The first part of the composition of an ink
The first part of the composition of an ink is the vehicle of the same. This is a varnish that is prepared at high temperature for a long period of time to define the series of inks to be manufactured. Depending on this cooking we obtain “penetration, viscosity, resistances, etc.” These vehicles or varnishes can be mineral based or vegetable based. In many cases the vehicle is obtained by mixing these mineral oils with the vegetables. At the present time it is the vegetables that are being imposed and in the last generation inks we only talk about vegetable bases.
