摘要:
A printing sheet is made from a porous resin sheet containing a predetermined amount of carbon grains. In order to manufacture the printing sheet, a mask (which partially shields the infrared rays according to a predetermined pattern) is placed on a transparent plate and the printing sheet is placed on the mask sheet. Flash bulbs irradiate the infrared rays onto the mask sheet. Infrared rays irradiated onto the transparent portion of the mask sheet pass through the mask sheet and reach the printing sheet, causing the carbon grains to heat the resin sheet such that pores in said resin sheet are sealed to form a non-print portion on said porous resin sheet corresponding to said transparent portion.

A stamp apparatus (10) includes a supporting case (11) which supports a printing sheet (1), an ink supply port (17) through which ink is fed to the second surface (1b) of the printing sheet, and a dispersing device (12) provided between the printing sheet and the supporting case. The dispersing device disperses ink supplied from the ink supply port uniformly over the surface of the printing sheet.

A stamp unit 1 in which the circumference of the stamp material 3 is made slant surface 83 by heat-pressing both the lower end 4a of the holder 4 and the circumference of the stamp material 3, and the lower end 4a of the holder 4 is formed in the wedge 82 so as to hook the circumference of the stamp material 3, thereby the stamp material 3 can be surely retained to the holder 4 and the stamp material 3 and the holder 4 can be firmly sealed, as a result, stamping durability is remarkably improved when many stamping operations are repeated.

A stamp unit has a transparent film (91) which protects a stamp surface of the stamp material at the time of transportation of the stamp unit, during storage until a user starts to produce a stamp after purchasing the stamp unit, and during production of the stamp plate. The transparent film is thermally adhered on the lower edge of the holder member (4) and is capable of protecting the surface of the stamp material (73) until the start of the stamp printing. The transparent film is capable of easily and economically adhering to the stamp material without adhering to a thermal adhesion jig.
摘要:
A method for manufacturing a pattern sheet for plate-making capable of easily forming a positive image through the use of a photographic negative film. In this method, as a first step, a negative film with a printed negative image is placed on a surface of a light transmission sheet carrying a photosensitive color-developing layer containing a photosensitive color-developing material which makes a color development in response to light. Further, as a second step, the light is applied thereto from the negative film side after the first step. As a result of the application of the light, a color development takes place in the photosensitive color-developing layer due to the light passing through the negative image, thus causing a positive image to be formed on the surface of the light transmission sheet.
