Creating surfaces with unique patterns and its process

The subject of the invention is a process to create materials with unique patterns. Its uniqueness is that the pattern, which is made up of small numbers, letters, and other symbols and their shade varieties, appears as a uniform colour or shape from a distance.

Various printing and pattern types and their corresponding, long-established technologies for textiles, shoes, and possibly other impregnated and coated materials are known in the market, which have gone through substantial development. To outline the field, let us provide a brief list of some of the patented processes. The description titled "PRINTED TEXTILES WHERE PATTERNS ARE FORMED ON NON-CHANGING PIGMENT BASES AND A PROCESS FOR PRINTING" under Patent Number 26776 creates shiny and dull surfaces with a mechanically adequate solidity to which, among others, metallic powder is added. The description titled "MANUFACTURING MULTI-COLOUR MIXED

COLOURS IN WOOL BY PRINTING" under Patent Number 27483 also discusses patterning and colouring, but it specifically targets the whole of the wool and the painting and marinating processes in various stages of handling. The procedure discussed under Patent Number 138359, titled "A manufacturing process for gravure printing rolls for reproducing single or multicolour half-tone patterns by photo mechanics for textile printing" is a much more modern process than those mentioned above. Its advantage is that single or multicolour half-tone patterns can be reproduced by gravure printing rolls in a photomechanic procedure. We consider the above examples relevant in that they are processes for printing textiles and other materials; however, in our opinion there is no solution currently among the patented inventions or on the market that is similar to ours or that would produce a similar surface.

Hence, the object of the invention is a process that uses a sublimation machine to manufacture the designed small patterns, which in turn create a larger symbol or pattern, or possibly a colour. It is important to note that our process can be applied to any textile, and that the printed symbols do not exceed 3 mm in size, covering the entire area of the material, creating a material that is not painted but patterned. The final product creates a unique impression by consisting of small patterns in such a size that from a distance it appears as a uniform colour, while up close it is visibly made up of small symbols, letters, or possibly numbers.

The problem to solve, in our consideration, was to create a special product that gets its unique effect not from its coloured base material, but solely from its patterns and the unique size of that pattern.

We deem it a beneficial solution for our purposes that the small patterns are applied on the material by a design where changing the colour shades will create a larger pattern, which also only appears as a uniform pattern from a distance. As the first step of the procedure, we clean and degrease the selected product, after which the designated symbols, characters, or letters are applied by screen printing or printing to the surface in a size no larger than 3 mm. Patterns are implemented in accordance with the desired larger pattern or colour shades. Finally, the material is dried and the cutout template is created and compiled in accordance with the product.

Thus, the aim of creating a unique pattern is to achieve a special visual effect. It can be applied primarily to sports apparel, but also on shoes, coats, and other clothing materials, or on stickers and posters. Screen printing is essential in order to achieve longevity of the patterns.

Another beneficial solution of our process is the application by a printer; however, considering the flexibility of the base material, this can only be implemented by using an accessory material, and may involve a high risk ratio and high costs. The procedure may be applied to flexible and rigid materials alike, meaning textiles, fabrics, metal, wood, and paper.

To help the reader understand the subject of our intervention, we provide a schematic drawing of one of the products to be manufactured with this process. Diagram 1 : Coat with a unique pattern and colour shade created by small characters.

Diagram 1 demonstrates that the clothing appears to have a uniformly coloured surface from even a distance of 2-3 metres, while from up close it is apparent that it is made up of tiny character patters. To produce these characters, the easiest method, as mentioned above, is screen printing. On the left in the diagram, 1 a pattern made of specific small characters is displayed, which is also suitable for colouring, while on the right there is a close-up of a section of the coat's material where 2 the characters that make up the pattern or colour are visible to the naked eye. These characters can be symbols, letters or numbers.
