In a stencil printing in which a perforated stencil sheet is wound around a circumferential surface of a printing drum to which an ink is supplied, and the ink is transferred from the printing drum to a printing sheet through the perforated stencil sheet by pressing the printing sheet to the printing drum while the drum is rotated, a method for controlling a printing density is provided, which comprises controlling an amount of an ink transferred to a printing sheet by selecting a specific value of D from a range predetermined in accordance with the following equation:D= 2ROOT +E,rad +EE (F/f)in which F is a possible range of pressing force at which the printing sheet is pressed to the drum, and f is a possible range of rotation speed of the drum. Also provided is a printing density controlling device for stencil printing which comprises a means for setting a specific value of D within a range predetermined in accordance with the equation above, whereby an amount of the ink transferred to the printing sheet is controlled. A computer program storage medium is also provided which contains a program for controlling a printing density in stencil printing, in which the program calculates a range of f at a selected value of D or a range of D at a selected value of f, in accordance with the equation above.
