l IIHA UNITED STATES PATENT I HENRY A. WISE WOOD, OF NEW YORK, N. Y., ASSIGNbR, BY MESNE ASSIGNMENTS, TO WOOD & NATHAN COMPANY, OF NEW YORK, N. Y., A CORPORATIDJE-M INTAGLIO AND RELIEF PRINTING DEVICE.

To all whom it may concern: 7

Device, of which the following is a specification. I

This case is in part a continuation of my application for patent on lntaglio printing plate Serial No. 317,456, filed May 18, 190 6. My invention relates to improvements in intaglio printing, the particular Ob ects thereof being to provide means whereby intaglio printing plates can be employed in the place of orin connection wlth the relief printing plates or surfaces now n common use-and to avoid certain compllcations which heretofore have been thought to be of such nature as to render such use of intagho pl ates impracticable.

In the use of intaglio p1ates, the papercontacting portion which contains the de sign and the non-printing portlons hereto fore have been one and the same, surface, all lane. The design is filled with inkand all surplus ink is removed from the plate-by some wiping or scraping means; Obviously, it is' of the utmost im ortance that the non-printing surface of t e plate be free from lnk before the printing operati on is performed. This ren- L dersit necessary to keep the non-printing portion. of the plate entirely free from scratches and other indentations which would fill with ink'and print marks in the surface whichsho'uld be clear. The use of a very high quality of copperin the preparation of'these plates therefore is necessary. 40

and extreme care in their manipulation absolutely essential. In order to avoid these difii'culties, I- have produced a plate provided with a non-pressing and non-printing .surface depressed below the paper-contacting'surface, and provided with means whereby the scraping or wiping device may be gradually guided upon the paper-contacting surface "in such a manner as effectively to clean the latter. v

Reference-is to be had to the accompany Ting sheet of drawings which illustrate mech anlsin A for. carrying out this invention and in which, Figure 1 is a plan of a flat printing having relief and intaglio surfaces thereon Specification of Letters Patent.

Fig. 2 is a sectional view of the same on the 1 i which is provided with lines or engraving 1:

representing the intaglio design. It is of such formas to be capable of generation by the motion of a right line.- It is surrounded or bounded on one or more sides by a non-pressing surface in a lowerplane; Upon' the same-plate is also shown a design or composition in relief in the form of raised letters 7). It will be seen that the upper surfaces of the letters 71 are in a lower plane than the surface of the design a. This set so that it will clean the surface a without lHtPIfQIJHfI with the ink on the surfaces b,

Fig. 3 is an end cleva-= tion of a printing cylinder having intao'lzio ,75 is to provide for the use of a cleaning blade both relief and intaglio parts of the plate being inked by the same inking roller. Inthe form shown in these two figures, the in-* taglio design preferably is surrounded by a ISO fineline a instead of being surrounded by a broad flat surface which has to be cleaned by the scraper. It will thus be seen that almost no surrounding paper impressing plane is left to be kept. clean. In other words, around the design and about its outer edge, I leave a paper-contactingsurface,

preferably of not over one-thirty second of an inch in width and all of the out-dyingplate is then brought. to the plane oftlie The part inside the non-pressing surface. l1ne a is that in which the intaglio design is produced and has all the characteristics of;

9.5 an intaglio plate. Moreover, the surface or 1 line a rises out of the non-printing surface 0 preferably through a'slanting' surface (1 gradually guides it to the surface which: has to be cleaned. It is not intended, however,

which engages the cleaning blade and that the cleaning blade should. comeinto contactwith the surface a in the form shown in these two figures. This surface d is provided for the purpose of guiding a scraping the forward edge of the latter shall be thoroughly cleaned and there shall be no sudden change of direction of the cleaning, means.

In certain kinds of printing in which effects can best be produced by intaglio' andrelief surfaces. the best results can be ob-. tained by.placing.'either on the same plate with an' intaglio design or on a separate plate, a relief surface for the ordinary'kinds of printing. l have shown this feature in the form of a surface of the ordinary relief type directly on the plate which bears the intaglio surface. The relief surface may be exactly the same height as the paper plane or -aper 'contacting portion of the intaglio sur' ace, but I prefer to make it of slightly less altitude, as-is indicated, so that there Will-he no danger of the cleaning blade taking the ink from the relief surface.

As I have stated above, the relief surface may or may not he on the same plate as the. intan'lio surface, the principles of the invention being complied with so long as they are printed from simultaneously. For a further disclosure of the invention, reference is to be had to Fig. 3 which shows several printing plates mounted upona printing cylinder. The intan'lio design is on a printing plate A while the ielief'design is on a printing: plate B. These plates in this inst anee are shown. as being formed separately and'individually mounted on the cyl- 'iiider.. It will. he noted, that the printing surfaces oft-lie plate B are in a lower plane,

" separate plates or at a shorter distance from the axis ofthe c \"liiu'ler, than those of the plate i This 'is f1 ii the same purpose, as that herciiibefore indicated. For the purpose of cleaning the surfaces of the intagrlio plate or plates,..a-

cleaning blade I) is shown. This blade be in; mounted in the usual way which is well, uiidcrsti-iod, will not he described in detail. 'l he blade is so located that. it will reach and 'ciug'agetlm sur-aces of the intaglio plate or plates and will not interi'rre with the ink on the relief.printing:surfaces. It will be seen from a eonsidc" tion of the drap'ings that the relief and ii actlio plates may either be type may beei nplo \'-'edv surrounding the .tanlio design outhe-ttvo kinds'of surfaces inn} he formed on the same plate.
