-1 TECHNICAL PROCESS OF MULTI-COLOR DIRECT PRINTS IN A SINGLE PASS

BY CONJUGATED METHODS.

The present invention relates to a direct printing method making it possible, from the conventional method used in screen printing and an additional device, to reproduce either imitations of veined natural products, or to create multicolored abstract patterns and this in a single pass by a single, original and non-repetitive deposit of pigmented products of non-homogeneous shades, applicable on all supports, all materials (natural or synthetic), of all forms printable in serigraphy.

Attached are samples for models, these were made as being the most representative of the effects rendered. These samples are not limiting both on the support used and on the form, the nuances or the results obtained.

We know screen printing with its multiple applications.

Artistic or industrial methods are known which make it possible to achieve these same effects, but these methods do not make it possible to achieve them on finished raw materials, by a single deposit of multicolored colors effected in a single operation.

Indeed, artistic methods or the method by screen printing allow them to be produced at the discretion of the creator by successive contributions of colors juxtaposed or superimposed.

Industrial methods make it possible to achieve these effects in indirect, identical, repetitive ways.

The device according to the invention makes it possible to remedy these drawbacks, in fact, the method is direct, the impressions will not be identical with respect to each other thus giving each element of a single medium its own identity , unique and not repetitive, by a deposit made in a single pass, we will obtain the following results: mottling, veining, onyx, diffusion of multicolored shades with unlimited aspects of the final result, both on the choice of colors and on the choice of decorations and this, on all supports printable in serigraphy; i.e. presented in flat or shaped sheets or panels

-22604119 in three-dimensional volumes, that is to say: objects. These prints are achievable on all materials (natural or synthetic) finished or not. This method can also be used in food, subject to using authorized colored food products, example: cake decorating.

We obtain the effects of marbled, veined or onyx by stretching the colored products inside the screen using a pad and or a balyette and or a brush: the effects of abstract drawings by color diffusions in the case of colored products stamped and or projected inside the screen. The two effects can be cumulated using the different ways of proceeding mentioned above. The single deposit made in a single pass then forms a non-homogeneous mixture of different shades and shades with a predominance of the color chosen for so-called background shade.

For an artistic, artisanal and industrial exploitation, the products and materials are the following:

* A traditional screen printing screen, flat or shaped frame, metallic, wood or other, stretched with a canvas of natural fibers, synthetic or metal, -liques.

* A squeegee commonly used in screen printing.

* A pad made of natural or synthetic origins (fabrics, sponges, foams), and or a brush and or a brush with hard, semi-hard or silky bristles, of natural or synthetic origins, and or a jet nozzle expelled by air or pressure. The results of the effects obtained vary according to the choice of one or the other of these methods.

* Products, natural or colored syntheses, miscible or not, such as inks, paints, pastes, lacquers, metallic powders or not in suspension in a liquid.

The method consists of:

a) Coat the pad and / or the brush and / or the brush with a colored product of different shades.

b) To pass this coating by dabbing or spreading and or by jets on the canvas, inside the screen, on all its surface or on a limited surface.

c) Then put, inside this same screen, on one side, a certain amount of a - before marking the background. Bring another product more or less this color of a single shade, the latter of the predominant choice the shade known as the quantity of product on the opposite side, with or with a squeegee according to the conventional method, uses depositing in a single pass on the support, inking operations under the screen.

- screen-printed. Everything chosen placed before the start of an automatic adaptation, the basic principle remains the same, only the materials used will be adapted and mounted on a screen-printing machine, manual gestures being robotic.
