The correct way to use the marker pen Part 1

Instructions for the use of the marker pen

On the basis of line drawing, other materials and techniques can also be used. Deeper depictions, such as colored pencils, watercolors, etc., to add layers and three-dimensionality.

Marker coloring steps

Outlining

First, it is best to use a pencil to draft, and then use a pen to outline the bone line. When outlining the bone line, Be open, don't be rigid, and allow mistakes to happen, because markers can help you cover up some of the mistakes you make, and then put on markers. You also need to let go of markers and dare to draw, otherwise the drawings will be stingy and without tension. . Colors are best copied from actual colors. Some can be exaggerated to highlight the theme and make the picture impactful and attractive.

Overlap

Don’t overlap the colors too much, otherwise the picture will be dirty. You can overlap a small amount when necessary to achieve richer colors. Don’t use too many bright colors. You can use flowers and books, but if you want the individuality of the picture, then you can use it, but you must pay attention to tidying up and unifying the picture. Colors that are not available in markers can be supplemented with colored pencils, or colored pencils can be used to ease the jump of the strokes, but it is still recommended to emphasize the strokes.

Mark pen (Naeker) expression techniques

Mark pens are generally divided into two types: oil-based and water-based. The former's pigments can be diluted with toluene and have strong penetrating power, especially suitable for drawing on tracing paper (sulfuric acid paper); the latter's pigments are soluble in water and are usually used for drawing on tighter cardboard or coated paper. . In the drawing of indoor perspective drawings, oil-based markers are more commonly used. Here we also focus on the techniques of oil-based markers.

There are many types of marker pen colors, usually as many as hundreds, and the distribution of colors is divided into several series according to the commonly used frequency. Some of them are commonly used gray series with different color levels, which are very useful. convenient. Its pen tip generally has various thicknesses, and it can also draw lines with different thickness and effects according to different angles of the pen tip. Markers have the characteristics of fast drawing, rich colors and strong expressiveness, and are especially favored by architects and interior designers. Using the various characteristics of markers, you can create a variety of interior renderings. For example, if you use a marker pen to draw on sulfuric acid paper, you can use the room for blending of the colors before drying to produce the effect of watercolor fading; you can also take advantage of the translucent effect of sulfuric acid paper and use a marker pen to render on the back of the paper.

When using a metallic paint pen for the first time, you need to press the tip of the pen on the paper several times before the water comes out.

Usually, when drawing indoor performance pictures with markers, you first use a drawing pen (needle pen) to outline the main scenes and background objects of the indoor performance pictures, and then use markers to color them. The oily color layer and the ink line do not cover each other, and the color blocks have a strong contrast, giving it a strong sense of form.

To paint patches of color evenly, you need to move the brush quickly and evenly; to draw clear edges, you can use film and other objects to partially block; to draw a fade-out effect of color gradients , you can use a colorless marker pen for deblooming treatment; the color of the marker pen can be used to create various special effects with an eraser, a razor blade, etc. Markers can also be used with other painting techniques. For example, use watercolor or gouache to paint a large area of ??the sky, ground and walls, and then use markers to depict details or embellish the scenery to maximize strengths and avoid weaknesses and complement each other. Inkjet painting and comprehensive expression techniques.

Experience in using marker pens

Use oil-based needle pens (Sakura). Every time you draw, if you have just finished drawing the line drawing, use oil-based markers because they are all oil-based. So it's easy to spend. Unless you apply color the next night. According to my experience, you can color the reverse side of the sulfuric acid paper, or spend some money to go to a large printing shop. That kind of shop will have a machine that can do many things, such as copying and printing pictures.

You can give him your line draft and tell him you want to copy it, and he will put your drawing into the machine and it will be ready in 20 seconds. That machine can print pictures of any size, and it can be copied on sulfuric acid paper, and the price is very cheap. 15 yuan for A4. A1 is 12 yuan.

You can use a marker pen that won’t blur the photocopy line, which is an alcohol-based oil-based marker pen. Secondly, try to avoid repeated outlines of lines when painting to avoid damaging the paper.

After the painting is completed, there must be a certain drying time and do not touch it with your hands.

