    摘要: An ionographic printer directs a stream of ions from a source to a charge receptor to create an electrostatic latent image thereon. The ion stream passes through a relatively large aperture having associated therewith a pinch electrode for narrowing the ion stream to a preselected width, and displacing electrodes for positioning the narrowed ion stream within the aperture. Varying the biases of the displacing electrodes causes the ion stream to scan across the aperture to deposit multiple spots of charged areas at desired locations on the receptor. The electrodes can be designed to compensate for spot placement skew and anomalies in the cross-sectional shape of the displaced ion stream.

    摘要: In a digital printer, method and apparatus for formatting printer control signals. According to the invention, characters to be printed are stored in ASCII format in the memory of a microprocessor system. Successive characters are formatted into an on/off bit mapping where a bit signal corresponds to a blank region and a bit signal corresponds to a darkened region. Eight bit slices of the characters are formatted until an entire print width is completed and stored in an 8 bit.times.N buffer where N varies with the desired printer resolution. In the preferred embodiment two buffers are used so that while the contents of one buffer are used to control the printer the second buffer can be bit formatted under microprocessor control.

    摘要: A system for processing halftone image data in digital format. The image data is electronically screened to provide a binary output suitable for storage or printing, the image data being processed in discrete blocks or cells. The error between actual and printed average gray values of each image cell processed is determined and the electronic screen thresholds are modified in accordance with such error (if any) prior to processing the next image cell. At the beginning of the aforesaid process and at the beginning of the processing each line, an error is randomly chosen.

    摘要: A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.

    摘要: A technique for cross-channel correction in real time for digital color printing in which the full resolution value of a selected colorant is combined with low resolution versions of the remaining colorants to provide a basis for correcting the selected colorant based upon the data for the other colorants employed. The pixel values of sub-samples of the remaining colorants are derived from the cell in which the full resolution selected colorant is taken; and, the desired output value is selected from a look-up table established for the known printing process.
