Method of producing a male mold for use in making a vacuum forming tool |
摘要 |
<p>A vacuum forming apparatus and process is provided for molding a thin sheet (88) of thermoformable plastic into an accurate three-dimensional relief reproduction of an original artwork. The sheet of plastic (88) has printed on one side thereof a permanent image of the original artwork. For producing a male mold (34;148) for use in making the female mold a moldable compound is applied to replicate brush strokes onto either a substrate (10) onto which an image is projected or a thermoformed plastic sheet (140) printed with an image. <IMAGE></p> |
