A variety of friction exists during gravure printing machine run-time. The friction between gravure roller and scraping blade has a great effect on the printing quality and gravure printing endurance. In this article, the friction between gravure roller and scraping blade is studied from the micro-contact perspective. The qualitative research of the factors that affect the friction between gravure roller and scraping blade is done, in order to confirm the effect law of the printing speed, scraping blade angle and gravure printing machine vibration on the friction between gravure roller and scraping blade.

In the latest type of gravure printing machines referred to as the shaft-less drive system, each gravure printing roller is driven by an individual servo motor, and all motors are electrically synchronized. The register error is regulated by a speed difference between the adjacent printing rollers. In order to improve the control accuracy of register system, an accurate mathematical model of the register system should be investigated for the latest machines. Therefore, the mathematical model of the machine directional register (MDR) system is studied for the multicolor gravure printing machines in this paper. According to the definition of the MDR error, the model is derived, and then it is validated by the numerical simulation and experiments carried out in the experimental setup of the four-color gravure printing machines. The results show that the established MDR system model is accurate and reliable.

in this paper, analysis of the fluid dynamics was carried out on hot air in drying mechanism of a gravure printing machine by applying the fluid dynamics and aerodynamics theories. The kinematical equation and the kinetic equation were established respectively and the RNG model was added according to flowing conditions of hot air. The CFD analysis model was established by adopting the computational fluid dynamics (CFD) method to implement dynamic simulation analysis on air hot in the drying mechanism. Uniformity of drying was improved through adding clapboard and a flow guide plate to optimize the structure of air nozzles, so that the hot air convolutes for multi times on substrate and the utilization efficiency was increased.
