Printing on carrier bags

Through reading up on the printing process of plastic bags, it has been highlighted that another process used is through the use of an offset printer. This involves the design being made on a metal plate so that the ink can run over and then be printed onto the plastic. This is an efficient and fast way of printing a number of different designs. Although not identified to relate to all, this is one of the ways that a number of plastic carrier bags are printed. This could be one of the ways that the designs would be printed if they were to be commercially used.
