Abstract: A light box is for supporting a stack of essentially transparent sheets including photo material which is insensitive to daylight and sensitive to shortwave light, and a record carrier film having transparent regions in the form of the characters or other representations to be produced and an opaque background to shortwave light. The illumination by the light box facilitates positioning of the record carrier film relatively to the photo material, and a grid can be a further help in positioning. A flash device having an aperture, the size of which corresponds to the size of the character or other representation, is for producing the shortwave light to blacken the photo material corresponding to the selected record on the record carrier film.

Abstract: Photographic production of characters (11) and the like for the title set on photo material (10) which is insensitive in respect of daylight and sufficiently sensitive in respect of short-wave light. Developer liquid wettens the photo material (10) and is protected by a millimeter grid cover film (12). A recording carrier film (15) with transparent letters (16) and the like, on a colored ground which is opaque in respect of short-wave light, is laid on the photo material or cover film and moved into a condition of alignment (millimeter grid). Short-wave light of the correct amount is produced by a special flash device (20).
