Printing inks differ in their composition and in their ability to be removed from paper in the deinking process. I was the purpose of this research work to make a comparison of this deinkability, for common printing inks.
In this experimentation, five inks were compared. These were a linseed oil base ink, a mineral oil base ink, a moisture set ink, a alkyd base in and a rubber base ink. Deinking was done using a standard deinking formula and varying only the concentration of the deinking agent.
The results show a marked difference in concentrations of deinking agent necessary for deinking different inks. Some of the inks deinked at low concentrations of deinking agent, while others required higher concentrations. The rubber base ink could not be deinked with the method used in this experimentation.
