構成になっている。2. Description of the Related Art A dry offset planographic plate that utilizes the ink repellency of silicone rubber, fluorine compounds, etc. is known as a printing plate for performing planographic printing without supplying dampening water. The printing method is such that the non-image areas are made of an ink-resistant material so that ink is selectively applied only to the image areas without using dampening water. Silicone resin is mainly used as the ink-resistant material. The silicone resin in the image area is removed using electrical discharge destruction,
A method is known in which ink is placed on the image area and transferred to the printing material. (Japanese Patent Publication No. 52-30857) The printing medium used in this method has a conductive layer on one side of an ink-receiving support that can be partially removed by discharge destruction.
Furthermore, the structure is such that an insulating layer having ink resistance is provided on the upper surface thereof.

The equipment for this was a huge waste and it was difficult to make it smaller. Furthermore, since the ink dries, cleaning after use is essential, and it cannot be easily used as a facsimile or printer.

Print media 2 in Figure 0 is pulled out through 06 as shown in the figure.
The ink surface of 01 is on the outside of the take-up bobbin 202,
The ink-resistant I8 layer on the front side of the print medium drawn out from the zero-winding bobbin 202, which is depicted by a thick line, is destroyed by the recording head 208 in accordance with the electrical signal from the electrical signal source 210. A platen 209 presses the print medium against the recording head to improve contact. Thereafter, the printing medium is pressed against the ink on the back surface of the printing medium at the roller 205, and the ink is adhered to the image area where the ink anti-fa layer has been destroyed.

塗布した。Example 1 Aluminum was vacuum-deposited on one side of a 25 μm polyester film to a thickness of 600 μm, and on top of that, a curing agent (Catalyst PL-4 Shin-Etsu Chemical Co., Ltd.) was added at 1% of the resin. A toluene solution of the added silicone resin (KS772 Shin-Etsu Chemical Co., Ltd.) was applied and dried (150° C., 5 minutes) to form a silicone resin layer with a thickness of about 0.5 μm. Next, apply ink (Dry Ocolor Process Ink S) to the other side of the film.
Dainippon Ink & Chemicals Co., Ltd.) was thoroughly kneaded and applied using a roller.

像ができた。An experimental machine as shown in Figure 2 was created, and this printing medium was used for printing. When no electric signal was applied, ink did not stick to the ink-repellent layer and nothing could be written on the printing material (Gi), but when an electric signal was applied (voltage '8: 50V, pulse width 20μs). When applied, 82N102 in Figure 1
The anti-tR layer of the ink was destroyed and holes were formed, ink was deposited on the holes and a clear image corresponding to the electrical signal was formed on the printing material.
