I. Ink Quality
Ink is the core of pen refill writing, and its quality determines the smoothness and color of the writing. Good ink should have the following characteristics: 1. Bright colors: High-quality ink can present a rich color palette, making written or painted works more vivid. 2. Quick drying speed: The ink should dry at a moderate speed to prevent blurred or smudged characters. 3. Smoothness: Good ink flows smoothly at the tip of the pen, without any issues such as ink cuts or stalls. II. Tip Touch Feel Besides ink quality, the touch feel of the pen tip is also an important factor affecting the writing experience. A good pen tip should have the following characteristics:1. Fineness: The fineness of the pen tip directly affects the smoothness of writing and the clarity of the characters. A fine pen tip can better capture changes in writing pressure and angle, resulting in fuller characters.
2. Moderate hardness: The hardness of the pen tip should be moderate, not too soft to cause blurred characters and not too hard to affect the comfort of writing. 3. Feedback: A high-quality pen tip provides good feedback, allowing the writer to clearly perceive the contact between the pen tip and the paper surface, thereby better controlling writing pressure and angle. III. Comprehensive Experience Combining ink quality and tip touch feel, we can obtain a comprehensive writing experience. A high-quality pen refill should provide a smooth writing feeling, clear characters, comfortable writing experience, and good drying speed. Such a pen refill can allow writers to enjoy the joy of writing and improve their work efficiency.
