摘要： An image preprocessor is disclosed for a DEP device, wherein the image preprocessor corrects digital image data before printing.
The image pre-processor preferably performs at least one the following steps :

1. correcting the image input density according to a first look up table (LUT) for obtaining a desired grey scale value,
2. correcting grey scale values by a second LUT for varying toner fluxes 111 through different printing apertures 107, said second LUT being desirable for adjusting the toner flux 111 to the differing distance of printing apertures 107 belonging to different rows of apertures 107, and for adjusting the toner flux 111 through various printing apertures 107 having varying aperture diameter or shape. This is referred to as a shading correction in a direction orthogonal to the print direction),
3. correcting grey scale value for the grey scale values of neighbouring pixels, that influence the toner flux 111 for forming the actual image pixel, referred to as neighbour compensation,
4. correcting grey scale values for the image density that has been printed through the individual printing aperture 107 prior to the actual printing the required pixel, called previous compensation,
5. correcting grey scale values for the hardware design of the printhead structure 106, i.e. assignment of image pixels to controlling IC number and output channel number per IC,
6. expressing grey scale values as a time modulated or voltage modulated output signal,
7. transferring image output signals in a serial data stream to a FIFO memory from which the output signals are preferably converted to a parallel data stream that is fed to driving IC's, that are used to put a voltage to the individual control electrodes 106a of the printhead structure 106 in the DEP device 100.

摘要： A color proofing system (10) effectively produces off-press proofs for gravure printed images using a high resolution electrophotographic printer by optimizing the deposition profile of a clustered dot cell of electrophotographically developed ink dots so as to more closely simulate the deposition profile of ink deposited in conventional and direct transfer (halftone) gravure printing processes. The three operating parameters of the electrophotographic process that are selectively modified during this process to produce are: (1) the spot image overlap of the laser beam profile; (2) the charge differentiation between the non-charged and charged areas on the photoconductor; and (3) the charge density associated with the toner particles deposited on the photoconductor surface. The gravure dot cells produced by this process can vary in both cell area and ink thickness. The resulting variation in ink thickness, graduated edge profile, and overlapping of adjacent gravure dot cells allows the ink deposited on top of a paper substrate by the electrophotographic process to more closely simulate the color and tone reproduction of ink that is absorbed into the paper in a gravure press printing. Thus, the tonal rendition of the finished off-press proof more accurately simulates gravure printing than any previously known gravure proofing process.

摘要： This invention is directed to a removal of a ghost image created during a processing of a film laminate medium (12′) by an electrographic plotter (10′). Recording an image on the film medium induces a ghosting potential over a developing station (30) which causes a spurious image (ghost) to be developed.
The latent image is created by depositing a charge on a dielectric layer of the film. A relationship exists between the deposited charge and the ghosting potential. By use of information known to the system, the ghosting potential may be estimated and reduced. A preferred method estimates the magnitude of the ghosting potential by use of the relationship between deposited charge and ghosting potential. A counteracting potential is applied to the system to reduce the ghosting potential over the developing station.

摘要： A dual mode laser printer utilizes a program-controlled microprocessor to switch between a high resolution, slow speed mode and a low resolution, high speed mode. In the printer a laser beam is modulated at a rate which is a first division of a system clock rate. This beam is caused to focus on a recording medium and, due to a rotating multi-faceted polygon, the beam sweeps across the medium. The medium is moved according to a second division of the system clock. By means of the microprocessor, the printer can be in either: (1) the high resolution mode in which the laser beam is modulated at a high rate due to the first divided signal and the medium moves at a slow rate due to the second divided signal, or (2) the low resolution mode in which the light beam is modulated at a lower rate due to the first divided signal and the medium moves at a faster rate due to the second divided signal.
