A stencil printing machine is provided as including first and second printing drums and carrying thereon respective screens , a press drum located in close proximity to the printing drums and a stencil making unit . In a control method, the stencil making unit supplies a perforated stencil sheet onto a selected printing drum and a non-perforated stencil sheet onto a non-selected printing drum , wherein a print sheet clamped to the press drum is transferred along an outer periphery of the press drum to allow the perforated stencil sheet of the first printing drum to transfer printing ink with a first color to the print sheet while the non-perforated stencil sheet mounted onto the second printing drum prevents printing ink to be transferred to the print sheet
