| titleOfInvention | Improvements in and relating to the Manufacture of Photoprinting Blocks. |
| abstract | 27,158. Lake, H. H., [Klimsch & Co.]. Dec. 29. Etching.-The grain for a photo-printing block is produced by volatilizing a solution of resins, balsams, oils, or the like upon an exposed plate sensitized with chrome-alum &c. The resin precipitates into single points and dots corresponding in size and disposition to the tints and designs of the picture. Immediately after the grain is produced, the plate may be etched by dilute nitric acid or otherwise, and gummed and treated in the usual manner. Or, instead, the chromatic salts may first of all be washed out of the coating. The grain is varied by adding to the solution other ingredients such as resins, calcium chloride, turpentine, or other alkalies. Even flooding of the plate is effected by means of a whirler. The evaporation should take place under constant conditions of heat and moisture of the plate, the solution, and the workroom. As dampness to saturation point is not advisabie, the plate and its support are previously heated to exceed slightly the temperature of the room, the resin solution being alone heated to the same temperature. |
