160,922. Barrett, J., and Mell, A. N. Dec. 29, 1919. Drawings to Specification. Printing on celluloid; resist printing.-Signs, show cards, price tickets, tablets, lamp shades, &c. are made by printing, stencilling, or otherwise inscribing the design on sheet celluloid in what is known as printer's " overlay " ink, then immersing this sheet in methylated spirit containing dye-stuff so that the sheet, except the part carrying the design, is impregnated with colour, and subsequently removing the ink by means of paraffin or other hydrocarbon so that the design is left in the original colour of the sheet. The design may be tinted by the application of various colored spirit dyes, the superfluity of which may be removed by a hydrocarbon solvent, such as paraffin.
