【発明が解決しようとする課題】押圧式の孔版印刷装置
に於いて所定濃度の孔版印刷を行うためには、所定の印
刷押圧力が必要であり、これは印刷面が大きいほど大き
くなる。In order to perform stencil printing at a predetermined density in a press-type stencil printing apparatus, a predetermined printing pressing force is required, and the larger the printing surface, the greater the pressing force.
【0006】これに対し上述の如き孔版印刷装置に於い
ては、孔版原紙を印刷用紙載置台上の印刷用紙を押し付
ける印刷押圧力は手による押圧板の押し下げ回動操作に
より得られるから、これには自ずと限度がある。On the other hand, in the stencil printing apparatus as described above, the printing pressing force for pressing the stencil sheet against the printing paper on the printing paper mounting table can be obtained by manually pressing and rotating the pressing plate. Is naturally limited.

印刷が行われなくなる。In order to perform stencil printing with a uniform density,
It is necessary that the printing pressing force acts uniformly on the entire printing surface. However, in the stencil printing apparatus as described above, the pressing plate is of a rotary type, and the pressing operation force of pressing down the pressing plate is directly applied. By acting on the printing surface as a printing pressure,
The printing pressure acting on the printing surface tends to be non-uniform, and it is difficult to obtain a stencil image with excellent print density uniformity. This becomes more remarkable as the printing surface becomes larger, and a stencil image having a uniform density cannot be obtained, and practical stencil printing cannot be performed.
【0008】このようなことから、上述の如き孔版印刷
装置に於いて実用的な孔版印刷の用紙サイズはせいぜい
B5〜A4判程度である。For these reasons, in the stencil printing apparatus as described above, the practical stencil printing paper size is at most about B5 to A4 size.

けの多色印刷が行われなくなる。In the above-described stencil printing apparatus,
Since the pressing force acts in the penetrating direction on the printing ink layer applied to the stencil paper, the pressing force acts on the printing ink for the stencil printing even if the printing ink is applied only to a part of the stencil paper. Each time the printing ink layer expands and expands, the amount of wasted printing ink increases. This is known as
In the case where multicolor printing is performed using a stencil sheet on which printing inks of each color having a hardness capable of self-holding the shape as disclosed in JP 3601 are placed as ink masses, this case is wasteful. In addition to an increase in the amount of printing ink, if the number of prints is large, the printing ink of each color will be mixed due to the expansion and expansion of the printing ink mass of each color, and multicolor printing with appropriate color classification will not be performed.

い。[0010] The above-mentioned suction-type printing apparatus exerts a suction effect on the surface of the pattern screen on the side of the printing material through a member corresponding to the printing material (fabric), so that the printing material has air permeability like cloth. And cannot be diverted to a stencil printing apparatus for printing on ordinary printing paper or the like. In addition, the suction-type printing apparatus as described above applies the suction force from the suction holes of the perforated support or the mesh of the mesh plate directly to the surface of the pattern screen on the printing material side through the printing material, and the movement of the suction force is controlled. Since the dye on the paper pattern screen is sucked into the printing material through the opening of the paper pattern screen by pressure action, the paper pattern screen has an intensity distribution according to the suction hole pattern of the perforated support or the mesh pattern of the mesh plate. The suction force acts, and the suction force does not uniformly act on the entire surface of the pattern screen. For this reason, even if the printing paper has some air permeability, a printed image having a uniform density cannot be obtained unlike fabric.

粘着層より剥離することが難しくなる。When the stencil sheet is separated from the printing paper on the printing paper mounting table when printing is completed, the printing on the printing paper mounting table is performed so that the printing paper remains on the printing paper mounting table against the viscosity of the printing ink. It has been conventional to provide an adhesive layer for holding the printing paper on the paper mounting surface.However, if the printing surface is large, the size of the printing paper also increases, and the printing paper resists the viscosity of the printing ink. It is also difficult to separate the printing paper from the stencil sheet so that the printing paper remains on the printing paper mounting table. If the adhesion holding force of the printing paper by the adhesive layer is increased so that this is surely performed, it becomes difficult to peel the printing paper adhesively held by the adhesive layer from the adhesive layer without being damaged.

Even if the printing surface is large, stencil printing with a predetermined density and uniform density can be easily and simply performed. It can be done quickly and multi-color printing can be performed with proper color classification even if the number of prints is large,
In addition, it is an object of the present invention to provide a stencil printing apparatus that can hold and remove printing paper on a printing paper mounting table in a satisfactory manner.

行われる。Therefore, in printing, first, a negative pressure is applied to the air suction holes to cause the printing paper on the printing paper mounting surface to be attracted to the printing paper mounting surface and fixed to the suction-type printing paper mounting table. Is placed as a mass of ink on the stencil paper, and the pressure chamber is depressurized by the decompression means. As a result, a differential pressure acts on both sides of the diaphragm in a substantially stationary fluid atmosphere in a static pressure manner, so that the diaphragm wraps the ink mass on the ink mass on the stencil sheet according to the surface shape of the ink mass. The stencil paper is pressed by the diaphragm and closely adheres to the printing paper on the printing paper mounting surface, and in this state the ink mass on the stencil paper is caused by the differential pressure that acts uniformly on the entire surface of the printing paper. Stencil printing is performed on the printing surface of the printing paper by uniformly pressing the printing paper according to Pascal's law in a fluid pressure manner.

The stencil sheet and the printing paper are peeled off in a state where the stencil sheet is absorbed and absorbed. By returning the air suction hole to the atmospheric pressure after the stencil sheet is separated, the suction holding of the printing paper on the printing paper mounting surface is released.
