Description

[Detailed description of the invention] The present invention relates to a method of making a reproduction of an artistic work.

Before the present invention, artistic work had its own characteristics,
and whenever it is done by the master's skill;
Artists or printmakers worked on cloth or paper to produce valuable original works.

However, it has been practically impossible to perform three-dimensional printing without always incurring a lack of originality when dealing with paintings or sculptures. Artists usually
In view of the insurmountable technical complexity, prototypes or models cannot be created by individuals. Due to the inconveniences of the traditional method, an artist or printmaker creates his work on a wax surface and then makes the required number of copies, giving each copy an artistic touch and the artist's original work. In order to be able to maintain the details, special techniques were required to be devised.

The technical object of the invention is to provide the necessary steps for carrying out manual work directly on wax plates made by artists or printmakers, as well as paper, cloth, plastic materials or other materials for this purpose. In view of the combination of successive steps up to and including subsequent press printing on any other suitable surface,
It is new and original. In view of the above, the present invention
This proves to be a significant advantage in obtaining artistic works of continuous and uniform quality.

For this purpose, a series of steps were carried out which, in combination with each other, could not be expected by any conventional technology in terms of the originality of the technique for producing three-dimensional printing in paintings, sculptures, etc. We provide a new method that has never been done before. One of the objects of the invention is to provide a method for making a reproduction of an original work of art produced directly on wax board. Reproduction can be done with ink, whereby the engravings or designs are printed in color or ink, or without the use of ink or the like, whereby they can be reproduced by the artist on waxed board. The result is a relief on a dry white background that reproduces the details. Another object of the present invention is to provide a wax composition which can be used to create works by artists or printmakers directly on a board comprising it.

The composition of the wax is important and constitutes one of the additional features of the invention since it must possess certain properties without which effective results in print quality cannot be obtained. . Yet another object of the invention is to apply this inventive technique to known printing methods for obtaining artistic works.
For example, it is to provide a method that can be combined with lithography, engraving, silk rubbing color printing, etc.

These and other objects of the present invention will become clearer as the detailed description of the invention proceeds, as will become clearer as the detailed description of the invention proceeds. This requires carrying out a series of sequential steps in which various materials and special techniques are used, as described below.

(a) Wax formulations are made by mixing various waxes.

The formulation is further mixed with turpentine and graphite powder. These components are needed to impart a small amount of electrical conductivity to the solder. This molten preparation is poured into a box to make a board approximately 2C7n thick. When the plate is formed, it is planned so that it has a uniform thickness and its surface is smooth, and for this purpose an additional amount of solder is used, thereby providing uniform dimensions. A board with a smooth surface is produced. (b) The artist engraves on the wax plate at room temperature. To create the relief effect, the wax is melted in a separate device (water bath) and added using a paintbrush. If the wax is completely melted. If not understood, it can be molded as a putty or sculptural consistency. Needless to say, the wax can be worked with any shaping and sculpting equipment, and furthermore, some additions can be added to produce special artistic effects, thus: For example, a pattern can be engraved on the fabric; for this purpose, the fabric is impregnated with an additional amount of molten wax and then fixed to a wax plate. It is clear that the use of warm tools facilitates engraving. (c) A thin uniform coating of conductive material is formed on the surface engraved or shaped by the artist to impart electrical conductivity to the solder plate. The material used is a powder such as silver or graphite powder. Remove excess powder with a brush.
or removed by an air compressor. The graphite-treated braze plate is then subjected to an electrolytic bath, which forms a copper coating on the graphite-treated surface. The thickness of the coating is chosen appropriately, but it should be sufficient to fix the molded body of the work created by the artist. This electrolytic bath is
Conventionally, it consists of an aqueous solution of sulfuric acid and copper sulfate, which is supplied at a maximum voltage of 2V for a time selectable between 12 and 2Sf. The reason is that if higher voltages are used, the copper thin film becomes brittle and therefore
This is because it cannot be removed from the solder plate. The thin copper film is therefore required to be flexible, which means that the variable voltage must be controlled between certain limits. → The copper film formed during the electrolytic coating process is removed by using the above.

r) Applying a tin coating using a blowpipe with tin powder to the copper surfaces that were not in contact with the solder in preparation for the subsequent process step of said copper coating.

(The tin coating step is to fix the lead to the copper in a later process.) 3) The copper coating is removed and placed inside the box, after which the melted lead and other substances, glass Fibers or any plastic material by means of which a cast can be formed are poured onto the copper coating, thereby forming a cast with the purpose of thickening the copper film. It is formed.

Pouring is usually done with molten lead, which
Pour directly onto the tin coating until a lead coating with a uniform thickness of about 1Crf1 is formed.

When the lead is poured, care must be taken to constantly heat the box with the copper coating, thereby ensuring that the lead adheres properly to the copper.

h) The composite plate formed by the above coatings is:
It is cooled so that the lead solidifies.

The composite board is removed from the box and brushed and modified on the side where the lead is placed, so that the lead coating has a uniform thickness with precision on the order of millimeters. It is recommended that you have it. (1) The composite board made according to the previous step is installed in a copper plate printing machine with the board.

The composite board is placed with its copper coating facing up, i.e.
exposed and placed on the plate of a copper plate printing press. The material on which the printing is to be performed, e.g. cloth, paper or any other material,
is placed on the composite board with the engravings, and on top of the paper or other material used a soft covering piece, for example a thick velvet piece or a rubber plate, is placed. Next, the copperplate printing press is started, and the printing press
The sheets are drawn together with the velvet or rubber sheet and passed under pressure between the two rollers, thereby applying the pressure to the velvet or rubber sheet and the paper. and immerse into the engraved copper surface. In this way, the engraving can be printed on paper, or on cloth, or on any other material surface used. If ink is applied to the copper surface, this will print the paper.

Furthermore, an artist or printmaker may color the copper surface with inks or pigments to obtain a color imprint. Next, examples of the present invention will be described.

To carry out the process described above, conventional wax compositions or other suitable compositions for carrying out the process can be used. However, extensive practice has led to the development of special wax compositions which give excellent results with the aforementioned method. It can be said that if this developed composition is not used, Method I cannot function effectively and produce excellent results. Such compositions form part of the invention and are as described below. Yellow wax (Birgen) 43.03% candle wax
23.65% paraffin
10.75% turpentine 6.45
% Graphite Fine Powder 16.12% The wax shall have the following properties: (1) The wax shall:
It should be malleable and ductile.

(2) The wax must not undergo any appreciable dimensional change at room temperature and must not be brittle.
(3) When melted, it should be processable on the plate according to the temperature controlled by the thermostat, and the solder should provide a relief effect; The wax must function like a fluid ink, drypoint or dry paint brush.

(4) when melted, the wax is extremely thin;
It should be sufficiently fluid to impregnate objects with a barely visible film.

(5) The wax must not form bubbles when melted.

(6) The wax should be easily processable with sculpting tools at room temperature.

The wax should have a spreadable consistency with the warmth of the hand. (7) The graphite fine powder should be a conductive element.

The method described with steps (a-1) above may, of course, also include the use of other moldable materials such as plaster, clay or putty or thermoplastics which, when engraved, will last indefinitely in place of the wax. This can also be done by using something that can maintain the engraving.

The present invention can also be used in combination with traditional techniques such as lithography, engraving, and silk rub color printing.

Although the present invention has been explained above based on its recommended embodiments,
It must be understood that any modifications of the invention as described herein and as claimed in the appended claims are necessarily included within the scope contemplated by the invention.