Generally, large professional landscape companies do this to prevent line drawings from being wasted by markers. Some people like to color the reverse side of sulfuric acid paper. There are several qualities of sulfuric acid paper on the market now. One of them looks the same as the high-quality one, but after coloring, you will feel that the transparency is not very good, and it looks very different from the front. Ash.

Suggestions for using markers

Beginners may wish to refer to the following methods when drawing this kind of representation

⑴First use cold gray or warm gray Use a marker to draw the basic light and dark tones in the picture.

⑵ During the process of using the pen, do not use the pen too many times. After the first coat of color dries, apply the second coat of color accurately and quickly. Otherwise, the color will bleed out and become turbid, without the transparent and clean characteristics of the marker.

⑶ When expressing with markers, most of the strokes are based on line arrangement, so regularly organizing the direction and density of the lines is conducive to forming a unified picture style. You can use methods such as arranging strokes, dotting strokes, skipping strokes, blurring, and leaving blank space. You need to use them flexibly.

⑷Mark pens do not have strong coverage, and light colors cannot cover dark colors. Therefore, in the process of coloring the renderings, light colors should be applied first and then covered with darker colors. And pay attention to the harmony between colors, avoid using too bright colors, and use neutral tones.

⑸ Simply using markers will inevitably leave shortcomings. Therefore, it should be used in conjunction with colored pencils, watercolors and other tools. Sometimes alcohol is used to mix it again, and magical effects will appear on the picture. The correct way to use the marker pen Part 2

How to use the marker pen? How to use markers to make your drawing better? What is the correct way to use markers? Is it difficult to learn painting? How should I learn to draw well? How to learn to draw? Presumably these are questions that beginners in painting often think about. They want to use markers to color, but don’t know the steps

So, today’s painting reactions have been collected and organized on the Internet, about how to do it. Here is a step-by-step tutorial on how to use marker pens for coloring. The tutorial is very simple, come and take a look:

First of all, we need to know that when using marker pens, the number of strokes should not be too many. After the first color has dried, apply the color a second time, it should be precise, and quick. Otherwise, the color will bleed through, creating a blurry shape that doesn’t have the characteristics of a transparent and clean marker~ Let’s get back to the point. The first step is to shape it, then trace it with a Sakura needle pen, and then use a marker. The marker must also be loosened. Don't be afraid to draw, otherwise it will be very stingy and without tension. Colors are best copied from actual colors, and some can be exaggerated to highlight the subject and make the picture impactful and attractive.

Secondly, markers should not overlap too many colors, as they can easily get smeared. It is different from water-soluble colored lead or gouache, the marker pen has bright colors and emphasizes the strokes, so some colors can be overlapped appropriately. However, if the color overlap is different, the second color can only be applied after the background color has dried. Do not use excessive force when using. If you cannot achieve the desired painting effect, you can use other painting tools at this time, such as colored pencils.

Mark pens are generally divided into two types: oil-based and water-based. The former pigment can be diluted with toluene and has strong permeability, making it especially suitable for tracing. The latter pigment is soluble in water and is usually used for painting on tighter cardboard or coated paper. Generally speaking, oil-based is used more for interior design.

Excessive and changing coloring.

Among the classifications of marker pen strokes, straight lines are the most difficult to grasp. You must pay attention to the intensity of starting and closing the pen to be light and even, and the strokes must be decisive to avoid serpentine lines.

The lines should be smooth, and the tip of the marker pen should be completely on the paper, so that the lines will be smooth. Use a combination of vertically intersecting brush strokes to express some changes in brush strokes to enrich the layers and effects of the picture. Be sure to wait for the first pass to dry before painting the second time, otherwise the colors will melt together and there will be no outline of the brush strokes. The strokes in different directions are relatively free and casual. You only need to change the direction at a small angle to apply. There are not many rules to follow. The key is to practice more and use more.

Marker block color practice

Common cube marker coloring expressions: first use a wood-colored marker to lightly draw on it, wait for it to dry, and then use colored pencils to paint on it. It has a wooden texture on its surface. For cylindrical objects, attention should be paid to the changes in light and dark transitions on the surface, and the boundary between light and dark should be clear.

Common geometric marker coloring expressions. Using one or two markers to create the relationship between light and dark, black and white and gray of a geometric entity is a common practice method in the early stages of practicing marker body blocks; using pen colors The superposition of weight and number of strokes directly affects the expression of the picture.

