In order to study the influence of key process parameters on the ink quantity of UV color ink gravure printing,an experimental study was carried out between the process parameters of gravure printing and the ink quantity.By setting printing parameters through gradients and controlling the variables of printing parameters,printing experiments were conducted on the Ziyun cigarette label using the Cerutti gravure printing machine.Finally,the printing samples were weighed.The relationship between heating temperature(ink viscosity),mesh depth,printing pressure,printing speed,and ink transfer rate was obtained,and the optimal process parameters for UV ink gravure printing of cigarette labels were determined.Under these printing parameters,namely a mesh depth of 60μm,heating temperature 65.3℃,printing pressure 41.8psi,printing speed 160.3m/min,the quality of cigarette label printing can meet the requirements of the enterprise.It provides theoretical support for gravure printing ink flow control.
