<p>A printing apparatus is provided, which comprises an ink-permeable cylindrical printing drum (5) which is rotated about the axis of rotation thereof with heat-sensitive stencil sheet (13) wound around the circumferential surface thereof; a liquid ejecting means (25) which ejects a photothermal conversion material contained in a liquid (26) to heat-sensitive stencil sheet in accordance with image information, so that the photothermal conversion material is transferred to the stencil sheet as a reproduction of the image; a light radiating means (30) which radiates a visible or infrared ray (31) to the stencil sheet to which the photothermal conversion material has been transferred, so that the stencil sheet is perforated by heat emitted by the photothermal conversion material; and a pressing means (6) which presses at least either said printing drum or printing sheet that is being moved synchronously with rotation of the printing drum, to bring them into close contact with each other, so that stencil printing ink that is fed in the printing drum is transferred to the printing sheet through the stencil sheet perforated, in which said liquid ejecting means is further capable of ejecting a photothermal conversion material and/or a colorant contained in a liquid directly to printing sheet in accordance with the image information, so that the image can be reproduced directly on the printing sheet. Printing can be effected in two modes of stencil printing and printing directly from the liquid ejecting means. Upon perforation, stencil sheet is not required to contact any substance such as an original or a thermal printer head. <IMAGE></p> |
