ART OF MANUFACTURING PRINTING SURFACES.

Application filed October 19, 1922. Serial No. 595,572.

To (/17 '10 from. it may concern:

Be it known that I, JULIAN FREEDMAN, a citizen of the United States of America, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in the Art of Manufacturing Printing Surfaces, of which the following is a specification.

My invention has reference to improvements in the manufacture of what are known in the art, as printing surfaces, and the primary object thereof resides in the provision of such surfaces that are comparatively inexpensive of manufacture and wherein the usual expensive metal or wood cuts may be dispensed with.

It is well known in the printing art, that when designs are to be printed these designs must necessarily be sketched by the artist or draftsman, and then transferred to the printing surface by engraving or other procedure. My invention contemplates the provision of a particular material wherein the design to be printed may be formed in outline directly thereon and then adequately cutting this material so that the design will stand out in relief. After the design has been formed in the material the same is suitably mounted upon a block memher or roller for insertion in the press for producing the prints.

In the drawing forming a part of the present application and wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a plan view of a strip of material forming my printing surface and disclosing the design to be printed sketched in outline thereon,

Figure 2 is a top plan view of the strip, a portion of the same being shown in section for fully disclosing the strip of material having a reinforcing fabric background, for purposes hereinafter more fully described,

Figure 3 is a plan view of the design to be printed, the same having been cut from the strip of material and also having been suitably worked by the artist whereby the different lines forming the design stand out in relief, the block or base to whichthe same is applied being shown in outline, and

Figure 4 is a transverse sectional view upon line IVIV of Fig. 3 and looking in the direction of the arrows.

Referring to the severalviews, in forming my printing surface I employ a strip of material 1 of any desired. configuration and of sufficient thickness to allow the same to be so cut as to provide the intermediate lines forming the design to be printed. The.

material forming the strip 1 is preferably of a composition or any material that is of a relatively soft and pliable nature. In manufacturing this material I provide the same with a reinforcing backing 2 of woven fabric, this backing effectually preventing any stretching or breaking of the material while the design is being cut or otherwise formed thereon.

As shown in Fig. 1, the design to be printed, designated by the numeral 3, is first sketched, in outline, upon the strip of material 1 at which time portions of the material may be cut away from the fabric backing 2 as to form the intermediate lines 3 of the design to be printed, as disclosed in Fig. 3. After the design has been fully completed upon the strip 1 the same is cut entirely therefrom for suitable mounting b y an adhesive or the like, upon the base block l, wherein the surface may be adequately mounted within a. press for the printing operation. From the foregoing description I believe it will be readily apparent to those skilled in the art that I have provided a printing surfacethat is a substantial improvement upon those now employed in the art of printing, and I wish it to be understood that minor changes may be made in the invention without departing from the spirit and scope thereof as claimed.

The material employed in the production of this printing surface provides for the ready cutting and working thereof, and is especially adapted for flat surface or poster printing, and isalso adaptable for multicolor and line work. The body thereof is of a soft and pliable nature but possesses sufficient tenacity to withstand the pressure in a printing press. With a printing surface of this character, extensive use thereof is contemplated where the usual expensive ,zinc cuts are prohibitive for certain classes of work in view of the costs. The finished prints possess qualities of the originalwork ing afibrous flexible backing, the "method" of sketching directly on that face of the strip opposite the fabriebacking, the design to be printed, cutting away portions of the material on the sketchd side of the strip With the sketch as a guide, to the fabric backing, and then cutting out the block.

In testimony whereof I affix nay signature.

it JULI N FREEDMAN.