The brushstrokes of geometric objects should also be rehearsed according to perspective changes. The arrangement of the light-receiving surface and the emitting surface will make the brushstrokes more obvious. Pay attention to the connections between volumes and the changes in projection.

Using one or two markers to shape the relationship between light and dark, black, white and gray of a geometric unit is a common practice method in the early stages of practicing architectural marker blocks; the weight of the pen color and the number of strokes are all important. Directly affects the expression of the picture.

Analysis of plan drawing techniques

Mastery of overall coloring of planes;

Coloring of single and single group elements;

Center of the picture, The priority of coloring.

It is relatively simple to plan the plane coloring and grasp the general relationship. No need to get too detailed. When practicing, first practice the color expression of these individual flat plants.

The difference between two-dimensional plants, you can make the ground turf brighter, and vice versa for trees. The water surface should be drawn so that it is stable and stable, and do not make too many changes.

The coloring of highway pavement can be based on projection, and the areas with projection will be heavier. In other places, from near to far, the color is gray. Paint some bright colors on the ground as needed, such as light red, earthy red, grayish yellow, etc.

Steps for planning space expression

Differences in space coloring between sulfuric acid paper and carbon paper;

Virtual and real space coloring as a whole;

The relationship between light and dark in the picture, and the intensity of color and shadow.

Case 1

Step 1: Color the plants. Find two or three greens of different shades, changing from bright to dark from the direction of the light source. In addition, areas with grass can be painted in bright colors, while trees can be painted in dark colors. For places that need to be blurred in the distance, you can use a lighter or cooler color to blur the effect.

Step 2: As the color of the water, you can choose a pure blue color. If the water area is not large, just paint it flat without changing. If the area is large, you can add some light blue. Excessive, or leave some white blur.

Step 3: For the ground part, usually choose some light colors. It is not advisable to paint too much gray as it is easy to get dirty. Different places undergo certain changes depending on distance or the influence of light and shadow.

Step 4: Color the road part, usually gray. The changes can be near, deep, light, flat, or only the projected positions of trees and buildings.

The effect of the completed picture: the building is colored, focusing on the main building. First consider the color of the main building, which can be richer. Other building blocks only need to distinguish between light and dark surfaces, changing from near to far. Mainly focus on general things, Xiaodong does not need to draw too detailed.

Case 2

Step 1: Complete a bird's-eye view line draft of the planned area based on the architectural shape and site factors of the planned area. During the line drawing process, pay attention to the site volume relationship and spatial structure hierarchy, which is as clear as possible. The focus of the hand-drawn expression of planning and design is to highlight the building location, traffic network and functional zoning, and the background scenery should be weakened.

Step 2: Start coloring from the green plant area, mainly light colors, pay attention to leaving white space.

Step 3: Draw the main architectural planning part. After the first pass of natural color painting, strengthen the contrast between light and dark of the building group, paying attention to the near reality and far virtuality.

Step 4: Strengthen the contrast between light and dark in the overall space and adjust the relationship between near reality and far virtuality. Then adjust the color relationship of the background plants. You can use gray or blue to blend the brighter green.

Case 3

Step 1: Draw the perspective space according to three-point perspective, first draw the road network, and then locate the building location to increase the space. Add scenery and projection.

Step 2: Color the main building in the picture, from top to bottom, from dark to light, and the same goes for the entire building complex, from the front to the back, changing one by one.

Step 3: Add gray to the main projection on the ground, heavy near and light at far, and consider adding bright colors to the plant parts first.

Step 4: Give the distant plants a darker, more saturated green, and add some cool colors to moderate it. The ground material is added with some already used colors, and yellow is added locally.

The effect of the completed picture: add some light warm green to the glass part of the building as ambient light, but not too much, and add some highlights for a finishing touch. Add green to the top of the commercial layer, and finally improve some details such as dark areas.

Case 4

Step 1: Use a pencil to first locate the spatial perspective position, then use an ordinary marker pen and ruler to draw a line draft, paying attention to the virtual and solid in the center of the picture and the distant and near buildings.

Step 2: First choose a gray color and paint it on the backlight of the building. Make some changes appropriately to make it more vivid. There are also some places where shadows need to be painted.

Step 3: Choose gray-green to color the plants, and make some simple changes to the dark parts of the plants. The dark sides of the building can be changed to light blue or lavender.

Step 4: Use gray No. 1 or No. 2 to paint the road surface flatly. Use a light blue color to paint the water surface. Pay attention to the middle part of the entire picture to be relatively rich.

Finished picture effect: For the nearby water surface, use a darker blue to deepen it. You can consider using colored pencils. For the sky, add some blue colored pencils that are equivalent to the color of the water surface. Finally, deepen some of the architectural projections. For dark parts, you can use dark blue, dark gray, or even pure black. The correct way to use the marker pen Part 4

(1) The marker pen tip is divided into two types: flat tip and round tip. The front and side of the flat tip are colored in different widths. When using the pen, its shape characteristics can be used to form own unique style.

(2) Markers are not easy to modify after coloring. Generally, the color should be lighter first and then darker. When coloring, there is no need to spread the color all over the picture. Focus on the local depiction, and the picture will appear more lively and vivid. . Overlaying markers of the same color will appear darker. Overlaying multiple markers will have no obvious effect and will easily smear the color.

(3) Marker strokes and lines are the same as pencil drawings. They are also divided into two categories: freehand and tool. They should be selected according to different scenes and object shapes, textures, and expression styles, as shown in the picture.

(4) When modifying water-based markers, you can use a brush dipped in water to wash them away (it is difficult to wash them thoroughly). For oil-based markers, you can use a pen or cotton ball tip dipped in toluene to wash them off or lighten them.

(5) The writing style and fun of marker pens are lovable, but they are expensive. You can use oil brushes and gouache dipped in watercolor paint, and use rulers to move pens, and you can also get some of the fun of marker pens. . The Correct Use of Markers Part 5

1 Colored Pencils

Colored pencils play an important role in hand-drawing performance. Whether it is for conceptual plans, sketches or finished renderings, it is an excellent painting tool that is easy to operate and has outstanding effects. We can purchase any type and brand of colored pencils from eighteen to forty-eight colors, including "water-soluble" colored pencils.

2. Marker pens

Marker pens (also known as "marker pens") are one of the most commonly used painting tools in various professional hand-painted performances. Their types are mainly divided into oil-based and alcohol-based pens. Two kinds of sex. In the practice stage, we generally choose relatively cheap alcohol-based markers. This type of water-based marker pen comes in about sixty colors and can also be purchased individually. When purchasing, it is best to reserve more than 20 types according to personal circumstances, with gray tones as the first choice and do not choose too many bright colors. In order to be proficient in marker pen techniques, we must first have a basic understanding of the basic characteristics and writing techniques of marker pens. Marker pens are rich in color, easy to color, clear strokes, quick to draw, and come in a wide variety. The color will change when the dry and wet state changes, and the expression is very strong. Among them, gray series markers of different color levels are commonly used for color matching. The nibs of marker pens are generally divided into several types: thick and thin, square and round. When drawing expression diagrams, you can flexibly switch angles and inclinations to draw lines and strokes with different thicknesses.

3. Watercolor

Watercolor is the most representative and common coloring technique in hand-painted expressions.

Watercolor pigments have very fine particles, and when dissolved in water, they become crystal clear; when applied layer by layer on white paper, it is like the effect of layers of transparent cellophane. The characteristic of watercolor painting is that compared with other types of painting, the coverage and thick coating of oil painting create a thick and thick characteristic. Watercolor pigments are transparent, and thin coatings are used to maintain their transparency. The painting has a clear and transparent feeling. Use water to mix colors and play the role of water. It is flexible and natural, moisturizing and smooth, dripping and refreshing, and has endless charm.

4. Other tools

There are many types of tools for coloring architectural expressions, including correction fluid, pen rollers and other tools. These are not commonly used by beginners, but if you want to draw well For hand-painting, it is best to prepare more painting tools so that you can be handy.

