专利汇可以提供Ink viscosity regulator专利检索,专利查询,专利分析的服务。并且PURPOSE: To enable strict regulation of viscosity, by a method wherein the pulsating number of a pulsation pump required for reaching the critical state just before the quality of printing is affected by the increase of viscosity with the passage of time is established and volatile solvent is supplemented at the time when the established value has reached zero.
CONSTITUTION: After being sucked via the sucking pipe 18 connected to a diaphragm pump 16, the gravure ink in an ink pan 10 is returned again to the ink pan 10 from a returning pipe 20 and always, in a flowing manner, refluxed during printing operation. Then, when a preset value is decreased by each one pulse by the input of the pulsating answer signal of the diaphragm and lastly has reached zero value, an electric command is outputted to the solenoid valve 24 of a solvent tank 22 and volatile solvent is supplemented to the gravure ink from a feed pipe 26. By directly checking the viscosity of the ink in the ink pan thus, its viscosity can be strictly regulated.
