How to solve the discoloration of inkjet canvas?

The upper layer is transparent and high in texture, which can be very waterproof, anti-ultraviolet and anti-fading.

Texture refers to the texture structure of the object surface, that is, various criss-crossing, uneven, rough and smooth texture changes, which express people's feelings about the texture characteristics of the design object surface. Generally speaking, texture and texture have similar meanings. As for the form factor of design, when texture and texture are linked together, on the one hand, it is felt by people as a form of material, on the other hand, it is reflected in the creation of new texture forms through advanced technology. Different materials and different technological methods can produce various texture effects and create rich external modeling forms. Texture in painting: In painting, texture is the product of the combination of material and expression, and it is the organizational structure and texture of a picture created by the author according to his own aesthetic orientation and feelings about the characteristics of objects, using different materials and materials and using different tools and performance skills. The surface of any object has its specific texture changes, and the magical visual feeling presented by this specific texture change is exactly the texture effect pursued by painting art. The aesthetic value of texture in painting art can not be underestimated, and it has aesthetic characteristics that are difficult to achieve by other means of expression.

Watercolor painting not only has gorgeous colors, elegant and fresh styles and rich forms of expression, but also has the indescribable, natural, realistic, magical and wonderful artistic effect that fascinates painters most. The effect of this blending of water and color is the natural image presented by the author's subjective and objective, intentional and unintentional creative activities. The special visual language presented by this object representation feature is the unique language charm of watercolor painting, that is, the texture beauty of watercolor painting.

Based on teaching and creative practice, this paper discusses the texture beauty of watercolor painting from several aspects.

First, the beauty of natural texture and artistic texture.

There are many kinds of nature and everything in the world, which is the most basic element of visual image. Life is the source of artistic expression and artistic creation, so is watercolor landscape. Colorful sky, boundless sea waves, ancient walled wooden houses in cottages, misty dreams in the morning, winding ancient roads, wonderful rocks, charming sunshine, misty rain and fog, mottled vicissitudes of dead trees and vitality of seedlings all show the beauty of wonderful and changeable natural texture.

There is a layer of skin on the surface of an object. In nature, it has a variety of organizational structures, including smooth and bright, rough and mottled, light and soft, and heavy and hard. The surface texture changes of these objects make them form an objective natural form, that is, texture, which gives people different visual feelings. Texture is not all beautiful, only in a specific space, a specific environment, a specific light, can present a certain sense of beauty. It is from here that the painter draws artistic inspiration, applies this natural texture feeling to visual language expression appropriately, and creates artificial artistic texture beauty. For example, American painter Wise showed mottled paint, broken walls, rough fences and so on. Among his works, such as The Mill in Winter and The Apple Barrel. These images may not have any aesthetic feeling in life, but when they are artistically treated by painters, they present a brand-new artistic beauty, thus expressing specific aesthetic factors and significance. No matter what the form and content of watercolor painting is, it is not a simple reproduction of life, let alone a pure objective imitation. It is the sublimation and expression of the painter on the basis of his life experience.

Rodin once said: "The nature seen by artists is different from that seen by ordinary people." The reason is worth pondering. Those ordinary landscapes, once they become the objects described by artists, are endowed with special significance, that is, to express their feelings through landscapes, so that their aesthetic concepts and spiritual pursuits can find an object to express themselves. In this particular situation, people and things, feelings and scenery are integrated. Once the natural texture is dissolved into the painter's emotion, it will stimulate the painter's creative passion and make it the object of the painter's "use topic". They are used by painters to create vivid and ever-changing artistic textures by using various materials, tools, techniques and stunts, thus becoming a new visual language. For watercolor painting, the unique tools make it unique in texture creation, which is unmatched by other paintings. Of course, this artistic texture made by various means is a subjective texture of the painter. Even if it is spilled at will, it will leave the painter's subjective feelings about the object, which makes the artistic texture more aesthetic in a sense.

The application of artistic texture in artistic practice can not only enrich the expressive force of art, but also increase the vividness and interest of the picture. When facing the majestic Taihang Mountain, layers of rocks and axe-shaped stone marks make us feel the inner touching power of nature. When you are in the ancient town of Jiangnan water town with fireworks in March, in the faint morning fog, the water drips seriously, the air is beautiful and the drizzle is silent, giving people a kind of light and meaningful hazy beauty. This is not only the beauty of the appearance of nature and objects, but also the deeper artistic beauty behind these appearances and visible textures. All kinds of natural textures are related to people's psychological imagination. Converting various natural texture patterns into painting language as visual information to produce artistic texture will undoubtedly enrich and expand the expressive force of watercolor art and make the expression and psychological effect of watercolor highly consistent.

