Vehicle - What is a vehicle?
The liquid component of ink that holds the colourant and binds it to the substrate after drying. The vehicle is the carrier element; where the carrier in a label carries the adhesive and face material until the label is applied to a substrate, the vehicle in an ink facilitates the use of colourants by carrying the pigment or dye until it is applied to a surface. Vehicles can be made of glycol, oils, resin, solvents, or a combination of components. The type of vehicle used depends on the method of printing being used and each vehicle binds the colourant in a different way; some evaporate or dissolve leaving the colourant behind, others are absorbed into the substrate, and some will react with oxygen which causes them to harden and solidify.Go Back to Glossary
