Abstract: PROBLEM TO BE SOLVED: To provide an efficient water-based flexo ink waste treatment method which does not use dangerous chemicals, such as strong acid and base, when the waste liquid of water-based flexo ink is treated, dispenses with pH control of the waste liquid to be treated, and therefore improves the workability.
SOLUTION: In the water-based flexo ink waste treatment method, a treating agent solution having a pH of 4-5 is added to the waste liquid containing resins composing the water-based flexo ink to precipitate the resins, and then aggregates are separated by a polymer coagulant.
