PROBLEM TO BE SOLVED: To improve a printing quality of images including figures, characters and the like by judging the presence/absence of dot formation based on pixel gradation values, reloading the judge result so as to form small dots for outline pixels, and forming dots of each size. SOLUTION: The printing apparatus has a color scanner 21 and a color printer 20 connected to a computer 80. A predetermined program is loaded to the computer 80, whereby printing is executed. A color original is converted by the color scanner 21 to color image data recognizable by the computer 80, and then input to the computer 80. The computer 80 converts the color image data to data printable by the printer and outputs to the color printer 20. The conversion result of the image data is output as the image data printable by the printer to the color printer 20. The color printer 20 forms ink dots of each color on printing papers. A quality of print images can be improved accordingly. |
