INK PRODUCT AND rnoonss or MAKING THE SAME" No Drawing.

The present invention relates to an. ink product and process of making the same, the invention being more particularly related to an improved printing ink product and. its process of manufacture.

Hitherto, in the art of lithographing, label printing and in similar lines of work, it has been the practice to print gold size on the sheets, allow the printing to dry to a certain extent and become tackey, and then to print thereon gold or other colored bronzes. Under this practice it has been customary to carry out two distinct printing operations;

first, the printing of the gold size, and then the printing of the gold bronze. In addition to these two distinct operations, there, is another attendant disadvantage in that the gold bronze which is printed in dry poW- dered form escapes into the surrounding atmosphere and thence settles upon the print-- ing machines, paper stock and persons. within the printing room, the powdered gold bronze frequently having an injurious efiect upon the persons inhaling the same.

The object and purpose of my invention are to provide a ready mixed gold or other colored bronze, having the character of an ink, either in liquid, semi-liquid or paste form, capable of being applied in one printing operation.

Another object is-to provide an improved product, as stated, whereby lithographers, label printers and others engaged in printing sheets in gold bronzes may perform their work quickly, economically, and without the use of the powdered product.

Other objects will appear hereinafter.

My improved product consists of a mixture of cresylic acid, sulphuric acid, borax, flour, chrome yellow and gold bronze, together with a vehicle which holds the other elements in a suitable ready mixed state until they have been printed upon the sheet.

The best formula embodying my invention at present known to me, and the preferred process of making, compounding and using the same, according to my present information, is as follows:

I make a product aggregate consisting, by weight, of about thirty percentum of the Application filed Augustfi, 1929. Serial No. 384,487.

base ingredients, commercially referred to as pigments, and seventy percentum of :VGlllClB materials, although these proportions may be varied greatly in accordance with the general character of the product to. be obtained,

whether in theform of athin liquid paste 2 ink, a semi-paste ink or a full paste ink. For the base or plgment aggregate, entering intothe product, I prefer to use ingredients in about the following proportions, byv weight, cresylic acid eight percentum,1s'ulphuric acid four percentum, borax fifteen-z it percentum, ,fiour sixty percentum, chrome yellow three percentum and gold bronzeten.

percentum. For the vehicle aggregate, en-

tering into the product, I prefer to take about ninety percentum of water and ten per-.

centum of varnish. Good results may be ob-- tained, however, when the materials, both of the pigments and vehicles, are varied within the limits of. twenty percentum of the proportions given.

All of the .materials fmay be introduced and mixed at the same time, and they are cooked at about boiling temperature until thoroughlyfand uniformly mixed as a ready I 'mixed product in the state desired, that is to say, a thin. liquid paste ink, a semi-paste ink or a full paste ink.

The improved ink. product produced asabove described is very economical in manufacture, and is highlyeflicient as a ready.

mixed gold ink or bronze ink.

- The method of application may vary in accordance with the character of the printing press, device or apparatus used in printing. It is, of course, well known that lithographers use either an offset printing machine or a flat-bed litho press. When employing the offset machine the lithographers print from an aluminum or zinc plate. Where a flat-bed press is used the printing is done from a stone. Label printers print from an electroplate. M ready mixed ink product can be used to a vantage in all of these methods of printing. f In pressprinting the. especially prepared plate is very sensitiveto grease. When the press is set in motion a set of flannet rollers (kept moist by contact with water) pass'over the surface of the plate, slight- 1y Wetting it. Immediately following the damp rollers are, the ink rollers, which distribute the ready mixed ink product smoothly and evenly over the designs on the surface of the plate. In this process, the thin coating of Water prevents the ink product from adhering to the plate and only the designs thereof receive an application of the ink product.

It may be remarked here that Whenever the ready mixed gold or bronze ink product is too heavy, the same may be reduced to a suitable consistency by the addition of a suitable grease compound, for instance, petroleum jelly .or

consistency of the product may be varied according to the character of the Work and ac- Z cording to the judgment of the manin'charge of the press. i p While I have given above the best formula embodying my invention at present-known 'to' me; and the preferred compounding and using the same, I-reahze that in practice other combinations of pig ments might be used besides those before mentioned, and the process of compounding may bevaried as experiencedictates, to produce the precise ch'aracter and colorof ready mixed be desired for printing purposes. It is to be understood, therefore,

making the product may be made therein, to which changes and modifications I am entitled, provided the same are effected within the scope of the annexed claims.