Hue cycle, the mixture of colors "three primary colors", namely red, yellow, and blue. If these three colors are mixed in equal proportions, all colors will be absorbed and become black. The rest will be black. Adding two by two will generate a third color. This color theory is also applicable to marker pen coloring in practical applications. Marker pen color matching is very difficult. To adjust the color correctly, you only need to buy more ones with different color numbers. Apart from the pen, you have to rely on yourself to experience the subtle differences between colors. Among the classifications of marker strokes, straight lines are the most difficult to grasp. You must pay attention to the starting and closing of the pen to be light and even, and the strokes must be decisive to avoid snakes. Shape lines. The lines must be smooth, and the tip of the marker pen must be completely on the paper, so that the lines will be smooth. Since the use of vertically crossing combined strokes is to express some stroke changes and enrich the layers and effects of the picture, so be sure to wait. Do the first pass and then the second pass, otherwise the colors will melt together and there will be no outline of the strokes.

When using markers and colored pencils together, generally use markers first and then colored pencils. ;Do not overlap cold and warm. The correct way to use markers Part 6

Architect’s marker pen hand-drawing techniques

In many European and American architectural offices, designers do not only formally draw drawings In addition to using computer software to design plans, it is more common to express and communicate through hand-drawn sketches in the early stage. The process of plan design itself should be a scientific and reasonable system. Whether it is software drawing or hand-drawn representation, it should be designed for it. Content services, but the design of hand-drawn representations is more important. It is the beginning of the design process and allows architects to continuously improve the design concept and the expression of perceptual thinking. Sketching is undoubtedly the most effective and effective in solving problems that arise in design. The fastest.

Hand-drawn by Tadao Ando, ??combined with markers and colored pencils

More architects of the older generation admire sketches, believing that they can better capture the architect’s personality. Design inspiration. Cheng Taining, an academician of the Chinese Academy of Engineering and a master architect, said when talking about hand-drawn sketches, “I am very lucky to be engaged in the construction industry, because it is different from many industries and is a very creative job. Designers can see their sketches transform from drawings into real objects, and after seeing them, they feel that they still have a lot to improve. For me, it always appeals to me, makes me want to do it, makes me want to keep going. Some people are surprised that I can still draw sketches now. I said that if I didn't draw sketches, I wouldn't do this job. I don't want to just "point out" as some people suggest. The reason why I find this work interesting is that I can always feel that my thoughts are moving forward, so I have to draw sketches, and I have to control every stage from the plan, initial expansion to construction drawings, such as material selection, node design, etc. This allows me to see the entire process from draft to reality, which is a very pleasant thing and a process that attracts me very much. ”

Wright and other older architects pay more attention to the shape of the building when expressing with freehand. The characteristic of marker pen coloring is that they like to use light colors to express. For example, the sky is expressed with some light blue marker pen colors. , such as B[Blue]31, PB[Purple Blue]76, etc. When applying color, it should be both light and blocky, so that rich layers and changes can be drawn.

Cheng Taining’s hand-drawing, a combination of monochrome hand-painted style and software processing

As academician Cheng Taining said, now design institute architects generally work in the early stage of the plan in order to capture inspiration , you need to use tools such as pens to draw the plan shape or plane as quickly as possible with freehand, and then use markers to quickly color it. However, unlike painting, design hand-painting refers to quickly expressing the designer's design within a limited time. Concept, so this hand-drawing technique is very different from traditional painting methods. In the process of rapid expression of hand-drawing, the technique of marker pen is particularly important.

Here are some of the experiences accumulated by architects when using markers.

Among contemporary architects, such as Tadao Ando and Zumthor, they pay more attention to the materials of buildings. The color of markers tends to be cold gray markers with a full sense of design, such as German markers. iMark's CG [Cool Gray] and American AD's P181 series. These tones can better express the materials of fair-faced concrete and gneiss. The technique is to first press the projection, and quickly use a flat brush to paint the dark and bright parts. . Richard Meier, a representative of the White School, prefers to use the BG [Blue Gray] series to paint the dark parts of buildings when painting the dark parts of white buildings. This is a color tone for the dark parts of white buildings affected by the blue sky on sunny days. The sketch of the Cibeo Cultural Center drawn by Renzo Piano, a famous architect with varied styles, is completely consistent with the color numbers of R[Red]11, YR[Yellow Red]102, and YR[Yellow Red]106, just like The sun shines on the wood.

The architectural manuscripts of Italian architect Renzo Piano, mainly drawn with pens, markers, colored pencils, etc.

