    • A process for the preparation of a printed draw-formed body having a printed image on the side wall thereof by subjecting a prior-printed blank to draw-forming, which comprises converting an image of an original to be printed to a digital image element signal on a rectangular coordinate, converting the image element signal on the rectangular coordinate to an image signal or image signals on a corresponding conversion coordinate formed by developing the rectangular coordinate to an annular plane having an area substantially equal to the area of said rectangle, reading image element signals on the conversion coordinate in order of the coordinate, photo-electrically converting the read image element signals to a printing plate for the blank and printing the blank by using the formed printing plate. According to this process, since digital coordinate conversion is performed while compensating anisotropy of the elongation of the metal blank, an improved printing precision can be obtained in a draw-formed body.
    • 一种用于通过对现有印刷的坯料进行拉伸成形来制备其侧壁上具有印刷图像的印刷拉制体的方法,其包括将要印刷的原稿的图像转换成数字图像元件信号 在矩形坐标上,将矩形坐标上的图像元素信号转换为通过将矩形坐标显影形成的相应转换坐标的图像信号或图像信号到具有基本上等于所述矩形的面积的面积的环形平面,读取图像 转换坐标上的元素信号,将读取的图像元素信号光电转换为用于坯料的印版,并通过使用所形成的印版印刷坯料。 根据该方法,由于在补偿金属坯料的伸长的各向异性的同时进行数字坐标转换,因此可以在拉制成形体中获得改善的印刷精度。