Second, the texture beauty of concrete realism

As the basic language form of visual art, texture has the same functions of modeling and expressing emotion as color and line. In figurative and realistic watercolor painting, texture can reproduce the rich and changeable features of the surface of the object, which has unexpected modeling effect. Texture is widely used in traditional realistic watercolor painting. Realistic watercolor masters like William, Turner and Sargent can not only skillfully control the tool expression of watercolor painting, but also break through the shackles of classical programs in watercolor painting and boldly explore and expand the application of special techniques and texture effects in watercolor painting. Hunter, a British watercolor painter, used the special technique of splashing for the first time in the huge watercolor landscape in November, which made the water and color on the screen interact, thus accidentally discovering the opportunity and skillfully using the freely growing graphics of pigments to paint. This is an extension and change of traditional watercolor painting, in which local texture is used instead of hand-painted marks, thus finding a new carrier form of emotional release in watercolor painting creation. The watercolor works of American watercolor master andrew wyeth and Swedish painter Zorin are the perfect combination of traditional and modern concepts. They absorbed some technical advantages of oil painting and printmaking for our use. On the basis of keeping the watercolor transparent and pure, they adopted touch-up spray dyeing method, oil-water separation method, scraper method and rubbing method. The texture effect produced by these stunts not only enriches the connotation of watercolor painting, but also expands its extension. Wang Zhaomin is a famous watercolor painter in China. He devoted his life to the pursuit of concrete realism. His Still Life Series, Kapok and many other works are the most typical works with texture beauty in contemporary China realistic watercolor works, especially his painting method of making texture foundation on watercolor paper, which makes watercolor appear three-dimensional and profound. In the use of color, he absorbed the heavy feeling of China stone reliefs, brick reliefs and grotto murals, with both skills and philosophy, showing the beauty of simplicity, smoothness and massiness.

Texture can not only show different textures of objects, but also make the picture show various visual effects. Different texture contrasts can make people feel different aesthetic implications. For example, the salt sprinkling method in watercolor stunt is to use the characteristics of salt particles dissolving in water to sprinkle salt particles when the picture is wet, and the salt particles ooze color to form small white spots like snowflakes, just like flowers dancing like snowflakes. For example, in flower still life painting, dropping a few drops of water on the background at will will immediately break the plane state in the foreground and become vivid, blending with the flowers in the foreground. Similarly, there is a certain isomorphic relationship between the texture of pigment oozing and the growth form of branches. Using natural infiltration to express dense branches adds natural interest to the picture.

Third, the texture beauty of abstract freehand brushwork

The so-called "abstract freehand brushwork" and "figurative realism" in watercolor painting are relative concepts, which are independent and interdependent, and can also achieve complementarity and harmony on the same picture under certain conditions. Concrete is the main thread of emotion and nature, and abstraction is the hub of rational thinking. The abstract and freehand texture in watercolor painting has unique advantages that other paintings can't match. The character of water is clear, bright and flowing, and the characteristics of color are changeable, mysterious and strange. The blending of water and color constitutes a glittering and translucent world, a dripping world and a rapidly changing world. Watercolor produces various magical and wonderful texture effects in the process of flow, collision, fusion and decomposition. Although it is difficult to see the concrete image in line with the reality of life, it has brought us many related visual associations. We seem to see the germination of biological evolution and the trajectory of celestial movement, which seems to be the flicker of cells, algae, nebulae, waves, forests and flowers in a chaotic state. This special beauty of visual texture emphasizes the visual visualization of the spiritual world, and seeks a subconscious thing in symbol and association, thus achieving the transcendental realm of "elephant is invisible" and "things forget each other". He Cheng, a famous Chinese-American watercolor painter, creatively explored an abstract watercolor expression method with a unique oriental artistic style on the basis of the image expression of China's freehand landscape painting. His representative works include Autumn Colors, Bai Lianhua and Elephant Invisible. In terms of texture performance, it is integrated with splashing, alluvial, rubbing, covering, rubbing and sketching to achieve the goal of "although someone makes it, it is natural".

