PURPOSE:To facilitate engraving of a hard material by applying a jig plate made of a photosensitive resin to the surface of the hard material with an easily soluble inorg. material double adhesive tape, facilitating manufacture of the plate, and preventing fire damage due to its blast working. CONSTITUTION:An easily soluble inorg. double adhesive tape 2 is applied to the surface of a photosensitive resin plate 3, and the other side of the tape 2 is applied to the surface of a hard material 1, and an original plate 4 is placed on the other surface of the plate 3, and the original plate 4 is irradiated with UV rays V. The parts 31 of the plate 3 just under the transparent parts 41 of the original plate 4 are hardened but the parts 32 just under the opaque parts 42 are not hardened, so the plate 4 is removed, and the surface of the plate 3 is brushed with water, resulting directly forming a patterned resin jig plate 6 on the material 1. The pattern is engraved by blasting sand immediately after drying. At that time, the plate 6 is hardened, and not damaged due to firing. After the end of engraving, the plate 6 is taken off and the adhesive tape 2 is removed with washing with water or the like, thus easily accomplishing engraving the hard material. |
