A check pattern for a registration adjustment under low resolution condition of 600 dpi x 600 dpi at substantially central portion of a printing medium is printed. After performing the registration adjustment based on the printed pattern, the check pattern is printed under high resolution condition of 1200 dpi x 600 dpi at a position not causing interference with the former check pattern. On a basis of this, the registration adjustment is again performed. By this, the registration adjustment in high precision printing can be performed easily. Also, necessary two check patterns can be printed on a single printing medium to permit lowering of cost concerning printing medium to be used in check pattern printing. <IMAGE> |
