    摘要： It is checked whether an ink used in a print head has a high density. The type of a printing medium used for a print operation is also identified. An image is printed by scanning the print head once or a plurality of numbers of times. When a print operation is to be performed by using a thick ink, an image is printed by using mask data and the driving frequency of the head which are set for the thick ink. When a print operation is to be performed by using a thin ink, an image is printed by using mask data and the driving frequency of the head which are set for the thin ink and the type of printing medium used for the print operation. Codes of the respective color data of print data are determined in accordance with the types of inks used for a print operation, and an image is printed by printing a plurality of dots or dots in an overlapping state by the multi-pass method.

    摘要： The present invention is to achieve formation of a 2
    n -value image with data of n bits, thereby reducing the amount of image information to be transferred and processed, while improving the tonal rendition, thereby realizing high-quality recording system in the dot matrix recording suitable for personal use. For this purpose there is disclosed an ink jet recording apparatus and a method therefor, comprising an image process unit for generating multi-value information, an identification unit for identifying that the image data are multi-value information, an identification unit for the recording head, and an analysis unit for decoding the n-bit information, and featured by effecting multi-value recording while processing the n-bit data as multi-value information.
