What is the difference between water-based ink and oil-based ink for Marker Pen?

The water-based ink of a Marker Pen is mainly composed of water, pigments or dyes, surfactants, moisturizers, etc. These ingredients make water-based ink soluble in water, environmentally friendly, and easy to clean. Water-based ink usually has a lower viscosity and better fluidity, which allows it to smoothly cover the surface of the paper during use. At the same time, water-based ink dries faster, which is conducive to quickly completing painting or writing tasks.
Oil-based ink is mainly composed of pigments, oily solvents, resins, additives, etc. These ingredients give oil-based ink good adhesion and color saturation. Oil-based ink has a higher viscosity and strong permeability, and can form a solid film on the surface of paper, thereby enhancing the durability and water resistance of the color. In addition, oil-based ink also has better covering power and color vividness, which is suitable for painting or writing tasks that require rich color effects.
Because water-based ink contains more water in its composition, it usually dries faster. This allows water-based ink to quickly fix the color during painting or writing and reduce the phenomenon of smudges. However, water-based ink has relatively weak adhesion and may not adhere well on wet or smooth surfaces. Oil-based ink dries slowly and takes a long time to dry completely. But once dry, oil-based ink can form a solid film with strong adhesion and water resistance. This allows oil-based ink to maintain color durability and stability during painting or writing.
Water-based ink is suitable for various materials such as paper, cards, posters, etc. However, on some smooth surfaces (such as plastic, glass, etc.), water-based ink may not adhere well or fall off easily. In terms of color expression, water-based ink usually has bright tones and soft color transition effects. Oil-based ink is more suitable for smooth surfaces such as plastic, glass, metal, etc. Its color adhesion is strong and not easy to fall off. In terms of color expression, oil-based ink can present rich colors and strong visual impact. At the same time, oil-based ink also has good covering power and color layering, which can create richer color effects.
Water-based ink is easily washed off or blurred by water, so it is not suitable for occasions where water resistance is required. However, water-based ink has a greater advantage in terms of environmental protection because it does not contain harmful substances such as organic solvents. Oil-based ink has good water resistance and will not easily smudge even if it is accidentally stained with water. However, because it contains harmful substances such as organic solvents, oil-based ink has certain risks in terms of environmental protection. You need to pay attention to ventilation and protective measures when using it.
The brush strokes of water-based ink are relatively soft, and the smoothness is higher when writing or drawing. This makes water-based markers more suitable for tasks such as writing, sketching, and detail depiction. At the same time, because water-based ink is easy to clean and change colors, it is also more suitable for beginners and children. The brush strokes of oil-based ink are relatively hard, and a certain amount of pressure is required when writing or drawing. This makes oil-based markers more suitable for tasks such as drawing thick lines, filling color blocks, and drawing strong color effects. At the same time, because oil-based ink has good covering power and color vividness, it is also more suitable for professional painters and designers.
