PROBLEM TO BE SOLVED: To provide an ink viscosity regulator simply and compactly mounted in a printer. SOLUTION: A pressure sensor 6 is provided at the ink supply side route 5a of the ink circulating route 5 of a flexographic printer. The ink pressure feeding pressure detected by the sensor 6 is compared with an upper limit value set to a controller 9. When the detected ink feeding pressure exceeds the upper limit value, a solenoid valve 7 mounted at a liquid supply tube 8 is opened by the controller 9, and simply, compactly mounted irrespective of newly provided or existing printer to constitute to supply a dilute liquid to an ink container 1. |
