The invention discloses a water bleeding ink control system and method. A master control module is a single chip microcomputer; a valve module comprises a plurality of solenoid valves; the single chip microcomputer comprises an input end, a first bidirectional interface, a second bidirectional interface and output ends, wherein an amount of the output ends is the same with the amount of the solenoid valves; a water writing cloth module is connected with a constant-pressure water pump; the constant-pressure water pump is connected with a water drawing pump through a pipeline; the water drawing pump is connected with a water source through the pipeline; the solenoid valves in the valve module are arranged in the water writing cloth module; the output end of the single chip microcomputer is connected with the solenoid valves in a way of one-to-one correspondence; the input end of the single chip microcomputer is connected with a WiFi (Wireless Fidelity) communication module; the first bidirectional interface and the second bidirectional interface of the single chip microcomputer are independently connected with a TF (Trans-Flash) reading module and a display; and the WiFi communication module is also wirelessly connected with mobile equipment arranged by a user. The method is combined to avoid the defect that eyes are always tired since no true ink display effects are obtained and eyes are filled with non-natural electronic screen light in the prior art.
