ABSTRACT:
The invention seeks to reduce amount of image data without detracting from picture quality, thereby lowering processing speed and holding down memory cost. While preserving the density of color image data, a computer compresses the color image data, which has been outputted by an image scanner, to a prescribed number of colors on the basis of the colors of inks. An image processor binarizes the results of compression, while preserving density, on the basis of ink colors. A main unit repeatedly prints a basic image, which is represented by the binarized image data, on cloth supplied from a supply unit.