Renzo Piano (Renzo Piano) The sketch expression of this master architect from Italy may be the reason why many people fall in love with architectural design, and it is also the object of imitation by many designers. The sketches express clearly, the lines are extremely refined, and the occasional color embellishments make the pictures suddenly beautiful, lively and smart! It is a direct expression of confident and mature architectural design thinking. Piano once said: "...when a discovery is made, the eureka moment comes, and it works like a magic potion. In those moments, the accumulation of the past does not matter. Because you are a stuntman without a safety net For example, when I started sketching (I can't do anything without this step), I didn't know exactly what it would look like in the end. I allowed myself to be guided and realized that what I was writing wasn't that bad, so I continued. Go down. Much like "essay writing" your hands will lead you to the goal."

Helmut Kohl, an architect from the German GMP Architects firm, has some systematic introductions to marker pen techniques and usage techniques. (The following expressions are translated into Chinese)

When using markers to color design artwork, special attention should be paid to the following points: quick flat painting techniques, color matching, light and dark contrast, and texture processing , the shape of the stroke. As for these color schemes, it is recommended to use the German iMark marker pen to achieve a more pure look. Compared with this kind of marker pen, the color tone is consistent and rigorous, and the hue will be more accurate. In addition, the oval pen holder is comfortable to hold, ensuring that designers can use it for a long time without fatigue.

Any great architecture begins with a sketch, and the final building may differ from the sketch. Far away, but the most important thing cannot be ignored, just like the relationship between a tree and its seeds.

Sketch conception is more like an essay, a record, which can be drawn and read anytime and anywhere...

Zaha Hadid's sketch conception, using pens, markers, etc. Tools

The ideas drawn by hand in drawings are always the most original thinking, which is far from what software can express. This is why even though software technology is changing rapidly, architectural masters still respect the "original" hand-drawing. way. Markers have become the first choice of many design masters because they are available in thick and thin shapes, convenient and fast.

Designers prefer flat painting. The technique of flat painting is mostly used for coloring building facades. The key points are to be gentle when writing, to be fast when painting, and not to let the pen tip stay on the paper for too long. For a long time, avoid the two sections of brushstrokes from blooming. In addition, when writing, the wide pen tip should be completely pressed onto the paper to avoid rough effects and insufficient sharpness of the strokes. In terms of color matching, try to use more warm or bright colors in the front positions of the picture, and use more cold or gray colors in the back positions. In addition, it will be more reliable to match colors of the same color series together. For example, in iMark, different color numbers in the GY[Green Yellow] yellow-green series are suitable to be matched together, and different color numbers in the GB[Green Blue] cold green series are suitable to be matched together. If you use the GB series with the GY series, the screen will look dirty.

In terms of contrast between light and dark, it is recommended to first use black to overlay the projected position, and then paint the middle tone. The brush strokes can be swept into the black without leaving traces of smudge. German Mark The characteristic of the pen tip is that it is very strong and tough, which is very suitable for drawing on the hard surface of design drawings, and the texture expression is appropriate. You can leave appropriate white space in the bright parts of objects with lighter inherent colors. This method can increase the speed of strokes and increase the contrast of the subject, making the picture richer and more attractive. Texture processing is mainly controlled by the object's highlights, reflections, and mirror reflections. For example, if the floor material of the indoor hall is relatively smooth, it will definitely reflect the walls or sofas, etc. You can paint some colors of the walls and sofas on the ground. Of course, if the building is placed on the water, then the mirror reflection effect will be will be more obvious. Highlight (can be left blank or drawn with a highlight pen) and reflection are more commonly used in the texture of glass and metal. The difference between them is that the contrast between metal and light is stronger, and reflection is more obviously affected by the color of the environment.

The diversity of stroke shapes is more reflected in the drawing of soft objects such as plants or the sky. Designers can try to rotate the brush slightly to draw diamond-shaped or oval-shaped strokes with more direction changes. It will be much better than mechanical flat painting, and the soft objects expressed will be more "natural". Finally, if you feel that the connection of marker pen strokes in the entire picture is too stiff, using colored pencils to transition the picture is a good choice. Of course, the designer's design hand-drawn expression should not be too rich, and the colors should be unified and satisfy the designer's expression concept. optimal.
