What's the difference between needle pen drawing and pen drawing?

For the same scene, the needle pen can highlight its physical features.

The pen can better show its physical features.

Generally speaking, both pens and needle pens can be used for sketching. Compared with the pen, the lines drawn by the needle-tube pen are more symmetrical, slender, round and smooth, so the needle-tube pen painting is generally used to express the scenes with clear boundaries and realistic requirements, while the pen-and-ink painting is more inclined to freehand brushwork.

Needle pen is one of the basic tools for drawing drawings, which can draw uniform lines. The pen body is pen-shaped, and the pen tip is a hollow steel ring with a length of about 2cm, in which a movable fine steel needle is hidden. Swinging the needle tube pen up and down can remove the paper fiber blocking the pen tip in time. Check every pen when you buy it. The specific operations are as follows: 1. Swing the needle tube pen up and down to observe whether the thin steel needle with the pen tip is flexible and the length should be slightly longer than the pen tip for future use. 2. Open the pen cover and observe whether the integrity and flexibility of the suction bag are normal.

Pen, invented in the early 19th century, is a writing tool widely used by people. It is smooth, elastic and quite smooth to write. There are obvious brand names and models on the mouth of the pen sleeve or the surface of the pen tip. China's new pen-and-ink painting, an independent painting that is very popular in Europe, America and other places and gradually becomes hot in China, has gradually surfaced and so on.

This kind of pen writing tool, which mainly uses metal as the pen body, holds ink (mostly black or blue) through a hollow pen tube, and then writes through a duckbill pen through gravity and capillary action. It can be said that it is a writing tool of western calligraphy.
