摘要： An ink jet printing method and apparatus using a color ink and a print performance improving ink which minimizes an image quality degradation due to blank lines formed by failed or faulty nozzles. This system enables the use of a print head even with failed or faulty nozzles by minimizing the image quality degradation and extends the life of the print head before replacement. The print performance improving ink is not ejected and landed near a blank line, thus allowing the color ink dots near the blank line to spread and thereby making the blank line undistinguishable.

摘要： A recording apparatus includes a recording head for performing recording on recording paper, the recording head having three or more types of inks of different densities but of the same color. A combination of the inks used to record a pixel of a grayscale image, which is to be recorded on the recording paper, is decided based upon the pixel by a data distribution unit which refers to ink density data and combination data. Recording by the recording head is controlled, based upon the combination of inks decided, by a unit which controls the recording head and paper feed.

摘要： An ink jet printing method and apparatus using a color ink and a print performance improving ink which minimizes an image quality degradation due to blank lines formed by failed or faulty nozzles. This system enables the use of a print head even with failed or faulty nozzles by minimizing the image quality degradation and extends the life of the print head before replacement. The print performance improving ink is deliberately ejected onto a blank line or its vicinity to produce the so-called primer effect, thereby inducing the color ink dots on the lines adjoining the non-ejecting nozzle line to spread into the blank line to make the blank line undistinguishable.

摘要： In an image printed by a printing apparatus, graininess particularly in a light part of the printed image is reduced by relatively simple structure by using a second color. To do so, magenta and cyan color component data in image data is subjected to under color removal to generate image data of a blue ink being the secondary color. On the basis of the data of the blue ink replaced for magenta and cyan, printing is performed by forming dots of the blue ink. At this time, black data is distributed into dark black and light black by density distribution, and the light black is substituted by the blue and yellow inks, whereby it is possible by the simple structure to prevent the graininess appeared when the cyan and magenta dots mutually appear biasedly and the graininess due to the black ink dots.
