    摘要： What is disclosed is a novel system and method for reducing a size of a memory buffer used by an electronic registration correction system performing an electronic registration correction on a digital image. The present method uses column address segmentation to identify blocks of scanlines within a spatially mapped array of image pixels comprising a digital image. Advantageously, the present system and method reduces scanline buffer memory by a factor of 2n-1, where n is the number of column address segments. Buffering can be performed at almost any upstream location in the image path. The present method is well suited for high resolution imaging equipment where memory is constrained by design, cost, or space limitations.

    摘要： A method of operating a printer enables printheads mounted on print bars to be operated to compensate for misalignment of printheads in the process direction. The method includes identifying a position in the process direction for each printhead in a plurality of printheads, selecting one of the identified printhead positions as a reference printhead position, identifying a printhead timing parameter for each printhead mounted to at least one print bar, generating a firing signal for the printheads mounted to the at least one print bar, and adjusting delivery of the firing signal by the identified printhead timing parameter for each corresponding printhead mounted to the at least one print bar to coordinate actuation of inkjet ejectors in the printheads mounted to the at least one print bar and compensate for misalignment of the printheads in the process direction.

    摘要： Sub-raster registration errors are compensated for through non-redundant overwriting. Data from adjacent rasters is written to a particular output raster so that the adjacent rasters share an influence at a point actually written to by a rendering device, thereby compensating for a sub-raster component of a registration error associated with writing to the particular point. If two writing passes per raster are used and the writing passes have equal influence (e.g., are written with equal power), then writing data from a first raster during a first pass and writing data from a second raster adjacent to the first raster during a second pass compensates for a sub-raster registration error of half a raster spacing. If two writing passes are associated with different influence (e.g., are written with ⅓ and ⅔ power respectively) and/or if additional writing passes are used, then addition sub-raster positions can be compensated for or emulated.

    摘要： An apparatus (100) and method (200) that determines beam delays in a printing device is disclosed. The apparatus can include a photosensitive surface (110) and a raster output scanner (120) optically coupled to the photosensitive surface. The raster output scanner can include a first optical emitter (121) configured to scan a first beam across the photosensitive surface and at least one second optical emitter (122) configured to scan a second beam across the photosensitive surface to form an image on the photosensitive surface. The apparatus can include an integrated scan detector (130) configured to detect the beams from the raster output scanner and configured to produce a signal based on the beams detected from the raster output scanner. The apparatus can include a beam calibration controller (140) coupled to the integrated scan detector. The beam calibration controller can be configured to determine at least one beam delay between the first optical emitter and the at least one second optical emitter based on signals from the integrated scan detector. The beam calibration controller can be configured to delay operation between the first optical emitter and the at least one second optical emitter based on the at least one beam delay.

    摘要： A method enables linear web velocities generated with reference to angular velocity signals generated by encoders at different rollers in a double reflex printing registration system to be equalized. The method includes identifying a low frequency component of a first linear velocity of a moving web, identifying a high frequency component of a second linear velocity of the moving web, and computing a linear velocity for the moving web at a roller in a print zone with reference to the identified high frequency component of the second linear velocity and the identified low frequency component of the first linear velocity.
