摘要： A method for improving tone reproduction in a digital printing system is provided. First, an image to be printed is defined. The image will have areas of minimal ink density and areas of medium to high ink density. A randomized dot placement scheme is used for dispersing ink drops in the minimal ink density areas of the image. An ordered structure scheme is used for dispersing ink drops in the medium to high ink density areas of the image.

摘要： A continuous multi-jet ink jet printer improves print quality in a high speed printer. The continuous multi-jet ink jet printer includes means for producing a rectangular array of ink drops, the array having columns corresponding to the consecutive drops in a single jet, and rows corresponding to drops simultaneously produced from all of the jets, where print drops and partially charged drops are printed on a print media and fully charged drops are deflected from the print media. Print quality is improved by selecting one or more print drops for printing and subjecting each of the one or more print drops to an equal amount of partial charging.

摘要： The present invention provides for selective droplet dispersion. The selective droplet dispersion technique of the present invention is used to optimize image quality from a continuous ink jet printer. Initially, a pixel to be printed is identified, and then placement of droplets within the pixel to be printed is selected to optimize image quality. The selection can be unconditional, wherein the placement of droplets is not dependent on neighboring pixels. Such selection includes printing first or last available droplets, or centering the droplets within the pixel to be printed. The selection can also be conditional, wherein placement of droplets is dependent on surrounding pixels. Such selection includes providing data from at least one surrounding pixel relative to the identified pixel and using the surrounding pixel data to select droplet placement within the identified pixel.

摘要： A computer program product is provided for use with a computer system to execute a simulation. The computer program product includes a plurality of service computer-readable program code means. The service program code means are configured to collectively determine simulated attributes of objects of an environment under simulated operation. Each service program code means is associated with at least a subset of object attributes in an object context. At least some of the service program code means include attribute accessing computer-readable program code means coupling the service program code means to the attributes in the object context for intercommunication there between and for operating upon the object attributes. The intercommunication is based on identifications of the attributes by the service programs that are recognizable by the object context. Mapping computer-readable program code means couple the at least some of the service programs to the object context, for mapping a user-expressed attribute name, not recognizable by the object context, to the identification of the attributes recognizable by the object context.
