PURPOSE: To greatly shorten the time period of prepation as well as reduce the wasting of papers by a method in which initial setting position prepared on the basis of information on pattern and area is finely adjusted, lighting is made in order by an indicator to move the opening degrees by an operating screw and switching operation, and recording is made on a recording medium through a luminous element which can be put on and out.

CONSTITUTION: When a magnetic card 18 is used for initial setting in case where the same printing is again printed the other day, a fine adjustment is again needed. If the adjusting position of a pot screw 12 after the fine adjustment is once recorded on a recording medium, e.g., magnetic card, the needs for fine adjustment for printing following 2nd printing are eliminated. By a pushing switch 50 or 51, LED display is orderly lit or put out from the initial set position, and LED display is matched with the position of the indicator 35 after the fine adjustment. Information on the position of the regulating body after fine adjustment can be stored in RAM by matching LED display of each unit 25 with the position of the indicator 35 after the fine adjustment.
