IPC: G03F1/90
Filed: 1916-11-02
Abstract: 115,444. Agger, E. E. Nov. 2, 1916. Drawings to Specification. Printing processes and apparatus. - Printing- plates are produced by imprinting upon a sheet of suitable material, for example thin strong paper, a line or lines of characters in page or column alinernent, rendering the sheet adhesive and causing it to adhere to a translucent support, for example a sheet of glass or celluloid, by an adhesive which permits the sheet to be repeatedly applied to and removed from the support, and reproducing the line or lines of characters upon the sensitized surface of the printing-plate by the action of light transmitted through the sheet and support. When the sheet is not translucent or is only partially translucent, an adhesive is used which renders the sheet light transmitting. A suitable adhesive, which is also moisture resisting and does not evaporate appreciably, consists of beeswax, or paraffin, or other wax dissolved in benzole until it is of a thick creamy consistency. The characters may be printed in any suitable ink which may be sized to hold opaquing material, for example bronze powder or the like. Corrections are made by severing the incorrect portion from the rest of the sheet while adhering to the support, removing the severed portion and adhering a corrected portion to the sheet in place thereof.
