BEIJING— Masterwork is set to become Heideleberg's largest shareholder with  a 8.5% stake in Heidleberg Germany. Heidelberg said the move will take its long-standing sales partnership with Masterwork “to a whole new level” and that the proposed capital increase is to be used to accelerate Heidelberg's "go digital Program".The deal is expected to take place  by the end of the first quarter of 2019. Masterworks is China's largest  post-press manufactuer of die-cutters and hot-foil embossing machines. Since  Masterworks acquired Heidelberg's post-press packaging technology about five years ago, they have had a very close relationship with Masterwork. Masterworks has said they have no intention today  to increase its stake further .
