CS236975B1 - A method of designing patterns, especially textiles - Google Patents

Abstract

The invention relates to the creation of design patterns, especially textile, intended mainly for textile printers. Objects forming design motifs, or design motifs, created on a translucent or transparent surface, are transferred by one or more light exposures, contact or projection onto a substrate, the surface of which is sensitive to light, after which this substrate is chemically treated so that the resulting exposed image becomes visible and no longer changeable by light. Multiple exposures are carried out when changing the position of the substrate, the motif, or changing the motif, or by a combination of these options.

Description

The invention relates to methods of designing designs, in particular textiles, performed using photographic and reproduction processes and techniques in novel combinations.

Industrial textile design, regardless of the technology of transferring the pattern to the material or the representation in the material, is most often drawn or painted, using a pencil, pen, brush, etc.

The designer of textile designs seeks and creates in the form of realistic, stylized or fantasy shapes, combines and varies, tries to derive various groupings or conversely dispersing motifs of their sorting, blending, rotating, using colors throughout the realizable palette, creating soft and contrasting color compositions etc. .

The practical application of the use of innumerable wealth of variations encounters some difficulties. For example, multiple use of the same element requires drawing the element many times, using gradation of the element assumes its laborious enlargement or reduction, converting positive shape to negative or vice versa, means drawing the same theme again with the same handwriting. safely identify, etc.

These and many other demanding work phases can only be successfully handled using special computer devices and similar, very expensive devices such as SCI-TEX.

The hitherto known use of photoprocesses in designing pattern designs, in particular textile, is very small and is limited primarily to creating soil patterns, the simplest and common photo technology, followed by drawing or painting the main motifs on the soil of the future pattern design.

SUMMARY OF THE INVENTION It is an object of the invention to provide a simple, efficient and inexpensive method of creating patterns, in particular of textile.

Essentially, the inventive method for forming patterns, in particular textile fabrics, is accomplished by transferring the pattern motif objects or pattern motifs formed on the translucent or transparent planar formation to the substrate by one or more light exposure, contact or projection, the surface of which is sensitive to light, after which the substrate is chemically treated so that the resulting exposed image becomes visible and no longer changes in light.

The multiple exposure is preferably performed when the substrate, motif, or motif is changed, or a combination of these.

The invention enables the author to process a negative motif or a motif of the subject character not only arbitrarily into a positive form of size and saturation graded, but especially to display this motif with angular or lateral displacement as well as possible blending, and especially by combining with other motifs fixed on a solid and portable mat in true color and size.

Once a negative or motif of the object in question can be used for multiple combinations and for multiple purposes. For example, a flower motif in a reduced size and in an appropriate layout in the surface will give the resulting design for a textile dress pattern, the same motif heavily enlarged and otherwise rhythmical can create a decorative fabric or wallpaper design without the same shaping defect in terms of aesthetics or functionality.

The whole process is economically and less time-consuming compared to classical drawing of design designs, it brings quickly new qualitatively results and thus significantly enriches the expressive means of creative design work.

Pattern motifs created on a translucent or transparent planar formation are those obtained either by photographic scanning, ie photographic negatives, or by drawing, painting, cutting, laminating, covering, scratching and other similar methods on a planar formation such as glass, film, paper, etc. .

Pattern motifs are all those in which their silhouettes can be transmitted by light with internal contouring, contact or projection, such as flowers, foliage, grasses, twigs, fruits, sand grain clusters, small metal particles, screens, grids, wire formations, perforated objects, buttons, buckles, jewelry, etc.

With multiple exposures on the same surface, changing the themes can produce an image that alternates or blends them, regardless of whether individual exposures are only contact, projection only, or a combination of both exposures.

By chemical processing is meant a process that creates and stabilizes the image on the substrate, or, depending on the creative intentions, motif shapes or even tones the surface of the substrate or otherwise complements it.

The resulting image, most often on paper, can be combined and complemented by motifs of other similarly created images, such as montage and gluing, and can also be supplemented by painting or drawing.

The possibility of making more exactly identical originals enables their use in the tendering of designs at several places, as well as in particular for subsequent drawing of the pattern of the pattern, ie drawing of the pattern into repetitions in dimensions enabling the production of final goods by the given technology. Pattern shapes - pattern can be scanned not only on a paper backing, but also on a flat film, which in many designs or production technologies creates a substantial basis for lifts of individual shades.

When working with paper for color photography and with the so-called color head on the magnifying machine, with the possibility of choosing the color light, individual expositions of motifs can be tinted in various colors or the selected shape solution of the pattern can be converted to another color solution.

In black and white photo paper, the resulting image in saturation degrees can be subsequently toned in many different colors according to known recipes.

Possibilities of unusual merging and blending of motifs are that it is possible to combine the created motif with motifs of real objects, such as the raster-projection structure to be transmitted to a sensitive substrate on which various parts of the vegetation are suitably placed. In this case, the resulting image is the shapes of vegetation on the raster surface. The resulting image can be freely adjusted before exposure4

236 975 shifts of negative and subject motifs, complemented by other elements-motifs, such as shapes cut from paper., Parts of vegetation, wood or metal fragments, etc. It is therefore possible to search for various shape and compositional combinations and fix only the suitable ones.

Example 1 ^

A thin and irregular layer of oil is applied to the transparent or translucent film with a brush, spatula or cloth, and this area is lightly brushed over with a brush paint that adheres to the film only in places with a smaller oil layer, creating an interesting texture. difficult to create.

By this process, a large number of scattered, aligned, agglomerated, sparse and dense structures can be quickly and minimally formed, and can be further developed, for example, by scraping, grinding, imprinting, or the like, or oil-free structures.

From the negatives created in this way, the selected type is copied to the photopaper in the whole area. The original is in 1: 1 scale and the structure drawing is negative.

Example 2 ^

From the negative produced according to Example 1, the structure is contact-copied onto a flat film, thereby obtaining the structure in a positive form - a new negative. The result of the process is a 1: 1 picture with a positive drawing of the structure.

Example 3 *

On the negative produced according to Example 1 or 2, either opaque objects, possibly flowers or other plant elements, etc., or other foils with drawn motifs are placed, and exposure to photopaper creates an image of the objects - motifs in the size of the structure in size 1 : 1.

Example 4 * 236 975

The negative produced according to Example 1 or 2 is contacted copied onto the same photo paper two or more times by rotating the negative by a selected number of degrees (1 to 180 °) at each subsequent exposure.

Optionally, double or multiple mirror exposures can be used.

Example 5

The negative, produced according to Example 1 or 2, is cut into strips, wheels, concrete and fantasy shapes by shearing, from which the pattern is assembled and exposed directly to the photographic paper under red light only after the final pattern has been found.

Example 6 _X

A selected portion of the negative structure made according to Example 1 or 2 is placed in a magnifying apparatus and, after a selected degree of enlargement or reduction, the image is exposed to photographic paper.

The enlargement or reduction of the structure can be carried out for the negatives made according to Examples 1 and 5.

Thus, sixteen different designs can be made from a single basic structure using the above methods. The resulting image on photo paper can optionally be supplemented by direct drawing or painting.

Example 7

The drawing of the structure of Example 1 is replaced by more specific arbitrary motifs drawn or obtained by photographic techniques including for designing a suitable, classically obtained negative. It is also possible in this example to utilize all the variations described in Example 1.

Example 8χ

The methods set out in Examples 1 to 7 are complemented by exposure to a third motif, thereby increasing the variability of the themes: a motif on a foil, such as a strip, in contact with photo paper, a second motif - subject, e.g. for example, a screen transmitted by the light projection of the enlarger.

238 975

Films with raster or motifs can be replaced by flat objects with a shape division determining the light transmittance or impermeability, for example a metal grid, colored nylon mesh etc.

Optionally, the motif obtained by the light projection can be shaped by the use of embossed glass such as building glass, interior glass, lens glass, strip glass, ornamental glass or the like, placed either directly on photographic paper or under the motif itself.
