POLYCHROME PRINTING PLATE Filed Feb. 12, 1942 m FIG. 2 M

Il/III Robert G. Chollar Inventor By zgawe/m His Attorney Patented Sept. 23, 1947 POLYCHROME PRINTING PLATE Robert G. Chollar, Dayton, Ohio, assignor to The National Cash Register Company, Dayton, Ohio, a corporation of Maryland Application February 12, 1942, Serial No. 430,662

4 Claims. 1

This invention relates to an improved means for obtaining polychrome prints during one printing operation from a single printing form.

An object of the invention is to provide a single printing form of micro-porous rubber having a plurality of sections thereon, each section being inked with an ink of a difierent color so that polychrome printing can be performed at a single printing operation from the single form.

It is a specific object of the invention to provide a printing form made of micro-porous rubber of a structure which is capable of absorbing and conducting printing ink to the printing face thereof, said form having a plurality of sections insulated from each other, and each section being saturated with a different color ink.

Another object of the invention is to provide a multi-section printing form, a separate ink font of colored ink for each section, and a separate wick to conduct colored ink from a font to an associated section of the printing form to provide a polychrome printing form.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawing which accompanies and forms a part of this specification,

In said drawing:

Fig. 1 is a schematic illustration of a single, multi-section printing form, indicating how the separate sections of the form are inked from individual fonts of ink through the medium of wicks.

Fig. 2 is a cross sectional view taken on line 2--2 of Fig. 1 and illustrates two modifications of the structure of the printing form.

General description The invention disclosed herein comprises a nov- 91 means-for polychrome printing, which printing can be performed by asingle operation. To accomplish this result, a printing form is constructed of a plurality of sections. drawings, three sections only are illustrated. However, any number of sections can be used. Each section of the printing form is inked with a difierent color ink, or, if desired, colors can be alternated.

In the specific form illustrated, the sections are made of porous rubber capable of absorbing and conducting the ink to the printing face of the form. Each section of the printing form is connected to a font of ink of any desired color, to

In the attached 2 constantly keep the form saturated with the required amount of ink. Capillary attraction maintains a constant flow of ink from the font to the associated section of the form.

Each section of micro-porous rubber is insulated from the other sections by solid partitions.

Detailed description The printing form is illustrated herein as being made in three sections I0 of micro-porous rubber, each section being insulated from the others and from the outside by partition walls H of solid rubber. One form of the invention discloses an insulating bottom l2 for each section. However, such bottom is optional as illustrated in the right-hand section of Fig. 2.

A wick l3 connects each section of the printing form with an ink supply well l4, each well containing a different color ink. Each wick l3 supplies its section with sufiicient ink by capillary action, and, each section of the form being constructed of micro-porous rubber, capillary action supplies the printing surface with the proper amount of ink to obtain legible impressions when the record material is pressed thereagainst as a platen in the usual manner.

As illustrated, the letters A, B, and C are shown on the face of the printing form, These letters are used as illustrations only. Any type, out, legends, or other data can be formed on the printing form so as to print any data desired.

As pointed out above, Fig. 1 does not illustrate the proportions of theparts relative to each other as they are actually used. In use, the printing form may be'smaller in size than the ink wells.

The printing plate is illustrated in the drawings herein as being made of micro-porous rubber, like that disclosed and claimed in my co-pending application Serial No. 427,326, which was filed on January 19, 1942, and which issued on July 18, 1944, as Patent No. 2,353,877.

Since each section of the printing form is at all times maintained saturated with a different color ink, a polychrome impression can be taken from the single printing form during a single operation of the printing mechanism.

While the form of the invention herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention 3 to the one form or embodiment disclosed, for it is susceptible of embodiment in various other forms all coming within the scope of th claims which follow.

What is claimed is:

1. A polychrome printing form constructed of a plurality of micro-porous rubber sections of a character which is capable of absorbing printers ink, and ink-impervious rubber partitions to inkinsulate the sections from each other, said sections and partitions united to form a stable unitary printing form.

2. A polychrome printing form constructed of a plurality of micro-porous rubber sections of a character which is capable of absorbing printer's ink; walls of ink-impervious rubber material to insulate the sections from each other, said sections and walls united to form a stable unitary printing form; and supply means to supply a separate color ink to each section.

3. A polychrome printing form constructed'of a plurality of micro-porous rubber sections of a character which is capable of absorbing printer's ink; ink-impervious rubber partitions to insulate the sections from each other, said sections and partitions united to form a stable unitary printing form; and means to supply ink or different colors to the surfaces of the micro-porous sections by capillary action.

4. A polychrome printing form constructed of a plurality of micro-porous rubber sections of a character which is capable of absorbing printer's ink, and ink-impervious rubber partitions to inkinsulate the sections from each other, said sections and partitions united into a stable unitary printing form and said printing form adapted for polychrome printing at a single operation of a printing platen.
