Paint for metal gray moire. Pattern color: moire. Defect or feature: moiré color in the fine arts

Moire color or pattern creates a visual range with the obligatory imposition of similar patterns relative to each other. For example, when two identical (usually transparent) patterns on a flat or curved surface are superimposed offset from each other.

These can be straight lines that take the form of grids or dots that are superimposed on each other with rotation or displacement.

How would it be in French

The term comes from the French word moiré - moire, it is also called moira. It means a ripple or a wave, a stripe that appears when an object is examined at different angles of incidence of light. Moire is also called the type of fabric.

Traditionally, the moire color, or rather the pattern, was associated with the type of fabric, usually high quality silk. Now ripples or waves can be seen on cotton and synthetic fiber fabrics.

The picture shows the moire effect, what color it can be - it doesn’t matter.

Structuring or thin construction

In addition to showing up on fabrics, moiré patterns are often an undesirable artifact of digital imaging and computer graphics images. For example, a similar visual effect occurs when a fuzzy image is scanned through a transparent checkered pattern.

The photo above shows a moire pattern. Lines can represent the fibers in silk as ripples or waves, they can be drawn on paper, or they can appear on a computer screen. As to why this is happening:

The non-linear interaction of systems of differently directed lines creates a real and visible moiré color or pattern of approximately parallel dark and light stripes superimposed on each other with an offset.

The photo below is a vivid example of wave visualization.

If the lines are curved or not quite parallel, more complex linear moirae are created, as in the photo of a parrot wing.
Patterns that reveal complex shapes or sequences of symbols embedded in one of the layers (in the form of periodically repeating compressed figures) usually give very interesting images that are specially created using moira groups.
One of the most important properties of all types of moiré is their ability to enlarge or stretch tiny forms of lines, stripes, dots along one or both of the stretching axes, which creates stunning 2D effects.

A general 2D example of magnification and distortion of the main pattern can be seen when viewing a chain link through another chain link of identical design. The subtle shimmering ripple design is clearly visible even from a distance.

Moire color - what is it? The photo of the garage door shows a pattern - the effect of shifting the lines of the structure relative to each other. The gate is a construction of two planes with metal strips connected with an offset.

Defect or feature: moiré color in the fine arts

Simulate colored moira with modern technologies to still achieve a high-quality image, it is quite difficult.

the very best color scheme give images of fabrics or finely constructed enclosures.

Black and white moire patterns are more malleable for experimentation. For example, the Italian constructor and designer Andrea Minini began an experiment on the construction of animal images with a graphic shifted effect.

In order to get complex shapes and depth, he starts drawing the object with a small number of basic lines.
Using Adobe Illustrator, Minini deepens the drawing in multiple directions, creating wonderfully textured moiré patterns.
Each illustration is unique and interesting for its intense expressiveness.

Waves on posters

But usually moira is considered a defect or an artifact, especially, for example, in printing full-color images, which involve overlaying halftone screens.

These are rectangular dot patterns, four of them to be exact, printed in cyan, yellow, magenta and black. There is no way to completely get rid of stains, but under favorable conditions the overall image is quite "dense", and the spatial frequency of the moiré is so high that it is not noticeable.

In fact, in the visual arts, the term means an excessively noticeable distortion-drawing, that is, the deliberate use of waves and lines. True, the visibility of moiré is not always predictable. Everything is done by trial and error, so sometimes amazing images are obtained with an unusual result, like in the picture of Brian Thomas. Moire with discoloration is shown in the photo below.

Now he's on TV

In the textile industry, moiré patterns have been used for a long time. At the royal courts, ribbons made of fabric with ebbs served as a badge of distinction.

The study of microscopic changes in the tension of fabrics, the deformation of the main weaving lattice in relation to, for example, the weaving lattice on the right, always gives new and new moiré colors and patterns.

No matter how we feel about moire, one cannot but agree that this is an interesting and mysterious visual effect that makes it re-think, study and find application in everyday reality.

moire, the name of the fabric) - a pattern that occurs when two periodic mesh patterns are superimposed. The phenomenon is due to the fact that the repeating elements of two patterns follow with a slightly different frequency and then overlap each other, then form gaps.

A moire pattern is observed when different parts of tulle curtains are superimposed on each other.

The concept of "moire" comes from the fabric moire, in the decoration of which this phenomenon was used.

A moiré pattern occurs in digital photography and scanning of reticulated and other periodic images if their period is close to the distance between the light-sensitive elements of the equipment. This fact is used in one of the mechanisms for protecting banknotes from counterfeiting: a wave-like pattern is applied to banknotes, which, when scanned, can be covered with a very noticeable pattern that distinguishes a fake from the original.

Digital Image Processing

Moiré appearance during scanning

AT Everyday life moire often appears when scanning printed images. This is because the scanner re-rasterizes an image that already has the original raster. It can be more simply represented as follows: if you take a tracing paper with one ornament and put it on a tracing paper with the same ornament, but depicted at a different angle, then the resulting ornament will differ from both the first and the second. If you impose them so that they coincide, then the first ornament will coincide with the second.

