Below, we will analyze the issues related to poor quality of cartridge ink in detail to help you better understand and deal with this problem. I. Common Issues and Their Impact: 1. Poor Writing Smoothness: Poor-quality ink often causes writing difficulties such as blurry or disconnected letters, significantly affecting the writing results. 2. Color Fading: Inferior ink tends to have a dull color that cannot achieve the desired writing effect. This is particularly prominent in situations where clear and vibrant handwriting is required, such as student assignments or business documents. 3. Poor Ink Permeability: Poor ink permeability can lead to smearing and bleeding of the ink, even penetrating to the back of the paper, affecting the beauty of the writing and paper quality.

4. Potential Health Risks: Some inferior inks may contain harmful substances that may pose potential health risks if used for a long time. For example, certain chemical components may irritate the respiratory tract and skin, or even cause allergic reactions.

II. How to Choose High-Quality Cartridge Ink: 1. Check Brands and Reputation: Choose well-known brands and products with good reputation, which usually have better quality assurance. Avoid purchasing non-branded products or low-quality inks at low prices. 2. Observe Ink Color and Transparency: High-quality ink is usually bright in color and high in transparency. When purchasing, you can compare the color and transparency of different products to choose the ink that suits your needs. 3. Pay Attention to Ink Permeability: Before purchasing, you can learn about the permeability of the ink to choose an ink that suits your writing needs. For situations that require clear handwriting, choose an ink with moderate permeability.
