Apparatus for photographically producing characters or other representations

Apparatus for use in the photographic production of characters or the like, according to a method of photographically producing characters or other representations under daylight conditions, in particular title set, on photo material, comprising, in combination:

• (a) a sheet of photo material (10) of the type which is insensitive with respect to daylight and sufficiently sensitive with respect to short-wave light;
• (b) a wetting developer liquid absorbed on at least one side of said photo material;
• (c) a transparent cover film (12) disposed adjacent said one side of said photo material to protect the same from evaporation of said developer liquid;
• (d) a recording carrier film (15) having transparent regions (16) on a coloured ground which is opaque with respect to short-wave light disposed adjacent said cover film on the side thereof remote from said photo material in a suitable position relative to said photo material, with a selected one of said transparent regions, which are in the form of characters or the like, aligned with a selected area of said photo material;
• and
• (e) a flash device (20) having a transparent flat pressure plate (23) in front of its light aperture and including means (25) operable to produce short-wave light flashes for irradiating the selected transparent region of the recording carrier film, said flash device being manually positionable adjacent said carrier film with said plate disposed thereagainst for exposure of said photo material with short-wave light transmitted through a selected one of said transparent regions of said carrier film to form a corresponding image on the photo material which becomes rapidly visible to the naked eye immediately following said exposure by said flash device.

Apparatus in kit form adapted to be assembled and used for performing a method of photographically producing characters and other representations under daylight conditions, such as title set, said apparatus including in combination, photo material in sheet form which is generally insensitive with respect to daylight including blue light and having a predetermined sensitivity with respect to short-wave light, a suitable developer liquid for pre-wetting said photo material, a light box, said light box having a light source for producing visible light which is non-actinic relative to said photo material and a support plate supporting said photo material and transmissive for at least some of said visible light to illuminate said photo material, a transparent cover film which is non-transmissive with respect to said developer liquid and positionable over said developer pre-wetted photo material, a record carrier film positionable over said cover film, said record carrier film having a background which is opaque to said short-wave light and light transmissive for at least some of said non-actinic light, and transparent regions in the form of said characters or other representations to be produced, and a flash device adapted to be manually positioned above said character or other representations to be produced, said flash device having a light source for producing said short-wave light and an aperture to be directed on said character or other representation to be produced from said record carrier, said apparatus being especially adapted for manually performing the following method:

• (a) placing said photo material onto said light box and illuminating the same with said light source,
• (b) wetting said photo material with said developing liquid,
• (c) covering said wetted photo material with said transparent cover film,
• (d) relatively positioning said record carrier film and said transparent cover film such that said one transparent region is juxtaposed to where its projected image is to be produced on said photo material,
• (e) irradiating said one transparent region with shortwave light so as to activate the photo material in the area juxtaposed to said one transparent region to thereby provide a corresponding image on the photo material which becomes immediately visible to the naked eye in daylight conditions.

Apparatus in kit form for photographically producing characters or other representations under daylight conditions, such as title set, comprising photo material in sheet form which is generally insensitive with respect to daylight including blue light and having a predetermined sensitivity with respect to short-wave light, a source of short-wave light, a developer liquid suitable for said photo material, a transparent cover film which is non-transmissive with respect to said developer liquid and a record carrier film which has at least one transparent region in the form of a character, symbol, picture, photo or other like representation surrounded by a ground which is opaque with respect to short-wave light to thereby provide a photostenciling implement, said photo material being adapted to be wetted with said developing liquid and then covered with said transparent cover film, said record carrier film being relatively positionable on said cover film on the side thereof opposite to said photo material and such that said one transparent region is juxtaposed to where its projected image is to be produced on said photo material, said short-wave light source being manually positionable for irradiating said one transparent region with short-wave light so as to activate the photo material in the area juxtaposed to said one transparent region to thereby produce a corresponding image on the photo material which becomes immediately visible to the naked eye in daylight conditions.
