Pigment black 7 and soft water mix according to the ratio of 1:1 and 30% pigment binder add respectively carries out mix and blend in the kneader, churning time is that 20min, kneading temperature are 70 ℃, then carry out replacement dewatering: leave standstill after for some time makes oily water separation, kneader is tilted the water on upper strata is poured out, obtain once to mediate mixture;
Step 2, secondary are mediated:
Add described 100% the soft water of once mediating the mixture total weight amount of step 1 in the kneader, carry out remix and stir, behind the churning time 10min, mediating temperature is 60 ℃, then replacement dewatering carries out next step after the soft water specific conductivity reaches 1,000 μ S/cm;
Step 3, vacuum hydro-extraction:
Kneader is vacuumized, and vacuumizing temperature and be 95 ℃, vacuum tightness is 0.06MPa, further extrudes residual moisture;
Step 4, mix and blend:
Add weight percent in the kneader again and be 37% pigment binder, and fully mix, churning time is that 120min, whipping temp are 75 ℃, obtains ink mixture;
Step 5, grinding:
The described ink mixture that step 4 is obtained is put into three-roller and is ground, and grinding temperature is 60 ℃, be ground to fineness less than 7.5 μ m after, obtain the mixed base China ink;
Step 6, preparation planographic ink finished product:
