How to draw with a pen?
First, hold it straight. It's like a ping-pong backhand.
Easy to control, especially when drawing a straight line, the advantage of direct grip is obvious. For people with small hands, holding it straight is more comfortable.
Second, cross grip. Similar to the horizontal stroke in table tennis.
It is not easy to get tired, and you can choose to hold it horizontally when you work for a long time. For lefties, the horizontal grip is also more comfortable.
Third, the main steel needle and the main shaft in the pen are made of precision ultra-fine steel.
The nib directly controls the adjustment of the diameter and direction of the pen. Be careful when cleaning, and be careful not to damage your head. Once the main steel needle is damaged, the whole pen will be scrapped.
Fourthly, the adjustment knob of displacement and caliber is located at the end of the pen.
By adjusting this knob, the discharge amount of paint at the front end can be controlled, so as to control the thickness of paint sprayed on the surface of the object. The nozzle is located at the front of the pen and should always be kept clean.
Pen has been widely used. When using pen, you must pay attention to the air pump. Only using air pump can you spray paint.
Advantages of inkjet pen:
Compared with the coloring pen, it can spray paint more evenly, control the thickness of paint better, and show subtle differences such as the weight and lightness of color, so it is easy to spray color on a large area without chromatic aberration; Compared with color spray cans, it is no longer a monotonous color, and you can freely match various colors according to your own preferences and needs, completely unconstrained.

Pen spraying principle
Pen-pen is a precision instrument, which can produce very fine lines and soft gradient effects. At that time, the role of inkjet pen was to help photographers and painters use it to modify the picture. However, the potential function of inkjet pen was quickly recognized by people, and it was widely used and developed. The artistic expression of the pen is vivid, the depiction of objects is perfect and unique, the light and shade levels are delicate and natural, and the colors are soft. The pen must be used in conjunction with the air pump, because the pen must have a gas eruption to spray paint.
With the combination of valve stem, the airflow and pigment flow are controlled, and the plate plug can be started up and down and can slide horizontally. When sliding horizontally, the rear connecting rod of the stopper rod pushes the throttle needle to control the color quantity of the incoming airflow. By pulling back the throttle needle, the cross-sectional area of the nozzle gap is gradually increased, and the injection angle of the mixed gas is also increased. The spray sample is a covering composed of countless fine particles. Every particle is atomized and sprayed on the screen in a saturated state. At the moment of atomization, the water in the color evaporates rapidly, and the color sprayed on the screen is almost dry. The dry and wet change of color is very small, and the change of color is easy to grasp.
The painting with spray painting is vivid and unique, with soft colors and delicate and natural light and shade.