In a word, watercolor painting is very broad in the way of texture expression, which can be "writing after meaning" and "writing after meaning", thus forming a "thousand words" of watercolor painting. Seeking the beauty of artistic texture from the beauty of natural texture is the real feature and advantage of watercolor painting. It can not only vividly express the image with the help of texture, but also make the picture hazy and ethereal with the help of texture; It can not only contain abstract meaning in concrete, but also produce truth and agility in abstraction. Excavating the inherent potential of watercolor texture expression from the aesthetic exploration of artistic language will continuously endow watercolor art with new connotations, open up new contexts and form new styles.

Fourthly, the texture in three-dimensional composition

In the three-dimensional composition, texture refers to the texture of the material surface, the tactile and visual touch given by the structural organization. According to the source, it can be divided into the texture of the material itself (Japanese wood grain, marble grain, etc. ) and artificially processed textures (such as wood-based panels imitating wood grain, artificial stones imitating marble texture, and textures formed by the combination of various materials, etc. In addition, textures can be divided into tactile priority textures and visual priority textures according to different human feelings. What can be felt through the touch of human skin is called visual priority texture. The texture in stereoscopic composition is often a comprehensive texture of touch and vision, and both visual feeling and touch can be obtained. Touch is a special feeling of human body. Various external stimuli (cold, hot, soft, hard, smooth, rough, etc.). ) are transmitted to the brain through nerve endings distributed in the skin, which makes the human body have a comprehensive feeling, which is more complicated than hearing and vision. For example, an experienced ceramist can judge the quality of clay and porcelain fired with it by touch. Therefore, touch is the main means to bring us a sense of texture. Through the sense of touch, we can feel the cold, hot, soft, hard, slippery and rough properties of objects. Another kind of texture comes from vision. For example, if we drown in the sea from high altitude, the blue sea surface will convey the texture of the sea surface to us through vision. Another example is standing on the mountainside and watching the sea of clouds. Although we can't feel the sea of clouds through touch, we can still feel the special texture of the sea of clouds through vision. Different textures will bring different psychological feelings to people. For example, marble texture expresses luxurious and elegant artistic conception, while cloth texture conveys cordial, soft and simple artistic conception. At the same time, different textures will produce different glossiness and surface impression because of the different spatial distribution of reflected light. For example, the delicate and bright surface has strong reflective ability, which will give people a light, lively and cold feeling; Smooth and dull surface, due to less light reflection, will give people a subtle, quiet and simple feeling; Rough and shiny surface will give people a heavy, messy and heavy feeling, because there are many reflected light spots; Rough and dull quality will make people feel vivid, steady and distant. In the three-dimensional composition, texture does not exist independently, but belongs to the detail treatment of modeling, which is equivalent to the material selection and surface treatment of products. Texture has the following functions in three-dimensional composition: ① Texture can enhance the three-dimensional sense. For example, the surface and side of a shape are treated with different textures, which can enhance the three-dimensional sense and layering of the shape. This function of texture is determined by the shape of texture and the relationship between segmentation and configuration. ② Texture can enrich three-dimensional expression. Different textures will present different expressions and features. In order to give full play to this function of texture, we often put texture in the part that we often see in the line of sight when we make three-dimensional composition. ③ Texture also has intelligent significance. In other words, different textures will remind us of their functions and uses. Special textures such as bottle caps, knobs and switches will guide us to use our bodies. In order to give full play to this function of texture, we can arrange texture to be used in the parts that we often come into contact with in three-dimensional composition. Texture composed of similar materials can produce harmonious and unified effect, but monotony and rigidity should be avoided; However, the textures of different materials will produce various effects, but attention should be paid to avoid disorder. To sum up, in three-dimensional creation, it is necessary to choose the appropriate texture to express the work. At the same time, the harmony of texture, modeling and color is also the guarantee to create good three-dimensional composition works.

V. Classification of texture

Texture can be divided into natural texture and creative texture.

Natural texture: natural texture is a natural realistic texture, such as the texture formed by unprocessed wood and stone.

Create texture: create a realistic texture artificially created by the texture stone, that is, the surface of the raw material is processed and transformed, which is a texture form different from the original touch. Through carving, kneading and other processes, and then arranged and combined.

Texture product is an indispensable factor in graphic design, product design and architectural design. Proper use of texture can make the design more attractive. In addition, texture can also be combined with repetition, gradual change, emission, change and contrast.

At present, a special texture effect made of gold foil is popular in the market, and it is quite promising to display decorative paintings indoors. In many lobbies, including the hotel design area, the effect of gold foil texture painting under the transparency of lighting can be said to be unique. Jordon Art Consultant (Shanghai) has designed special texture paintings made of gold foil in the public areas of many star-rated hotels.
