Abstract: Offline proofing systems and methods for color image processing may include receiving a digitized image document to be press printed in a job, determining job status as corresponding to one of a color managed proof and a color managed press, installing a proofer profile as an output profile and a press profile as a simulation profile in response to the job status corresponding to the color managed proof, printing the job by the proof printer as a proof copy in response to the color managed proof, installing the press profile as an output profile and discarding the simulation profile in response to the job status corresponding to the color managed press, and printing the job by the press printer as a press copy in response to the color managed press. The color managed press may be based on a customer contract approval. The proofer profile may correspond to a proof printer and the press profile may correspond to a press printer.
Abstract: An image forming apparatus includes an image carrier, a rotary developer unit having a developing roll opposed to the image carrier when located at a developing position and an exposure device for writing a latent image onto the image carrier, wherein an optical path from the exposure device to the image carrier passes within a circumscribed circle of the developing roll with the center of rotation of the rotary developer unit as the center of the circle. The image carrier is located so as to provide the developing position above a horizontal line passing the center of rotation of the rotary developer unit, and the exposure device is located so as to provide a beam exit position below the horizontal line.
Abstract: A vent connects a chamber to the external atmosphere surrounding a device to equalize pressure within the chamber. The vent has a size and shape to allow pressure equalization to occur outside a normal operating cycle of the chamber and controls the pressure to prevent undesirable deflection of a membrane within the chamber and ensure proper operation of the device.

Abstract: An original comprises a first page and a second page as disposed face-down on the platen surface of an image-processing device. The platen is scanned to form a platen image. The positions of two diagonally-opposite corners of the original are determined based on a fixed platen reference point. An original image is formed by cropping the platen image based on the positions of the two original corners. The size and position of either one selected page or both pages are determined based on the two original corner positions. When the image of only one selected page is desired, the image of the selected page is formed by cropping the original image based on the size and position of the selected page. When the images of both pages are desired, the images of both pages are formed by cropping the original image based on the sizes and positions of both pages.
Abstract: Optimal rehalftone screen frequencies are found by searching frequency space for points that are maximally spaced from significant frequency components of an input image halftone screen or screens. Selecting a rehalftone screen having a maximally spaced frequency produces moiré of the highest frequency possible. High frequency moiré are visually unobjectionable. Optimal rehalftone frequencies may be found near the maximally spaced points where system or other constraints limit the usefulness of the maximally spaced points. Rehalftone screen frequencies in the range of about 1.4 to about 1.8 times the fundamental frequency of the input image halftone screen are often optimal. A rehalftone screen frequency of 1.5 times the fundamental frequency of the input image halftone screen is often optimal when the input image is monochrome and uses a dot screen.

Abstract: A printing system for use in printing objects of any of a plurality of different object types includes a printer; and a printer control device with a user interface having a first option for associating printer-independent print-quality characteristics with a selected object type to be printed by the printer. A printer-independent print-quality characteristic is an instruction associated with an element, such as object type, in an electronic page which indicates printer-independent features that are preferentially emphasized when printing the element. Examples of printer-independent print quality characteristics include “make sharp edges”, “reduce mottle”, “distinguish neighboring colors”, “reduce moiré”, “distinguish tone and edges”, “maximum tone depth”, “perceptual colors” and “compress without loss of detail”.

Abstract: In a xenographic printing apparatus, a small footprint charging device may provide uniformity of charge and/or long life in a small diameter photoconductive drum. A grid shaped to be parallel to the drum surface and including small wing shields may reduce or even prevent leakage of corona current to the photoconductor around the grid region, which may otherwise detract from charge uniformity.
Abstract: Defects in an image may give rise to visible streaks, or one-dimensional defects in an image that run parallel to the process direction. One known method for compensating for streaks introduces a separate tone reproduction curve for each pixel column in the process direction. A compensation pattern according to this invention ha alignment marks before and after a halftone compensation region. The alignment marks provide alignment between the printer pixel grid and a scanning pixel grid. The line width of each alignment mark and the gray level in each pixel column of each gray level portion is measured and analyzed to produce a local tone reproduction curve for each pixel column and associated line width. The line widths of the alignment marks can be remeasured to adjust the local tone reproduction curves to compensate for the streak defect when printing.
