ABSTRACT:
The invention relates to scanning apparatus including a transparency support (12) and scanning means (3,4,5) for scanning a transparency (1) on the support to generate an electronic representation of an image defined by the transparency (1). The surface (24) of the support (12) which carries a transparency (1) in use has a surface profile with irregular undulations (25) such that any Newton's rings formed between the transparency (1) and the surface (24) of the support (12) cannot be resolved by the scanning means in use. Methods of producing the irregular undulations are also described.
