Is there anything to pay attention to when painting the wall? Please give me some advice.

Colored fountain pens, markers and brushes: used for drawing and coloring.

Gold, silver, black and white pen, duckbill pen: used to describe the details, outline and highlight of objects.

Combination brush and spray pen: used to draw the background and paint in a large area.

2). Drawing instruments

Drawing tools should be accurate, precise and high-quality products, and small errors are good drawing tools.

Ruler, T-square, curve ruler, tape measure, magnifying ruler, graduated ruler, triangular plate, groove ruler (homemade, not available in the market), cutting ruler, universal plotter, big compass, etc.

3). Other electrical appliances

Coloring utensils: palette, plate, pen. Color code, tracing table, drawing table, tools (including paper cutter, various art knives, carving knives and adhesive tape).

2. Applied materials

With the rapid development of industrial design specialty and science and technology, design materials are changing with each passing day and there are many varieties. Designers can get twice the result with half the effort as long as they pay attention to the information of materials, select materials in time and apply them to the design.

1). Pigment

Watercolor pigments, acrylic pigments, poster colors, Chinese painting pigments, fluorescent pigments, colored inks, brush strokes, dyes and photographic transparent colors. 2). Paper

There are a lot of paper for design, which is particularly miscellaneous, and all kinds of paper on the market can be used. When using it, look at your own needs. But paper that is too thin and soft should not be used. Generally, drawing paper, watercolor paper, gouache paper, white cardboard (double-sided card, single-sided card), coated paper and tracing paper can be used. There are imported Mike pen paper, cold-pressed paper and hot-pressed paper for illustrations, synthetic paper, colored cardboard, transfer paper, pattern transfer paper and so on, all of which are ideal papers for painting. But each kind of paper needs to match the characteristics of tools and present different textures. If the material is not selected properly, it will cause unnecessary binding and reduce the painting speed and performance effect. For example, a flat-coated microphone pen cannot draw on smooth cardboard and high-permeability paper.

3. Several materials and painting characteristics

1). Watercolor pigment

Watercolor pigment is a traditional material for drawing design drawings, which has been used to this day. Watercolor pigments are mostly transparent. To complete the design simply and quickly, just take lines as the main body and then paint them with watercolor colors. For example, pencils are light and pens are light. Watercolor can enhance the transparency of products, especially in the texture of transparent objects such as glass, metal and reflective surfaces. Transparent and reflective surface is very suitable for watercolor expression. When coloring, go from shallow to deep, try to avoid heavy pen, and do it in one go. When painting brown or dark green, you should be careful not to dirty the picture.

2). Poster color

Poster color has a considerable concentration and strong hiding power, which is suitable for thicker methods. The strokes can overlap. In the case of emphasizing large-area design, or emphasizing the intensity of primary colors, or there are many turning points, it is most appropriate to draw with advertising colors. Advertising colors should not be too strong or too light. If it is too thick, it will be sticky, it will be difficult to pull the pen away, and the color layer will appear too dry and crack. If they are too thin, they will spoil the beauty of the picture.

3). Mike pen

The Mike pen is a versatile tool. Its advantages are convenient use, quick drying and high painting speed. Nowadays, it has become one of the necessary tools in design room, interior decoration, fashion design, architectural design, stage art design and other fields. There are many styles of Mike pens. Here are only two commonly used ones.

(1) water-based

Impervious, soluble in water, the painting effect is the same as watercolor. The shape of pen water has square thick head, pointed head and square head, which is suitable for drawing large area thick lines, while the pointed head is suitable for drawing thin lines and depicting details.

(2) Oiliness

Strong permeability, rapid volatilization, usually toluene as solvent, can be used on any surface, such as glass, plastic surface, with the effect of advertising color and printing color. Because it is insoluble in water, it should also be mixed with water-based markers to avoid damaging the traces of water-based markers. The advantages of Mike pen are quick drying, smooth writing, overlapping painting and covering various colors to make it shiny. And according to the nature of the Mike pen, the oil-water permeability is also different. Therefore, when painting, we must carefully understand the nature of paper and pen, take care of each other, and practice more, so that we can be handy and achieve remarkable results.

air brush

Pen-spraying is a precise tool, which can produce very fine lines and soft gradient effects. At that time, the role of pen spray was to help photographers and painters use it to modify the picture. However, the potential function of pen spray was quickly recognized by people, and it was widely used and developed. The artistic expression of spray pen is vivid, the description of objects is perfect and unique, the light and shade levels are delicate and natural, and the colors are soft. With the rapid development of science and technology, the pigments used in pen spray are increasingly diversified and specialized. Pen spray is used more and more widely. He has dabbled in various fields related to beautifying people's lives, and has obvious works in art halls, advertising posters, commercial illustrations, cover design, advertising photography, calendars, paintings, architectural paintings, comprehensive paintings and other fields. As a compulsory course in art colleges, pen-spraying technology has become a powerful expression technique in art modeling.

Pigments commonly used in painting

Generally speaking, any pigment with smaller particles after solvent blending can be used as paint.

Watercolor, resin and oil are three types of pigments, and watercolor is the most widely used. Here is an introduction to watercolor.

Watercolors include: watercolor, pastel (poster color), ink and wash, colored ink, traditional Chinese painting color and so on.

Watercolor: refers to a tube with translucent properties, fine particles, strong adhesion, but weak coverage. If it is applied with water pink, the effect will be better.

Water pink: widely used, pure pigment, bright color, opacity and strong hiding power.

Color of traditional Chinese painting: It has the characteristics of gouache and watercolor, and is an ideal spray painting.

Each color should master its own properties, such as black and other minerals with coarse pigment particles, which need to be ground before use. For example, pink, eosin, rose and other colors have poor hiding power, and there is often a phenomenon of flooding, so be careful when spraying. Ink is an opaque black pigment with fine and uniform color, which is the first-class pigment of black and white works of inkjet works. The pigment of color ink is composed of particles, which has unique luster, bright tone and good transparency. It can not only supplement the color of the picture, but also keep the clear structure of the picture, and can also be mixed with other pigments.

With the increasing use of spray pen, its pigments are becoming more and more specialized. Foreign countries have produced professional pen-spray pigments, which are favored by the art world, and the artistic language expression is more perfect and mature.

5. Computer

With the rapid development of science and technology, computer has become a new design method.
