Starting from this week, Lei Jun will irregularly sort out and share some problems encountered by our designers in their work, summarized experiences, some useful tools, their own works or some more creative cases, etc. I hope to develop and innovate with you in the field of industrial design!

Marker learning is a part of industrial design hand-drawing, which belongs to material light and shadow rendering. Now, many people use computer two-dimensional software instead of or in combination to render, in order to better express the authenticity and artistry of product design materials.

First of all, let's learn about the marker

Popular science

A marker is a special drawing color pen for writing or painting, which contains ink itself, usually with a pen cover, and generally has a hard pen tip. Today's markers are also divided into water-based and oil-based inks. Water-based markers are characterized by bright colors and clear brush strokes, and have a light color effect when combined with watercolor pens; The disadvantage is that it is heavy, and overlapping strokes will cause the picture to be messy. Oily markers are characterized by soft colors, elegant and natural strokes, and the effect is in place with the treatment of faded pens; The disadvantage is that it is difficult to control and needs more practice.

The marker has a special pen head, which is divided into a wide head and a narrow head. Different pens are needed in different places. The pigment of marker pen is volatile, and it is mostly used for quick drawing at one time.

Note: The marker is colored light first and then dark, and the marker itself is superimposed, so it is easier to draw layers first and then dark, and at the same time, it will not make the light marker head dirty.

When practicing marker, you can use the same shape to express it in different ways. Draw it once with black lead, then use a gray marker, and finally express it with multiple colors. The shades of black, white and gray are different, and the final effect is different. (Beginners are advised to try this method)

Several common methods for coloring markers

1. Parallel pen arrangement

Parallel pen arrangement is to arrange pens in one direction, such as horizontal direction, vertical direction or oblique direction. What should be paid attention to when arranging pens is that the hand holding the pen should be steady and the mood should be peaceful, one after another. The pen keeps moving backwards. The speed should be basically the same when moving, so that there will be no unevenness. The moving process can be connected with the pen, or a blank can be left-flying white. In this way, there are dense and sparse paintings, and there are masters and times, which are both unified and varied.

2. Overlapping typesetting method

Overlapping typesetting is widely used in in-depth expression. For example, in light colors, it is necessary to repeat typesetting and add heavy colors to reflect the three-dimensional effect of objects. In special objects, it is necessary to repeatedly run the pen to show the expected effect, and in many cases, the overlapping pen arrangement method will appear.

3. Cross-brush arrangement

After drawing the line draft, draw the sketch with colored lead, and first brush arrangement along the direction of the object when coloring. In the process of brush arrangement, in order to express the sense of material on the surface of the object, an angle is formed between brush strokes, and a certain texture is formed by emphasizing color at the overlap, so that cross-brush arrangement appears.

actual combat: take Spencer Nugent's marker hand-drawn tutorial as an example

Don't paint it, but draw it one by one, and control the strength of your hands evenly, otherwise it will have the effect of two ends. When two ends are heavy, draw another one with the same color number at last, which will generally cover it up.

Use a narrow-headed frame first, then draw from the dark part, first use a light color and then emphasize it, and the brush strokes should follow the curved surface of the shape.

in order to make the product more tough, finally use a black pencil to describe it.

Suggestions on the rendering of Mark's strokes:

First, grasp the big and put the small. That is, to express the overall concept of design, without paying much attention to the description of details.

second, foster strengths and avoid weaknesses. The drawing process is determined according to the drawing method that the designer is relatively good at.

3. Pay more attention to elements than colors. Monochrome is the main color, and local colors are set.

Marker itself is just a tool, and it is important for designers to keep it in mind. Therefore, it is suggested that designers who study markers should first look at some knowledge related to light and shadow, combine the above simple geometric relations, and then properly train your hand stability. I believe that you will draw a very neat and beautiful marker effect in ten days.
