    • A flexible character-indentable plastics embossing tape (11) is backed by and bonded to a lead strip not more than 0.025 inches (ie. approximately 0.65 millimetres) thick, to form a tape suitable for identifying radiographs. The lead strip (13) is itself backed by a relatively thin and flimsy plastics or fabric strip (15) which, when removed, allows the lead (and hence the lead-plastic tape as a whole) to be pressure-bonded to the surface to be radiographed.
      A conventional tape-embossing gun is used to indent the desired characters in succession, and in order, into the lead-backed tape, without necessarily severing the lead; and then the backing strip (15) is peeled away to expose the layer (14) of adhesive which pressure-bonds the indented tape to the object to be radiographed.
      X-rays incident on the embossed tape will cause the raised characters (a) to show up dark on the subsequently-developed film, whilst the raised side areas (b) will show up white. Each character will thus stand out on the developed film.
    • 柔性字符 - 不可压缩的塑料压花带(11)由不超过0.025英寸(即大约0.65毫米)厚的导线条支撑并结合到一起,以形成适合于识别放射照片的带。 引线条(13)本身由相对薄且脆弱的塑料或织物带(15)支撑,当被去除时,其允许引线(并且因此铅塑料带作为整体)被压接到表面 被拍摄。 使用传统的带状压花枪来连续缩小所需的字符,并且按顺序进入带背胶带,而不必切断引线; 然后将背衬条(15)剥离以露出粘合剂层(14),粘合剂层将压痕带压接到待射出的物体上。 入射在压花带上的X射线将导致凸起的字符(a)在随后显影的胶片上显得黑暗,而凸起的侧面区域(b)将显示为白色。 因此,每个角色将在开发的电影上脱颖而出。
