ANDREW ROTH, OF NEW ORLEANS, LOUISIANA.
IMPROVEMENT IN PROCESSES 0F PRINTING PHOTOGRAPHIC PICTURES.
Specification forming part of Letters Patent No. 197,410, dated November 20, 1877 application filed September 4, 1877.
To all whom it may concern:
Be it known that I, ANDREW ROTH, a resident of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a certain new and useful Improvementin Printing Photographic Pictures; and I do hereby declare the following to be a full, clear, and
correct description of the same.
This invention relates to a process for printing photographic pictures, either direct from the plate or by first transferring them to a lithographic stone, so as to enable a lithographer, with the utmost accuracy, to reproduce v the same thereupon, thus admitting of the smooth photographic zinc plate, which is -af-. terward thoroughly dried and treated with a sensitizing solution, consisting of one ounce bichromate of potassa and fifteen ounces of cold water. The said plate is next slowly dried over a heated surface of metal, after which the picture is produced thereupon from a negative, in the usual manner. The bichromate of potassa is next all washed out, and ink is applied by means of a soft roller, and
the printing done in a lithographers press.
If the ink is stifi' I mix with about three parts thereof, say, one part of palm-oil, and then thin with turpentine or olive-oil, which is added drop by drop, until the proper consistency is obtained. If the ink is too thick it will only take in the deep parts; but if the proper consistency is obtained, it will take to the finest as well as the deepest shades.
A certain amount of care must be exercised in the printing from the negative, for if the plate is heavily printed it will take too much ink, while if, on the contrary, the print is but light, the soft shades will not be brought out at all.
The preparations above mentioned should be used fresh, and the plate, when not in use, should be kept in a dark room, particular care being taken not to let any acid reach its surface.
Having described my invention, what I claim as new, and desire to secure by Letters Patent,'is-- The process herein described of printing photographic pictures on paper, stone, or other material, the same consisting in coating the plate before sensitizing with a preparation composed of gelatine, tannin, rosin, alcohol, honey-soap, and water, about in the proportions named, substantially as and for the purpose described.
- In testimony whereof I have hereunto set my hand.
A. ROTH. In presence of A. MnRcAnAL, F. MI UET.
