These marking fluids create translucent markings using a solvent-based dye and are typically used for low-volume applications such as reject marking. The marked surface can be seen through the markings, allowing multiple marking methods to be used simultaneously. They are more chemical- and wash-resistant than other dye-type marking fluids.

Solvent-based marking fluids use pigmented ink to create durable markings that are heavy-bodied and well-defined. They are more chemical- and wash-resistant than dye-type marking fluids.
