ABSTRACT:
An image recording apparatus is disclosed. An image input device reads in graphic information and outputs the read-in graphic information as multi-tone image data. A pseudo tone generating device reduces the number of tones in the multi-tone image data from the image input device by processing a group of multi-tone image data to produce pseudo tone image data. An image printing device performs printing based on the pseudo tone image data generated by the pseudo tone generating device, the pseudo tone generating device being incorporated in the image printing device. The apparatus can also include an image storage device, for temporarily storing the pseudo tone image data generated by the pseudo tone generating device. The image printing device prints the pseudo tone image data stored in the image storage device.
