Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive system with automatic feed-on and feed-off operations to minimize labor overhead to satisfy needs of small print shops.SOLUTION: A media feeding and cutting system 10 includes: a media cutter 16 including a cutting surface and a digital cutting device; a first feeder 14 configured to automatically transport individual sheets of media from an in-feed receptacle 12 toward the cutter; a positioner configured to position the medium on the cutting surface; a second feeder 18 disposed adjacent to or connected to the cutting surface which is configured to automatically transport the cut medium from the cutter to an out-feed receptacle; and a processor configured to operate the cutter, first feeder, positioner and second feeder.
Abstract:
PROBLEM TO BE SOLVED: To provide a system which copes with errors of the velocity and the position of a linear web. SOLUTION: A double reflective printing alignment system includes a first converter which is constituted to create a first linear velocity regarding the moving web in a first roller, a second converter which is constituted to create a second linear velocity regarding the moving web in a second roller, a low pass filter which specifies the low frequency of the first linear velocity in combination with the first converter, a high pass filter which specifies the high frequency of the second linear velocity in combination with the second converter, and a controller which is constituted to calculate the linear velocity of the moving web in the second roller by referring to the specified high frequency component of the second linear velocity and the specified low frequency component of the first linear velocity.

Abstract:
PROBLEM TO BE SOLVED: To address the effect of web changes and environmental conditions during operation of a web printing system on registration.SOLUTION: A method of operating a printer enables compensation parameters to be generated and stored in association with system conditions detected at the time of the compensation parameter generation. Upon detection of corresponding system conditions at a later time, the printer is able to use the previously generated and stored compensation parameters to adjust the timing of printhead ejections to improve the registration in ink images formed by the system.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of achieving process-direction sub-raster magnification adjustment using non-redundant overwriting. SOLUTION: The method of achieving process-direction sub-raster magnification correction using non-redundant overwriting includes determining process-direction magnification errors on both sides of a printed sheet and a magnification correction factor for the printed sheet (101), receiving raster data from a digital image path and buffering the raster data in a raster memory for overwriting a swath of pixel data (102), extracting the raster data from a buffer according to a plurality of non-redundant overwriting (NRO) resampling calculations for magnification correction (103), and using the extracted raster data to drive a raster imager.
