摘要： A method and apparatus of printing with a liquid ink printhead ejecting ink in swaths on a recording medium to form an image including a plurality of dots deposited at pixel locations of a scanline. The printer deposits a plurality of dots at adjacent pixel locations on the scan line during non-consecutive swaths of the printhead to form the image. Dot interaction between dots is minimized so that no two dots are deposited adjacent to each other in consecutive depositions of the dots of consecutive swaths of the printhead. Reduction of ink bleeding, printhead signatures such as banding, and other defects caused by clogged nozzles of the printhead are reduced.

摘要： A method for converting a set of input image pixels having a first resolution and being represented by a set of input image signals to a set of output image pixels having a second resolution and being represented by a set of output image signals. The method is adapted for use in an electroreprographic machine having a memory for storing images and an image output terminal for printing the images. The method comprises the following steps: first, developing a set of state determination rules which govern the conversion of the set of input image pixels having the first resolution to the set of output image pixels having the second resolution; second, communicating the set of input image signals and the set output image signals to the memory, third, relating a plurality of selected input image pixels with a selected one of the output image pixels; fourth, determining respective binary states of the plurality of selected input image pixels; finally, corresponding the selected output image pixel with one of at least three output states by reference to the determined, respective binary states and one of the state determination rules.

摘要： A method for improving the quality of bitmap image includes repeated iterations of doubling the resolution of an image and smoothing the doubled image. The doubling and smoothing steps are repeated until the intermediate image has a resolution which is greater than a desired resolution of an output image. After generating such an intermediate resolution image, the intermediate resolution image has its resolution reduced to the desired resolution by area mapping to generate a pseudo-gray scale image. The pseudo-gray image is then further processed to further improve the image quality, and then is converted to a true gray scale image or a binary image having the desired resolution.