The round rosettes at the intersection of the two rectangles result in the distortion of the image seen in the first image.

The appearance of moiré in the screening process

Moire can also occur due to incorrect setting of the angles between the lines of the primary colors when screening. Both are, in fact, the interference of two sets of raster lines. There are several types of moire rosettes, by the appearance of which you can often find out the cause of the moire.

Scanning, in fact, is the modulation of signals at the nodes of the scanner grid by the brightness of the nodes of the typographic raster. AT general view the product of two modulated sinusoids (grids) with a different period of spatial oscillations is obtained. One harmonic may have a larger period equal to the sum of the periods of both gratings, which causes moiré. The second one always has a period equal to the modulus of the grating period difference and disappears because it cannot be realized at a given scanning resolution.

Paints that affect moiré

When printing with any set of inks, the most intense (dark) ink, which has a value of 30 to 70% over a large area, can give moiré. That is, if the black channel does not dominate on a CMYK photo (<10-15 %) то вероятность возникновения различимого глазом муара минимальна. Таким образом можно почти не обращать внимание на жёлтый канал CMYK фотографии. Угол поворота растра между самыми проблемными каналами должен быть как можно ближе к 45°.

When printing with “solids” (that is, with >95% infill), the concept of “screen tilt angle” practically disappears (even when it comes to photography).

An excerpt characterizing the moire pattern

“Third, I said, third,” the prince shouted shortly, pushing away the letter, and, leaning on the table, pushed the notebook with geometry drawings.
“Well, madam,” the old man began, bending close to his daughter over the notebook and placing one hand on the back of the chair on which the princess was sitting, so that the princess felt herself surrounded on all sides by that tobacco and senilely pungent smell of her father, which she had known for so long . “Well, madame, these triangles are similar; if you please, the angle abc...
The princess looked in fright at her father's shining eyes close to her; red spots shimmered over her face, and it was evident that she did not understand anything and was so afraid that fear would prevent her from understanding all further interpretations of her father, no matter how clear they were. Whether the teacher was to blame or the student was to blame, but every day the same thing was repeated: the princess's eyes were clouded, she did not see, did not hear anything, she only felt close to her the dry face of a strict father, felt his breath and smell, and only thought about how she could leave the office as soon as possible and understand the task in her own space.
The old man lost his temper: with a roar he pushed back and forward the chair on which he himself was sitting, made efforts to control himself so as not to get excited, and almost every time he got excited, scolded, and sometimes threw the notebook.
The princess made a mistake.
- Well, what a fool! the prince shouted, pushing the notebook away and quickly turning away, but he immediately got up, walked around, touched the princess's hair with his hands and sat down again.
He moved closer and continued to interpret.
“It’s impossible, princess, it’s impossible,” he said, when the princess, having taken and closed the notebook with the assigned lessons, was already preparing to leave, “mathematics is a great thing, my madam.” And I don't want you to look like our stupid ladies. Endure to fall in love. He patted her cheek with his hand. - The fool will pop out of my head.
She wanted to leave, he stopped her with a gesture and took a new uncut book from the high table.
- Here is some other Key of the sacrament your Eloise sends you. Religious. And I don’t interfere with anyone’s faith ... I looked it over. Take it. Well, go, go!
He patted her on the shoulder and locked the door behind her.
Princess Mary returned to her room with a sad, frightened expression, which rarely left her and made her ugly, sickly face even more ugly, sat down at her desk, lined with miniature portraits and littered with notebooks and books. The princess was as disorderly as her father was decent. She put down her geometry notebook and eagerly opened the letter. The letter was from the closest childhood friend of the princess; this friend was the same Julie Karagina, who was at the name day of the Rostovs:
Julie wrote:
"Chere et excellente amie, quelle chose terrible et effrayante que l "absence! J" ai beau me dire que la moitie de mon existence et de mon bonheur est en vous, que malgre la distance qui nous separe, nos coeurs sont unis par des liens indissolubles; le mien se revolte contre la destinee, et je ne puis, malgre les plaisirs et les distractions qui m "entourent, vaincre une certaine tristesse cachee que je ressens au fond du coeur depuis notre separation. Pourquoi ne sommes nous pas reunies, comme cet ete dans votre grand cabinet sur le canape bleu, le canape a confidences? je crois voir devant moi, quand je vous ecris.”
[Dear and priceless friend, what a terrible and terrible thing separation is! No matter how much I keep telling myself that half of my existence and my happiness is in you, that despite the distance that separates us, our hearts are united by inseparable ties, my heart revolts against fate, and despite the pleasures and distractions that surround me, I I cannot suppress some hidden sadness that I have felt in the depths of my heart since our separation. Why are we not together, as we were last summer, in your big office, on the blue sofa, on the "confessions" sofa? Why can’t I, as I did three months ago, draw new moral strength from your meek, calm and penetrating look, which I loved so much and which I see before me at the moment I am writing to you?]
Having read up to this point, Princess Marya sighed and looked around at the dressing table, which stood to her right. The mirror reflected an ugly, weak body and a thin face. His eyes, always sad, now looked at themselves in the mirror with particular hopelessness. “She flatters me,” thought the princess, turned away and continued to read. Julie, however, did not flatter her friend: indeed, the princess's eyes, large, deep and radiant (as if rays of warm light sometimes came out of them in sheaves), were so good that very often, despite the ugliness of her whole face, these eyes became more attractive than beauty. But the princess never saw the good expression in her eyes, the expression they assumed in those moments when she was not thinking about herself. Like all people, her face assumed a strained, unnatural, evil expression as soon as she looked in the mirror. She continued to read: 211

