To all whom it may concern Be it known that 1, WILLIAM BERRY, a subject of His Majesty the King of England, residing at 17 Ivydale road, Nunhead, in the count-y of Kent, Kingdom of England, have invented a certain new and useful Improved Method of Printing, of which the following is a specification.

This invention relates to a new or improved method of printing for the purpose of enabling more realistic textile or other like effects to be obtained.

The invention is applicable for a variety of purposes for instance as picture postcards, advertising leaflets or posters, fashion books or cards for illustrating wearing apparel and other subjects l-leretofore in the manufacture of flock paper hangings it has been proposed to employ engraved wooden blocks for the purpose of applying the mordant or flocking size to the surface of the paper, and fur ther it has also been proposed in a printing process for imitating woven fabric, pastel painting, lace, gobelins and the like, in which plain or colored flock is applied to a design printed in ink or a colorless adhesive by means of a stone, plate or cylinder, to coat the finished layer of flock with varnish or lacquer before subsequent color printings thereon. These operations of printing and varnishing or lacquering it is proposed to repeat several times before the color printing in order to obtain surface unevenness in the attern, and it is also stated in such proposition that instead of a powdered background a colored covering layer may be used.

In carrying out my invent-ion I apply in the known manner to a part, or the whole surface of the paper or a black and white or colored representation or picture a suitable adhesive substance, upon which I subsequently deposit black, white, or colored flock or other fibrous materials. And according to my invention 1 then print over the surface of the flock, by means of line, tone, or other suitably prepared blocks, in order to obtain the desired effect of light and shade or' coloring; this printing taking place without further treatment of the flock. For instance in applying the invent-ion to tailors or clothiers fashion cards the flock or the like would resemble the actual pattern and coloring of the cloth to be advertised and more than one deposit or representation could be applied to the different parts of a Specification of Letters Patent.

single figure or plate the deposits being placed thereon in any convenient manner by hand or by machine printing and in a dry or moist form. If the surface or partthereof to be covered is of one color the deposits may be first colored as desired before application or it may be put on white and in either case such surface may be afterward printed upon with suitable dye colors. The skins of animals, fabrics, or floor and wall coverings may also conveniently be represented in this manner and natural effects can be thereby obtained.

A block is employed to print upon the representation in the desired parts the adhesive material to be applied. After this has been done the representation is then coated in the prepared places with the flock. This is done by placing the representation in a box or casing in which the flock is dusted on or otherwise applied by means of a blast or by passing it between rollers provided for the purpose. The adhesive material may itself be white or suitably colored to enrich the finished effect or in some cases form a complementary color in conjunction with a colored flock.

If the cloth or fabric to be represented is red and contains say black lines interwoven therein, then these are produced by subsequent printings in dyes or inks from blocks suitably prepared for printing on the flock surface. In like manner two or more colors or complementary colorings may be applied to give any desired effect as will be hereinafter described.

I will now describe the preferred manner of preparing the key and other blocks especially suitable for more complicated applications where key blocks and a number of blocks for the various color and other printings are required. I first of all take a photograph of the original article to be represented or of the original drawing orrepresentation as the case may be, and in the present instance I suppose this to bea soldier or the like. The negative so produced may be a line or tone reproduction as is found to be most suitable to the particular case. 1 next prepare a bright zinc plate with a suitable chemical such as chlorid of antimony, to give it a blackened appearance and this plate after being dried is sensitized by the application of a suitable bichromate solution. This plate is then placed in a frame with the negative and printed.

It is then inked up with a mixture of lithographic transfer ink and spirits of turpentine and subsequently developed in water so as to leave only the inked up image on a dark metal plate. plate is now lightly developed in weak acid which leaves the metal bright between the image. The ink deposit is then washed off with spirits of turpentine and the resulting plate is now an image or ofiset from the photograph. A number of these plates are thus provided for the preparation of blocks for printing in the various colors, one plate for each color. After this they are etched deep to give the work in relief. Thus I may provide say one keyblock bearing the whole outline or representation; one, two or more other blocks for the flat color printing, one or more for the gumming process and one or more for subsequently printing on the surface of the flock deposit to represent the shadows or pattern on the clothes.

All the fiat printing is done first whether in colors or in black and white and after this is completed those parts that are to receive the flock are then prepared and the flock applied either in one operation or in several operations according to the requirements. For instance the red coat of a soldier could be applied in one operation and printed upon to give light and shade effects and the other differently colored garments in subsequent operations, or they may be all put together at one operation in plain or a mono-color and subsequently dyed or the texture printed thereon by other printings. The adhesive substance may conveniently comprise a stiff varnish mixed up with a flake white or another medium and if desired suitably colored, but such substance is only given as a suitable example as it would be varied to suit the nature of the paper or the like to be printed upon and the compositions of the inks and dyes.

If a. carpet is to be reproduced line blocks would preferably be employed and the flock would be first laid on and the various colors subsequently applied in proper order, and in such cases if the article is properly photographed the fabric of the carpet will be accurately reproduced upon the surface of This zinc the flock by the printing bloc s themselves as the texture of the article itself will act as a line screen in most cases. A very artistic effect may be produced in some cases by graining or blasting the surface of the various blocks employed so as to give a tone to the finished reproduction.

What I claim as my invention and desire to secure by Letters Patent of the United States is':

1. The process of producing textile or like effects in printing, which consists in first flat-printing the design directly upon a surface, then applying adhesive thereon in circumscribed areas less than that of the printed design, then applying flock to the adhesive, and then printing directly upon the flock, said floc and the initially printed design remaining otherwise fully exposed in the finished production.

2. The process of producing textile and other like effects in conjunction with printing and of less area than the printed image,

which consists in flat-printing upon a pape or like surface a representation of the desired complete image, then applying an adhesive to circumscribed parts of the complete image representing those parts of the surface to subsequently appear in textile effect, then applying flock to the adhesive, and finally completing the textile or like effect by imprinting directly upon and in cluding so much of the flock surface as to combine with the unprinted flock surface to produce the desired effect, said flock surface remaining otherwise fully exposed.

3. The process of producing textile or like effects in printing, which consists in first applying an adhesive to the surface to be treated, then applying flock thereto, and finally printing directly upon a portion only of the flock surface so produced to such an extent as to combine with the unprinted portion of the flock surface to produce the desired effect, said flock surface remaining otherwise fully exposed.

In testimony whereof I afiix my signature in presence of two witnesses.
