A page composition method for composing a page from elements in pixelized form for bit-mapping or half-toning prior to printing including; (a) determining the positions of the elements on a printed page; (b) dividing the page into bands; (c) serially transferring pixel data values for sections of bands corresponding to the portions of respective elements in a band, seriatim to a buffer memory, wherein the data from the portion of one element in a band is completely read prior to reading data corresponding to the portion of a second element in the band; (d) writing the data to a buffer memory as it is read; and (e) transferring the data from the buffer memory when all the data corresponding to all portions of all elements in the band is written in the buffer memory.

A color input image comprising a plurality of pixels, each pixels encoded in RGB color space, is processed to convert the RGB pixels to another color space domain for printing the color input image. The number of colors within a cell of the input image is reduced. Each cell comprises an N×M array of pixels and the number of colors is reduced to a maximum of b source colors, wherein b is a positive integer equal to or greater than 2. Each of the resulting colors of each cell is calibrated to generate a printable color. The cells are then processed to convert the pixels of each cell into another color space, for example, to determine ink vectors, in another color space, for each calibrated color.

Color image data is compressed by determining the number of colors within a cell of an input image, each cell comprising an N×M array of pixels; in response to determining that the number of colors is greater than a first predetermined threshold, compress the cell using lossy compression; and in response to determining that the number of colors is less than the first predetermined threshold, reduce the number of colors.

A method for pre-print enhancement of a raster image is disclosed. The method includes receiving the raster image, categorizing an element in the raster image as a graphical element or an image element; and if the element is categorized as a graphical element applying graphical enhancement to the graphical element. A computer program product for pre-print enhancement of a raster image is also disclosed.

An image forming system and a method to order at least two print jobs in a print queue of an image forming system are provided herein. The method ranks the at least two print jobs set in the print queue based on at least one print characteristic. The method resets an order of the at least two print jobs in the print queue based on the rank, such that a first page of a second print job is ordered prior to a last page of a first print job.
