Dye-based ink is a type of ink commonly used in printers and art supplies. It consists of colorants that dissolve in a liquid, allowing for vibrant colors and smooth application. This ink is often favored for its ability to produce bright and vivid images, making it popular for photo printing and graphic design. However, dye-based ink is less water-resistant and may fade over time when exposed to light. It is typically used in inkjet printers and is ideal for projects where color quality is more important than durability. Users should consider the intended use when choosing between dye-based and pigment-based ink.
