ELLIS BASSIST, OF NEW YORK, N. Y., ASSIGNOB TO EDWARD G. SOLTMANN, OF
NEW YORK, N. Y.
Specification of Letters Patent.
Patented May 10, 1919.
Application filed May 4, 1809. Serial No. 493,817.
To all whom it may concern:
Be it known that I, ELLIS BAssIs'r, a former subject of the King of Hungary, and who have declared my intention of becoming a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Processes for Producing Printing-Plates, of which the following is a specification.
My invention relates to a process for preparing, by photographic'means, a metallic or stone surface for lithographic or typographic printing; and it has for its object to reproduce in quantity and in a simple and inexpensive manner, upon the same, an enlarged, or a reduced scale, pictures, engravings, drawings, sketches, and the like.
In the accompanying drawings which illustrate my inventionFigure 1 represents a small sheet upon which the letter S has been printed or otherwise applied. Fig. 2 represents a negative made from the same, and reduced to the size shown. Fig. 3 represents a positive made from said negative, and enlarged to twice the size of the original Fig. 4 represents the plate for printing the copies after the said positive has been exposed thereon and the said plate washed. Fig. 5 is a similar view after etching and preparing the plate for printing. Fig. 6 represents a print made therefrom.
In carrying out the process I first make from the original (Fig. 1) a negative (Fig. 2) in the usual manner and of any convenient size, the negative shown being reduced. From this negative a positive (Fig. 3) is made, corresponding to the final size of the reproduction desired. This is preferablymade upon paper such as the well-known solar print paper, or bromid paper, although any suitable material properly sensitized and which is or may be made transparent, may be employed. This positive if not sufiiciently transparent may readily be made so by applying oil such as kerosene, gasolene, or fatty oils to the same. The positive, sufficiently transparent, is then placed face down upon a suitable sensitized printing plate (Figs. 4 and 5) such as an alummum, copper or zinc plate, or upon a stone, and exposed for the proper length of time. This plate has been previously coated with a sensitized glue mixture, and the action of the light is to so alter the portions exposed to the action of the light rays that these are not removed by a subsequent washing with water. The plate after the exposure, is flowed over with Water which removes the unexposed portions, the plate appearing as in Fig. 4. If it be desired to prove the exposure, the plate may be flowed over with an anilin ink solution which is afterward removed by a weak solution of hydrochloric acid. After this, the plate is dried and inked with a fatty ink, the ink settling in the Washed out portions of the plate and.
adhering to said plate itself at such ortions, while the portions afi'ected by the l ght prevent the ink from reaching the plate and are covered with a film of ink. The plate is then placed in water and rubbed while in the water, whereby the said portions acted upon by the light are removed together with their adhering film of ink, leaving the late marked only where the ink has reache the same and reproducing the original, but reversed (Fig. 5). The. plate is then etched and prepared in the usual manner in lithographic processes, and the copies (Fig. 6) printed therefrom. In this manner any desired number of copies as well as of any desired size may be readily and inexpensively obtained. The process is especially valuable for making reproductions of considerable size, as the negative is not required to be large; and the positive, which is necessarily of the size of the reproduction, can be made upon sensitized paper which may be readily obtained in large sizes, impossible or prohibitive if of glass.
I claim 1. The method of producing printed matter in any size from an original, consisting in photographically producing a photographic ne ative on a suitable material from the originzfi, then photographicallyproducing from the said photographic negative an enlarged photographic print; then superimposing the said hotographic print on the sensitized face 0 a printing plate and subjecting the same to the action of light, then completing the plate to form a printin surface of the subject matter of the repr uced original; and finally printing from this late.
2. The method of producing printed matter in any size from an original, consisting in photographically producing a hotographic negative on a suitable materia from the ori inal, then photographically producing rom the said photographic negative an enlarged photographic print;.then su erimposing the said photographic print ace down on the face of a printing plate and subjecting the same to the action of light; then Washing remove the portions not exposed to the light; inking said entire plate; removing the portions of the plate exposed to the action of the light together With the attached film of ink by rubbing under water; etching and preparing the plate in the usual manner; and finally printing from this plate.
3. The method of producing printed matter in-large form from a miniature original, consisting in photographically producing a miniature photographic negative on a suitable material from the miniature original, then photographically producing from the said miniature photographic negative an enlarged photographic print, then superimposing the said enlarged photographic print on the sensitized face of a printing plate and subjecting the same to the action of light, then successively fixing and etching the the said plate with water to printing plate to form a printing surface of" the subject matter of the said enlarged photographic print, and finally printing from this printing plate.
4. The method of producing printed matter in large form from an original, consisting in photographically producing a photographic negative on a suitable material from the original, then photographically produclng trom the said photographic negative an enlarged photo raphic print, then superimposing the sai enlarged photographic print on the sensitized face of a printing plate and subjecting the same to the action of light, then successively fixing and etching the printing plate to form a printing surface of the subject matter of the said en-' larged photographic print, and finally printing from this late.
Signed at ew York in the county of New York and State of New York this 3rd day of May A. D. 1909.