Unlike conventional liquid paint coatings, powder paint allows you to create many different protective and decorative effects. Let's consider some of them.

Zinc powder primer.

If the product will be used in difficult conditions and aggressive environments, it is recommended to apply a preliminary protective covering. Powder galvanizing is a great way to protect the metal surface from external influences and prevent corrosion. Powder zinc primer contains up to 80% zinc, which creates a protective oxide film. When applying such a coating, it is recommended to clean the surface by sandblasting. Any powder paint can be applied over the powder coating.

Glossy or matte powder coating.

Powder coating allows you to achieve different degrees of surface gloss. This effect is created due to the different content of transparent powder particles contained in powder paint. By this indicator coatings are divided into several categories:

Gloss - 70 to 90% gloss
Semi-gloss - 40 to 70% gloss
Semi-matt - from 25 to 40% gloss
Mat - 10 to 25% gloss
Deep mat - up to 10% gloss

The choice of one or another degree of gloss, it is better to do holding samples of various coatings in your hands, since, for different manufacturers, the degree of gloss may vary.

Coating Shagreen.

This coating has excellent decorative properties. In addition, shagreen hides minor defects in the painted surface. The shagreen coating is similar in texture to the peel of an orange or lemon.

This effect is created due to special particles that swell during polymerization and form a special texture of the coating.

Examples of shagreen coating.

Antique finish.

In addition to excellent protective properties, powder coating can give the product a wonderful and unique look. One way is to apply a layer of paint imitating antique copper, silver or bronze. Currently, many manufacturers of powder paints create real masterpieces that allow you to give any metal the nobility and mystery of antiquity. Such a coating is often used in the creation of decorative products. For greater stability, it is recommended to cover such coatings with a protective layer of transparent powder varnish.

Moire cover.

Moiré coating is perhaps the most beautiful of powder coatings. In texture, moire resembles fine sandpaper. The colors of the moire coating can be any.

The most preferred colors for this type of coating are black or white. Moire coating is often used to create unique interior metal products. Like shagreen, moiré coating is able to hide minor defects on the surface of a metal product.

The specialists of the company "Neman" perfectly mastered the technology of applying polymer powder coating both to finished doors and to non-standard designs. To do this, there is everything you need - knowledge, experience, strength and desire. Polymer coloring is a waste-free and clean technology, allowing to obtain high-quality decorative-protective and decorative coatings.

Note that appearance is formed from polymer powders applied to the painted part of the fabric of the product. Next, heating is performed, and the product is kept at a certain temperature for several minutes. A low polymerization temperature allows staining glass and metal using this technology. In the last decade, this technology has become very popular and is gradually replacing traditional ways applying paint coatings.

One of the finishing options offered by Neman is Moire. What is this coverage? It's a finish front door offering special powder coating structure. So, on the canvas upon completion of the work there will be a special pattern. Figuratively speaking, moiré can be compared to the effect that sandpaper gives. The main advantages of this type of steel are: practicality, aesthetics and versatility. Typically, such products are used in cases where you want to get the most practicality possible. It is also effectively used to hide defects in the outer part of a metal door.

What are the benefits for a consumer who chooses moiré coloring?

High resistance to aggressive environment (alkalis, acids, organic solvents);
Resistance to mechanical stress;
Increased adhesion. In this case, the adhesion of paint particles to the treated surface is 500kg/nm;
High corrosion resistance;
Environmental friendliness. The paint does not contain organic solvents and other types of volatile substances.

The main meaning of the staining method is to spray powder paint on a pre-cleaned metal coating. You need to know that paint particles receive an electrostatic charge, which allows the particle to stick to an article that has the opposite charge. Particles that have not had time to settle are captured in the spray chamber and can be used again. After that, the product is placed in the polymerization chamber for subsequent baking of the paint at a temperature level in the range from 180 to 200 degrees Celsius. Thus, a reliable, high-quality and safe for a person decorative and protective design is created on the canvas. Metal doors with Moire coloring can be used not only for installation in apartments, cottages, but also at industrial facilities.
