摘要： An ink jet printer apparatus and method includes a print head having at least one nozzle. In response to a signal related to media type that is to be recorded upon, gray level image data relating to at least three different drop volumes including no ink drop are recorded at different pixel locations to form dots of different dot size or dot density on the recording medium. In recording image data of the same multitone image data value on different media, drop volumes deposited on one medium by the nozzle are different than drop volumes deposited on another medium by that nozzle. In some embodiments or printing modes image data is also recorded by depositing a variable size dot on a reference raster location and a supplementary dot at an adjacent pixel location on a shifted raster.

摘要： An ink jet print head includes an array of nozzles, each nozzle being capable of selectively producing when actuated at least two ink drop sizes including a larger ink drop size and a smaller ink drop size. In response to a pixel density signal of maximum density value at a respective pixel location, a nozzle prints a drop of the larger ink drop size at the respective pixel location on a reference raster and the same or a different nozzle prints a drop of a smaller drop size at a pixel location adjacent to the respective pixel location on a shifted raster to provide for full coverage with improved dry time capability of the printed ink drops.

摘要： An ink jet printer apparatus and method of printing wherein image data representing a predetermined number of gray levels of pixels to be printed are accommodated in an inkjet printer for recording on a receiver medium. The printer has the capability of producing fewer numbers of gray levels at respective pixel positions than the data requires. The inkjet printer prints an increased number of the gray levels by applying multitone printing to pixels locations on a reference raster and provides supplementary ink drops to respective adjacent pixel locations on a shifted raster.

摘要： Digital ink jet printing apparatus and method. The apparatus receives an input image file having a plurality of pixels, each pixel described by at least one pixel value respectively associated with an optical density. The apparatus comprises a printhead and at least one nozzle integrally attached to the printhead, the nozzle being capable of ejecting an ink droplet therefrom to define an associated one of the optical densities. A waveform generator is connected to the nozzle for generating an electronic waveform to be supplied to the nozzle. In this manner, the nozzle ejects the ink droplet in response to the waveform supplied thereto. The waveform is defined by a plurality of pulses. A look-up table stores a plurality of waveform serial numbers assigned to respective waveforms, each waveform being defined by at least one predetermined parameter, such as number of pulses, pulse amplitude, pulse width and/or time delay between pulses. A calibrator receiving the input image converts the pixel values of the input image to waveform index number associated with the waveform serial number.

摘要： A digital halftone image is produced by providing a binary bit image pattern having a minimum visual noise for each density level in an image. The patterns are produced by employing a stochastic combinatorial minimization technique and a human visual system modulation transfer function (MTF) weighting function to generate a halftone pattern for each density level of the multi-level digital image signal. A halftone image is produced by modularly addressing these patterns with each pixel value in the image.
