Description

PATENT OFFICE.
ARTHUR GORQUATTO JOSEPH MARCHISIO, O-F PARIS, FRANCE.
IMITATION-COPPER-ENGRAVING PROCESS.
No Drawing.
To all whom it may concern:
Be it known that I, ARTHUR CoR UATTo JOSEPH Manorrrsro, a subject of the Kingof Italy, residing at Paris, France, have 1nvented new and useful Improvements in Imitation-Copper-Engraving Processes, of which the following is a specification.
This invention is an imitation copper engraving process, the object of the invention being to provide an improved process by means of which photographic prints ca n be readily produced which perfectly nnltate copper plate engraving, etching and the like, and which process may be employed in the execution of work of various kinds, such as postage-stamps, vignettes, tail pieces, illustrations, postal cards, and all kinds of drawings, and requires no previous training on the part of the operator, further than the ability to make a drawing.
In carrying out my improved process, a drawing or the like is made with a metallic point such, for instance as a needle, or graver, upon a glass or transparent celluloid plate upon which has been first spread a layer of a more or less inactinic coating and then a layer of white coating.
The first layer has for its object to partially or entirely stop the luminous rays while the second layer during the execution of the process permits the lines of the drawing to appear in black.
When the drawing is finished the plate is used as a photographic negative and positives are made therefrom on bromid paper or on any other photographic paper according to effects to be obtained.
The execution of the drawing in accordance with my process is much quicker than on paper and the positives are obtained in a few minutes while the copper-engraving processes heretofore commonly employed required at least two days of manipulations before a positive of the plate should be impressed.
Specification of Letters Patent.
Patented July 26, 1921.
Application filed September 22, 1919. Serial No. 325,423.
My improved process obviates danger and is very clean and it does not necessitate a special plant with a screen to obtain a diffused light, and moreover an apprenticeship is not necessary since any person who can draw will be able to readily carry out my process.-
If after the printing of the first positive it is seen that certain parts of the drawing need to be reinforced, it will be possible to execute such reinforcement without having to submit the plate to any preparation.
To enable positives to be obtained either with tinted grounds or with white grounds, the plates will be prepared previously in two ways.
There will be first plates A giving to the drawing a slight tint, as the first layer interceptsthe light only partially. This allows whites to be taken off on lighted parts of the drawing by means of a black and soft pencil.
They are afterward plates B completely inactinic and giving therefore very neat lineswithout any half-tint as in copper-em graving.
These plates will be made in series and they may be sold in pockets with any number of them and with a black board to be used to display black lines, a blue pencil and a dry point to make the drawing.
What I claim is:
An imitation copper engraving process consisting in providing a transparent plate with a partially inactinic coating and a white supercoating; delineating the desired sketch or drawing on the supercoating, cutting through both of said coatings on the lines of the drawing with a dry point to expose the clean surface of the plate, tinting parts of the drawing by appropriately using a soft black pencil on the said supercoating, and subjecting prepared paper for the usual print process to the action of the light through the plate.
