To'all whom it may concern:
Be it known that I, DAVID 'GESTETNER, a subject of the King of Great Britain and Ireland, and residirfig at Neo-Cyclostyle ale, London, N. 17,
' useful Improvements in and Relating to Duplicating, Manifolding, and the like, of which the following is a specification? This invention relates to methods of duplicating or manifolding, and has for its object to provide a method of duplicating or manifolding which shall produce copies resembling prints produced bythe employment of' an engraved plate, that is to say, prints in which the ink stands up on the 1mpression receiving surface.-
' According to the" invention a stencil, produced upon a Yoshino or like paper or on a suitable textile fabric, such as bolting cloth, by the employment of a photographic process of the kind in which the action of light is made use of for changing the solubility of a composition ,in regard to 'a solvent liquid used as a developer, is secured on a surface between which and the stencil an appreciably thick layer of a suitable ink is interposed, and prints or copies are produced by bringing the impression receiving surface into contact with the stencil surface. In forming the stencil, a process relying upon the capacity of elatin or gum tobe rendered insoluble as t e result of the action of light upon certain sensitizing b'odies may be employed.
Of processesof this kind, what are known as the gum bichromate and carbon processes may be specified.
In producing a stencil according to the carbon process, the print may be first made upon a light sensitive gelatin surface which may then be transferred to a temporary support and after development may be transferred from the temporary support to the Yoshino grlike paper or suitable fabric.
Alternatively, the sensitized colloid surface may. be applied in the first instance to the Yoshino or like paper or suitable fabric,
' which, after exposure under a suitable positive or negative to the action of light, is developed in order to effect the removal of the soluble colloid and produce a stencil; for instance, the Yoshino paper may, according to this method of operation,'be impregnated with a sensitized gelatin solution and the paper thus treated may be subjected to the specificati'on'of Letters Patent. Patented Oct 5, 192() Application filed February 26, 19-19. Serial No. 279,422.
body.
In accordance with the invention the ca-' pacity of asphaltum which, as is well known, can be rendered insoluble in benzin or similar coin ounds by the action of light, may be ma e use of for producing stencils resistant to the action of certain inks, for
instance, water inks containing relatively considerable proportions of gum" to giveto them a suitable consistency of brilliant appearance when dry.
According to this-phase of the invention,
the Yoshino or like paper or other suitable fabric may, if desired, be coated or impregnated with the asphaltum, or a print may 'be produced on a sheet of paper coated with asphaltum and the print then transferred to a sheet of Yoshino orlike paper or other suitable fabric.
The stencil produced in the above or in any other suitable manner if necessary or desirable after treatment with a softening agent such as glycerin is secured to a suita le supporting surface which has been provided with a coating of a suitable ink. The inks employed have, preferably, a composition similar to those of the inks at present used in processes ofreproduction involving the employment of engraved plates, thatis to say, they-fare varnish inks or'inks containing a suitable proportion of a water soluble gum 'or the like, and with advantage they have the character of the inksused 1n embossing in that they do not soak into'the impression receiving surface to any considerable extent.
It is further to be noted that the layer of ink on the support should be of appreciable thickness in order that the impression receiving surfaceshall take up a sufiicient i a I L c i I o impression rece'1v1ng surface w1th the aid, if
" necessary, of sufiicient pressure to produce the desired contact.
employed in accordance with the invention is only practicable when-stencils produced in the manner specified are used as stencils produced on porous supports by mechanical means as, for instance, by the employment of a typewriter or style, do not have sufli- I ciently fine' lines or such clearly defined boundaries to the thicker lines to produce prints or copies possessing a satisfactory ap earance. I
aving now described my invention, what I claim as new and desire to secure by Let-' ters Patent is:
l. method of duplicating or manifoldtextile fabric, such as boltingl cloth, by the employment of a photograp icprocess of the kind'in which the action oflight is made use of for changing the solubility of a composition in regard to a solvent liquid used as a developer, is secured on a surface between which and the stencil an appreciably thick layer of a suitable ink is inter osed, and prints or copies are produced by ringing the impression receiving surface into contact with the stencil surface.
2.'The process of duplicating, in which a stencil produced on a porous support by photographic means is secured to a suitable supporting surface which has been provided with an appreciably thick layer of an ink having a composition similar to those of the inks at present used in processes of reproduction involving the employment of engraved plates.
In testimony whereof I have signed my name to this specification. 'DAVID GESTETNER.
