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.

These marking fluids use transparent water-based dye to create translucent markings 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. Their markings are water soluble which makes them ideal for temporary marking, such as quality control. These marking fluids are nontoxic and nonflammable.
