ABSTRACT Improvements in or relating to the exposure of radiation sensitive materials An apparatus for copying transparent and optionally mask films (19,20) onto a radiation sensitive plate (12) comprises a plate carrier (2) on which one or more radiation sensitive plates (12) and one or more transparent films (20) and optionally mask films (19) can be placed in predetermined mutual positions. The apparatus includes a contact frame (3) having means (18) for vacuum connecting the contact frame (3) to the plate carrier (2) and means (V1,V2) for vacuum connecting the transparent film(s) (20) and the mask film(s) (19) to a contact glass (16) of the contact frame (3). An exposure light (4) is provided for directing radiation through the transparent film(s) (20) and the mask film(s) (19) so as to copy them onto the radiation sensitive plate (12). The plate carrier (2) comprises a flexible support plate (8) which is connected to the apparatus frame (1) only along its outer edges, and which carries a flexible rubber blanket (10), which is connected to the support plate (8) only along its outer edges. The support plate (8) together with the rubber blanket (10) and the radiation sensitive plate (12) are able to bend convexly upwards under the influence of the vacuum and into contact with the contact frame (3) starting at the centre of the contact frame (3) and thereafter successively proceeding out in all directions towards the edges of the contact frame (3) until there is a total contact.
