RE: Printing Ink Waste Treatment Technology
Depending on many things (exact formulation, quantity, whether water based, to name a few), my first attempt would be by filtering. Other approaches would be boiling, coagulation via addition of flocculants, and coagulation via change of pH.

RE: Printing Ink Waste Treatment Technology
It is not an easy problem to solve. The major complication is that the pigments used for the inks are probably too small to be filtered out directly and very diluted.
Additionally it is very likely that you have dispersants worsening the problem. Depending on the components you may have to choose your solution. Floculants or precipitation may help you as Elguero mentioned, afterwards filtration could be applied.
