Yes, there are different kinds of permanent ink, including dye-based and pigment-based inks. Dye-based permanent inks offer vibrant colors but may fade over time when exposed to light and water. In contrast, pigment-based inks are more resistant to fading and water, making them ideal for archival purposes. Additionally, permanent inks can vary in formulation for specific applications, such as fabric, paper, or plastic.
