The new printing machine

TOYO INKI developed the new printing machine that you can't delete numbers once you print them. The new machine will prevent food companies from changeing the use-by date. However if the companies change labels themselves, it is not effective. There is irony in the fact that faked food problems make the new product. I think even if such new system are introduced in food companies, the scandal will not stop until workers' attitude doesn't change.
