A Review on Development of Doctor Blade Assembly for Rotogravure Printing Machine

This paper describes a variety of fundamental research of Development of doctor blade assembly for rotogravure printing machine which the authors have recently performed. In flexible manufacturing industry Rotogravure Printing is not only popular but also very beneficial for printing huge quantity jobs. Now-a-days flexible packaging is a need in each and every segment as the demand is increasing on a fast pace and the market is being customer driven. To fulfil this need rotogravure printing machine is taken into consideration. Rotogravure printing machine has many variables for its optimum printing capability and superior quality. There are many sub systems/assemblies incorporated in the machine like Film tension control system, Auto registration control, Drying system, Solvent recovery system, Doctor Blade assembly, Gear drives. Out of all the systems and assemblies used Doctor Blade assembly is one of the most crucial parts that help in improving the printing quality of Rotogravure printing machine. At present doctor blade is adjusted manually over the printing cylinder.
