Abstract

487,570. Photo-mechanical printing- surfaces. ODHAMS (WATFORD), Ltd., and VERRIOUR, S. J. Aug. 18, 1937, No. 28212. Divided application. [Class 98 (ii)] Photogravure and rotagravure printing formes including both matter reducible to type or line matter and pictorial matter, are prepared by making a negative of the pictorial matter in white on a black ground, making a negative of the type matter in a light colour on a black ground, planning the negatives on a black background and making a diapositive of the planned negatives from which the forme is prepared in known manner. The negatives are preferably made on paper, that for the type matter being dyed, tinted, or fogged to give a light colour. The type matter may be prepared by taking a pull from an original printing plate in black ink on a white paper and producing a negative with lightly coloured characters therefrom. Specification 308,592, [Class 98 (ii)], is referred to.
