PROBLEM TO BE SOLVED: To enhance an efficiency of aligning by setting and storing mark positions, deviations and a plurality of allowable values of a material to be treated and a screen according to a type of the material as a calculated results of the deviations of the material and the screen, comparing the deviations with the allowable values, and deciding an aligning result. SOLUTION: In the case of seeing, for example, from a final product, a base A with a sufficient allowed value A takes a time a as an aligning time, and a base B decided with a sufficient allowed value B and sufficient with further lower accuracy takes a sufficient aligning time b. Thus, the aligning time can be shortened, and a printing tact time can be shortened. Thus, since an operator sets the allowed value of the aligning accuracy to each type of the base to be printed and stores it in a base print information unit. At the time of aligning, the value is compared with that of the corresponding information unit, an optimum time responsive to the base can be set, and the printing tact tank can be optimized according to the base. |
