The method of the invention converts colors resident in a first device color space to gray levels for reproduction by a single color marking media in a color or monochrome rendering device. The method converts a set of red, green and blue (RGB) primary color values received from a processor to gray level values. The method applies a gamma correction function to the RGB primary color values and further scales the values to a range of from 0 to 1. The method then converts the gamma-corrected and scaled RGB primary color values to a Y luminance value (in the XYZ tristimulus color space) through use of the expression: where: Y , Y , and Y are coefficients that provide a luminance value in the XYZ color space in accordance with accepted observer standards; k is a correction value that renders the green component darker; and k is a correction value that renders lighter the blue component. The resulting luminance value is then converted to a device gray value and stored in a table for later use.

A peripheral unit converts an input data flow to page-arranged outputs and includes a random access memory capacity that is insufficient in size to accommodate an entire page of raster data. The peripheral unit also includes a processor and a control memory that holds a plurality of data compression procedures, each procedure exhibiting a different performance characteristic. The peripheral unit performs a method for compressing portions of the input data flow that includes the steps of: allocating the random access memory to portions of the input data flow; determining when an insufficient amount of random access memory is available for such allocation; employing a first data compression procedure on the input data flow portions to produce a compressed data portion; testing the compressed data portion to determine if a level of compression has been achieved that exceeds a threshold and, if not, employing succeeding data compression procedures and repeating the test for each procedure against a threshold, whereby the compression procedure that first enables a threshold level of compression to be achieved is the compression procedure employed to compress the data flow portion. Improved compression methods and techniques for handling input data flows with both integral and independent image descriptors are also described.

A method of calibrating a printing device includes storing current calibration data in the printing device; and modifying each incoming print job using the calibration data stored in the printing device. A printing device having a calibration function includes a memory storing current calibration data in the printing device; and an operator, executed by the printing device, configured to modify each incoming print job using the calibration data stored in the printing device.

A method of gray scale printing of dots of one or more colors into pixels and in a controlled ordered sequence into a plurality of super pixels defined by a given number of said pixels, characterized in that: one or more levels of dot loading are used to achieve different values of gray level in a multiple-level gray table. This generic method is applicable to both ink jet and electrophotographic printing species of this invention. In one electrophotograpic printing species of this invention, there is disclosed a method of electrophotographic color printing which includes mixing a plurality of colors in a single plane and in dot-next-to-dot (DND) pixels within a plurality of super pixels to produce a color image, whereby the sum of the multi-color dots printed in any super pixel is limited to the number of subdivided individual pixels therein, thereby assuring dot-next-to-dot (DND) always printing of said colors in a single plane. The above method further includes varying the area of each printed color dot within each pixel of a super pixel in order to control the gray scale of a printed color image. Gray scale printing is achieved by controlling the selection of a gray table entry level number representative of one of several available entry level numbers corresponding to a plurality of different dot loadings for a corresponding plurality of differently printed super pixels.

358298

A method for reducing "grainyness" or color contrast in color imaging systems and simultaneously reducing or eliminating paper cockleing of media printed by ink jet printing. The method involves determining the maximum allowable ink print density necessary to reduce or eliminate paper cockleing in the printed media and then providing tight control of the selection of gray scale ink drop count and associated dye loading in relation to this maximum allowable print density. Using this method, pixels are selected and printed in such a manner as to maximize the uniformity of ink distribution on the printed media. This method will work using either a variable drop size or a fixed drop size with variable dye loadings. It will also work with most error diffusion or dithering schemes presently used and available in the image processing arts.

Text and line art image data is distinguished from halftone image data for selectively enhanced rendering thereof. Specifically, a method of rendering a raster pixel image from a stored bitmap includes (i) determining whether an orphan pixel is detected within a bounded sampling window of the bitmap, and, (ii) processing at least one selected pixel of the bitmap within the sampling window relative to the determining of whether an orphan pixel is detected. In general, an orphan pixel is defined as an isolated white or black pixel in a halftone image. In one embodiment, an orphan pixel is recognized as having a predefined pixel value and as having no other pixels with that value adjacent thereto within the sampling window. In the event an orphan pixel is detected within the window, then the bitmap within the window is determined to be halftone image data and the selected pixel is processed accordingly. In the event an orphan pixel does not exist within the window, then the bitmap within the window is recognized as text or line art image data and processed respectively.

A multichamber ink jet pen has a printhead comprising a plurality of nozzle groups corresponding in number to the number of chambers. The nozzle groups are respectively in communication with the individual chambers for receiving ink. The multi-color ink jet pen is retrofittable in a single color printer to provide multicolor printing capability. The nozzles in the nozzle groups are formatted to correspond to the nozzle format in the printhead of the single color ink jet pen, including the same nozzle spacing, to take advantage of the single color printer control for that nozzle format. The nozzle groups each duplicate a different longitudinal segment of the single color nozzle column pattern. The nozzle groups are staggered in the scan direction and the end nozzles in the respective groups have the same longitudinal spacing therebetween as the nozzles in the nozzle columns to duplicate the nozzle spacing of the single color nozzle column pattern within and between the nozzle groups of the multi-color recording head.
