Abstract
457,546. Photographic plates provided with line screens. THERIAT, J., 41, Rue Billaut, La Courneuve, Seine, France. Feb. 23, 1935, No. 5887. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 26, 1935]. Drawings to Specification. [Class 98 (ii)] A photographic plate or film consists of a base of glass or celluloid, a line screen on one of the faces of the support and an emulsion applied after the line screen. The screen may be interposed between the emulsion and the support and may be of black and white or of coloured lines. It may be prepared by printing, electro-deposition, or by mechanical means. In an example, a block constructed as described in Specification 456,968, [Group XVI], consisting of groups of two projecting and one recessed element with two projecting elements at one end is used as follows. A set of lines in one colour is printed with the block, one end element is removed and a fresh set of lines printed in a different ink, the previously formed lines being covered by one set of projecting elements. The second end element is removed and printing effected in a third colour. The resulting screen may be reproduced if desired.
