INKJET LIQUID DISPOSING METHOD, INKJET RECORDING APPARATUS USING METHOD, TANK FOR STORING INKJET LIQUID, LIQUID ABSORBER FOR STORING INKJET LIQUID, AND DISPOSER OF INKJET LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a method for a disposing inkjet liquid whereby, even when two or more kinds of printing liquids which generate aggregation and viscosity increase when they are mixed are disposed in a state where they are mixed, the aggregation and the viscosity increase are suppressed.;SOLUTION: A first printing liquid including a divalent or more metal-ion, and a second printing liquid including an anion compound which reacts with the metal-ion to generate aggregation and viscosity increase when it is mixed with the first printing liquid, are mixed and disposed as a mixed waste liquid. The mixed waste liquid is disposed, including an aggregation and viscosity increase preventive agent which prevents reaction between the metal-ion and the anion compound.;COPYRIGHT: (C)2005,JPO&NCIPI
