated as a background or watermark. The designated images can be passed through a tag to a DFE (Digital Front End) application in order to determine the application of AIE to the images.
摘要:
What is disclosed is a novel system and method for selecting a printer in a document reproduction environment comprising a plurality of networked printing devices. In one embodiment, a document is received which is to be printed and a set of image quality requirements specific for the document are determined based on the document's image content. A threshold quality expectation level is set for the document based on the set of image quality requirements. Device specific image quality metrics are obtained for each of the networked printing devices and then compared with the threshold quality expectation level. A printing device which best exceeds the threshold quality expectation level is selected as a result of the comparison. The document is sent to the selected networked printing device. If none of the networked printing devices is found to meet the threshold then an operator is signaled that the document cannot be printed.

An automated document template creation method comprises: inputing data of an existing document that contains a visual design to input an image; decomposing the image into at least one object using at least one image processing technique; determining at least one design attribute of the object; and synthesizing a document template containing the design attribute. An automated document template creation system comprises: an input device that receives data of an existing document containing a representative visual design to obtain an image; an image processor that decomposes the image into at least one object and determines at least one design attribute of the object; and a template creator that synthesizes a document template containing the design attribute. The systems and methods allow a scan/preparation user at a makeready station to generate additional and/or replacement pages for an existing document that are visually coherent with the predetermined visual design of the document.
摘要:
A method and system for determining chromatic content of a page of an electronic document. Object level color analysis is performed on a page of the electronic document to determine whether the page is chromatic, achromatic or has highlight color, based on the object level color analysis. The page is then classified as chromatic, achromatic or highlight color, based on the results of the determination.
