These about shading technique of using pen.
Ink drawing is one of the most difficult aspects of drawing in general. You're in the shade and pictures by creating so-called "hard edge design." This is not an easy thing to do, especially if one tries to look a little realistic. You not look real - This is why it is often used in cartoons where the character is an insult to be used or humans or animals.
One of the most common techniques used is called pointillism. It is used for shade and is very common in many styles of ink drawing. This is a set of points close so that no capacity to see everything so far that the surface looks white. This is a relatively easy way to "shadow" in ballpoint pen. Man, the dot size and where they are made. They can also be used for different "forms" better (ie, which can be rounded or straight, and watch anyway of course).
Another technique is called hatching. It's simply a series of lines that are drawn across a surface, ranging from solid black to very far apart (depending on the size of the surface, they may get farther or still be relatively close to represent the white). It's a good technique for beginning artists, as drawing straight lines at varying intervals isn't hard. One should be careful that they GRADUALLY move apart, and that nothing is done suddenly. It won't create the necessary effect if this is done.
Cross-hatching is another element of design. It's a more complicated one, and is usually done by advancing artists. It's drawing lines in two directions (usually perpendicular, but not necessarily) to create shading. It's harder to do, as the intervals of both lines must be watched carefully. This is not recommended for beginning ink drawers, who should most likely start with regular hatching.
A lot of the design lies in the way the artist chooses to set up his/her paper. Overlap should be used (when necessary; in designs, but not always when characters are being created), and interesting negative space should be created as positive images are laid down. This is very eye-catching (the element of design itself) especially in this type of drawing, where there is rarely any color. Ink drawing usually means black and white.
Another thing that an artist can do to make things more interesting is vary the way the line is. This means edges (which can vary between sharp and soft) and, especially, line thickness. Many different pens are often used in order to create a contrast between certain sections. At least three different pens should be available, from around 0.3mm to 1mm. These will create even more "ideas" in the work - very thin lines tend to create sharper edges and clearer images, while thicker lines tend to blur things and make them more "user friendly."
Following these techniques, anyone can come up with a beautiful ink drawing. It's not too hard a skill to learn; it simply employs techniques which must be followed a little more closely than some other types of drawing. This will also enhance anyone's art skills, and will leave them with a good foundation for moving on to smearable materials and color.
